Description

Communication device TECHNICAL FIELD

[0001] The present disclosure belongs to the technical field of communication, and particularly relates to a communication device. BACKGROUND

[0002] In recent years, China's new information infrastructure construction at sea is in full swing. With the advent of the 5G era, the marine economy is ushering in new opportunities for scale development. Through accelerating 5G coverage in the open sea, basic telecom enterprises will extend 5G to the sea, integrate into the construction of "smart ocean", and continuously accelerate the construction of 5G networks in the B28 (B5 / B28, etc.) frequency band. As the main frequency band promoted by major operators, N41 (B41) will become increasingly important in future near-sea deployment.

[0003] Traditional sea area communication mainly includes two types. One is satellite transmission, which requires professional equipment and is expensive, making it difficult to meet the needs of ordinary customers. The other is to rely on the 4G network already covered in coastal areas, but the coverage distance is short and cannot meet the needs of customers at sea. A relatively innovative solution is to use B28+B41 coastal base station super-coverage + ferry cabin repeater station to enhance coverage, but due to the use of omnidirectional antennas, the radiation efficiency is low, and the size is large, which is not convenient to install. At the same time, the repeater station is a relay and amplification of wireless information, and the use of terminals must have a 5G module, which has high requirements for user equipment, and in the case of many ships, it is easy to produce self-excitation, which seriously affects the Internet experience.

[0083] To continuously expand the coverage of the sea area, effectively improve the user experience in the cabin, and help build a far-reaching, high-quality 5G smart ocean network, the present disclosure provides a kind of communication equipment for realizing the communication connection between base station and terminal, its structural diagram is as shown in Figure 1.It needs to be explained, according to the direction of signal transmission, the signal transmission process between base station and terminal can be divided into uplink and downlink, specifically, uplink refers to the process that signal is transmitted from terminal to base station, and downlink refers to the process that signal is transmitted from base station to terminal.Referring to Figure 1, the communication equipment of the present disclosure includes antenna module 1, signal processing module 2 and 5G CPE module 3.In the uplink, the terminal sends the terminal signal that needs to be uploaded to the 5G CPE module 3, and the 5G CPE module 3 converts the terminal signal for transmission, and the converted terminal signal is transmitted to the signal processing module 2, which is processed and sent to the antenna module 1, for example, the terminal signal is amplified to avoid distortion and attenuation, and the signal stability is improved.After that, the antenna module 1 radiates the processed signal to the base station in the form of electromagnetic wave, and completes the transmission of the terminal signal.In the downlink, the base station signal is transmitted in the form of electromagnetic wave, and the antenna module 1 receives the base station signal and transmits it to the signal processing module 2 for processing, and then the processed signal is transmitted to the 5G CPE module 3 for conversion to facilitate terminal access.

[0084] In some examples, in the communication link in which the signal is transmitted from the terminal to the base station, i.e.in the uplink, the signal processing module 2 includes a fixed attenuator and a final amplifier.The fixed attenuator is mainly used to adjust the signal strength, balance the signal strength in the multi-signal system, and control the signal strength in the test and measurement process.The final amplifier, also known as power amplifier, is mainly used to amplify the signal in the communication link to ensure that the signal has enough strength and can be transmitted farther.

[0085] In the communication link in which the signal is transmitted from the base station to the terminal, i.e.in the downlink, the signal processing module 2 includes a low-noise amplifier and a filter.The low-noise amplifier can amplify weak signals while reducing noise in the communication link to improve signal quality and reception sensitivity.The filter can remove noise and suppress noise interference, while selecting the frequency to be passed and filtering out the unwanted signal.In some examples, in the communication link that transmits high-frequency signals, such as N41 signals (operating frequency of 2515MHz-2675MHz), the filter can use SAW surface acoustic wave filter.In the communication link that transmits low-frequency signals, such as N28 signals (operating frequency of about 700MHz), the filter can use a bandpass acoustic table filter, and the working frequency band of the bandpass acoustic table filter can be, for example, 758MHz-788MHz.

[0086] In some examples, the 5G CPE module 3 can convert the base station signals it receives into WiFi signals for user terminal devices to access. Of course, the 5G CPE module 3 can also reserve LAN ports to facilitate user expansion through a wireless routing AP.

