Wireless communication node and method for configuring donor and service antennas therefor

Abstract

A wireless communication node employs a method for configuring its antennas at or after node installation. The antennas are positioned in a predetermined arrangement and at fixed positions. The node includes the antennas, one or more processors, and a memory storing processor-executable instructions for the processor(s). Responsive to the processor-executable instructions, the processor processes wireless signals received by a first antenna and determines whether such processed signals meet base station discovery criteria. If so, the processor designates the first antenna as a donor antenna and designates some or all of the remaining antennas as service antennas. If not, the processor processes wireless signals received by a second antenna and determines whether such processed signals meet the base station discovery criteria. If so, the processor designates the second antenna as the donor antenna and designates some or all of the remaining antennas, including the first antenna, as service antennas.

[0001] The present disclosure relates generally to an- tennas and antenna selection schemes. More particu- larly, but not exclusively, the present disclosure relates to a wireless communication node, such as a repeater, and a method for configuring donor and service antennas for such a node. BACKGROUND

[0002] Successful deployment of 5G systems utilizing new 5G millimeter wave (mmWave) bands are complex, having multiple input, multiple output (MIMO) antennas or other antenna structures and employing emerging standards, such as millimeter wave or C-band 5G, which require additional improvements in performance para- meters. Millimeter wave 5G systems may also require more base stations due to high propagation losses of mmWave signals, especially in urban and other settings. However, the costs for deploying base stations to in- crease coverage and capacity of mmWave 5G networks in urban settings can be substantial when factoring in the costs of equipment, newpoles, site acquisition, acquiring utility power, and running fiber backhaul for such installa- tions. Therefore, amore cost-effective solution is needed for densification of mmWave 5G and other generally line of sight communication systems.

[0003] All of the subject matter discussed in the Back- ground section is not necessarily prior art and should not be assumed to be prior art merely as a result of its discussion in the Background section. Along these lines, any recognition of problems in the prior art discussed in the Background section or associated with such subject matter should not be treated as prior art unless expressly stated to be prior art. Instead, the discussion of any subject matter in the Background section should be treated as part of the inventor’s approach to the particular problem, which, in and of itself, may also be inventive. SUMMARY

[0004] According to one exemplary embodiment, a wireless communication node includes, inter alia, donor andserviceantennas, anactuator (e.g., a rotary actuator, such as a servo, stepper, induction, or other type of motor), one or more processors, and a memory. The donor and service antennas may be implemented as phased array antennas, each with an array of electro- nically controllable antenna elements. The donor and service antennas are positioned in a predetermined ar- rangement about a central axis, which may be a central axis of a support structure to which the antennas are coupled. Each donor antenna is operable to communi- cate wireless signals with (e.g., transmit wireless signals to and receive wireless signals from) a base station after the base station (e.g., a 5G gNodeB or gNB) has been discovered by the wireless communication node. Each service antenna is operable to communicate wireless signals in one or more service or coverage areas (e.g., transmit signals to and receive signals from mobile de- vices, tablet computes, wireless routers, or other user equipment located in the service area or areas). In one exemplary embodiment, the wireless communication node is aerially mountable, such as to a streetlight, pole, or other structure. In another exemplary embodiment, the wireless communication node may function as an infra- structure component, such as a repeater, a relay node, a small cell node, an access point, a gateway, or a router of awireless communication system (e.g., ammWave orC- band 5G system) or as an integrated access and back- haul (IAB) node in a 5G IAB network. In a further ex- emplary embodiment, the wireless communication node may include four antennas in total, one donor antenna and three services antennas, with each antenna being configured substantially orthogonal to its neighboring antenna to form a generally rectangular arrangement. Such an arrangement serves to improve radio frequency isolation between the antennas. In another exemplary embodiment, the wireless communication node may in- clude three antennas in total, one donor antenna and two service antennas, with each antenna being configured approximately120-degrees from itsneighboringantenna to form a generally triangular arrangement. In other em- bodiments, two antennas or five or more antennas may be used depending on the quantities and geographies of the coverage areas to be serviced by the service anten- nas.

[0005] The processor(s) is operable to, inter alia, com- municate control signals to the actuator and process wireless signals received by at least the donor antenna. For example, the processor may be operably coupled, directly or indirectly, to the actuator and through conven- tional wireless transceiver circuitry to the donor antenna and / or the service antennas. Thememory stores instruc- tions (e.g., executable code) for execution by the pro- cessor. Such instructions, when executed by the proces- sor, cause the processor to perform various steps or tasks. For example, such instructions may cause the processor to process a first wireless signal received by the donor antenna and determine whether the first wire- less signal meets base station discovery criteria to en- able discovery of the base station. In the context of the present disclosure, a wireless signal received by the donor antenna meets base station discovery criteria if the wireless signal meets or exceeds the base station discovery criteria. The base station discovery criteria may include one or more of a base station identifier, signal strength or other signal quality criteria (e.g., threshold or level), channel loading criteria, and band- width criteria. For example, the base station discovery criteria may include parameters, thresholds or other cri- teria for establishingwhether thewireless signal received by the donor antenna: (a) is of sufficient quality for decod- 5 10 15 20 25 30 35 40 45 50 55 3 3 EP 4 664 676 A2 4 ing by the wireless communication node or user equip- ment with an acceptable level of accuracy, (b) meets or exceeds a threshold for signal strength, (c) includes a base station identifier, (d) includes data or information from which base station loading can be determined, and / or (e) includes data or information relating to channel frequencies and bandwidths supported by the base sta- tion.

[0006] When the first wireless signal meets the base station discovery criteria, the stored instructions may cause the processor to provide one ormore beamcontrol signals to the donor antenna to cause the donor antenna to form a beam pattern in a direction of the base station. According to the present disclosure, formation of a beam includes any one or more of beamforming, beam steer- ing, spatial filtering, or other known or future developed beam formation techniques. In an exemplary embodi- ment, the formed beam pattern is sufficient to achieve signal strength above a threshold for subsequent signals received from the base station.

[0007] When the first wireless signal does notmeet the base station discovery criteria, the stored instructions cause the processor to communicate a first control signal to the actuator. The actuator is operable to rotate the donor and service antennas as a group about the central axis in response to control signals from the processor. The first control signal received by the actuator from the processor may cause the actuator to rotate the antennas as a group incrementally clockwise (e.g., to the right) or counterclockwise (e.g., to the left) by an angular displa- cement relative to the current position of the group of antennas. In one exemplary embodiment, such angular displacement may be between about five and about ten degrees clockwise or counterclockwise relative to the current position of the group of antennas. Where the group of donor and service antennas are coupled to a support structure defining the central axis, the actuator may rotate the support structure about the central axis to thereby rotate thedonor and service antennas asagroup about the central axis.

[0008] After the group of antennas has been collec- tively rotated by the angular displacement, the stored instructions cause the processor to process a second wireless signal received by the donor antenna and de- termine whether the second wireless signal meets the base station discovery criteria. When the second wire- less signal meets the base station discovery criteria, the stored instructions may cause the processor to provide one ormore beamcontrol signals to the donor antenna to cause the donor antenna to form a beam pattern in a direction of the base station. When the second wireless signal does not meet the base station discovery criteria, the stored instructions may cause the processor to com- municate a second control signal to the actuator. The second control signal may cause the actuator to rotate the antennas as a group incrementally by another angu- lar displacement, which may be the same angular dis- placement as was used upon determining that the first wireless signal did not meet the base station discovery criteria or a different angular displacement. For example, where the stored instructions implement a coarse and fine tuning methodology, the angular displacement used after determining that the second wireless signal does not meet the base station discovery criteria may be less than the angular displacement used in response to de- termining that the first wireless signal did not meet the base station discovery criteria. By contrast, where the stored instructions implement a uniform rotation metho- dology, the angular displacement used after determining that the second wireless signal does not meet the base station discovery criteria may be substantially the same as the angular displacement used in response to deter- mining that the first wireless signal did not meet the base station discovery criteria. The stored instructions may cause the processor to continue an iterative process- rotate-process approach until a wireless signal is re- ceived by the donor antenna that meets the base station discovery criteria.

