Abstract
An electronic device for wirelessly tracking the position of a second electronic device is disclosed. The electronic device includes transceiver circuitry and processing circuitry. The transceiver circuitry includes a beacon generator to generate a beacon at a particular frequency and direction. An antenna array transmits the beacon, and receives at least one modulated reflected beacon from the second electronic device. The transceiver circuitry also includes a discriminator to discriminate between received modulated reflected beacons and received reflected interfering beacons. The processing circuitry couples to the transceiver circuitry and tracks the position of the second device based on the modulated reflected beacons.
