초록

A plurality of transceivers (114) each include a transceiver circuit (409), and a processing system (412) coupled to the transceiver circuit. A periodic communication cycle is divided into a plurality of frames, each frame having a predetermined interval. Each of the plurality of frames in turn is subdivided into first and second portions (301, 303), whereby the second portion is used by the transceivers for requesting access to a communication medium (113). The second portion is further subdivided into a plurality of time slots, each time slot having a ...
