Communications system and method.

摘要

A communications system (1) has a plurality of nodes (2). Each node (2) has a receiver (10) for receiving a signal transmitted by wireless transmitting means and a transmitter (11) for wireless transmission of a signal. each node (2) further has means for determining if a signal received by said node (2) includes information for another node and causing a signal including said information to be transmitted by said transmitting means to another node if said signal includes information for another node. Each node (2) has a substantially unidirectional point-to-point wireless transmission link (3) to at least one other node. The communications system (1) has high spectral efficiency compared to a broadcast cellular system and allows high data transfer rates to be achieved.
