Abstract

Abstract A system and method of forming a network, out of a plurality of mobile communications units sharing a common transmission medium without requiring a base station, are disclosed. Each unit is assumed to have provision for self asserting its own position and has facility for two-way communicating with the other mobile communications units. The method allows that any two mobile communications units, participating in the network i.e., registered to it, eventually acquire the capability of communicating even though the units are not capable of communicating directly e.g., because of the distance between them. Hence, they gain the capability of communicating indirectly through intermediate units of the network acting as relays.
