Abstract
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.
Claims1
A method for time-of-flight (ToF) positioning in a wireless network, the method comprising:
- transmitting a request frame over a first channel from an initiating station to a responding station;
- receiving a response frame from the responding station over a second channel from the responding station to the initiating station, the response frame comprising first channel information for the first channel;
- the initiating station determining second channel information of the second channel;
- and
- the initiating station determining the ToF positioning at least partially in response to the first channel information and the second channel information.