[0009] After the donor antenna has received awireless signal that meets the base station discovery criteria, the stored instructions may cause the processor to provide one ormore beamcontrol signals to the donor antenna to cause the donor antenna to form a beam pattern in a direction of the base station. The stored instructionsmay also cause the processor to establish a wireless connec- tion with the base station (e.g., where the wireless com- munication node is a small cell node). Additionally, the stored instructions may cause the processor to provide one or more beam control signals to each service anten- na to cause the service antenna to form a respective beampattern toprovidewirelesscoverage tooneormore service areas or a respective service area. According to one exemplary embodiment, the beam control signals provided to the donor and service antennas are such that they cause thedonor antenna to formabeampatternwith a higher gain and narrower beam width than a gain and beam width of a beam pattern formed by one or more of the serviceantennas.Accordingly, thebeamformingcon- trol signals provided to a donor antenna or a service antennamay be used to forma beampattern of a desired gain and a desired beam width directed or steered to a desired azimuth and / or a desired elevation. Further, the donor antenna, the services antennas, or both may in- clude respective arrays of antenna elements configured into a respective phased antenna array. In such a case, the processor may provide beam control signals to the respective phased antenna array to cause the phased antenna array to form a desired beam pattern directed toward the base station (for the donor antenna) or direc- ted toward a service area (for a service antenna).

[0010] According to an alternative embodiment, the donor and service antennas may form part of, or be contained in, an antennamodule that includes a housing, a cover, or someother protective enclosure. Theantenna modulemay also include a support structure to which the donor and service antennas are coupled. Further, the 5 10 15 20 25 30 35 40 45 50 55 4 5 EP 4 664 676 A2 6 antenna module and / or the support structure may be attached to another electronic device or module, such as a streetlight mountable device, which includes other circuitry of the wireless communication node and option- ally circuitry for performing other functions, such as streetlight luminaire control, power metering, location services, and so forth. In such a case, or where the antennas are coupled to a support structure without the antenna module, the antenna module or the support structure may include a light pipe that directs ambient light to a photo sensor in the antennamodule, the support structure, or an electronic device to which the antenna moduleor the support structure is attached.For example, where the antenna module or the support structure is attached toanelectronicdevicemounted toa luminaireof a streetlight and the electronic device includes a photo sensor to facilitate performance of light control functions, the antennamodule or the support structure may include a light pipe to permit ambient light to reach the photo sensor of the electronic device. In this embodiment, the electronic device and the antenna module or the support structuremay form all or part of the wireless communica- tion node and the electronic device may include the one or more processors, the memory, and various other components of the wireless communication node.

[0011] According to a further embodiment of the pre- sent disclosure, thestoredprocessor-executable instruc- tions may cause the processor to communicate an initial control signal to the actuator after detecting that the wireless communication node is powered on. In this case, the initial control signalmay be part of an automatic configuration operation for the wireless communication node and cause the actuator to rotate the donor and service antennas as a group (e.g., rotate a support structure to which the antennas are coupled) by prede- termined angular displacement increments (e.g., 5‑10 degree increments) until completing a predetermined amount of displacement or rotation (e.g., 90 degrees, 180 degrees, 270 degrees, or 360 degrees). At each angular displacement increment, the processormay pro- cess one or more wireless signals received by the donor antenna to determine whether the signal or signals meet base station discovery criteria to enable base station discovery. The processor may discover a base station onwhich to lockor towhich toestablishaconnectionprior to completion of the automatic configuration process or may collect candidate base station data during the auto- matic configuration process and select (discover) the base station on which to lock or to which to establish a connection upon completion of the automatic configura- tion (e.g., after the group of antennas have been rotated through the entire predetermined amount of angular displacement).

[0012] According to another exemplary embodiment of the present disclosure, a wireless communication node includes an antenna module, donor and service anten- nas, an actuator, one ormore processors, and amemory. The antenna module includes a support structure defin- ing a central axis. The antennas are oriented in a pre- determined arrangement about the central axis and coupled to the support structure. Theactuator is operable to rotate the support structure about the central axis in response to one or more control signals. The proces- sor(s) is operable to communicate the control signals to the actuator and process wireless signals received by at least the donor antenna. The memory stores processor- executable instructions that, when executed by the pro- cessor, cause the processor to perform an antenna con- figuration routine.

[0013] For example, according to this exemplary em- bodiment, the stored instructions cause the processor to process a first wireless signal received by the donor antenna and determine whether the first wireless signal meets base station discovery criteria to enable a con- nection with a base station. Awireless signal received by the donor antenna meets the base station discovery criteria if the wireless signal meets or exceeds the base station discovery criteria. When the first wireless signal does not meet the base station discovery criteria, the stored instructions cause the processor to communicate a first control signal to the actuator, which causes the actuator to rotate the support structure by an angular displacement. After the support structure has been ro- tatedby theangulardisplacement, thestored instructions cause the processor to process a second wireless signal received by the donor antenna to determine whether the second wireless signal meets the base station discovery criteria. When the second wireless signal does not meet the base station discovery criteria, the stored instructions cause the processor to communicate additional actua- tion control signals to the actuator to rotate the support structure incrementally by angular displacements until the processor determines that at least one received wireless signal meets the base station discovery criteria. When a wireless signal received by the donor antenna meets the base station discovery criteria, the wireless communication node, through operation of the proces- sor, may establish a connectionwith the base station that transmitted the criteria-meeting wireless signal. After or as part of establishing the connection, the stored instruc- tions may cause the processor to provide beam control signals to the donor antenna to cause the donor antenna to form a desired beam pattern in a direction of the base station.

[0014] According to another exemplary embodiment of the present disclosure, a wireless communication node includes donor and service antennas positioned in a predetermined arrangement about a central axis, an actuator, one or more processors, and a memory. The actuator is operable to rotate the antennas as a group about the central axis in response to one or more control signals. The processor(s) is operable to communicate the control signals to the actuator and process wireless signals received by at least the donor antenna. The memory stores processor-executable instructions that, when executed by the processor, cause the processor to 5 10 15 20 25 30 35 40 45 50 55 5 7 EP 4 664 676 A2 8 perform an antenna configuration routine.

[0015] For example, according to this exemplary em- bodiment, the stored instructions cause the processor to communicate at least one control signal to the actuator to cause the actuator to rotate the plurality of antennas as a group in angular displacement increments until complet- ing a predetermined angular displacement (e.g., 90 de- grees, 180 degrees, 270 degrees, or 360 degrees). The stored instructions also cause the processor to process one or more wireless signals received by the donor antenna at each angular displacement increment to col- lect candidate base station data. The stored instructions further cause the processor to select a candidate base station to which establish a connection from the candi- date base station data and provide beam control signals to thedonorantenna tocause thedonorantenna to forma desired beam pattern in a direction of the selected base station. The stored instructions may also cause the pro- cessor to compare the candidate base station data for each candidate base station to base station discovery criteria and select the candidate base station having candidate base station data that meets the base station discovery criteria.Where the candidate base station data indicates that signals from two or more base stations meet the base station discovery data, the stored instruc- tions may cause the processor to select the base station with the best overall candidate base station data. The stored instructions may further cause the processor to provide beam control signals to each service antenna to cause theserviceantenna to formadesiredbeampattern directed to a respective service area. In this embodiment, where the predetermined angular displacement is great- er than 180 degrees, the stored instructions may cause theprocessor to send control signals to theactuator soas to rotate the donor and service antennas as a group no greater than 180 degrees in either direction (clockwise or counterclockwise) from a starting position in order to mitigate any twisting of cables that may be connected to the antennas, an antenna module that includes the antennas, or a support structure to which the antennas are coupled.

[0016] According to another embodiment of the pre- sent disclosure, an exemplary method is provided for configuring donor and service antennas of a wireless communication node for operation in a wireless commu- nication system that includes at least one base station andat least thewireless communication node. Themeth- od may be performed by one or more processors and / or other components of the wireless communication node. According to this embodiment, the donor and service antennas are configured in a predetermined arrange- ment about a central axis.

