International ClassesH04B 001/00825.69 AbstractA communication protocol for a two way transmission system having at least one first transmitter/receiver device, at least one second transmitter/receiver device and at least one repeater for relaying signals between the first and second devices. The protocol includes the steps of transmitting a first signal comprising a command from the first device, repeating the first signal with each repeater in a respective repeater time slot, receiving the first signal at the second device, transmitting status information from each second device in a respective status time slot, forming a status bit map comprising all status information in the at least one repeater, and transmitting the status bit map with the repeater so that the at least one first device has received the status bit map. Preferably, the transmission system comprises an R.F. communication system. If a plurality of repeaters are employed, the repeaters repeat the transmitted signals in a defined repeater sequence. The repeaters build a bit map of all status information received by the respective repeaters during the repeater sequence. In this way, it is assured that all first and second devices receive those signals intended for the respective devices.Other References
