Abstract: A wireless mobile videoconferencing system is provided for video, audio, and data communication that is both two-way and mobile, and in communication with other videoconferencing systems around that world. In particular, a mobile teleconferencing system includes a Very Small Aperture Antenna (VSAT) that is in satellite communication with a Technical Operations Center (TOC), which in turn is connected to the public switched telephone network (PSTN) and the Internet. Additional mobility is gained by a portable teleconferencing system (e.g., rollaway self-powered system, briefcase system) that is in wireless communication with the mobile teleconferencing system. Thus, audio, video, telephone, and data communication can be achieved in locations inaccessible to even a vehicle and without electrical power. The mobile videoconferencing system has applications to telemedicine, distance education, business communication, crisis response (e.g.
