Similarly, a gap L2 is formed between the second antenna unit 500 and the second side surface 230 of the front cover 200. The gap L1 and the gap L2 may have the same value or different values. In the present embodiment, the gap L1 and the gap L2 have the same value. Specifically, the gap L1 and the gap L2 are preferably in the range of 0.2 mm or more and 3.0 mm or less, and more preferably in the range of 0.5 mm or more and 2.0 mm or less.

You will receive it. However, in the present embodiment, since the first side surface 220 and the second side surface 230 are not provided with ventilation holes or the like, it is possible to prevent communication deterioration due to the thermal influence of the first antenna unit 400 and the second antenna unit 500. ..
Further, since the bottom surface portion of the first antenna unit 400 is connected to the third concave surface 261 of the front cover 200 and is not in contact with the front cover 200 except for the bottom surface portion of the first antenna unit 400, heat from the front cover 200 is generated. Is suppressed from being transmitted to the first antenna element 410 held by the first antenna unit 400.
Further, a heat insulating space of an air layer is formed between the first antenna unit 400, the first side surface 220 of the front cover 200, and the recess 221. In particular, since the gap L1 and the gap L2 are formed long in the vertical direction and the gap L1 and the gap L2 are open to the indoor side, the air in the gap L1 and the gap L2 convects and moves to the indoor side. 1 It is possible to prevent the antenna element 410 from becoming hot.
Further, the second antenna unit 500 also has the same operation as that of the first antenna unit 400, and thus the description thereof will be omitted.

Further, it can be installed so that the router bridge changeover switch 740 provided on the second side surface 230 of the information communication device 100 can be operated.

As a result, in the information communication device 100, since the router and the bridge can be switched in hardware, it is possible to prevent the communication failure that occurs when the information communication device 100 is controlled by software.
Further, since the first antenna unit 400 and the second antenna unit 500 are partially exposed from the surface of the cover 900, the gas flow can be maintained at the same level as in the room, and the heat influence in the information communication device 100 can be affected. It can be prevented and the deterioration of communication performance can be prevented. In particular, the first antenna element 410 and the second antenna element 510 can benefit from the airflow while being protected by the first antenna holder 420 and the second antenna holder 520. In particular, as described above, the gap L1 and the gap L2 are formed long in the vertical direction, and the gap L1 and the gap L2 are open to the indoor side, so that the air in the gap L1 and the gap L2 is satisfactorily formed in the vertical direction. It will be convected.
