TECHNICAL BRIEF

WiMedia Timing Analysis & Clock Accuracy
Both the WiMedia MAC layer and Wireless USB rely on rigorous timing accuracy for several key
aspects of the protocol behavior including MAS reservations and Next MMC time. In beacon
protocol, devices synchronize using a common Beacon Period Start Time (BPST) and are
required to transmit their beacon within a specific time slot. Beacon slot collisions can occur if a
device’s clock drift causes it to transmit while another device is sending its beacon.

The WiMedia MAC protocol operates in a distributed manner and there is no central entity that
manages device synchronization
