Abstract
There is provided a powerline network that includes a number of stations including a central coordinator for coordinating transmissions of each of the stations. The central coordinator includes a system clock and a network timer and is configurable to transmit a number of network timer values. Each of the network timer values can be transmitted by the central coordinator in one of a number of beacons. Each of the other stations is configurable to utilize the network timer values and a corresponding number of local timer values to estimate a frequency error between the system clock and a local clock and an offset between the network timer and a local timer. Each of the other stations is further configurable to utilize the frequency error and the offset to synchronize the local timer to the network timer.
