Abstract
A technique for locating a device uses connectivity to find a distance between an access point (AP) and a device. The AP transmits a frame to a device and receives an acknowledgement frame from the device. The amount of time for a signal to pass between the AP and the device is estimated and multiplied by the speed of light to find the distance between the AP and the device.
