Abstract
A transceiver for a packet radio network comprises a plurality of independently tunable receivers (RX1-RX4) and a single transmitter (TX) tunable to the frequencies of the receivers. Messages on different frequencies of the network can thus be simultaneously received by respective receivers, increasing message handling capacity; additionally or alternatively, one or more of the receivers can be used as an auxiliary channel for one or more functions other than standard reception of data packets. Three auxiliary channel modes are described: Voice Net mode for direct voice communication, Time Division Multiplex Repeater mode for a long-range voice link or bulk data transfer to a single destination, and inter-network gateway mode for transmitting messages to an adjacent network.
