ABSTRACT:
The present invention is directed towards an untethered microphone associated with a radio telephone base and adapted to provide wireless communication therebetween. The remote microphone may include a rechargeable battery and a solar power supply and associated panel configured to recharge the battery. The remote microphone and base unit are adapted to each transmit and receive data and control signals therebetween. The remote microphone is further adapted to transmit voice signals from the microphone to the base unit during operation. Typically, a first transceiver is located with the remote unit, and a second transceiver is located with the hands-free base unit. Working together, the transceivers carry the microphone's signals to the radio telephone's transmitter. Additionally, the transceivers carry call-in-progress information back and forth between the microphone and the hands-free base unit.
