Abstract
An infrared (IR) communication device for audible sound communication over an infrared beam. The IR communication device includes an IR receiver, an IR transmitter, a speaker, and a microphone 210. The IR receiver receives the incoming IR beam. The IR transmitter 206 generates the IR output beam. A pair of IR communication devices form an IR communication system with a pair of IR communication channels. Simplex and full duplex IR communication may be provided over one or a pair of IR communication channels.
