  • Patent number: 7307651
    Abstract: A roaming videoconferencing (VTC) system incorporates a portable VTC device with client bridge wireless connectivity that couples to the closest access point (AP) assembly with FCC compliant, enhanced range. Use of APs in combination with amplified directional antennas is successfully demonstrated for two-way VTC, even given their generally-known low Effective Isotropic Radiated Power (EIRP) and half-duplex broadcasting. Optional video, audio and data wireless and capabilities are incorporated into the portable VTC device. Facilities that have a connection to Internet or an ISDN public switched telephone network may thus flexibly provide high-quality VTC to widely spaced parts of the facilities, grounds or work site without the inconvenience or expense of placement of ISDN lines.

  • Publication number: 20030231238
    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.
