Abstract
A receiver for receiving a radio packet transmitted at a transmission frequency. Reception circuitry is arranged to receive radio signals at a receiving frequency. The reception circuitry includes a phase locked loop arranged to maintain the receiving frequency substantially equal to the transmission frequency; a detector which detects within the received radio signals a pre-defined sequence identifying the beginning of a radio packet; and disabling circuitry which disables the phase locked loop after the receipt of the sequence of radio signals identifying the beginning of a radio packet.
