Abstract:
Methods and apparatus for synchronizing a global time reference for access points over the air are provided. In one aspect, a method for synchronizing a global time of an access point comprises receiving a message comprising a global time indication from a second access point. The method further includes updating the global time of the access point to the global time indication from the second access point by updating a timer of the access point by an increment not to exceed a predetermined value selected small enough to ensure a maintenance of synchronization between the access point and at least one associated wireless station. The global time of the access point is updated to the global time indication from the second access point when the global time indication from the second access point indicated a later global time than the global time of the access point.
