Abstract
In a multicellular communications network system comprising base stations and a plurality of remote stations, a remote station listens for frames of information emitted by the different base or remote stations, in order to insert the network. The base stations and the remote stations comprise means for emitting the frames of information using a sequence of changing frequency hops of different operating frequencies. The remote station determines a set of "n" operating frequencies (Fi), from which it sequentially listens for a fixed period of time equal to 1/n of the frequency hopping period (FH) of a base station. When a frame of information is received by the remote station during one of the fixed period, the information is collected and processed in order to select the base station for attachment.
