  • Near-far sensing using frequency swept RSSI
    Patent number: 8270905
    Abstract: A method and apparatus for determining proximity of a headset relative to its base. A plurality of frequency swept RSSI signals are measured and processed to determine a near status or a far status of the headset relative to its base. In one example, a peak RSSI signal is identified in the plurality of frequency swept RSSI signals. The peak RSSI signal is compared to a near/far threshold RSSI value to generate a near status or far status indication.
