[0010] Hereinafter, some embodiments of the present disclosure will be described in detail 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 addition, when describing the present disclosure, if it is determined that a detailed description of related publicly known configurations or functions would obscure the gist of the present disclosure, the detailed description will be omitted.

[0011] In describing components of the embodiments of the present disclosure, reference numerals such as first, second, 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, order, or sequence of the components. When a certain component is described in the specification as "including" or "having" a certain component, this does not mean that other components are excluded, but that other components may be further included, unless explicitly stated to the contrary.

[0012] In this specification, the horizontal length refers to the length in the direction parallel to the Y axis based on Fig. 1, the vertical length refers to the length in the direction parallel to the Z axis based on Fig. 1, and the thickness refers to the length in the direction parallel to the X axis based on Fig. 1.

[0013] FIG. 1 illustrates a wireless communication device 10 according to one embodiment of the present disclosure.

[0014] Specifically, FIG. 1(a) shows a perspective view of the wireless communication device 10, and FIG. 1(b) shows a rear perspective view of the wireless communication device 10.

[0015] 1( a ) and 1 ( b ), a wireless communication device 10 includes a housing 110 .

[0016] The housing 110 includes a lower case 112 and an upper radome 114 .

[0017] The lower case 112 and the upper radome 114 are connectable to each other and, when connected, define an accommodation space between the lower case 112 and the upper radome 114 .

[0018] The housing 110 accommodates the antenna 120 and the internal boards 12 within the accommodation space, thereby protecting the antenna 120 and the internal boards 12 from external impacts.

[0019] The housing 110 has a shape in which either the horizontal length or the vertical length of the housing 110 is relatively longer than the other.

[0020] For example, the value obtained by dividing the longer of the horizontal length and the vertical length of the housing 110 by the shorter of the horizontal length and the vertical length of the housing 110 is 3.0 or more. Above.

[0021] In one embodiment of the present disclosure, a wireless communication device 10 is configured such that one of the horizontal and vertical lengths of the housing 110 is longer than the other, thereby enabling a storage space with a relatively large cross-sectional area to be secured.

[0022] This allows the multiple internal boards 12 to be arranged along a predetermined direction within the accommodation space of the housing 110, and at the same time, the thickness of the housing 110 can be made relatively thin.

[0023] For example, with the lower case 112 and the upper radome 114 combined, the thickness of the housing 110 is 165 mm or less.

[0024] Therefore, the wireless communication device 10 according to an embodiment of the present disclosure can have a slim case shape overall, which has an aesthetic advantage.

[0025] The width, length and thickness of the housing 110 are 285 mm, 950 mm and 150 mm, respectively, although the present disclosure is not limited thereto.

[0026] Meanwhile, the wireless communication device 10 may further include a plurality of external connection ports 115 and a GPS antenna (not shown).

[0027] A plurality of external connection ports 115 are formed on one side of the housing 110. The wireless communication device 10 is connected to an external device (not shown) or another wireless communication device 10 via the plurality of external connection ports 115.

[0028] The plurality of external connection ports 115 include, but are not limited to, an alarm port, an optical port, a power port, and an RTS port.

[0029] The wireless communication device 10 transmits and receives GPS signals through a GPS antenna (not shown), which is exposed to the outside of the housing 110 for smooth transmission and reception of GPS signals.

[0030] FIG. 2 is an exploded perspective view of a wireless communication device 10 according to an embodiment of the present disclosure.

[0031] Specifically, FIG. 2(a) shows an exploded oblique view of multiple internal boards 12 arranged on a lower case 112, and FIG. 2(b) shows an exploded oblique view of multiple internal boards 12 separated from the lower case 112.

[0032] 2( a ) and 2 ( b ), a wireless communication device 10 includes an antenna 120 and a number of internal substrates 12 .

[0033] The antenna 120 and the multiple internal boards 12 are disposed within the accommodation space of the housing 110 .

[0034] In the wireless communication device 10 according to an embodiment of the present disclosure, the antenna 120 is disposed inside the housing 110, and therefore a separate cable is not required to connect the antenna 120 to the wireless communication device 10. Therefore, by connecting the antenna 120 to the wireless communication device 10 via a cable, it is possible to minimize transmission loss that may occur.