[0087] It should be noted that the antenna in the present disclosure is a transceiving antenna, that is, it can be used as a receiving antenna and a transmitting antenna at the same time, that is, it can not only realize the transmission of electromagnetic wave signals but also realize the reception of electromagnetic wave signals. In order to ensure that the base station signals and the terminal signals can be transmitted at the same time and improve the signal transmission rate, the communication device of the present disclosure is also provided with a first isolation module 41 and a second isolation module 42 for separating the base station signals and the terminal signals. Specifically, the first isolation module 41 is arranged between the antenna module 1 and the signal processing module 2, and the second isolation module 42 is arranged between the signal processing module 2 and the 5G CPE module 3. By arranging the isolation modules 41 / 42, the signal transmission rate can be improved, the signal delay can be reduced, and the user experience can be improved.

[0088] In some examples, the antenna module 1 can include a plurality of antenna units 11, all of which are directional antennas, and the beam directions of the respective antenna units 11 are different, that is, each antenna unit 11 can receive and radiate electromagnetic waves in different directions. In this way, the antenna module 1 can radiate electromagnetic wave energy to a specific direction or receive electromagnetic wave energy from a specific direction, thereby improving the directivity of the antenna module 1 and the security of communication. In other examples, the antenna module 1 can include only one antenna unit 11, and the antenna unit 1 is an omnidirectional antenna, that is, one antenna unit 11 can receive signals from all directions and radiate signals in all directions. In this way, under the premise of ensuring that the signals can be normally transmitted, the number of antenna units 11 can be reduced, thereby reducing the cost, and since the failure rate of omnidirectional antennas is low, the maintenance cost can also be reduced. The specific structure of the antenna module 1 and the communication device of the present disclosure will be introduced below in combination with specific embodiments.

[0089] First, the embodiment in which the antenna module 1 includes a plurality of antenna units 11 and each antenna unit 11 is a directional antenna is introduced.

[0090] Figure 2 is a structural schematic diagram of the antenna module 1 provided by the present disclosure. As shown in Figure 2, the antenna module 1 is an omnidirectional antenna device, each antenna unit 11 in the antenna module 1 covers a certain angle range, and the angle ranges covered by the respective antenna units 11 are different. For example, the antenna module 1 in Figure 2 adopts a six-sector setting. Specifically, the antenna module 1 includes a bearing structure, and the antenna units 11 are arranged on the side of the bearing structure. The bearing structure is a hollow six-prism, and each side of the prism is provided with an antenna unit 11. Each antenna unit 11 includes two first dipoles 111 arranged side by side, two second dipoles 112 arranged between the two first dipoles 111, and an auxiliary dipole 114 arranged between the two second dipoles 112. It should be noted that the structure of the auxiliary dipole 114 is exactly the same as that of the other two second dipoles 112, but it is not used to transmit signals in actual use in order to ensure the integrity of the antenna. In this way, each antenna unit 11 includes two first dipoles 111 and two second dipoles 112, and the antenna module 1 includes twelve first dipoles 111 and twelve second dipoles 112. Each dipole is provided with a corresponding signal transmission link, that is, each dipole can transmit base station signals and terminal signals. It should be noted that the first dipole 111 and the second dipole 112 are single-polarized dipoles, that is, the signals radiated by the first dipole 111 and the second dipole 112 have a specific polarization direction, which can be, for example, horizontal polarization, vertical polarization, ±45° polarization, etc.

[0091] Specifically, the working frequency band of the first dipole is 700 MHz in FDD frequency division mode, the working frequency band of the second dipole is 2.6 GHz in TDD time division mode, and the first dipole and the second dipole are designed as a transceiver integrated common aperture. In order to facilitate description, the first dipole is referred to as a low-frequency dipole 111, and the second dipole is referred to as a high-frequency dipole 112.

