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.
Claims20
A first wireless device comprising:
- one or more processors;
- and
- a non-transitory computer-readable storage medium communicatively coupled to the one or more processors and storing programming instructions for execution by the one or more processors, the programming instructions instructing the one or more processors to perform operations comprising:
- periodically broadcasting outgoing ranging packets on a measurement channel of a wireless network at respective broadcast intervals;
- receiving, on the measurement channel and from a second wireless device, a plurality of incoming ranging data packets at respective receive times;
- and
- calculating, using a three ranging packet exchange with the second wireless device, a range to the second wireless device.
A method to be performed by a first wireless device determining a range to a second wireless device, the method comprising:
- periodically broadcasting outgoing ranging packets on a measurement channel of a wireless network at respective broadcast intervals;
- receiving, on the measurement channel and from the second wireless device, a plurality of incoming ranging data packets at respective receive times;
- and
- calculating, using a three ranging packet exchange with the second wireless device, a range to the second wireless device.
A processor for a first wireless device, the processor comprising:
- circuitry to execute one or more instructions that, when executed, cause the processor to perform operations comprising:
- periodically broadcasting outgoing ranging packets on a measurement channel of a wireless network at respective broadcast intervals;
- receiving, on the measurement channel and from a second wireless device, a plurality of incoming ranging data packets at respective receive times;
- and
- calculating, using a three ranging packet exchange with the second wireless device, a range to the second wireless device.
