The transceiver listens, and optionally transmits, during part of each frame and otherwise sleeps. The receiver unit has a capacitor connected in parallel to the transceiver for supplying the transceiver with current during listening or transmission. A controlled current for controlling current flowing from the power source to the transceiver and the capacitor. The controlled current source has a DC/DC converter with an input connected to the power source and an output voltage connected to the capacitor.
