发明名称 HIGH PRECISION NETWORK SYNCHRONIZATION IN AN INDOOR POSITION LOCATION SYSTEM
摘要 Methods, systems, and devices for synchronizing a position location network. The methods, systems, and/or devices may provide for designating as a master AP one AP from a network. The master AP may broadcast synchronization signals, which other APs in the network may use to synchronize their respective oscillators and/or clocks. In some cases, the master AP and/or a network server (e.g., a tracking management server) may designate acting master APs. The acting master APs may, for example, broadcast synchronization signals to neighboring APs. The acting master APs and/or the master AP may maintain lists of synchronized APs, which may be transmitted among APs and/or to a network server.
