Abstract

The present invention relates to wireless relay devices which allow a number of separate wireless networks to operate as a single network by linking the separate wireless networks using relays communicating over a power line. This allows the communication power and range of devices in the network to be reduced whilst still allowing distant devices to communicate with each other. This helps to improve throughput and security of the system as well as allowing greater frequency reuse within a given area whilst reducing power consumption of individual devices. The system also provides a method for assisting a user in locating a relay device to maximise the benefit of the invention.
