ABSTRACT:
In a communication system using frequency hopping to transmit data packets, a transmission request from a transmitter is transmitted through a first control channel. The transmission request includes a frequency channel designation selecting one of plural data channels. A receiver that receives the transmission request sends a receive confirmation through a second control channel and the data packets are then transmitted through the data channels so that the data channel is changed each time a data packet is transmitted.
