1. An electronic communication device comprising:

  • a RF wireless transmitter circuit that is configured to transmit a block of data to another communication device via RF signals transmitted at a first rate;

    a magnetically coupled receiver circuit that is configured to receive a communication control signal from the other communication device via magnetic coupling thereto at a second rate which is less than the first rate, and is configured to respond to the communication control signal by selectively triggering the RF wireless transmitter circuit to transmit another block of data when available for transmission; and

    an inductive charging circuit that is configured to convert magnetic signals received from the other communication device into power, and to supply the power to the RF wireless transmitter circuit,wherein the RF wireless transmitter circuit is further configured to transmit data blocks in RF bursts.
