High precision access point to access point synchronization in an indoor position location system

摘要: Methods, systems, and devices are described that provide for high precision synchronization between pairs of APs within a tracking area position location network. These tools techniques may incrementally synchronizing timers oscillators located at respective APs. An AP transmit course frequency timing acquisition signal second utilizes to estimate offset and/or time offset. The subsequent fine which be used accurately adjust the estimated AP. thus synchronize its oscillator(s) timer(s). utilized over multi-hop wireless methods, applicable single- multi-floor systems.
