Abstract:
A cooperative phase tracking system allows access points of a wireless network (e.g., a WiFi network) to use a clock or oscillator that may be different or independent from other access points of the same wireless network. As such, the cooperative phase tracking system eliminates a limitation of using a same clock (or oscillator) among the access points and at the same time may allow more access points to be installed for an associated wireless network to serve a larger area. Moreover, the cooperative phase tracking system may attribute intensive computations of relative phase drifts associated with the access points to a dedicated coordinator, thereby alleviating workload of the access points of the wireless network.
