Radio access point (RAP) proof of concept demonstration

The functional capabilities of a radio access point (RAP) demonstrated in a live proof of concept field demonstration are described. An overview of the RAP architecture is first given along with a description of the demonstration setup, which included a mobile vehicle and two RAPS, one in a HMMWV (high mobility multipurpose wheeled vehicle) and another in the laboratory. Both voice and video ISDN service were demonstrated from the mobile platform in stationary position and while on the move (OTM). Among the services demonstrated were 4-way audio teleconferencing, video teleconferencing and whiteboarding, and video collection and transmission. Finally, future design enhancements are discussed. We believe this demonstration was the first to show switched wireless mobile multimedia user services and Integrated Services Digital Network (ISDN) services carried over a wireless asynchronous transfer mode (ATM) backbone network.
