A method of operating a wireless network with a base station and a plurality of outstations comprising transmitting a broadcast signal from the base station, and, in response to reception of the broadcast signal, transmitting an acknowledgement signal from an outstation; wherein at least some of the outstations serve for relaying of signals for other outstations, wherein an outstation relaying an acknowledgement signal appends to the signal an identifier identifying the relaying outstation, and wherein the base station, upon receipt of an acknowledgement signal, stores any appended identifier(s) for later use in routing signals to the outstation which originated that acknowledgement signal. |