[0017] According to the exemplary method, a wireless signal received by the donor antenna is processed and a determination is made as to whether the wireless signal meets base station discovery criteria. When the wireless signal does not meet the base station discovery criteria, the donor and service antennas are rotated as a group about the central axis by an angular displacement. After the rotation, another wireless signal received by the donor antenna is processed and a determination ismade as to whether that wireless signal meets the base station discovery criteria. When the wireless signal meets the base station discovery criteria, a beam pattern is formed for the donor antenna in a direction from which the wire- less signal was received (e.g., in a direction of the base station). Thedonor antennabeampatternmaybe formed to achieve signal strength above a threshold for subse- quent signals received from the base station. When the wireless signal does not meet the base station discovery criteria, the donor and service antennas are rotated as a group about the central axis by another angular displace- ment. The latter angular displacement may be the same asordifferent than the formerangulardisplacement (e.g., when using a coarse tune / fine tune process, the angular displacements may change (e.g., become smaller) over the course of the configuration process). After or during formation of the donor antenna’s beampattern, a respec- tive beam pattern is formed for each service antenna to provide wireless coverage to one or more service areas or its respective service area.

[0018] Thus, according to this exemplary embodiment, thewireless communication nodeuses an iterative signal processing and antenna group rotation methodology to automatically configure or position the group of donor and service antennas to enable the donor antenna to establish a high quality wireless communication signal path with a base station. Such a methodology may be very beneficial, both performance-wise and economic- ally, where the wireless communication node is installed in the system at a location where a support structure for the node and utility power are already available, such as at or on a streetlight or other aerial lighting fixture, a utility pole, a building, and so on.

[0019] According to a further embodiment of the pre- sent disclosure, another exemplary method is provided for configuring donor and service antennas of a wireless communication node for operation in a wireless commu- nication system that includes at least one base station andat least thewireless communication node. Themeth- od may be performed by one or more processors and / or other components of the wireless communication node. According to this embodiment, the donor and service antennas are configured in a predetermined arrange- ment about a central axis.

[0020] According to this exemplary method, the donor and service antennas are rotated as a group in angular displacement increments until completing a predeter- mined angular displacement (e.g., 90 degrees, 180 de- grees, 270 degrees, 360 degrees, etc.). At each angular displacement increment, one or more wireless signals received by the donor antenna are processed to collect candidate base station data. Upon completing the pre- determined angular displacement, a base station is se- lected or discovered from the candidate base station data. A beam pattern is then formed for the donor anten- 5 10 15 20 25 30 35 40 45 50 55 6 9 EP 4 664 676 A2 10 na in a direction of the selected based station (e.g., to achieve signal strength or signal quality above a desired level for subsequent signals received from the base station). Additionally, a respective beam pattern is formed for each service antenna to provide wireless coverage to one or more service areas. Where the pre- determined angular displacement is greater than 180 degrees, rotation of the donor and service antennas as a group may be limited to no greater than 180 degrees in either direction (clockwise or counterclockwise) from a starting position in order tomitigate any twisting of cables that may be connected to the antennas, an antenna module that includes the antennas, or a support structure to which the antennas are coupled.

[0021] Thus, according to this exemplary embodiment, the wireless communication node uses a more compre- hensive analysis approach to automatically configure or position the group of donor and service antennas to enable the donor antenna to establish a high quality wireless communication path with a base station. Ac- cording to this embodiment, signals received by the donor antenna over a larger angular displacement or rotation are processed before selecting a base station to which to establish a connection. Such a methodology may be very useful where the wireless communication node is installed in the system at a fixed location where a support structure for the node and utility power are al- ready available, such as at or on a streetlight or other aerial lighting fixture, a utility pole, a building, andso forth.

[0022] According to another exemplary embodiment of the present disclosure, a wireless communication node includes a plurality of antennas positioned in a predeter- mined arrangement, one ormore processors operable to process wireless signals received by the antennas and communicate one or more control signals to the anten- nas,andamemorystoringprocessor-executable instruc- tions. In accordance with the stored instructions, the processor processes at least one wireless signal re- ceived by a first antenna to produce at least one pro- cessed first antenna signal. The processor then deter- mines whether the at least one processed first antenna signal meets base station discovery criteria. The base station discovery criteria may include one or more of a base station identifier, signal strength or other signal quality criteria, channel loading criteria, and bandwidth criteria.

[0023] When the at least one processed first antenna signal meets base station discovery criteria, the proces- sor designates the first antenna as a donor antenna, where the donor antenna is operable to communicate subsequent wireless signals with a base station that transmittedawireless signal receivedby the first antenna (e.g., a base station discovered by the wireless commu- nication node). In addition, the processor designates some or all of the remaining antennas as one or more service antennaswhen the first antenna is designated as the donor antenna.When the at least one processed first antenna signal does not meet the base station discovery criteria, the processor processes at least one wireless signal received by a second antenna to produce at least one processed second antenna signal and designates the second antenna as the donor antenna when a pro- cessed second antenna signal meets the base station discovery criteria. In such a case, the processor may further designate the other remaining antennas, includ- ing the first antenna, as one or more service antennas. Each service antenna is operable to communicate wire- less signals in one or more service or coverage areas (e.g., transmit signals to and receive signals frommobile devices, tablet computes, wireless routers, or other user equipment located in the service coverage area or areas).

[0024] After designating an antenna as the donor an- tenna, the processor may provide one or more beam control signals to the donor antenna to cause the donor antenna to form a beam pattern in a direction of the base station. Such beam control signals may also cause the donor antenna to form a beampattern to achieve a signal strength above a threshold for subsequent signals re- ceived from the base station. Additionally, the processor may provide one or more beam control signals to each service antenna to cause the service antenna to form a respective beam pattern to provide wireless coverage to one or more service areas (e.g., a respective service area). According to another exemplary embodiment, the beam pattern of the donor antenna has a higher gain and a narrower beamwidth than a gain and a beamwidth of a beam pattern of a service antenna.

[0025] According to a further exemplary embodiment of the present disclosure, the antennas include a total of four antennas, and each antenna is configured substan- tially orthogonal to a neighboring antenna so as to gen- erally form a rectangular arrangement. Alternatively or additionally, the antennas may be contained in an anten- na module, which includes a light pipe that directs am- bient light to a photo sensor. In such a case or in other embodiments, the wireless communication nodemay be constructed to bemountable to a streetlight. Thewireless communication nodemaybe a repeater in a radio access network, a relaynode ina radioaccessnetwork, or an IAB node in an IAB network. In another exemplary embodi- ment, the wireless communication node may include three antennas in total, with each antenna being config- ured approximately 120-degrees from its neighboring antenna to form a generally triangular arrangement. In other embodiments, two antennas or five or more anten- nas may be used depending on the quantities and geo- graphies of the coverage areas to be serviced by the service antennas.

[0026] According to yet another exemplary embodi- ment of the present disclosure, a wireless communica- tion node includes a plurality of antennas positioned in a predetermined arrangement, one or more processors operable to process wireless signals received by the antennas and communicate one or more control signals to the antennas, and amemory storing processor-execu- 5 10 15 20 25 30 35 40 45 50 55 7 11 EP 4 664 676 A2 12 table instructions. In accordance with the stored instruc- tions, the processor processes at least one wireless signal received by a first antenna to collect first candidate base station data and processes at least one wireless signal received by a second antenna to collect second candidate base station data. The processor selects a base station to which to communicate based on the first candidate base station data and the second candidate base station data.When the base station is selected from the first candidate base station data, the processor des- ignates the first antenna as a donor antenna operable to communicate subsequent wireless signals with the base station. The processor also designates remaining anten- nas as one ormore service antennas. On the other hand, when the base station is selected from the second can- didate base station data, the processor designates the second antenna as the donor antenna and may desig- nate the remaining antennas, including the first antenna, as one or more service antennas. Designation or selec- tion of the donor antenna may be based on whether the candidate base station data meets base station discov- ery criteria, such as one or more of a base station identi- fier, signal strength or other signal quality criteria, chan- nel loading criteria, and bandwidth criteria.

[0027] After designating the donor antenna, the pro- cessor may provide beam control signals to the donor antenna to cause the donor antenna to form a desired beam pattern in a direction of the base station. Addition- ally, the processor may provide beam control signals to each service antenna to cause the service antenna to form a desired beam pattern directed to a respective service area of one or more service areas.

[0028] According to another embodiment of the pre- sent disclosure, the wireless communication node has a total of four antennas, wherein each of the antennas is configured substantially orthogonal to a neighboring one of the antennas in a generally rectangular arrangement. Alternatively or additionally, the antennas may be con- tained in an antenna module, which includes a light pipe that directs ambient light to a photo sensor.

