Abstract
A method for determining the location of a client device in a wireless network having at least a first and a second other network devices each with a known location is disclosed. The first other network device and the second other network device each transmit to the other two messages, and each acknowledges the first message sent by the other. The client device receives these messages, the acknowledgement messages, and respective timing information indicating the actual time when the message and the acknowledgement message were processed by the first and the second other network devices. The client device utilizes the difference between the actual processing times to determine its location. This method allows the location determination to be independent of the accuracy of the time of flight between the first other network device and the second other network device.