[0092] On the communication link between the low-frequency vibrator 111, the signal processing module 2 and the 5G CPE module 3, the first isolation module 41 includes a first duplexer, the second isolation module 42 includes a second duplexer, and the first duplexer is connected between the low-frequency vibrator 111 and the signal processing module 2, and the second duplexer is connected between the signal processing module 2 and the 5G CPE module 3. On the communication link between the high-frequency vibrator 112, the signal processing module 2 and the 5G CPE module 3, the first isolation module 41 includes a first circulator, the second isolation module 42 includes a second circulator, and the first circulator is connected between the high-frequency vibrator 112 and the signal processing module 2, and the second circulator is connected between the signal processing module 2 and the 5G CPE module 3. That is, in the communication link for transmitting low-frequency signals, the first duplexer and the second duplexer are configured to separate base station signals and terminal signals. In the communication link for transmitting high-frequency signals, the first circulator and the second circulator are configured to separate base station signals and terminal signals. The duplexer and the circulator can isolate the base station signals and the terminal signals, and ensure that the receiving and the transmitting can work normally at the same time.

[0093] Further, with reference to FIGS. 2 and 3, in order to reduce the mutual influence between the high-frequency vibrator 112 and the low-frequency vibrator 111, the height of the high-frequency vibrator 112 is different from the height of the low-frequency vibrator 111. Specifically, for each of the high-frequency vibrator 112 and the low-frequency vibrator 111 in each antenna unit 11, the high-frequency vibrator 112 and the low-frequency vibrator 111 are arranged side by side, and the height of the low-frequency vibrator 111 in the direction away from the bearing structure is greater than the height of the high-frequency vibrator 112 in the direction away from the bearing structure.

As shown in FIGS. 4-6, the low-frequency vibrator 111 according to an embodiment of the present disclosure includes a first reference electrode 102, a first radiating structure 101 and a first transmission line 103. The first reference electrode 102 is arranged on a bearing structure, the first reference electrode 102 is arranged on the bearing structure, the first reference electrode 102 has a first hollow part V3, and the first radiating structure 101 is arranged on the bearing structure through the first hollow pattern; and the first transmission line 103 is connected with the first radiating structure 101. Wherein, the first reference electrode 102 and the first radiating structure 101 can form a current loop, and the first transmission line 103 is used for transmitting radio frequency signals for the first radiating structure 101.

[0095] The first radiation structure 101 includes a first support assembly 1013, a first radiation electrode 1011 and a second radiation electrode 1012. The first support assembly 1013 can include a first support part 1013a and a second support part 1013b arranged side by side, and a first connecting part 1013c connecting the first support part 1013a and the second support part 1013b. The first connecting part 1013c is arranged on the carrier structure and located in the first hollow part V3. One end of the first support part 1013a is connected to the first connecting part 1013c, and the other end is connected to the first radiation electrode 1011. One end of the second support part 1013b is connected to the first connecting part 1013c, and the other end is connected to the second radiation electrode 1012. The first transmission line 103 is connected to the first radiation electrode 1011 and connected to the first connecting electrode 104 through a first via hole penetrating the first radiation electrode 1011. The first connecting electrode 104 is connected to the second radiation electrode 1012.

[0096] Referring to FIG. 4, the first support part 1013a and the second support part 1013b in the first support assembly 1013 are integrated with the first connecting part 1013c. In order to provide stable support, the width of the part of the first connecting part 1013c located on the carrier structure is greater than the distance between the first support part 1013a and the second support part 1013b.

[0097] Referring to FIG. 4, the first radiation electrode 1011 includes a first main body part 1011a and a first fixed part 1011b connected to the first main body part 1011a. The second radiation electrode 1012 includes a second main body part 1012a and a second fixed part 1012b connected to the second main body part 1012a.

The first transmission line 103 is connected to the first fixed part 1011b and connected to the first connecting electrode 104 through a first via hole penetrating the first fixed part 1011b. The first connecting electrode 104 is connected to the second fixed part 1012b. In this case, by arranging the first opening V1 on the first main body part 1011a and the second opening V2 on the second main body part 1012a, the current path can be extended, and the gain can be improved.

[0098] Further, the outer contour of the first main body part 1011a and the second main body part 1012a each includes a plurality of sides, and any two adjacent sides of the outer contour of the first main body part 1011a form an obtuse angle; any two adjacent sides of the outer contour of the second main body part 1012a form an obtuse angle. Since the inner angles of the first main body part 1011a and the second main body part 1012a are obtuse angles, electromagnetic wave reflection can be reduced, and loss can be reduced. Further, the first opening V1 has the same shape as the outer contour of the first main body part 1011a; the second opening V2 has the same shape as the outer contour of the second main body part 1012a.