[0029] According to a further exemplary embodiment of the present disclosure, a wireless communication node includes four antennas, one or more processors operable to process wireless signals received by the antennas and communicate one or more control signals to the antennas, and amemory storing processor-execu- table instructions.Eachof the four antennas is configured substantially orthogonal to a neighboring one of the antennas. In accordance with the stored instructions, the processor processes at least one wireless signal received by a first antenna to produce at least one pro- cessed first antenna signal. The processor determines whether the at least one processed first antenna signal meets base station discovery criteria. If so, the processor designates the first antenna asadonor antennaoperable to communicate subsequent wireless signals with a base station that transmitted a wireless signal received by the first antenna (i.e., a base station discovered by the wire- less communication node). The processor also desig- nates the three remaining antennas as service antennas.

[0030] When at least one processed first antenna sig- nal does not meet the base station discovery criteria, the processor processes at least one wireless signal re- ceived by a second antenna to produce at least one processed second antenna signal and designates the second antenna as the donor antenna when the at least one processed second antenna signal meets the base station discovery criteria. When the second antenna is the donor antenna, the processor designates the other three remaining antennas, including the first antenna, as the service antennas.

[0031] According to yet another embodiment of the present disclosure, an exemplary method is provided for configuring antennas of a wireless communication node for operation in a wireless communication system that includes at least one base station and the wireless communication node.

DETAILED DESCRIPTION

[0037] In the following description, certain specific de- tails are set forth to provide a thorough understanding of various disclosed embodiments. However, one skilled in the relevant art will recognize that embodiments may be practiced without one ormore of these specific details, or with other methods, components, materials, etc. Also in these instances, well-known structures have been omittedor shownanddescribed in reduceddetail to avoid unnecessarily obscuring descriptions of the embodi- ments.

[0038] Referring to FIGs. 1 and 2, a wireless commu- nication node 200 is illustrated in block diagram and streetlight-mounted form, inaccordancewithoneexemp- lary embodiment of the present disclosure. The exemp- lary wireless communication node 200 includes a set or group of two or more antennas 101‑104 (four shown for illustration purposes only) oriented in different directions, one or more processors 107 (one shown for illustration purposes only), and a memory 109. The wireless com- munication node 200 may be a repeater, a relay node, or a small cell node in a radio access network (RAN) or an Integrated Access and Backhaul (IAB) node in an IAB network.

[0039] In the exemplary embodiment illustrated in FIG. 1, the antennas 101‑104 are fixedly positioned and im- movable individually or as a group. Where the set of antennas 101‑104 includes four antennas 101‑104, each antenna 101‑104 may be configured substantially ortho- gonal to a neighboring antenna 101‑104, such as illu- strated in FIG. 1. Positioning each antenna 101‑104 substantially orthogonal to each neighboring antenna 101‑104 helps provide isolation between the antennas 101‑104 during operation. In other embodiments, such as the embodiment discussed below with respect to FIGs. 4‑9, the antennas 101‑104 may be rotatable as a group about a central axis (e.g., axis 606 in FIG. 6).

[0040] In FIG. 1, the antennas 101‑104 of the exemp- lary wireless communication node 200 are illustrated as being generally coplanar. However, in alternative embo- diments, the antennas 101‑104 may be positioned in different planes (e.g., different parallel planes) relative to one another, such as in a stacked arrangement, an 5 10 15 20 25 30 35 40 45 50 55 9 15 EP 4 664 676 A2 16 offset stacked arrangement, or other multiplanar config- urations.

[0041] The memory 109 stores instructions that are executable by the processor 107 during operation of the wireless communication node 200. The instructions may be implemented as firmware, software, or any set of data that is executable or usable by the processor 107 to cause the processor 107 to perform various routines, algorithms, processes, or methods. The memory 109 may be used for other purposes too, including storing reported data from sensors within or attached to the wireless communication node 200, storing additional instructions to cause the processor 107 to perform arti- ficial intelligence or other functions, and for other pur- poses. The processor 107 may be any known processor and, in some embodiments, may be field programmable. Where the processor 107 is field programable, the pro- cessor 107 may be implemented as or include a field programmable gate array.

[0042] As very generally illustrated in FIG. 1 and de- scribed in more detail below, the processor 107 inter- faces with the set of antennas 101‑104 to receive and process wireless signals received by the antennas 101‑104 and to provide beam control signals to the antennas 101‑104, when the antennas 101‑104 are con- structed so as to be capable of receiving and responding to such control signals. For example,where theantennas 101‑104 are constructed to facilitate electronic beam formation (e.g., beamforming, beam steering, or spatial filtering), such as where the antennas 101‑104 are elec- tronically controllable phased array antennas, the anten- nas 101‑104 may be controllable by the processor 107.

[0043] One of ordinary skill in the art will readily recog- nize and appreciate that the block diagramof FIG. 1 does not depict various components that may be included in a particular wireless communication node 200, including, but not limited to, a power supply, one or more wireless transceivers, filters, a high precision clock, and various other components and modules that may be included in 5G wireless communication equipment. Such compo- nents have been omitted from the drawings to minimize complexity and facilitate a better understanding of the subject matter of the present disclosure.

[0044] To protect the antennas 101‑104 from weather and other environmental effects, the antennas 101‑104 may form part of an antenna module 105, which may include a housing 201 and / or a support structure. Where the wireless communication node 200 also performs functions based on an amount of ambient light that is detected, such as providing control of a streetlight lumi- naire 206 or other aerial lighting fixture to or for which the wireless communication node 200 is mounted, attached or configured to control, the wireless communication node 200 may include a photo sensor 130. In some embodiments, the photo sensor 130 may be positioned in theantennamodule105oranother electronic deviceor module 202 of the wireless communication node 200 to which the antenna module 105 is attached. The electro- nic module 202 may be a small cell node or a multi- function device that includes, for example, small cell functionality, light control functionality, power metering, tilt and / or vibration sensing, image capture functionality, and / or general Internet of Things (IoT) functionality. Where the wireless communication node 200 includes an antennamodule 105 and / or an electronic module 202 to which the antenna module 105 is attached, the wire- less communication node 200 or its antennamodule 105 (e.g., as part of the antenna module’s support structure) may further include a light pipe 120 for directing ambient light to the wireless communication node’s photo sensor 130. In the case where the photo sensor 130 is included within the electronic module 202 to which the antenna module 105 is attached and the electronic module 202 and its photo sensor 130 are positioned below (or above, depending on installation configuration) the antenna module 105, the light pipe 120 may be routed through the antenna module housing 201 or through an antenna module support structure, such as a post configured between the antenna module housing 201 and an aper- ture in the electronic module 202 aligned with the photo sensor 130.

[0045] As illustrated in FIG. 2, the wireless communi- cation node 200 may be mountable to a streetlight or other fixture exposed to ambient light. In the case where the wireless communication node 200 is mounted to a streetlight, the wireless communication node’s photo sensor 130 may be used as part of a system for control- ling operation of the streetlight. In FIG. 1, the light pipe 120 and the photo sensor 130 are shown disposed linearly along a central, vertical axis of the antenna module 105 or its support structure. However, one skilled in theartwill readily appreciate that the light pipe120may be routed in anymanner to direct ambient light to a photo sensor 130 positioned below the antenna module 105 or at another location. In a further embodiment, the photo sensor 120 may be included in the antenna module 105 instead of in an electronic module 202 to which the antenna module 105 is attached.

[0046] Referring again to FIG. 2, the wireless commu- nication node 200 may be streetlight-mountable through use of an electric socket integrated into the top of a streetlight luminaire 206. To secure the wireless commu- nication node 200 to the streetlight with adequate strength to withstand wind load and other various envir- onmental conditions, the wireless communication node 200, or a portion of it (e.g., the electronic module 202), may be secured to the streetlight pole 208 through use of a mounting bracket 204.

