Technical Field
The present disclosure relates to a wireless communication device.
Background
The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
The wireless communication device is used for receiving and transmitting wireless signals, and is preferably installed in an outdoor environment such as a building roof.
In order to avoid the wireless communication device from interfering with the external appearance of a building, studies for improving the size and external design of the wireless communication device are being variously conducted, but in view of maintaining the functions of the wireless communication device, it is realistic that the improvement of the design and the size is limited.
In particular, as the frequency band for communication increases, the addition of a wireless communication apparatus is unavoidable. The arrangement of the wireless communication device covering the new frequency band causes a further increase in the specific gravity of the space occupied by the wireless communication device.
Further, if the frequency band covered over time after the installation of the wireless communication device is changed, there is a disadvantage in that the entire wireless communication device needs to be completely removed and replaced.

Accordingly, a primary object of the present disclosure is to enable additional arrangement of wireless communication devices of other frequency bands without increasing the size of the wireless communication devices.
Further, a main object of the present disclosure is to make it possible to easily install a wireless communication device using a cassette type wireless communication device without replacing the entire wireless communication device when it is necessary to additionally arrange the wireless communication device for covering a new frequency band in an area where the wireless communication device has been arranged.
Further, a main object of the present disclosure is to attach and detach a wireless communication device for covering a new frequency band while maintaining an operation of a currently arranged wireless communication device.
Further, a main object of the present disclosure is to reduce replacement costs by replacing only a cassette type wireless communication device when it is necessary to change a covered frequency band at a place where the wireless communication device has been arranged.
Further, a main object of the present disclosure is to reduce manufacturing costs by producing various small-sized cassette antennas instead of producing various wireless communication devices based on a coverage band.
The technical problems to be solved by the present application are not limited to the above-described problems, and other technical problems not mentioned herein can be clearly understood by those skilled in the art from the following description.

Fig. 1 is a perspective view of a wireless communication device according to an embodiment of the present disclosure.
Fig. 2 is a sectional view in the direction A-A of fig. 1.
Fig. 3 is an exploded perspective view of a wireless communication device according to an embodiment of the present disclosure.
Referring to fig. 1-3, a wireless communication device 10 may include 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 an installation space 140. The second communication device 200 may include a second antenna housing 210, a second input-output port 220, and a plurality of second antenna elements 230.
One side of the first antenna housing 110 is formed of a radome (radome). The first antenna housing 110 is formed therein with an accommodating space in which a plurality of first antenna elements 130 and other internal substrates can be accommodated. Thus, the first antenna housing 110 may protect the first antenna element 130 and other internal substrates from external impact.
The first antenna housing 110 has a shape in which the length in the length direction is greater than the length in the width direction.
The first communication device 100 according to an embodiment of the present disclosure is configured such that one of the length in the width direction and the length in the length direction of the first antenna housing 110 is greater than the other, so that the accommodating space can be ensured to have a relatively wide sectional area.
The plurality of first input/output ports 120 may be formed at one side of the first antenna housing 110. The first communication device 100 is connectable to an external apparatus or other wireless communication device 10 using the first input output port 120.
The plurality of first input-output ports 120 may include an alarm port, an optical port, a power port, and an RTS port, but the present disclosure is not limited thereto.
Fig. 1 shows a total of 12 first input-output ports 120, but the present disclosure is not limited thereto.
The plurality of first antenna elements 130 are disposed inside the first antenna housing 110 and are used for transceiving first signals. Wherein the first signal has a specific frequency band, preferably may have a frequency band of 698MHz to 894MHz or a frequency band of 1695MHz to 2400 MHz. However, the present disclosure is not limited thereto, and may have other frequency bands according to the purpose and use.
Referring to fig. 2, two first antenna elements 130 arranged in the width direction are provided as a group, and are arranged at intervals of a preset pitch in the length direction. The larger the frequency band of the first signal has, the smaller the spacing D1 between the two first antenna elements 130 arranged in the width direction becomes. For example, the spacing D1 may be 0.5lamda to 1.0lamda. That is, the smaller the frequency of the first signal, the larger the wavelength becomes, and the pitch D1 becomes wider.
A mounting space 140 is formed in at least a portion of the first antenna housing interior 110. At least a portion of the first antenna housing 110 may be opened at one side in the length direction and an installation space 140 may be formed. Preferably, the installation space 140 is at a side where the first input output port 120 is disposed and at least a portion thereof is opened.
The mounting space 140 may form at least a portion of a space between the two first antenna elements 130 arranged in the width direction. The width of the installation space 140 is smaller than the interval D1 between the two first antenna elements 130 arranged in the width direction. Further, the mounting space 140 is formed between the two first antenna elements 130 arranged in the width direction.
The technical feature of the present disclosure is that by using the space D1 formed based on the first signal frequency as the installation space 140 and installing a communication device for transmitting and receiving signals of another frequency band, it is possible to ensure the use of various frequency bands without increasing the overall volume of the wireless communication device 10. This has the effect of increasing the space utilization in a limited installation space of the wireless communication device. However, the plurality of first antenna elements 130 are not necessarily arranged in two rows at a D1 pitch in the width direction and along the length direction as shown in fig. 1.