As shown in FIGS. 10-12, the high-frequency vibrator 112 according to an embodiment of the present disclosure includes a second reference electrode 202, a second radiating structure 201, and a second transmission line 203. The second reference electrode 202 is disposed on a carrier structure, the second reference electrode 202 has a second hollow part V4, the second radiating structure 201 passes through the second hollow part V4 and is disposed on the carrier structure; and the second transmission line 203 is connected to the second radiating structure 201. The second reference electrode 202 and the second radiating electrode 1012 can form a current loop, and the second transmission line 203 is used to transmit a radio frequency signal to the second radiating structure 201.

[0100] The second radiation structure 201 includes a third radiation electrode 2011, a fourth radiation electrode 2012, a second electrode 204, and a second support assembly 2013. The second support assembly 2013 can include a third support part 2013a and a fourth support part 2013b arranged side by side, and a second connecting part 2013c connecting the third support part 2013a and the fourth support part 2013b. The second connecting part 2013c is arranged on the bearing structure and located in the second hollow part V4. One end of the third support part 2013a is connected to the second connecting part 2013c, and the other end is connected to the third radiation electrode 2011. One end of the fourth support part 2013b is connected to the second connecting part 2013c, and the other end is connected to the fourth radiation electrode 2012. The second transmission line 203 is connected to the third radiation electrode 2011 and connected to the second electrode 204 through a second via hole penetrating the third radiation electrode 2011. The second electrode 204 is connected to the fourth radiation electrode 2012.

[0101] Referring to FIG. 7, the third support part 2013a and the fourth support part 2013b in the second support assembly 2013 are integrated with the second connecting part 2013c. In order to provide stable support, the width of the part of the second connecting part 2013c on the bearing structure is greater than the distance between the third support part 2013a and the fourth support part 2013b.

[0102] Continuing to refer to FIG. 7, the third radiation electrode 2011 and the fourth radiation electrode 2012 each include oppositely arranged first and second side edges, oppositely arranged third and fourth side edges, and first and second connecting edges. For the third radiation electrode 2011, the first side edge has two ends connected to the third and fourth side edges, respectively. One end of the second side edge is connected to the third side edge through the first connecting edge, and the other end of the second side edge is connected to the fourth side edge through the second connecting edge. The two inner angles formed by the first connecting edge and the third and second side edges are obtuse angles. For the fourth radiation electrode 2012, the first side edge is adjacent to the first side edge of the third radiation patch. The first side edge has two ends connected to the third and fourth side edges, respectively. One end of the second side edge is connected to the third side edge through the first connecting edge, and the other end of the second side edge is connected to the fourth side edge through the second connecting edge. The two inner angles formed by the first connecting edge and the third and second side edges are obtuse angles. That is, the third radiation electrode 2011 and the fourth radiation electrode 2012 can each be obtained by cutting a square patch. The third radiation electrode 2011 and the fourth radiation electrode 2012 of this structure not only lengthen the current path to achieve antenna miniaturization, but also reduce microwave loss.

[0103] When the low-frequency vibrator 111 adopts the structure shown in FIG. 4, the maximum side length of the first radiation electrode 1011 and the second radiation electrode 1012 is 22 mm, and the height of the first support assembly 1013 is 98 mm. The horizontal direction diagram obtained by simulating the low-frequency vibrator 111 is shown in FIG. 10, and the gain of the low-frequency vibrator 111 can reach 7.6 dBi. When the high-frequency vibrator 112 adopts the structure shown in FIG. 7, the maximum side length of the third radiation electrode 2011 and the fourth radiation electrode 2012 is 18 mm, and the height of the first support assembly 1013 is 36.5 mm. The horizontal direction diagram obtained by simulating the low-frequency vibrator 111 is shown in FIG. 11, and the gain of the low-frequency vibrator 111 can reach 8.3 dBi.

[0104] When the high-frequency vibrator 112 and the low-frequency vibrator 111 are used to form the antenna unit 11, and six antenna units 11 are used to form the antenna module 1, the specific structure is shown in FIG. 2. At this time, the direction diagram of the antenna module 1 at a low frequency of 700 MHz is shown in FIG. 12, and the direction diagram of the antenna module 1 at a high frequency of 2.6 GHz is shown in FIG. 13. As shown in FIGS. 12 and 13, the antenna module 1 of the embodiment of the present disclosure can achieve a beam gain of 9.2 dBi, a horizontal plane beam width of 77°, and a vertical plane beam width of 45° at a low frequency, and a horizontal plane coverage roll-off of only 1.9 dB; and can achieve a beam gain of 12.2 dBi, a horizontal plane beam width of 53°, and a vertical plane beam width of 20° at a high frequency, and a horizontal plane coverage roll-off of 2.9 dB, which has a very large coverage capability.