[0047] FIG. 3 illustrates a logic flow diagram 300 of steps performed to select a donor antenna and one or more service antennas from the set of antennas 101‑104 included as part of the exemplary wireless communica- tion node 200. The logic flow steps of FIG. 3 may be performed by the one or more processors 107 of the wireless communication node 200 through execution of instructions stored in the node’s memory 109. 5 10 15 20 25 30 35 40 45 50 55 10 17 EP 4 664 676 A2 18

[0048] According to the logic flow of FIG. 3, the pro- cessor 107 processes (301) at least one wireless signal received by a first one of the antennas 101‑104. The first antenna may be any one of the antennas 101‑104 from which the donor and service antennas will be selected. The processor 107 determines (303) whether any wire- less signal received by the first antenna meets base station discovery criteria. Such criteria may include, among other things, whether the signal includes an identifier for a base station (e.g., a gNB identifier), whether a signal strength or other signal quality metric for the received signalmeets a desired strength or quality level, whether channel loading for the base station is determined to be less than a maximum threshold based on data or information in the signal, and / or whether frequencies and bandwidths supported by the base sta- tion are within a desired frequency range with minimum bandwidth thresholds.

[0049] In some embodiments, multiple wireless sig- nals may be detected from the first antenna (e.g., anten- na 101) or any subsequently evaluated antenna (e.g., antennas 102‑104). For example, as part of the evalua- tion of the first antenna, the processor 107 may send control signals to the antenna 101 to form a beampattern having predetermined or intelligently-selected beam width or conical field of view (e.g., a 15-degree conical field of view). The processor 107 may then send control signals to the antenna 101 to electronically steer the beam pattern across its entire azimuth range seeking to receive any base station signals. Where the wireless communication node 200 includes four antennas 101‑104 configured as illustrated in FIG. 1, the azimuth range of each antenna 101‑104 encompasses about 90 degreesof theentire azimuth rangeof the set of antennas 101‑104 (e.g., 360 degrees). In such cases, each wire- less signal received by the antenna under evaluation 101‑104 may be processed to determine whether the signal meets the base station discovery criteria.

[0050] When the processor 107 determines (303) that a wireless signal received from the first antenna (e.g., antenna 101) meets base station discovery criteria, the processor 107 designates (305) the antenna 101 as the donor antenna for the wireless communication node 200 and forms (305) a beam pattern for the donor antenna 101 in a direction of the wireless signal or from which the wireless signal was received, which also has a high probability of being the direction of the discovered base station. To form the donor antenna’s beam pattern, the processor 107 may provide one or more beam control signals to the donor antenna 101 (e.g., to antenna ele- ments of the antenna’s phased array) to cause the beam pattern to have a desired gain, beam width, and / or con- ical field of view, or to achieve a signal strength above a threshold for subsequent signals received from the base station. After or contemporaneous with designating the donor antenna 101, the processor 107 designates (307) some or all of the remaining antennas (e.g., antennas 102‑104) as service antennas and forms (307) beam patterns for one or more of those antennas 102‑104 so as to provide wireless coverage to one or more service areas. To form the beam patterns for the service anten- nas102‑104, theprocessor 107mayprovideoneormore beam control signals to each service antenna 102‑104 (e.g., to antennaelementsof theantenna’sphasedarray) to cause the service antenna 102‑104 to form a respec- tive beampattern to providewireless coverage to the one or more service areas.

[0051] When the processor 107 determines (303) that awireless signal received from thefirst antenna101does not meet the base station discovery criteria, or that no wireless signal received from the first antenna 101meets the base station discovery criteria (e.g., where wireless signals are received from the first antenna 101 for a preset or variable period of time), the processor 107 determines (309) whether all the antennas 101‑104 of the wireless communication node 200 have been pro- cessed. If all the antennas 101‑104 have not yet been processed, then the processor 107 processes (301) one ormorewireless signals received fromanother oneof the antennas 102‑104 and the signal analysis process re- peats until either the antennas 101‑104 have been de- signated as donor and service antennas and their beam patterns have been formed or no wireless signal has been received that meets the base station discovery criteria. If the latter condition occurs, the instructions stored in the memory 109 may cause the processor 107 to wait a predetermined period of time (e.g., 30 seconds to 5 minutes) and then repeat the logic flow of FIG. 3.

[0052] Where the wireless communication node 200 includes four fixed antennas 101‑104 as generally illu- strated in FIG. 1, the beam pattern of each antenna 101‑104may be formed to serve its determined purpose. For example, the beamsof the service antennas102‑104 may be formed to cover one or more desired or selected service areas; whereas, the beam pattern for the donor antenna 101 may be formed to achieve maximum signal strength for signals received from the discovered base station. Beam formation for each antenna 101‑104 may depend upon various factors, including the antenna’s center frequency and bandwidth, use case, and quantity of phased antenna array elements. As one example, where three service antennas 102‑104 are intended to cover a 270-degree azimuth after determination of the donor antenna 101, the beam pattern for each service antenna 102‑104may be formed to have a beamwidth of about 60degreesandbeelectronically steerable to cover about a 120-degree conical field of view in the azimuth.

[0053] According to yet another exemplary embodi- ment of the present disclosure, the processor 107 may process at least one wireless signal received by a first antenna (e.g., antenna 101) to collect first candidate base station data and processes at least one wireless signal received by a second antenna (e.g., antenna 102, antenna 103, or antenna 104)) to collect second candi- date base station data. The processor 107 then selects a 5 10 15 20 25 30 35 40 45 50 55 11 19 EP 4 664 676 A2 20 base station to which to communicate based on the first candidate base station data and the second candidate base station data.When the base station is selected from the first candidate base station data, the processor 107 designates the first antenna (e.g., antenna 101) as a donor antenna operable to communicate subsequent wireless signals with the base station. The processor 107 also designates some or all of the remaining anten- nas (e.g., antennas 102‑104) as one or more service antennas. On the other hand, when the base station is selected from the second candidate base station data, the processor 107 designates the second antenna (e.g., antenna 102, antenna 103, or antenna 104, as applic- able) as the donor antenna and may designate some or all of the remainingantennas (e.g., antenna101, antenna 102, and antenna 104 where antenna 103 was selected as the donor antenna), including the first antenna, as one ormore service antennas. Designation or selection of the donor antenna may be based on whether the candidate base station data meets base station discovery criteria, such as one or more of a base station identifier, signal strength or other signal quality criteria, channel loading criteria, and bandwidth criteria. After designating the donor antenna, the processor 107 may provide beam control signals to the donor antenna to cause the donor antenna to form a desired beam pattern in a direction of the base station. Additionally, the processor 107 may provide beam control signals to each service antenna to cause the service antenna to form a desired beam pattern directed to one or more service areas. Determi- nation of which antenna 101‑104 of the donor antenna may be based on whether the candidate base station data meets base station discovery criteria.

[0054] Alternatively, the processor 107 may process wireless signals received by all the antennas 101‑104 on an antenna-by-antenna basis to collect candidate base station data. The processor 107 may then select or designate a base station to which to communicate based on the candidate base station data and designate the antenna that received the wireless signal or signals from the selected base station as the donor antenna. The processor 107 may also designate the remaining anten- nas as service antennas, although not all of the service antennas may be used. Designation or selection of the donor antennamaybebased onwhether candidate base station data meets base station discovery criteria. After the donor and service antennas have been designated, the processor may send beam control signals to the antennas 101‑104 to form a desired beam pattern in a direction of the selected base station (for the donor antenna) or form desired beam patterns directed to a one or more service areas (for the service antennas).

[0055] Referring to FIGs. 4‑7, an alternative wireless communication node 400 is illustrated in block diagram and other forms, in accordance with another exemplary embodiment of the present disclosure. The alternative, exemplary wireless communication node 400 includes a set or group of two or more antennas 401‑404 (four shown for illustration purposes only) oriented in different directions, one or more processors 407 (one shown for illustration purposes only), an actuator 408, and a mem- ory 409. The actuator 418 may be a servo, stepper, induction or other type ofmotor that can provide sufficient torque to rotate the antennas 401‑404 as a group (e.g., rotate a support structure to which the antennas 401‑404 are coupled) selected angular displacement amounts. The wireless communication node 400 may be a repea- ter, a relay node, or a small cell node in a radio access network (such as, for example, a time division duplex (TDD) or frequency division duplex (FDD) 5Gnetwork) or an IAB node in an IAB network.

[0056] In the exemplary embodiment illustrated in FIGs. 4‑7, the antennas 401‑404 are rotatable as a group about a central axis 606 by the actuator 408. Where the set of antennas includes four antennas 401‑404, each antenna 401‑404 may be configured substantially ortho- gonal to a neighboring antenna 401‑404, such as illu- strated in FIGs. 4 and 5. Positioning each antenna 401‑404 substantially orthogonal to each neighboring antenna 401‑404 helps provide isolation and mitigates crosstalk between the antennas 401‑404 during opera- tion.

