<p>A wireless communication system comprises a network of nodes 2 connected by point-to-point links 3 using highly directional antennae. Each node determines if a received signal includes information for another node and if so, a signal including the information is transmitted to another node. Information is routed or hopped from node to node until it reaches its destination node. The nodes may be subscriber stations or repeaters. Various network topologies are described including fully interconnected, linear chain, tree, lattice, hypercube and combinations. Multiple paths for signal transmission can be chosen each consisting of an even number of links to maintain synchronisation of transmission and reception between nodes. A copy of the information may be sent on a different path or the information may be split between two paths. Traffic is routed by addresses added at each node or by a central system controller, and may be determined by congestion or node availability. Each link from a node may be associated with one or more time slots for transmission or reception. At least one link of a node may use a different frequency to prevent interference.</p> |
