Abstract:
1. A system for synchronizing clock dividers in a wireless network, comprising: a first plurality of wireless base stations formed into a first cluster; a second plurality of wireless base stations formed into a second cluster; wherein at least a first wireless base station in the first cluster has a wireless communication link to a first wireless base station in the second cluster, and wherein the first wireless base station in the first and second clusters each include a local clock unit having an internal clock divider that is operable to derive frame and burst clocks from a received master clock signal; wherein the first wireless base station in the first cluster is operable to transmit a synchronization pulse to other wireless base stations in the first cluster and to the first wireless base station in the second cluster; wherein the first wireless base station in the second cluster is operable to transmit the synchronization pulse to other wireless base stations in the second cluster; wherein the first wireless base stations are operable to reset the internal clock dividers in response to the synchronization pulse in order to achieve a level of synchronization separate from the synchronization provided by the master clock signal.
