Abstract
Description
[Technical field]
[0001] The present disclosure relates to wireless communication devices. [Background technology]
[0002] The material described in this section is merely intended to provide background information for the present disclosure and may not constitute prior art.
[0003] 2. Description of the Related Art Wireless communication devices used for transmitting and receiving wireless signals are generally installed in outdoor environments, such as on the rooftops of buildings.
[0004] Research has been conducted in many areas to improve the size and design of wireless communication devices so that they do not mar the aesthetic appearance of buildings. However, improvements in design and size have been limited in reality from the standpoint of maintaining the functionality of wireless communication devices.
[0005] In particular, as the number of frequency bands used for communication increases, the installation of additional wireless communication devices becomes unavoidable. By disposing wireless communication devices covering new frequency bands, the proportion of space occupied by the wireless communication devices increases further.
[0006] Furthermore, even after a wireless communication device is installed, if the frequency band it covers changes over time, the wireless communication device must be replaced as a whole. Summary of the Invention [Problem to be solved by the invention]
[0007] Therefore, the main objective of the present disclosure is to additionally deploy wireless communication devices for other frequency bands without increasing the size of the wireless communication devices.
[0008] Furthermore, a main objective of the present disclosure is to enable easy installation using a cartridge-type wireless communication device when an additional wireless communication device covering a new frequency band needs to be placed in an area where existing wireless communication devices are placed, without having to replace the entire wireless communication device.
[0009] Also, a main object of the present disclosure is to detach a wireless communication device that covers a new frequency band while maintaining the operation of an existing wireless communication device.
[0010] Furthermore, when the frequency band covered by an existing wireless communication device changes at a location where the device is installed, the main purpose is to reduce replacement costs by replacing only the cartridge-type wireless communication device.
[0011] Another main objective is to reduce manufacturing costs by producing a variety of small cartridge-type antennas instead of producing a variety of wireless communication devices according to the frequency bands they cover.
[0012] The problems to be solved by the present invention are not limited to those mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the following description. [Means for solving the problem]
[0013] According to one embodiment of the present disclosure, a wireless communication device is provided that includes a first antenna housing, a mounting space formed in at least a portion of the first antenna housing, and a plurality of first antenna elements disposed within the first antenna housing and configured to transmit and receive a first signal. Effect of the Invention
[0014] According to an embodiment of the present disclosure, a wireless communication device has an advantage that a mounting space is secured within a first communication device, and a second communication device can be mounted within the mounting space without increasing the size of the wireless communication device.
[0015] In addition, there is an advantage that the second communication device can be easily attached or replaced while the operation of the first communication device is maintained. [Brief description of the drawings]

[0017] Some embodiments of the present disclosure will be described in detail below with reference to the drawings. When referring to components in each drawing, it should be noted that the same components are given the same reference numerals as much as possible even if they are displayed in different drawings. In describing the present disclosure, if a detailed description of related known configurations or functions is deemed to obscure the gist of the present disclosure, the detailed description will be omitted.
[0018] In describing components of the embodiments of the present disclosure, reference numerals such as 1, 2, i), ii), a), b) may be used. Such reference numerals are used to distinguish the components from other components, and do not limit the essence or order or sequence of the components. When a part in the specification "includes" or "has" a certain component, this does not mean that the other components are excluded, but that the other components may be further included, unless explicitly stated to the contrary.
[0019] In this specification, "width" refers to the length in a direction parallel to the X-axis with reference to Fig. 1, and "thickness" refers to the length in a direction parallel to the Z-axis with reference to Fig. 1. Additionally, "longitudinal direction" refers to the direction parallel to the Y-axis.
[0020] FIG. 1 is a perspective view of a wireless communication device according to an embodiment of the present disclosure.
[0021] FIG. 2 is a cross-sectional view taken along the line AA in FIG.
[0022] FIG. 3 is an exploded perspective view of a wireless communication device according to an embodiment of the present disclosure.
[0023] 1 to 3, a wireless communication device 10 includes a first communication device 100 and a second communication device 200. The first communication device 100 includes a first antenna housing 110, a first input / output port 120, a plurality of first antenna elements 130, and a mounting space 140. The second communication device 200 includes a second antenna housing 210, a second input / output port 220, and a plurality of second antenna elements 230.
