Abstract: A full duplex infrared wireless communication device is disclosed for use with any of a plurality of electronic devices. The system includes a remote unit and a base. The device is adaptable to be used with any of a plurality of devices, including cellular, portable and landline telephones. The base unit electrically connects with the electronic device to adapt signals from the electronic device for transmitting to the remote unit via a first infrared wavelength. The remote unit transmits signals to the base unit on a second infrared wavelength. When used with a telephone, the remote unit includes a headset with a speaker, a microphone, and data processing circuitry to receive digital signals on the first infrared wavelength and to transmit digital signals on the second infrared wavelength.