[0105] In some examples, the second reference electrode 202 in the second radiation structure 201 and the first reference electrode 102 in the first radiation structure 101 can be an integrally formed structure. This structure is simple and easy to control.

[0106] In some examples, the first radiation structure 101 in the low-frequency vibrator 111 and the second radiation structure 201 in the high-frequency vibrator 112 can both adopt a metal sheet.

[0107] In some examples, the bearing structure can adopt a hollow structure, and the feed network in the antenna module 1 can be arranged in the hollow cavity of the bearing structure and connected with the first transmission line 103 and the second transmission line 203 in each antenna unit 11. For example, the feed network can include a first feed network and a second feed network, the first transmission line 103 in each antenna unit 11 can be electrically connected with the first feed network through a via hole penetrating through the bearing structure, and the second transmission line 203 in each antenna unit 11 can be electrically connected with the second feed network through a via hole penetrating through the bearing structure. At this time, the structure of the antenna module 1 is simple and easy to realize miniaturization.

[0108] In some examples, referring to FIGS. 2 and 3, the antenna unit 11 further comprises a first isolation component 113 corresponding to the high-frequency vibrator 112, and a normal projection of the high-frequency vibrator 112 on the bearing structure is located within a region defined by a normal projection of the first isolation component 113 on the bearing structure. The first isolation component 113 prevents mutual interference between the high-frequency vibrator 112 and the low-frequency vibrator 111. The first isolation component 113 can be a ring-shaped fence structure formed by sequentially splicing isolation plates, for example, a square fence structure formed by sequentially splicing four isolation plates.

[0109] In some examples, referring to FIG. 2, the bearing structure can be composed of a plurality of bearing parts 12 connected in sequence, and one bearing part 12 is provided with one antenna unit 11. A second isolation component 13 is arranged between any two connected bearing parts 12, and one antenna unit 11 is arranged between two adjacent second isolation components 13. The second isolation component 13 prevents mutual interference between adjacent antenna units 11.

[0110] In some examples, the communication device further comprises a selection module 5 connected between the antenna module 1 and the signal processing module 2, which is configured to determine a target antenna unit to be connected in communication with the signal processing module 2 according to signal strength information of base station signals received by each vibrator in each antenna unit.

[0111] The following two specific structures of the selection module 5 are given in the embodiments of the present disclosure, and the two selection modules will be described in detail.

[0112] First example: FIG. 14 is a structural block diagram of the first example of the selection module in the embodiments of the present disclosure. As shown in the figure, the selection module 5 comprises a plurality of signal coupling units 51, a plurality of signal preprocessing units 52 corresponding to the signal coupling units 51, a first selection unit 53, a signal detection unit 54, a control unit 55, and a second selection unit 56.

[0113] Specifically, the signal coupling unit 51 is configured to couple the base station signal received by the antenna unit corresponding thereto to the signal preprocessing unit 52.

[0114] The signal preprocessing unit 52 is configured to preprocess the signal received thereby and transmit it to the first selection unit 53. In some examples, the signal preprocessing unit can comprise a low-noise signal amplifier, and the signal processed by the amplifier has good anti-interference ability. In other examples, the signal preprocessing unit can further comprise a filter to reduce the noise of the signal and improve the reliability of the signal.

[0115] The first selection unit 53 is configured to be controlled by the processor to turn on its connection with the signal preprocessing unit 52 in turn, and is configured to transmit the received signal part to the 5G CPE module 3 after turning on, so as to facilitate user terminal access, and another part to the signal detection unit 54. It should be noted that because the signal detection unit 54 is only used to analyze the strength of the base station signal, and does not need to take this part of the signal as the radiation signal, the base station signal transmitted to the signal detection unit is much less than the base station signal transmitted to the 5G CPE module, preventing energy waste.

