Abstract
Collision avoidance is maximized by placing collision avoidance scheduling in a central access manager. The central access manager coordinates downlink transmissions of a base site with the uplink transmissions by subscriber units, virtually avoiding collisions of the two types of transmissions. The subscriber units utilize a waiting period prior to transmission of packets to permit the central access manager to maintain the scheduling.
