This project involves the development of a wireless headset system. The system is an application of digital, audio-encoding, packet switching, local area networking, and time-address multiplexing techniques to form a network of personal headsets. This innovation would allow many headsets on the same carrier frequency to operate from a single base-unit or repeater with software controllable cross-talk, audio mixing, and channel selection. Information on the network may be encrypted.During Phase I, an architecture for a wireless headset network was investigated. This demonstrated the feasibility of supporting a number of wireless headsets linked to a network. Phase I results showed voice coding at both 15,625 bits per second and 31,250 bits per second, packetizing of this data, and communication of this data across a two million bit per second data link. Other digital data can be transmitted simultaneously with full duplex voice. As a result of Phase I, concept feasibility has been proven and supporting up to fifty fully digital headsets from a single base-station was shown to be possible.Potential Commercial Application:Application of this innovation can be found in command, control, and communications, fire-fighters and rescue workers, security systems, sports helmets, and law enforcement.STATUS: Project Proceded to Phase II