[0057] The antennas 401‑404 of the exemplary wire- less communication node 400 are illustrated as being generally coplanar. However, in alternative embodi- ments, the antennas 401‑404 may be positioned in dif- ferent planes (e.g., different parallel planes) relative to one another, such as in a stacked arrangement, an offset stacked arrangement, or other multiplanar configura- tions.

[0058] The memory 409 stores instructions that are executable by the processor 407 during operation of the wireless communication node 400. The instructions may be implemented as firmware, software, or any set of data that is executable by the processor 407 to cause the processor 407 to perform various routines, algorithms, processes, or methods. The memory 409 may be used for other purposes too, including storing data reported from sensors within or attached to the wireless commu- nication node 400, storing additional instructions to cause the processor 407 to perform artificial intelligence or other functions, and for other purposes. The processor 407 may be any known processor or processors and, in some embodiments, may be field programmable.Where the processor 407 is field programmable, the processor 407 may be implemented as or include a field program- mable gate array.

[0059] As very generally illustrated in FIG. 4 and de- scribed in more detail below, the processor 407 inter- faces with the donor and service antennas 401‑404 to receive and process wireless signals received by the antennas 401‑404 and to provide beam control signals to the antennas 401‑404, when the antennas 401‑404 are constructed so as to be capable of receiving and responding to such control signals. For example, where the antennas 401‑404 are constructed to facilitate elec- 5 10 15 20 25 30 35 40 45 50 55 12 21 EP 4 664 676 A2 22 tronic beam formation (e.g., beamforming, beam steer- ing, or spatial filtering), such as where the antennas 401‑404 are electronically controllable phased array an- tennas, the antennas 401‑404may be controllable by the processor 407.

[0060] One of ordinary skill in the art will readily recog- nize that the block diagram of FIG. 4 does not depict various components that may be included in a particular wireless communication node 400, including, but not limited to, a power supply, one or more wireless trans- ceivers, filters, a high precision clock, and various other components and modules that are conventional to 5G wireless communication equipment. Such components have been omitted from the drawings to minimize com- plexity and to facilitate a better understanding of the subject matter of the present disclosure.

[0061] To protect the antennas 401‑404 from weather and other environmental effects, the antennas 401‑404 may form part of an antenna module 405, which may include a housing 616 and / or a support structure. When included, the support structure may be or include a plat- form 428, a post 418, a combination thereof, or any other elements or components that may support the antennas 401‑404 and facilitate their rotation as a group. For ex- ample, the support structuremaybeor includeapost 418 or other structure or structures to which the antennas 401‑404 may be coupled to facilitate their rotation as a group by the actuator 408. The antennamodule 405 or its support structure or a portion thereof (e.g., the post 418) maydefine a central axis 606 for the antennamodule 405 aboutwhich the donor and service antennas 401‑404 are configured in a predetermined arrangement (e.g., ortho- gonal to their neighboring antennas when a total of four antennas 401‑404 are used).

[0062] Where the wireless communication node 400 also performs functions based on an amount of ambient light that is detected, such as providing control of a streetlight luminaire 206 or other aerial lighting fixture to of for which the wireless communication node 400 is mounted, attached or configured to control, the wireless communication node 400 may include a photo sensor 430. In someembodiments, thephoto sensor430maybe positioned in the antennamodule 405 or another electro- nic device or module 440 of the wireless communication node 400 to which the antenna module 405 is attached. The electronic module 440 may be a small cell node or a multi-function device that includes, for example, small cell functionality, light control functionality, power meter- ing, tilt and / or vibration sensing, image capture function- ality, and / or general Internet of Things (IoT) functionality. Where thewireless communicationnode400 includesan antenna module 405 and / or an electronic module 440 to which the antenna module 405 is attached, the wireless communication node 400 or its antennamodule 405may further include a light pipe 420 for directing ambient light to the wireless communication node’s photo sensor 430. In the casewhere the photo sensor 430 is includedwithin the electronic module 440 to which the antenna module 405 is attached and the electronic module 440 and its photo sensor 430 are positioned below (or above, de- pending on installation configuration) the antenna mod- ule 405, the light pipe 420 may be routed through the antenna module housing 616 or through an antenna module support structure, such as a post 418 configured between the antenna module housing 616 and an aper- ture in the electronic module 440 aligned with the photo sensor 430.

[0063] As illustrated in FIG. 6, the wireless communi- cation node 400 may be mountable to a streetlight or other fixture exposed to ambient light. In the case where the wireless communication node 400 is mounted to a streetlight, the wireless communication node’s photo sensor 430 may be used as part of a system for control- ling operation of the streetlight. In FIGs. 4 and 5, the light pipe 420 and the photo sensor 430 are shown disposed linearly along a central, vertical axis of the antenna module 105, such as along an axis defined by a post 418 of a support structure. However, one skilled in the art will readily appreciate that the light pipe 420 may be routed in any manner to direct ambient light to a photo sensor 430 positioned below the antenna module 405 or at another location. In a further embodiment, the photo sensor 420 may be included in the antenna module 405 instead of in an electronic module 440 to which the antenna module 405 is attached.

[0064] As illustrated in FIG. 6, the wireless communi- cation node 400 may be streetlight-mountable through use of an electric socket integrated into the top of the streetlight luminaire 206. To secure the wireless commu- nication node 400 to the streetlight with adequate strength to withstand wind load and other various envir- onmental conditions, the wireless communication node 400, or a portion of it (e.g., the electronic module 440), may be secured to the streetlight pole 208 through use of a mounting bracket 204.

[0065] FIG. 7 illustrates exemplary antenna implemen- tation and beam pattern formation embodiments for var- ious antennas 401‑404 of the wireless communication node 400 of FIG. 4, in accordance with further exemplary embodiments of the present disclosure. The antenna implementation and beam pattern formation embodi- ments illustrated in FIG. 7 may also be used for imple- menting and forming beam patterns for the antennas 101‑104 of the wireless communication node 200 de- scribed above with respect to FIGs. 1 and 2.

[0066] In someembodiments, oneormoreof thedonor and service antennas 101‑104, 401‑404 may be imple- mentedor includeaphasedantennaarray611containing an array of antenna elements 612. For example, as illustrated in FIG. 7, a phased antenna array module 611 may be part of the donor antenna 401 or any other antenna 101‑104, 402‑404 and include an array of an- tenna elements 612 configured on a substrate. The an- tennaelements612of thephasedantennaarray611may be coupled to a local controller board 620, which may form one of the processors 407, to enable the controller 5 10 15 20 25 30 35 40 45 50 55 13 23 EP 4 664 676 A2 24 board620 to formand re-from (e.g., steer) abeampattern 601 for the applicable antenna 101‑104, 401‑404 (e.g., the donor antenna 401 in this example). According to some embodiments, the donor antenna 401 has a higher gain andanarrower beamwidth than thegains andbeam widths of the service antennas 402‑404. In theexemplary embodiment illustrated in FIG. 7, the donor antenna 401 has a high gain, narrow bandwidth (e.g., in the 5-degree to 20-degree conical field range) beam pattern directed toward a discovered base station 610. During the beam formation process performed upon discovery of a base station, one ormore of the processors 407 (e.g., the local controller 620) provides beam control signals to the antennas 401‑404 to form the beam patterns for the antennas 401‑404 (e.g., pattern 601 for the donor anten- na 401, pattern 602 for one service antenna 402, and pattern 604 for another serviceantenna404). It shouldbe noted, as illustrated in FIG. 7, one or more of the service antennas 402‑404may not be used after discovery of the base station 610 because service coverage may not be needed in the coverage area or areas of such antenna or antennas. The stored instructions in the wireless com- municationnode’smemory409maycause theprocessor 407 to use only some of the service antennas 402‑404 after discovery of the base station 610 depending on the locations of the service areas to be supported by the service antennas 402‑404.

[0067] FIG. 8 illustrates a logic flow diagram 800 of steps performed to configure the donor and service an- tennas 401‑404 of the alternative, exemplary wireless communication node 400, in accordance with further exemplary embodiments of the present disclosure. The logic flow steps of FIG. 8 may be performed by one or more processors 407 of the wireless communication node 400 through execution of instructions stored in the node’s memory 409.

