Abstract
A communication system is provided that includes a controller providing a map of information to enable communication with a plurality of nodes. The information includes identification of two separate time slots, one for random access requests when a node initially contacts a controller and another for exclusively assigned access to transmit messages. The map further provides information to enable identification of the nodes and assigns transmission frequencies.
