System and method for synchronizing timers over wireless networks

摘要

A method of synchronizing timers in a wireless network is described. According to some embodiments, a master timer is sampled at the start time of a first beacon in a first data object and the sampled master timer value is broadcast in a second beacon of a second data object. A slave timer is sampled at the start of the second beacon in the second data object and a value representing the duration of the first data object is subtracted from the sampled slave timer value to determine an updated sampled slave timer value. According to some variations, a difference is determined between the sampled master timer value and the updated sampled slave timer value. The method then uses the difference to synchronize the slave timer to the master timer and to other slaver timers synchronized to the same master timer.