The second antenna housing 210 has a structure capable of being inserted into the installation space 140. The second antenna housing 210 has a structure inserted and disposed in the installation space 140.
The second antenna housing 210 has an accommodating space formed therein, and a plurality of second antenna elements 230 and other internal substrates can be accommodated in the accommodating space. Thus, the second antenna housing 210 may protect the second antenna element 230 and other internal substrates from external impact.
The second antenna housing 210 has a shape in which the length in the length direction is greater than the length in the width direction.
Since the second communication device 200 is disposed in the installation space 140 of the first communication device 100, the overall size of the wireless communication device 10 is not changed even if the second communication device 200 is added. That is, the present disclosure is characterized in that signals of various frequency bands can be transmitted and received while maintaining the size of the wireless communication device 10.
The plurality of second input/output ports 220 may be formed at one side of the second antenna housing 210.
The second communication device 200 may be connected to an external apparatus or other wireless communication device 10 using a second input-output port 220.
The plurality of second input-output ports 220 may include an alarm port, an optical port, a power port, and an RTS port, but the present disclosure is not limited thereto.
When the second communication device 200 is installed in the installation space 140 of the first communication device 100, the plurality of second input/output ports 220 and the plurality of first input/output ports 120 may be located on the same surface.
The number of the plurality of second input-output ports 220 may be changed as desired. Preferably, the plurality of second input-output ports 220 may be 4 to 8. The number of second input/output ports 220 of the second communication device 200 may be determined according to the environment in which the wireless communication device 10 is installed.
A plurality of second antenna elements 230 are disposed inside the second antenna housing 210 for transceiving a second signal having a different frequency band from the first signal. Wherein 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 signals of a higher frequency band than the first antenna element 130. For example, the second signal may have a frequency band of 3500MHz to 4000 MHz. Accordingly, a distance D2 between two second antenna elements 230 arranged in the width direction may be smaller than D1. However, the present disclosure is not limited thereto, and the second signal may have other frequency bands in addition thereto. Further, the plurality of second antenna elements 230 are not necessarily arranged in two rows along the length direction at a D1 pitch in the width direction as shown in fig. 1. For example, the plurality of second antenna elements 230 may also be arranged in a row at intervals along the length direction.
Fig. 4 is an exploded perspective view of a wireless communication device according to another embodiment of the present disclosure.
As shown in fig. 4, the installation space 140 may be formed such that the second communication device 200 is inserted from the upper portion of the first communication device 100.
In the case where the first communication device 100 is mounted and a plurality of cables are connected to the plurality of first input/output ports 120, as shown in fig. 4, it is more convenient to insert and mount the second communication device 200 from the upper side in the thickness direction of the first communication device 100.
That is, the second communication device 200 can be mounted without modifying the plurality of cables connected to the plurality of first input/output ports 120 and without stopping the operation of the first communication device 100. The second communication device 200 may be slidably installed and fixed in the installation space 140.
Fig. 5 is a schematic view of the virtual cover of fig. 3 after replacing the second communication device.
Fig. 6 is a schematic diagram of the virtual cover of fig. 4 after replacing the second communication device.
Depending on the installation environment of the wireless communication device 10, when only the first signal frequency is required, there is no need to additionally install the second communication device 200. In this case, the inside of the installation space 140 can be protected from external contamination by the dummy cover 300.
The dummy cover 300 may have a shape corresponding to the shape of the first antenna housing 110 and serves to cover the installation space 140. Fig. 5 illustrates the shape of the dummy cover 300 when the installation space 140 is formed corresponding to the need for the second communication device 200 to be installed in the first communication device 100 in the length direction. Fig. 6 illustrates the shape of the dummy cover 300 when the installation space 140 is formed corresponding to the need for the second communication device 200 to be installed from the upper portion of the first communication device 100. The dummy cover 300 as shown in fig. 5 and 6 has a structure corresponding to the shape of the first antenna housing.
In using the wireless communication device 10 mounted with the dummy cover 300, if the second communication device 200 is additionally provided, the dummy cover 300 may be removed and the second communication device 200 may be mounted. At this time, the operation of the first communication apparatus 100 does not need to be interrupted.
Accordingly, the present disclosure is technically characterized in that it is not necessary to interrupt the currently operating wireless communication apparatus 10 even when the second communication apparatus 200 is added, and the inconvenience of the communication user can be avoided.
The above description is merely for illustrating the technical idea of the present embodiment, and it is possible for those skilled in the art to which the present embodiment pertains to make various modifications and variations without departing from the essential characteristics of the present embodiment. Therefore, the present embodiment is not intended to limit the technical idea of the present embodiment but is intended to be illustrative, and the scope of the technical idea of the present embodiment is not limited by the embodiment. The scope of the present embodiment should be construed based on the following claims, and all technical ideas within the scope equivalent thereto should be construed to be all falling within the scope of the present embodiment.
