Abstract
Disclosed are methods, systems, and computer-readable medium to perform operations comprising periodically broadcasting, by a first wireless device, outgoing ranging packets on a measurement channel of a wireless network; receiving, by the first wireless device on the measurement channel and from a second wireless device, a plurality of incoming ranging data packets; and calculating, by the first wireless device and using a three ranging packet exchange with the second wireless device, a range to the second wireless device.
Claims21
1-20. (canceled)
A wireless device comprising:
- one or more processors configured to cause the wireless device to perform operations comprising:
- accessing a measurement channel of a wireless network for a predetermined measurement period;
- during the measurement period:
- periodically broadcasting to a plurality of neighboring devices outgoing ranging packets at respective broadcast intervals;
- and
- receiving, on the measurement channel and from the plurality of neighboring devices, a plurality of incoming ranging data packets at respective receive times;
- and
- calculating, using a three ranging packet exchange with a first neighboring device of the plurality of neighboring devices, a range to the first neighboring device.
A method to be performed by a wireless device, the method comprising:
- accessing a measurement channel of a wireless network for a predetermined measurement period;
