A system and method for communicating between nodes in a communications
network. The network includes nodes that broadcast and receive data
packets over a radio channel. The system includes a distributed trunking
method that distributes the communications between the nodes over
multiple channels. Voice and other data may be broadcast over data
channels, while information regarding the availability of the data
channels is broadcast over a control channel. Access to the control
channel is controlled using a protocol that may include carrier sense
multiple access with collision avoidance (CSMA/CA), time division
multiple access (TDMA) or a hybrid of CSMA/TDMA.
