Abstract
The present invention is a communications protocol which provides for voice and data priority channels in order that both voice and data information have equal opportunity to transmit over a communications network. This is achieved by splitting the 25 millisecond FCC dwell time into two 12.5 millisecond halves, and dedicating one half to voice packets and the other half to data frames. In the voice priority channel, the frequency hopping interval is doubled. Additionally, both channels operate independently, each maintaining independent bidding, data transmission, acknowledgement and retransmission. Pad packets are used to insure voice channel connectivity.
