Distributed positioning mechanism for wireless communication devices
Abstract:
A wireless communication device can determine its position in accordance with a distributed positioning mechanism to minimize bandwidth and power consumption at the wireless communication device. The wireless communication device can detect positioning control messages exchanged between independent pairs of access points in a wireless communication network. The wireless communication device can determine position information associated with each access point of each of the pairs of access points and timing information associated with the pairs of access points based, at least in part, on the detected positioning control messages. The position of the wireless communication device can then be calculated based, at least in part, on the position information and the timing information associated with the pairs of access points.