[0035] The antenna 120 is a panel antenna including a plurality of antenna elements 121 and has a plate shape corresponding to the lower case 112 .

[0036] The multiple internal boards 12 are disposed between the antenna 120 and the lower case 112 within the accommodation space. At least one of the multiple internal boards 12 can be connected to the antenna 120, thereby receiving a signal from the antenna 120 and transmitting a signal to the antenna 120.

[0037] Each of the multiple internal boards 12 is arranged along a first direction parallel to one surface of the lower case 112 that faces the multiple internal boards 12. In this specification, the first direction refers to the direction in which the multiple internal boards 12 are arranged. For example, the first direction is parallel to the vertical direction of the housing 110 with reference to FIG. 2.

[0038] A wireless communication device 10 according to one embodiment of the present disclosure has a technical feature in that, rather than stacking multiple internal boards 12, multiple internal boards 12 are arranged in a row along a predetermined direction, thereby enabling the housing 110 to have a thinner thickness.

[0039] This allows the wireless communication device 10 according to the embodiment of the present disclosure to be installed in harmony with the surrounding landscape, thereby providing an aesthetic advantage to the wireless communication device 10 according to the embodiment of the present disclosure.

[0040] While FIG. 2 illustrates the first direction being parallel to the longitudinal direction of the housing 110, the present disclosure is not limited thereto.

[0041] For example, the first direction may be parallel to the lateral direction of the housing 110. In this case, the multiple internal substrates 12 are arranged along the lateral direction of the housing 110.

[0042] The internal substrates 12 are arranged in a line along the first direction, but the present disclosure is not limited thereto. For example, the internal substrates 12 may be arranged in a staggered manner or in a zigzag manner along the first direction.

[0043] Each internal substrate 12 is electrically connected to an adjacent internal substrate 12. In this case, the area of ​​each internal substrate 12 other than the connection area with the adjacent internal substrate 12 does not overlap with the adjacent internal substrate 12.

[0044] Therefore, the wireless communication device 10 according to the embodiment of the present disclosure can minimize the overlapping area between the multiple internal boards 12 and maximize the area of ​​the internal boards 12 exposed to the outside. This allows the heat generated from the multiple internal boards 12 to be dissipated effectively.

[0045] The multiple internal boards 12 include a front end unit 130, a power amplifying unit 140, a digital board 150, and a power supply unit 160. However, the present disclosure is not limited thereto. The multiple internal substrates 12 may include other members.

[0046] The multiple internal boards 12 are arranged in the first direction in the following order: front end portion 130, power amplifier section 140, digital board 150, and power supply section 160.

[0047] Such an arrangement of the internal boards 12 is in accordance with the processing sequence of signals transmitted to and received from the antenna 120. Therefore, such an arrangement of the sequence can minimize electrical connections between each internal board 12 and other internal boards 12 that are not adjacent to it.

[0048] Therefore, the configuration of the circuits for connecting each internal board 12 to other internal boards 12 that are not adjacent to it can be minimized, which simplifies the configuration of the multiple internal boards 12.

[0103] The heat pipe 920 extends longitudinally along a first direction in which the multiple internal substrates 12 are arranged.

[0104] The heat pipe 920 is disposed adjacent to an internal board 12 that generates a relatively large amount of heat among the multiple internal boards 12. For example, the heat pipe 920 is disposed adjacent to the power amplifier 140 that generates a relatively large amount of heat.

[0105] FIG. 10 illustrates a state in which a plurality of wireless communication devices 10 according to an embodiment of the present disclosure are connected via a hybrid cable 1010.

[0106] Specifically, FIG. 10(a) shows a state in which a plurality of wireless communication devices 10 are installed on a pole P, and FIG. 10(b) shows a connection state of the plurality of wireless communication devices 10.

[0107] 10(a), multiple wireless communication devices 10 are installed spaced apart from one another on a pole P. In this case, each housing 110 of the multiple wireless communication devices 10 is connected to one hybrid cable 1010.

In this way, a signal transmitted to one wireless communication device 10 is transmitted to the other wireless communication devices 10 in sequence.

[0115] For example, the first wireless communication device 10A and the second wireless communication device 10B are connected by a first connection cable C1, and the second wireless communication device 10B and the third wireless communication device 10C are connected by a second connection cable C2.

