CARRIER SENSE MULTIPLE ACCESS (CSMA) FOR NON-PACKETIZED WIRELESS DIGITAL VOICE NETWORKS USING INTELLIGENT CONVERSATION BOUNDARY DETECTION

摘要

A communications system includes a plurality of radios that form a carrier sense multiple access (CSMA) wireless communications network and communicate non-packetized digital voice with each other. Each radio is operative for dividing the period following the end of a transmission into a sequence of time slots and determining whether an end of a conversation has occurred. If an end of a conversation has occurred, the system decides randomly or pseudo-randomly with probability p to start transmitting on the channel in that slot.
