Abstract
A method for prioritizing multiple access to a communication channel for the transmission of packets from a plurality of devices on the communication channel. It comprises the steps of once a packet is ready to be transmitted over a communications channel, sensing if a channel is idle, waiting for a predetermined (prioritizing) time after sensing the channel is idle and then transmitting the packet only if the channel is sensed to still be clear at the end of that (prioritizing) time. A scheme is also described for applying an efficient frequency hopping technique to the method for use on congested, shared radio-bands requiring spread spectrum techniques for access to the band.