[0116] In this case, one end of the first connection cable C1 is electrically connected to the second cable 1013A of the first wireless communication device 10A, and the other end of the first connection cable C1 is electrically connected to the first cable 1012B of the second wireless communication device 10B.

[0117] Moreover, one end of the second connection cable C2 is electrically connected to the second cable 1013B of the second wireless communication device 10B, and the other end of the second connection cable C2 is electrically connected to the first cable 1012C of the third wireless communication device 10C.

[0118] As a result, a signal first transmitted to the first wireless communication device 10A is transmitted to the second wireless communication device 10B via one cable C1, and the signal transmitted to the second wireless communication device 10B is transmitted to the third wireless communication device 10C via another cable C2.

[0119] On the other hand, a plurality of hybrid cables 1010 branch out from a hybrid box 1020 and connect to the respective housings 110 of a plurality of wireless communication devices 10 .

[0120] In this case, the first connection cable C1 and the second connection cable C2 are housed within the hybrid box 1020.

[0121] The hybrid box 1020 allows multiple hybrid cables 1010 to branch out from one location, thereby minimizing the aesthetic impact of the hybrid cables 1010 on the surrounding landscape.

[0122] Another embodiment of the present disclosure illustrated in Figures 11 and 12 described below differs from the embodiment of the present disclosure illustrated in Figures 1 to 10 in that the wireless communication device does not include an antenna therein. Hereinafter, the description will be focused on the distinguishing features of the other embodiment of the present disclosure, and a repeated description of the configuration substantially the same as that of the embodiment of the present disclosure will be omitted.

[0123] FIG. 11 illustrates a wireless communication device 20 according to another embodiment of the present disclosure.

[0124] Specifically, FIG. 11(a) shows a perspective view of the wireless communication device 20, and FIG. 11(b) shows a rear perspective view of the wireless communication device 20. As shown in FIG.

[0125] 11( a ) and 11 ( b ), the wireless communication device 20 includes a housing 210 .

[0126] The housing 210 includes a lower case 212 and an upper case 214 .

[0127] The lower case 212 and the upper case 214 can be coupled to each other, and when coupled, define an accommodation space between the lower case 212 and the upper case 214 .

[0128] The housing 210 accommodates the multiple internal boards 22 within the accommodation space, thereby protecting the multiple internal boards 22 from external impacts.

[0129] The housing 210 has a shape in which either the horizontal length or the vertical length of the housing 210 is relatively longer than the other.

[0130] For example, the value obtained by dividing the longer of the horizontal length and the vertical length of the housing 210 by the shorter of the horizontal length and the vertical length of the housing 210 is 3.0 or more. do.

[0131] In another embodiment of the present disclosure, a wireless communication device 20 is configured such that either the horizontal or vertical length of the housing 210 is longer than the other, thereby ensuring an accommodation space having a relatively large cross-sectional area.

[0132] This allows the multiple internal boards 22 to be arranged along a predetermined direction within the accommodation space of the housing 210, and at the same time, the thickness of the housing 210 becomes relatively thin.

[0133] Therefore, the wireless communication device 20 according to another embodiment of the present disclosure can have a slim case shape overall, which has an aesthetic advantage.

[0134] Furthermore, the wireless communication device 20 according to the other embodiment of the present disclosure has a technical feature in that it does not include an antenna within the accommodation space of the housing 210. Therefore, the thickness of the housing 210 according to the other embodiment of the present disclosure is thinner.

[0135] For example, in a state where the lower case 212 and the upper case 214 are joined together, the housing 21 0 thickness is 80mm or less.

[0136] The width, length and thickness of the housing 210 are 285 mm, 950 mm and 70 mm, respectively, although the present disclosure is not limited thereto.

[0137] Meanwhile, the wireless communication device 20 may further include an antenna connection port 218, a plurality of external connection ports 215, and a GPS antenna (not shown).

[0138] An antenna connection port 218 may be formed on the housing 210 to interface with an antenna (not shown) located external to the wireless communication device 20 .

[0139] A plurality of external connection ports 215 are formed on one side of the housing 210. The wireless communication device 20 is connected to an external device (not shown) or another wireless communication device 20 via the plurality of external connection ports 215.