[0116] FIG. 17 is a structural schematic diagram of a first selection module provided by an embodiment of the present disclosure, and FIG. 18 is another structural schematic diagram of a first selection module provided by an embodiment of the present disclosure. In some examples, as shown in FIG. 17, the first selection unit 53 can include eight double-pole four-throw switches (DP4T) (only four double-pole four-throw switches are schematically shown in the figure), each of which includes two fixed terminal contacts and four movable terminal contacts. The eight double-pole four-throw switches include four first double-pole four-throw switches (i.e., the four double-pole four-throw switches shown in FIG. 17) and four second double-pole four-throw switches (not shown in FIG. 17, which have the same structure as the first double-pole four-throw switches), the four first double-pole four-throw switches are divided into three first-level first double-pole four-throw switches and one second-level first double-pole four-throw switch, and the four second double-pole four-throw switches are divided into three first-level second double-pole four-throw switches and one second-level second double-pole four-throw switch.

[0117] Specifically, the four movable terminal contacts of the first-level first double-pole four-throw switch are respectively connected to one of the first oscillators 111, one of the two fixed terminal contacts of the first-level first double-pole four-throw switch is suspended, and the other is connected to the movable terminal contact of the second-level first double-pole four-throw switch. Three of the four movable terminal contacts of the second-level first double-pole four-throw switch are connected to the three first-level first double-pole four-throw switches, and the other movable terminal contact is suspended. One of the two fixed terminal contacts of the second-level first double-pole four-throw switch is connected to the signal preprocessing unit 52, and the other is connected to the signal detection unit 54.

[0118] The four movable terminal contacts of the first-level second double-pole four-throw switch are respectively connected to one of the second oscillators 112, one of the two fixed terminal contacts of the first-level second double-pole four-throw switch is suspended, and the other is connected to the movable terminal contact of the second-level second double-pole four-throw switch. Three of the four movable terminal contacts of the second-level second double-pole four-throw switch are connected to the three first-level second double-pole four-throw switches, and the other movable terminal contact is suspended. One of the two fixed terminal contacts of the second-level second double-pole four-throw switch is connected to the signal preprocessing unit 52, and the other is connected to the signal detection unit 54.

[0119] In some examples, as shown in FIG. 17, the first selection unit 53 can include six double-pole four-throw switches (DP4T). The six double-pole four-throw switches are divided into three first double-pole four-throw switches and three second double-pole four-throw switches. The three first double-pole four-throw switches are divided into two first-stage first double-pole four-throw switches and one second-stage first double-pole four-throw switch. The three second double-pole four-throw switches are divided into two first-stage second double-pole four-throw switches and one second-stage second double-pole four-throw switch.

[0120] Specifically, the six movable contacts of the first-stage first double-pole four-throw switch are respectively connected to one of the first oscillators 111, and the two fixed contacts of the first-stage first double-pole four-throw switch are connected to the two movable contacts of the second-stage first double-pole four-throw switch. Four of the six movable contacts of the second-stage first double-pole four-throw switch are connected to the two first-stage first double-pole four-throw switches, and the other two movable contacts are suspended. One of the two fixed contacts of the second-stage first double-pole four-throw switch is connected to the signal preprocessing unit 52, and the other is connected to the signal detection unit 54.

[0121] The six movable contacts of the first-stage second double-pole four-throw switch are respectively connected to one of the second oscillators 112, and the two fixed contacts of the first-stage second double-pole four-throw switch are connected to the two movable contacts of the second-stage second double-pole four-throw switch. Four of the six movable contacts of the second-stage second double-pole four-throw switch are connected to the two first-stage second double-pole four-throw switches, and the other two movable contacts are suspended. One of the two fixed contacts of the second-stage second double-pole four-throw switch is connected to the signal preprocessing unit 52, and the other is connected to the signal detection unit 54.

[0122] Compared with the scheme of using double-pole four-throw switches, the scheme of using double-pole six-throw switches can reduce the number of switches, reduce the complexity of design, and reduce the failure rate. However, the scheme of using double-pole four-throw switches can achieve more precise signal control and improve the performance and flexibility of the communication device. In actual application scenarios, different choices can be made according to different requirements. The signal detection unit 54 is configured to detect the signals received thereby, obtain signal strength information of the base station signals, and transmit the signal strength information to the control unit 55. In some examples, the signal strength information can include signal received power. The greater the signal received power, the better the signal can receive the base station signal.

