<p>A passive transponder (TA) gets its power (P) from a base station's (BS) carrier wave (CW). The transponder can fit in a motor vehicle's/car's door lock and the base station in a car. The base station has a first integrated circuit (IC1) to control a first transmitter/receiver (SE1) with first transmitter (SXT1) and receiver (RXT1) parts. The BS emits a modulated CW for transferring data (D). An independent claim is also included for a device for transferring data by means of an electromagnetic wave, onto which data packets are modulated from different symbols, with a base station and a remote unit like a transponder or a remote sensor.</p> |
