1. A method of radio channel allocation in a fixed wireless access communications network, said network comprising:
- (i) a base station;
(ii) a plurality of subscriber stations; and
wherein the base station and the subscriber stations are adapted such that communication between the base station and the subscriber stations is achieved in use, using one of a number of radio channels, each radio channel having different transmission characteristics; and
wherein each radio channel can be transmitted at one of at least two power levels determining a set of suitable radio channels;
said method comprising the steps of;
allocating a radio channel for use in communicating between one of the subscriber stations and the base stations selecting the lowest acceptable power level which provides an adequate signal quality.

Abstract
A fixed wireless access communication network is described. The capacity of a fixed wireless access network is limited by the number of radio frequencies and hence the numberof channels available. The present invention prepares a solution to this problem whenever the radio channels are transmitted at one of at least two power levels.
