Abstract:
1. A method of controlling channel access in preparation for transmitting a data packet in a communications system, the method comprising: electronically providing the data packet to a communications queue; electronically determining a priority of the data packet; electronically generating a channel occupancy statistic, the channel occupancy statistic being related to the number of transmissions presented to a channel; electronically comparing the channel occupancy statistic to a predetermined threshold to determine whether to transmit the data packet; wherein the predetermined threshold is based on the priority of the data packet; and transmitting or delaying the data packet based on the comparison of the channel occupancy statistic to the predetermined threshold; wherein the channel occupancy statistic is based upon the number of pulses received on the channel having an embedded synchronization pattern matching a transmission security derived synchronization pattern.
