Abstract:
1. A method for supporting communication comprising the steps of: coupling one of multiple transducers to a circuit to transmit or receive a magnetic field; adjusting characteristics of the circuit depending on which of the multiple transducers is coupled to the circuit; intermittently adjusting characteristics of the circuit during use based upon feedback to more efficiently transmit or receive over one of the multiple transducers; coupling a first transducer of the multiple transducers to the circuit for transmitting; coupling a second transducer of the multiple transducers to the circuit for receiving; transmitting a signal over the first transducer and receiving the signal over the second transducer; and tuning the first transducer and the circuit for transmitting a magnetic field based on feedback from the second transducer receiving the magnetic field.
