Abstract

A network for wireless transmission of data includes a source access point, a destination device and a plurality of wireless repeaters that provide a transmission link between the source access point and the destination device. The plurality of access points each includes a single transceiver with separate transmitter and receiver sections operable to simultaneously transmit and receive data on different frequency channels. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
