Radio communication system

Abstract

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.

         10 . A wireless communication system comprising a plurality of wireless stations provided in an aircraft having a radio wave shield arranged at a fixed position,
 wherein 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, and respective wireless stations of at least one of the two wireless stations using the identical wireless channel and the two wireless stations using the wireless channels adjacent to each other are allocated at different positions sandwiching a seat group at a center of an airframe of the aircraft, respectively.   
     
     
         11 . The wireless communication system as claimed in  claim 10 ,
 wherein the different positions sandwiching the seat group at the center of the airframe of the aircraft are different aisles of the aircraft, respectively.   
     
     
         12 . The wireless communication system as claimed in  claim 11 ,
 wherein at least one of the two wireless stations using the identical wireless channel and the two wireless stations using the wireless channels adjacent to each other are allocated to be apart from each other in a longitudinal direction of the aircraft.   
     
     
         13 . The wireless communication system as claimed in  claim 11 ,
 wherein at least one of the two wireless stations using the identical wireless channel and the two wireless stations using the wireless channels adjacent to each other are allocated to put a wireless station using a wireless channel belonging to a wireless channel group different from a wireless channel group of the identical wireless channel and the adjacent wireless channels, between the two wireless stations.   
     
     
         14 . The wireless communication system as claimed in  claim 11 ,
 wherein each of the wireless stations includes a radiation pattern having a main beam in a direction substantially parallel to a width direction of the aircraft.   
     
     
         15 . A wireless channel allocation method for use in a wireless communication system including a plurality of wireless stations provided in an aircraft having a radio wave shield arranged at a fixed position, the wireless channel allocation method including the steps of:
 allocating at least one of two wireless stations using an identical wireless channel and two wireless stations using wireless channels adjacent to each other on both sides of the radio wave shield, respectively; and   allocating at least one of the two wireless stations using the identical wireless channel and the two wireless stations using the wireless channels adjacent to each other at different positions sandwiching a seat group at a center of an airframe of the aircraft, respectively.   
     
     
         16 . The wireless channel allocation method as claimed in  claim 15 ,
 wherein the different positions sandwiching the seat group at the center of the airframe of the aircraft are different aisles of the aircraft, respectively, and   wherein the wireless channel allocation method further includes a step of allocating at least one of the two wireless stations using the identical wireless channel and the two wireless stations using the wireless channels adjacent to each other to be apart from each other in a longitudinal direction of the aircraft.   
     
     
         17 . The wireless channel allocation method as claimed in  claim 15 , further including a step of allocating at least one of the two wireless stations using the identical wireless channel and the two wireless stations using the wireless channels adjacent to each other to put a wireless station using a wireless channel belonging to a wireless channel group different from a wireless channel group of the identical wireless channel and the adjacent wireless channels, between the two wireless stations. 
     
     
         18 . The wireless channel allocation method as claimed in  claim 15 ,
 wherein each of the wireless stations includes a radiation pattern having a main beam in a direction substantially parallel to a width direction of the aircraft.
