Abstract

An apparatus and method of clock synchronization of a powerline modem network for a plurality of devices are provided. A plurality of devices are provided having a powerline modem and a clock (100). The powerline modem permits communication between the plurality of devices over a powerline network. A synchronization message is provided over the powerline network (102). The synchronization message includes an instruction for reach of the plurality of devices to update their clock in accordance with a clock time provided in the synchronization message (104). A synchronization device may be provided to update device clocks on a powerline network.