[0068] According to the logic flow of FIG. 8, the pro- cessor 407 processes (801) at least one wireless signal received by the donor antenna 401 and determines (803) whether the wireless signal received by the donor anten- na 401 meets base station discovery criteria. As dis- cussed above, such criteria may include, among other things, whether the signal includes an identifier (e.g., a gNB identifier) for a base station, whether a signal strength or other signal quality metric for the received signal meets a desired strength or quality level, whether channel loading for the base station is determined to be less than a maximum threshold based on data or infor- mation in the signal, and / or whether frequencies and bandwidths supported by the base station are within a desired frequency range with minimum bandwidth thresholds.

[0069] When the processed signal does not meet the base station discovery criteria, the processor 407 rotates (805) thedonor andserviceantennas401‑404asagroup about a central axis 606 by an angular displacement. The angular displacementmay be any desired displacement. Inoneexemplaryembodiment, theangular displacement is in a range of five to fifteen degrees in a particular direction (e.g., clockwise or counterclockwise). The pro- cessor 407 may perform the rotation by providing one or more control signals to an actuator 408 configured to turn a support structure to which the antennas 401‑404 are coupled.

[0070] After the antennas 401‑404 have been rotated by the angular displacement, the processor processes (801) another signal received by the donor antenna 401 while oriented in its new direction and determines (803) whether the received signal meets the base station dis- covery criteria. When this received signal does not meet the base station discovery criteria, the rotate andprocess routine continues until a wireless signal received by the donor antenna 401 meets the base station discovery criteria. The angular displacement during each rotation phase of the antenna configuration process may be the sameor different than theprevious angular displacement depending on the algorithm or method selected for base station discovery. For example, where a coarse / fine tun- ing discovery approach is implemented, the angular dis- placement of the group of antennas 401‑404 may be larger earlier in the process and then get progressively smaller.

[0071] Once a wireless signal received by the donor antenna 401 meets the base station discovery criteria, the processor forms (807) a beam pattern for the donor antenna 401 in a direction fromwhich the wireless signal meeting the base station discovery criteria was received (e.g., in adirectionof thediscoveredbasestation610 that transmitted the wireless signal). The processor 407 may form the donor antenna’s beam pattern by providing one or more beam control signals to the donor antenna 401 (e.g., to the donor antenna’s antenna elements 612) to cause the donor antenna 401 to form a beam pattern to achieve a signal strength above a threshold for subse- quent signals received from the discovered base station 610.

[0072] The processor 407 also forms (809) beam pat- terns for the service antennas 402‑404 to provide wire- less coverage to one or more service areas. The beam patterns for the service antennas 402‑404 may have substantially less gain and wider conical fields of view than the gain and conical field of view of the donor antenna 401. The processor 407 may form each service antenna’s beam pattern by providing one or more beam control signals to the respective serviceantenna402‑404 (e.g., to the service antenna’s antenna elements 612) to cause the service antenna 402‑404 to form a beam pattern having a desired gain and conical field of view.

[0073] FIG. 9 illustrates an alternative logic flow dia- gram 900 of steps performed to configure the donor and serviceantennas401‑404of thewireless communication node 400 of FIG. 4, in accordance with additional ex- emplary embodiments of the present disclosure. The logic flow steps of FIG. 9 may be performed by one or more processors 407 of the wireless communication node 400 through execution of instructions stored in 5 10 15 20 25 30 35 40 45 50 55 14 25 EP 4 664 676 A2 26 the node’s memory 409.

[0074] According to the logic flow of FIG. 9, the pro- cessor 407 processes (901) at least one wireless signal received by the donor antenna 401 and collects (903) candidate base station data from the signal. The candi- date base station data may be any data necessary to determine (a)adirection fromwhichawirelesssignalwas received by the donor antenna 401 relative to a starting position for the group of antennas 401‑404 and (b) whether the wireless signal meets the base station dis- covery criteria.

[0075] The processor 407 then determines (905) whether the group of antennas 401‑404 have completed a predetermined rotation or angular displacement.When the group of antennas 401‑404 has not completed the predetermined angular displacement, the processor 407 rotates (907) the antennas 401‑404 as a group by an angular displacement increment, which may be deter- mined based on various factors, including installation location of the wireless communication node 400, use case, quantity and locations of possible signal obstruc- tions, and so forth. In one exemplary embodiment, the angular displacement increment is in a range of five to fifteen degrees in a particular direction (e.g., clockwise or counterclockwise). The processor 407 may perform the rotation by providing one or more control signals to an actuator 408 configured to turn a support structure to which the antennas 401‑404 are coupled.

[0076] After the antennas 401‑404 have been rotated as a group by the angular displacement increment, the processor 407 processes (901) wireless signals, if any, received by the donor antenna 401 and collects (903) additional candidate base station data, if any, from the signal(s). The processor 407 then determines whether the group of antennas 401‑404 have completed the pre- determined rotation. If not, the rotation, processing, and collection functions of logic flowblocks 907, 901, and 903 continue until the antennas 401‑404 have been rotated as a group by the predetermined angular displacement (e.g., 90 degrees, 180 degrees, 270 degrees, 360 de- grees, or some other chosen displacement amount). Where the predetermined angular displacement is great- er than 180 degrees, the processor 407may send control signals to the actuator 408 so as to rotate the donor and serviceantennas401‑404asagroupnogreater than180 degrees in either direction (clockwise or counterclock- wise) from a starting position in order to mitigate any twisting of cables that may be connected to the antennas 401‑404, an antenna module 405 that includes the an- tennas 401‑404, or a support structure to which the antennas 401‑404 are coupled.

[0077] After the antennas 401‑404 have been rotated as a group by the predetermined angular displacement, the processor 407 selects (909) a base station based on the collected candidate base stationdata and forms (911) a beam pattern for the donor antenna 401 in the direction of the selected base station (e.g., in the direction from which the wireless signal from the selected base station was received during the candidate base station data collection process). The processor 407 may form the donor antenna’s beam pattern by providing one or more beam control signals to the donor antenna 401 (e.g., to the donor antenna’s antenna elements 612) to cause the donor antenna 401 to form a beam pattern to achieve a signal strength above a threshold for subsequent signals received from the selected base station.

[0078] The processor 407 also forms (913) beam pat- terns for the service antennas 402‑404 to provide wire- less coverage to one or more service areas. The beam patterns for the service antennas 402‑404 may have substantially less gain and wider conical fields of view than the gain and conical field of view of the donor antenna 401. The processor 407 may form each service antenna’s beam pattern by providing one or more beam control signals to the respective serviceantenna402‑404 (e.g., to the service antenna’s antenna elements 612) to cause the service antenna 402‑404 to form a beam pattern having a desired gain and conical field of view.

[0079] In some embodiments, the wireless communi- cation node 200, 400 can further include at least one or more processors (not shown) mounted on a substrate that can further include a communication module or transceiver that enables wireless communication of data and control signals over one or any number of known wireless protocols (LTE, 5G, Wi-Fi, etc.).

[0080] The wireless communication node 200, 400 may provide wireless communication capability to any one or more devices having corresponding wireless transceivers. In somecases, for example, using function- ality provided by the wireless communication node 200, 400, the electronic components embedded in a wireless communication node 200, 400 are arranged to operate as a Wi-Fi access point. In this way, the electronic com- ponents permit one ormoremobile devices to access the Internet. Municipalities or other entities may make Inter- net services available over a determined geographic area (e.g., a neighborhood, a city, an arena, a construc- tion site, a campus, or the like) to remote mobile devices that are in proximity to any one of a plurality of wireless communication nodes 200, 400. For example, if many streetlight fixtures in a neighborhood or city are equipped with awireless communicationdevice, suchasawireless communication node 200, 400, thenWi-Fi service can be provided to a large number of users. Further, based on seamless communication between a plurality of wireless communication device embodiments, the Wi-Fi service can be configured as a mesh that permits users to per- ceive constant internet connectivity even when the mo- bile device is in motion.

[0081] In some embodiments, the wireless communi- cationnode200,400maymonitor oneormoresensorsor conditions associated with a corresponding streetlight fixture for events. Examples of events can include, but are not limited to, light source failure (e.g., a burned out bulb), light pole tilt, external vibrations, light source tem- perature, external temperature, power usage, captures 5 10 15 20 25 30 35 40 45 50 55 15 27 EP 4 664 676 A2 28 of images,motion detection, sound recordings, vehicular or pedestrian traffic, ambient light level, or other informa- tion that can be obtained or recorded by the wireless communication node 200, 400.