[0140] The plurality of external connection ports 215 include an alarm port, an optical port, a power port, and an RTS port, but the present disclosure is not limited thereto.

[0141] The wireless communication device 20 transmits and receives GPS signals through a GPS antenna (not shown), which is exposed to the outside of the housing 210 for smooth transmission and reception of GPS signals.

[0142] FIG. 12 is an exploded perspective view of a wireless communication device 20 according to another embodiment of the present disclosure.

[0143] Specifically, Figure 12(a) shows an exploded oblique view of a state in which multiple internal substrates 22 are arranged on the lower case 212, and Figure 12(b) shows an exploded oblique view of a state in which multiple internal substrates 22 are separated from the lower case 212.

[0144] 12( a ) and 12 ( b ), a wireless communication device 20 includes a number of internal boards 22 .

[0145] The multiple internal boards 22 are disposed within the accommodation space between the upper case 214 and the lower case 212. At least one of the multiple internal boards 22 is connected to an external antenna (not shown) and thereby receives a signal from the antenna and transmits a signal to the antenna.

[0146] Each of the multiple internal boards 22 is arranged along a first direction parallel to one surface of the lower case 212 that faces the multiple internal boards 22. In this specification, the "first direction" refers to the direction in which the multiple internal boards 22 are arranged. For example, the first direction refers to a direction parallel to the vertical direction of the housing 210 with reference to FIG. 12.

[0147] A wireless communication device 20 according to another embodiment of the present disclosure has a technical feature in that, rather than stacking multiple internal boards 22, multiple internal boards 22 are arranged in a row along a predetermined direction, thereby making the housing 210 thinner.

[0148] This allows the wireless communication device 20 according to the other embodiment of the present disclosure to be installed so as to blend in with the surrounding scenery, thereby providing an aesthetic advantage to the wireless communication device 20 according to the other embodiment of the present disclosure.

[0149] It should be noted that although FIG. 12 illustrates that the first direction is parallel to the vertical direction of the housing 210, the present disclosure is not limited thereto.

[0150] For example, the first direction may be parallel to the lateral direction of the housing 210. In this case, the multiple internal substrates 22 are arranged along the lateral direction of the housing 210.

[0151] The internal substrates 22 are arranged in a line along the first direction, but the present disclosure is not limited thereto. For example, the internal substrates 22 may be arranged in a staggered manner or in a zigzag manner along the first direction.

[0152] Each internal substrate 22 is electrically connected to an adjacent internal substrate 22. In this case, the area of ​​each internal substrate 22 other than the connection area with the adjacent internal substrate 22 does not overlap with the adjacent internal substrate 22.

[0153] Therefore, the wireless communication device 20 according to another embodiment of the present disclosure can minimize the overlapping area between the multiple internal boards 22 and maximize the area of ​​the internal boards 22 exposed to the outside. This allows the heat generated from the multiple internal boards 22 to be effectively dissipated.

[0154] The multiple internal boards 22 include a front end portion 230, a power amplifier section 240, a digital board 250, and a power supply section 260. However, the present disclosure is not limited thereto, and the multiple internal boards 22 may include other components.

[0155] The multiple internal boards 22 are arranged in the first direction in the following order: a front end portion 230, a power amplifier section 240, a digital board 250, and a power supply section 260.

[0156] The internal boards 22 are arranged in such a manner that they are arranged in a processing order for signals to be transmitted to and received from the antenna, and therefore, such an order of arrangement can minimize electrical connections between each internal board 22 and other internal boards 22 that are not adjacent to it.

[0157] Therefore, the configuration of the circuits for connecting each internal board 22 to other internal boards 22 that are not adjacent to it can be minimized, thereby making it possible to further simplify the configuration of the multiple internal boards 22.

[0158] The above description is merely an illustrative example of the technical idea of ​​the present embodiment, and various modifications and variations are possible within the scope of the essential characteristics of the present embodiment, if one has ordinary knowledge in the technical field to which the present embodiment belongs. Therefore, the present embodiment is intended to explain, not to limit, the technical idea of ​​the present embodiment, and such an embodiment does not limit the scope of the technical idea of ​​the present embodiment. The scope of protection of the present embodiment should be interpreted according to the claims, and all technical ideas within the equivalent range should be interpreted as being included in the scope of the present embodiment.
