Abstract

PURPOSE:To increase the repetitive effect of radio frequency, by applying a small zone constituting system to a part of district having concentrated traffic, and a large zone constituting system to other districts. CONSTITUTION:In a district A concentrated with traffic and its surrounding disstricts B, a small zone constituting system in which radio channels not interferred is assigned and allocated fixedly, is applied to each radio zone consisting of small areas having partial width which can sufficiently be communicated within a range of transmission power of mobile stations. In the district A, the use of all the radio channels is possible. Further, in a surrounding district B, it corresponds to a repetitive zone and it plays a role of preventing the electromagnetic wave interference between the district A and other districts except A and B. Further, in other districts except A and B, a large area having the extent including a plurality of radio zones is taken as a unit, and within the unit area, a large zone constitution system in which each radio zone commonly uses a plurality of radio channels, is applied.