[0123] The control unit 55 is configured to generate corresponding control signals according to the signal strength information of each base station signal received thereby and transmit the control signals to the second selection unit 56. For example, after receiving the signal strength information of each base station signal, the control unit determines the signal with the greatest received power and sends a first control signal to the second selection unit.

[0124] The second selection unit 56 is configured to determine the target antenna element based on the control signal and connect it to the 5G CPE module 3. For example, after receiving the first control signal, it determines the antenna element corresponding to the signal with the highest received power as the target antenna element and connects the target antenna element to the 5G CPE module.

[0125] Second example: Figure 15 is a structural block diagram of a second example of the selection module of this disclosure. As shown in Figure 15, the selection module includes multiple signal coupling units 51, a first selection unit 53, a signal preprocessing unit 52, a signal detection unit 54, a control unit 55, and a second selection unit 56.

[0126] Specifically, the signal coupling unit 51 is configured to couple the base station signal received by the antenna unit corresponding to it to the first selection unit 53.

[0127] The first selection unit 53 is configured to, under the control of the processor, sequentially select its connection with the signal coupling unit, and is configured to transmit a portion of the received signal to the signal preprocessing unit 52 and another portion to the 5G CPE module 3 after selection. It should be noted that, because the signal detection unit 52 is only for analyzing the strength of the base station signal and does not need to treat this portion of the signal as a radiated signal, the base station signal transmitted to the signal preprocessing unit 52 is much smaller than the base station signal transmitted to the 5G CPE module 3, to prevent energy waste.

[0128] The signal preprocessing unit 52 is configured to preprocess the received signal and transmit it to the signal detection unit 54. In some examples, the signal preprocessing unit 52 may include a low-noise signal amplifier, which amplifies the signal to provide good anti-interference capability. In other examples, the signal preprocessing unit 52 may also include a filter to reduce signal noise and improve signal reliability.

[0129] The signal detection unit 54 is configured to detect the received signal, acquire signal strength information of the base station signal, and transmit the signal strength information to the control unit 55. In some examples, the signal strength information 54 may include signal receiving power; the higher the signal receiving power, the better it can receive the base station signal.

[0130] The control unit 55 is configured to generate a corresponding control signal and send it to the second selection unit 56 based on the signal strength information of each base station signal it receives. For example, after receiving the signal strength information of each base station signal, the control unit 55 determines the signal with the highest received power and sends a first control signal to the second selection unit 56.

[0131] The second selection unit 56 is configured to determine the target antenna unit according to the control signal and connect it with the 5G CPE module 3 in communication. For example, after receiving the first control signal, the antenna unit corresponding to the signal with the largest received power is determined as the target antenna unit, and the target antenna unit is connected with the 5G CPE module 3 in communication.

[0132] It should be noted that the second example is different from the first example in that the relative positions of the first selection unit 53 and the signal preprocessing unit 52 are different. In the second example, the base station signal transmitted through the signal coupling unit 51 is first processed by the first selection unit 53, and then the signal with larger received power is selected and amplified and filtered, which can reduce a large number of signal amplifiers and filters, thereby reducing the cost.

[0133] In other examples, as shown in FIG. 16, the first selection unit 53 can also be arranged between the antenna unit 11 and the isolation module, that is, the selection module 5 can be divided into two parts, the first part includes the signal coupler 51 and the first selection unit 53, and the second part includes the signal preprocessing unit 52, the signal detection unit 54, the control unit 55 and the second selection unit 56. Among them, the first part is arranged between the antenna module 1 and the first isolation module 41, and the second part is arranged between the first isolation module 41 and the 5G CPE module 3. Such arrangement not only can reduce the amplifiers and filters in the signal preprocessing unit 52, but also can reduce the first diplexer and the first circulator in the first isolation module 41, thereby further reducing the cost under the premise of ensuring the receiving sensitivity.

[0134] Next, a specific embodiment in which the antenna module 1 includes one antenna unit 11 and the antenna unit 11 is an omnidirectional antenna is introduced.