[0024] One side of the first antenna housing 110 is configured as a radome. The first antenna housing 110 has an accommodation space formed therein, and accommodates a plurality of first antenna elements 130 and other internal boards in the accommodation space. Thus, the first antenna housing 110 can protect the first antenna elements 130 and other internal boards from external impact.
[0025] The first antenna housing 110 has a shape in which the length in the longitudinal direction is relatively longer than the length in the width direction.
[0026] In a first communication device 100 according to one embodiment of the present disclosure, one of the widthwise length and the lengthwise length of the first antenna housing 110 is configured to be relatively longer than the other, thereby ensuring a storage space with a relatively wide cross-sectional area.
[0027] A plurality of first input / output ports 120 are formed on one side of the first antenna housing 110. The first communication device 100 uses the first input / output ports 120 to connect to an external device or another wireless communication device 10.
[0028] The first plurality of input / output ports 120 may include an alarm port, an optical port, a power port, and an RTS port, although the present disclosure is not limited thereto.
[0029] A total of twelve first input / output ports 120 are shown in FIG. 1, although the present disclosure is not limited in this respect.
[0030] A plurality of first antenna elements 130 are disposed inside the first antenna housing 110 and configured to transmit and receive a first signal, where the first signal has a specific frequency band, preferably a frequency band of 698 MHz to 894 MHz or a frequency band of 1695 MHz to 2400 MHz, although the present disclosure is not limited thereto and may have different frequency bands depending on purposes and applications.
[0031] 2, two first antenna elements 130 arranged in the width direction are grouped into one set and spaced apart from each other at a preset interval along the longitudinal direction. The larger the frequency band of the first signal, the narrower the interval D1 between the two first antenna elements 130 arranged in the width direction. For example, the interval D1 is 0.5 lambda to 1.0 lambda. That is, the smaller the frequency of the first signal, the longer the wavelength, and the wider the interval D1.
[0032] The mounting space 140 is formed in at least a portion of the first antenna housing 110. The mounting space 140 is formed with at least a portion open on one side in the longitudinal direction of the first antenna housing 110. Preferably, the mounting space 140 is at least a portion open on one side where the first input / output port 120 is arranged.
[0033] The mounting space 140 is formed in at least a part of the space between the two first antenna elements 130 arranged in the width direction. The width of the mounting space 140 is smaller than the interval D1 between the two first antenna elements 130 arranged in the width direction. The mounting space 140 is also formed between the two first antenna elements 130 arranged in the width direction.
[0034] The present disclosure has a technical feature in that the space of the interval D1 formed by the frequency of the first signal is used as the mounting space 140 to mount a communication device that transmits and receives signals of other frequency bands, thereby securing various frequency bands without increasing the overall volume of the wireless communication device 10. This has the effect of increasing the utilization of space in the limited installation space of the wireless communication device. However, the multiple first antenna elements 130 do not necessarily have to be arranged in two rows along the longitudinal direction at an interval of D1 in the width direction as shown in FIG.
[0035] The second antenna housing 210 is configured to be inserted into the mounting space 140. The second antenna housing 210 is configured to be inserted into and positioned in the mounting space 140.
[0036] The second antenna housing 210 has an accommodation space formed therein, and can accommodate a plurality of second antenna elements 230 and other internal boards in the accommodation space, so that the second antenna housing 210 can protect the second antenna elements 230 and other internal boards from external impact.
[0037] The second antenna housing 210 has a shape in which the length in the longitudinal direction is relatively longer than the length in the width direction.
[0038] Since the second communication device 200 is disposed in the mounting space 140 of the first communication device 100, the overall size of the wireless communication device 10 does not change even if the second communication device 200 is added. In other words, the present disclosure has a technical feature that the wireless communication device 10 can transmit and receive signals in various frequency bands while maintaining the size of the wireless communication device 10.
[0039] A plurality of second input / output ports 220 are formed on one side of the second antenna housing 210 .
[0040] The second communication device 200 uses a second input / output port 220 to connect to an external device or another wireless communication device 10 .
