Communications system and method
First Claim
1. A communications system, the system comprising:
- a plurality of nodes, each node having;
receiving means for receiving a signal transmitted by wireless transmitting means;
transmitting means for wireless transmission of a signal; and
,means for determining if a signal received by said node includes information for another node and causing a signal including said information to be transmitted by said transmitting means to another node if said received signal includes information for another node;
each node having one or more substantially unidirectional point-to-point wireless transmission links, at least some of the nodes having plural substantially unidirectional point-to-point wireless transmission links, each of said links being to one other node only, and being arranged such that transmission or reception of a signal at any particular frequency by a node takes place on only one link at a time.

Abstract
A communications system (1) includes a plurality of nodes (2). Each node (2) has receiving means for receiving a signal transmitted by wireless transmitting means; transmitting means for wireless transmission of a signal; and, means for determining if a signal received by said node (2) includes information for another node (2) and causing a signal including said information to be transmitted by said transmitting means to another node (2) if said received signal includes information for another node (2). Each node (2) has one or more substantially unidirectional point-to-point wireless transmission links (3). At least some of the nodes (2) have plural substantially unidirectional point-to-point wireless transmission links (3). Each of said links (3) is to one other node only (2). Each node (2) is arranged such that transmission or reception of a signal at any particular frequency by a node (2) takes place on only one link (3) at a time.

29. A method of communications, the method comprising the steps of:
-
(A) transmitting a signal from one node to another node along a substantially unidirectional point-to-point wireless transmission link between said nodes; (B) receiving said signal at said other node; (C) determining in said other node if the signal received by said other node includes information for a further node and transmitting a signal including said information from said other node to a further node along a substantially unidirectional point-to-point wireless transmission link between said nodes if said signal includes information for a further node; and
,(D) repeating steps (A) to (C) until said signal reaches its destination node, wherein transmission or reception of a signal at any particular frequency by a node takes place on only one link at a time. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
