Claim:
1. A digital enhanced cordless telecommunication (DECT) base station, the DECT base station comprises: a transmitter that is arranged to transmit, at different points of time, downlink transmitted DECT signals to another DECT device that differs from the DECT base station; a receiver that is arranged to receive from the other DECT device downlink reception information indicative of attributes of downlink received DECT signals that were received by the other DECT device as a result of the transmission of the downlink transmitted DECT signals; and a processor that is arranged to process the downlink reception information to detect a motion that affects a reception of the downlink received DECT signals by the other device, the motion is of an object that differs from the DECT base station and the other DECT device; wherein the downlink transmitted DECT signals are DECT beacons; wherein the downlink received DECT signals are received DECT beacons; wherein the attributes of the received DECT beacons relate to intensities of the received DECT beacons; and wherein the processor is arranged to detect the motion by finding that the downlink reception information is indicative of changes of intensities between different received DECT beacons that differ from expected changes of intensities at an absence of motion that affects the reception of the downlink received DECT signals by the other device.
