SYSTEM AND METHOD FOR CHANNEL INFORMATION EXCHANGE FOR TIME OF FLIGHT RANGE DETERMINATION

摘要

A system for time-of-flight (ToF) positioning in an IEEE 802.11 network comprises an initiating station that transmits a request frame over a channel to a responding station for a ToF position measurement. The responding station may respond with an offloading of the channel information, request frame receipt time, and response frame transmit time back to the initiating station to enable the initiating station to calculate the ToF position with respect to the responding station.