[0041] The plurality of second input / output ports 220 may include an alarm port, an optical port, a power port, and an RTS port, although the present disclosure is not limited thereto.
[0042] When the second communication device 200 is mounted in the mounting space 140 of the first communication device 100 , the multiple second input / output ports 220 are located on the same plane as the multiple first input / output ports 120 .
[0043] The number of the second input / output ports 220 may vary as necessary. Preferably, the number of the second input / output ports 220 is four to eight. The number of the second input / output ports 220 of the second communication device 200 is determined according to the environment in which the wireless communication device 10 is installed.
[0044] The plurality of second antenna elements 230 are disposed inside the second antenna housing 210 and are configured to transmit and receive a second signal having a different frequency band from the first signal. Here, the frequency band of the first signal is smaller than the frequency band of the second signal. That is, the second antenna element 230 can transmit and receive a signal having a higher frequency band than the first antenna element 130. For example, the second signal has a frequency band of 3500 MHz to 4000 MHz. Therefore, the interval D2 between two second antenna elements 230 arranged in the width direction is formed narrower than D1. However, the present disclosure is not limited to this, and the second signal has other different frequency bands. Note that the plurality of second antenna elements 230 do not necessarily have to be arranged in two rows along the longitudinal direction at an interval of D2 in the width direction as illustrated in FIG. 1. For example, the plurality of second antenna elements 230 may be arranged in a single row in the longitudinal direction at a distance.
[0045] FIG. 4 is an exploded perspective view of a wireless communication device according to another embodiment of the present disclosure.
[0046] As shown in FIG. 4, the mounting space 140 is formed so that the second communication device 200 is inserted from above the first communication device 100 .
[0047] In a situation where the first communication device 100 is already installed and multiple cables are connected to multiple first input / output ports 120, it is more convenient to insert and attach the second communication device 200 from the upper side in the thickness direction of the first communication device 100 as shown in FIG.
[0048] That is, the second communication device 200 can be mounted without stopping the operation of the first communication device 100 and without separately touching the multiple cables already connected to the multiple first input / output ports 120. The second communication device 200 is mounted and fixed in the mounting space 140 in a sliding manner.
[0049] FIG. 5 is a diagram showing a state in which the second communication device in FIG. 3 is replaced with a dummy cover.
[0050] FIG. 6 is a diagram showing a state in which the second communication device in FIG. 4 is replaced with a dummy cover.
[0051] When only the frequency band of the first signal is required depending on the environment in which the wireless communication device 10 is installed, there is no need to additionally install the second communication device 200. In such a case, the inside of the mounting space 140 can be protected from external contamination by using the dummy cover 300.
[0052] The dummy cover 300 is configured to cover the mounting space 140 in accordance with the shape of the first antenna housing 110. Fig. 5 shows the shape of the dummy cover 300 when the mounting space 140 is formed so that the second communication device 200 is mounted on the first communication device 100 in the longitudinal direction. Fig. 6 shows the shape of the dummy cover 300 when the mounting space 140 is formed so that the second communication device 200 is mounted from above the first communication device 100. As shown in Figs. 5 and 6, the dummy cover 300 is configured to correspond to the shape of the first antenna housing.
[0053] When the second communication device 200 is required additionally while the wireless communication device 10 covered with the dummy cover 300 is being used, the dummy cover 300 can be removed and the second communication device 200 can be attached. At this time, it is not necessary to interrupt the operation of the first communication device 100.
[0054] Therefore, the present disclosure has a technical feature that the operation of the existing wireless communication device 10 is not interrupted even when the second communication device 200 is additionally installed, and therefore the communication user is not inconvenienced.
[0055] The above description is merely an illustrative example of the technical idea of the present embodiment, and a person having ordinary knowledge in the technical field to which the present embodiment belongs may make various modifications and variations without departing from the essential characteristics of the present embodiment. Therefore, the present embodiment is intended to explain, rather than limit, the technical idea of the present embodiment, and the scope of the technical idea of the present embodiment is not limited by such an embodiment. The scope of protection of the present embodiment should be interpreted according to the claims, and all technical ideas within the scope equivalent thereto should be interpreted as being included in the scope of the present embodiment.
