Abstract: A TDMA-based communication method for enabling communication between a base station and a client, the base station and the client each comprising a clock for synchronizing communications, the method comprising: allocating a TDMA channel to said client; causing a transceiver of the client to operate in a communication mode during client timeslots making up said allocated channel and to operate in a sleep mode at other times; causing a transceiver of said base station to begin operating in a communication mode with said client on said channel in advance of each said client timeslot and/or to continue operating in a communication mode with said client after each said client timeslot.

Abstract: According to a first aspect of the present invention there is provided a method for enabling two or more TDMA-based wireless networks to share a communication channel, each wireless network implementing superframes. The method comprises within each network, implementing active superframes separated by one or more inactive superframes and only implementing active superframes when the other networks are implementing inactive superframes, wherein a network only communicates during that networks active superframes and does not communicate during that networks inactive superframes.