[0082] Thewireless communicationnode200, 400can be part of a system or network of streetlight poles, street- light fixtures, streetlight sources, or the like in a system level deployment controlled by a municipality or other government agency. In other cases, the system may be controlledbyaprivateentity (e.g., privateproperty owner, third-party service contractor, or the like). In still other cases, a plurality of entities may share control of the system of streetlight poles streetlight fixtures, streetlight sources, or the like.

[0083] In other embodiments, each wireless commu- nication node 200, 400 may be equipped with commu- nication capabilities, which allows for the monitoring or remote control of a light source of the streetlight fixture or of another utility device. Accordingly, each light source in each streetlight fixture or in a broader context each device in any fixture can be monitored and controlled remotely independently or in combination. In thecaseofa streetlight fixture, each streetlight fixture can be moni- tored and / or controlled as an independent light source or in combination with other light sources where the elec- tronic apparatus can serve to provide the wireless (or wired) communication of light control signals and any other information (e.g., packetized data) between wire- less communication devices.

[0084] As one non-limiting, non-exhaustive example, each wireless communication node 200, 400 may oper- ate as a small cell node, a relay node, or a repeater to provide wireless cellular-based network communication services. A mobile device provisioned by a mobile net- work operator or carrier can communicatewith awireless communication node 200, 400 in the same or similar manner that a mobile device communicates with a macrocell tower. In at least some cases, an active com- munication session formed between a wireless commu- nication node 200, 400 and a mobile device may be handed-off to or from another wireless communication node 200, 400 as the mobile device moves into or out from the active range of the wireless communication node 200, 400. For example, a user having an active communication session enabled by a wireless commu- nication node 200, 400 may be in motion, and when the mobile device is in motion, the active communication session may in some cases be automatically and seam- lessly handed off and continue via another wireless com- munication node 200, 400 or via a macrocell tower.

[0085] Thewireless communicationnode200, 400can be integratedwith a light fixture or a light pole andmay be formed of any number of materials. The wireless com- munication node 200, 400 can be arranged as a network- ing device, but in other embodiments, the wireless com- munication device is a smart sensor device, a combina- tion device, some other wireless networking device, or some other control device. In some embodiments, the light fixture can include a light source that can be an incandescent light source, a light emitting diode (LED) light source, a high pressure sodium lamp, or any other type of light source.

[0086] Again, the wireless communication node 200, 400 is not limited to attaching to a streetlight, but can attach to any number of objects including, but not limited to a light pole, an LED board, a bracket, a street sign, a highway sign, a bus stop shelter, an automated teller machine (ATM), a phone booth, a building, anHVACunit, amailbox, abillboard, a light, aparkingsign, a stop light, a speed limit sign, a solar cell, a crosswalk sign, a tunnel, a utility box, awater tower, acrane, a radioantenna tower, a store, an awning, a roof, or a parking pay station. In some embodiments, each of these items are identified in amap of amap service so that appropriatemodifications can be made with base station selections and beam forming of donor and service antennas.

[0087] Note that references to "substrate" or " board" hereinmay refer to acircuit board,whichmaybeaprinted circuit board ("PCB"), including, without limitation, a sin- gle sided PCB, a double sided PCB, a multilayer PCB, a rigid PCB, a flex PCB, or a hybrid rigid-flex PCB or a portion of a housing serving as a substrate. As is under- stood, any of the above circuit boards may include var- ious electronic components coupled to, or carried by the circuit boards, including, for example, integrated circuits, integrated circuit chips or dies (including, without limita- tion, semiconductor chips or dies), wires, transistors, leadframes or pads, antennas, receivers, transmitters, transceivers, or other components.Moreover, eachof the electronic components described above may be in elec- tronic communication, either via wires (e.g., to transmit power or signals, among other functionality), or wire- lessly to one ormore of the other electronic components. Further, it is to beunderstood that anyof theabovecanbe coupled to one or more of the other electronic compo- nents of the wireless communication node 200, 400 through one or more known coupling techniques or ma- terials.

[0088] Moreover, in some cases, one or more internal or external antennas may be electrically and communi- catively coupled to the wireless communication node 200, 400 and integrated into, or mounted onto, various featuresofanexternal fixturesuchasa light pole. In some instances, one or more wires may extend through a light pole to communicatively and electrically couple the wire- less communication device and the one or more anten- nas.

[0089] Further, it is to be appreciated that the present disclosure includes methods for forming a wireless com- munication node, the forming including providing the electronic components in a housing enclosure suitable to be attached to any of the objects describe herein and other like objects, installing the wireless communication device, and connecting the wireless communication de- vice to a power source or other utility line to pass power and data via one ormore wires or cables or via a wireless 5 10 15 20 25 30 35 40 45 50 55 16 29 EP 4 664 676 A2 30 communication channel.

[0090] In the absence of any specific clarification re- lated to its express use in a particular context, where the terms "substantial" or "about" in any grammatical form are used as modifiers in the present disclosure and any appended claims (e.g., to modify a structure, a dimen- sion, a measurement, or some other characteristic), it is understood that the characteristic may vary by up to 30 percent. For example, a wireless communication net- working device may be described as being mounted "substantially vertical," In these cases, a device that is mounted exactly vertical is mounted along a "Y" axis and a "X" axis that is normal (i.e., 90 degrees or at right angle) to a plane or line formed by a "Z" axis. Different from the exact precision of the term, "vertical," and the use of "substantially" or "about" to modify the characteristic permits a variance of the particular characteristic by up to 30 percent.

[0091] The term "include" and variations thereof, in all of their syntactic contexts, are to be construed without limitation in an open, inclusive sense, (e.g., "including, but not limited to"). The term "or," is inclusive, meaning and / or. The phrases "associated with" and "associated therewith," as well as derivatives thereof, can be under- stood as meaning to include, be included within, inter- connect with, contain, be contained within, connect to or with, couple to or with, be communicable with, cooperate with, interleave, juxtapose, be proximate to, be bound to or with, have, have a property of, or the like.

[0092] Unless the context requires otherwise, through- out the specification and claims which follow, the word "comprise" and variations thereof, such as, "comprises" and "comprising," are to be construed in an open, inclu- sive sense (e.g., "including, but not limited to").

[0093] Reference throughout this specification to "one embodiment" or "an embodiment" or "some embodi- ments" and variations thereof mean that a particular feature, structure, or characteristic described in connec- tion with the embodiment is included in at least one embodiment. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitablemanner in one ormore embodi- ments.

[0094] As used in this specification and the appended claims, the singular forms "a," "an," and "the" include plural referents unless the content and context clearly dictates otherwise. It should also be noted that the con- junctive terms, "and" and "or" are generally employed in the broadest sense to include "and / or" unless the content and context clearly dictates inclusivity or exclusivity, as thecasemaybe. Inaddition, thecompositionof "and"and "or" when recited herein as "and / or" is intended to en- compass an embodiment that includes all of the asso- ciated items or ideas and one or more other alternative embodiments that include fewer thanall of theassociated items or idea.

[0095] In thepresent disclosure, conjunctive listsmake use of a comma, which may be known as an Oxford comma, a Harvard comma, a serial comma, or another like term. Such lists are intended to connect words, clauses, or sentences such that the thing following the comma is also included in the list.

[0096] As the context may require in this disclosure, except as the context may dictate otherwise, the singular shall mean the plural and vice versa. All pronouns shall meanand include theperson, entity, firmor corporation to which they relate.

[0097] When so arranged as described herein, each computing device may be transformed from a generic andunspecific computing device to a combination device comprising hardware and software configured for a spe- cific and particular purpose. When so arranged as de- scribed herein, to the extent that any of the inventive concepts described herein are found by a body of com- petent adjudication to be subsumed in an abstract idea, the ordered combination of elements and limitations are expressly presented to provide a requisite inventive con- cept by transforming the abstract idea into a tangible and concrete practical application of that abstract idea.

[0098] The various embodiments describedabove can be combined to provide further embodiments. Aspects of the embodiments can be modified, if necessary to em- ploy concepts of the various patents, applications, and publications to provide further embodiments. EXAMPLE EMBODIMENTS
