PURPOSE:To eliminate the influence of same radio channel interference by dividing all radio channels N into (n) groups, using them while being distributed to zones belonging to each radio base means and using the same radio channel only in a zone belonging to radio base means located apart. CONSTITUTION:Service areas are covered with small zones of regular hexagons having the same size in the basic zone building block without a gap, each radio base station exists in the center of each regular hexagon, an area within a unit regular hexagon is the service area by using a nondirectional antenna and there is no overlapped area due to the leakage to adjacent zones. Let the number of radio channels assigned to the system be N and when the N is applied to small zone constitution with a repetitive number (n) and a speech traffic is uniformed to each zone, the radio channels are distributed into N/n(=m) groups and used while being distributed in each radio zone and the same radio channel is used only in a radio zone located apart to eliminate the influence of the same radio channel interference in the system. |
