In accordance with various example embodiments, a vehicle base station wirelessly communicates data with a remote transceiver circuit. The remote transceiver circuit intermittently transitions a data-receiving circuit of the remote transceiver circuit between on and off states. The vehicle base station intermittently polls the remote transceiver circuit with a series of data packets, at least one of which the data-receiving circuit of the remote transceiver circuit will receive while in the on state. The remote transceiver circuit, upon receiving the data packet, will reset a state counter to enable the remote transceiver circuit to receive a wake-up data packet while operating in the on state; in response, transmitting response data to the vehicle base station. The data communication is carried out to facilitate authentication of the remote transceiver. Exemplary embodiments include a system for passive keyless go and passive keyless entry in a vehicle. |