[0135] In this embodiment, the antenna unit 11 includes at least one first oscillator and at least one second oscillator. The same as the above embodiment is that the working frequency band of the first oscillator is N28 frequency band using FDD frequency division working mode, and the working frequency band of the second oscillator is N41 frequency band using TDD time division working mode. Different from the above embodiment is that the first oscillator and the second oscillator in this embodiment are both dual-polarized oscillators, that is, the first oscillator and the second oscillator can both transmit two signals with different polarization directions. For example, the first oscillator transmits horizontal polarization signals and vertical polarization signals of N28 frequency band, and the second oscillator transmits horizontal polarization signals and vertical polarization signals of N41 frequency band. Of course, the polarization directions of the two signals with different polarization directions transmitted by each oscillator can also be ±45°, or can also be other angles, which are not limited by the present disclosure. It should be noted that the structure of the first oscillator in this embodiment is different from that of the first oscillator 111 in the above, and the first oscillator in this embodiment can be, for example, a dipole antenna or a Yagi antenna, etc. Similarly, the second oscillator can also adopt an omnidirectional antenna such as a dipole antenna or a Yagi antenna, which is not limited by the present disclosure, and therefore the present application does not provide a specific structure diagram of the first oscillator and the second oscillator.

[0136] Since the first oscillator uses FDD frequency division working mode, in the communication link of the first oscillator, the first isolation module 41, the signal processing module 2, the second isolation module 42 and the 5G CPE module 3, the working frequencies of the uplink signal (i.e. the signal from the terminal to the base station) and the downlink signal (i.e. the signal from the base station to the terminal) can be set to be different, and the uplink signal and the downlink signal are separated by the first isolation module 41 and the second isolation module 42. The first isolation module 41 and the second isolation module 42 can include a diplexer, for example.

[0137] Since the second oscillator uses TDD time division working mode, the uplink signal and the downlink signal can be controlled to be transmitted in different time periods. Specifically, in this example, the 5G CPE module 3 is also configured to generate a second control signal, the second control signal is a periodic signal, and the high and low levels of the second control signal can control which of the uplink signal and the downlink signal can be transmitted in the communication link.

[0138] Specifically, in the communication link of the second oscillator, the first isolation module 41, the signal processing module 2, the second isolation module 42 and the 5G CPE module 3, the signal processing module 2 includes a first signal processing link 21 and a second signal processing link 22, as shown in FIG. 19. Among them, the uplink signal transmitted by the terminal to the base station is transmitted through the first signal processing link 21, and the downlink signal transmitted by the base station to the terminal is transmitted through the second signal processing link 22.

[0139] Further, with continuous reference to FIG. 19, the communication link composed of the second oscillator, the first isolation module 41, the signal processing module 2, the second isolation module 42 and the 5G CPE module 3 further comprises a third selection unit 61 and a fourth selection unit 62. The first end of the third selection unit 61 is connected with the second oscillator through the first isolation module 41, the second end of the third selection unit 61 is connected with the first signal processing link 21, and the third end of the third selection unit 61 is connected with the second signal processing link 22. The fourth end of the fourth selection unit 62 is connected with the first signal processing link 21, the fifth end of the fourth selection unit 62 is connected with the second signal processing link 22, and the sixth end of the fourth selection unit 62 is connected with the second isolation module 42.

[0140] The third selection unit 61 is configured to select one of the first signal processing link 21 and the second signal processing link 22 to which the second oscillator is connected in response to a second control signal. The fourth selection unit 62 is configured to select one of the first signal processing link 21 and the second signal processing link 22 to which the second isolation module is connected in response to the second control signal. That is, under the control of the second control signal, the communication link composed of the second oscillator, the first isolation module 41, the signal processing module 2, the second isolation module 42 and the 5G CPE module 3 periodically transmits uplink signals and downlink signals to realize a time division duplex working mode. In some specific embodiments, the third selection unit 61 and the fourth selection unit 62 may, for example, comprise a single-pole double-throw switch.

[0141] It should be noted that in the above embodiment, the working frequencies of the horizontal polarization signals and the vertical polarization signals of the N41 frequency band transmitted in the second oscillator are different, so they can be transmitted through the same communication link and separated by the first isolation module 41 and the second isolation module 42 in the communication link. The first isolation module 41 and the second isolation module 42 may, for example, comprise a duplexer.

[0142] Of course, the horizontal polarization signals and the vertical polarization signals of the N41 frequency band transmitted in the second oscillator can work at the same working frequency, in which case the horizontal polarization signals and the vertical polarization signals need to be transmitted through two different communication links.
