RADIO COMMUNICATION SYSTEM
In a wireless communication system including a plurality of wireless stations provided in a structure having a radio wave shield arranged at a fixed position, at least one of two wireless stations using an identical wireless channel and two wireless stations using wireless channels adjacent to each other are allocated on both sides of the radio wave shield, respectively. In this case, the structure is an aircraft, and the two wireless stations are allocated on different aisles of the aircraft, respectively. In addition, the two wireless stations are allocated to be apart from each other in a longitudinal direction of the aircraft.
