Harris Corporation Completes Latest Round of Mobile Ad-Hoc Networking Technology (MANET) Field Testing ATLANTIC CITY, N.J., Sept. 22 /PRNewswire-FirstCall/ -- Harris Corporation (NYSE:HRS) today announced the completion of a third successful field demonstration test validating its open-architecture, Mobile Ad-hoc Networking (MANET) waveform. MANET techniques are critical to the success of emerging modern warfare concepts and are required to support communications for mobile military platforms, including ships, aircraft and ground vehicles operating in a highly dynamic and mobile tactical communications network without fixed infrastructure. The announcement was made during the 2004 Network Centric Ops Conference and Expo (Harris Booth #522), held September 21-23 at the Atlantic City Convention Center. Much of the focus during the June 2004 demonstrations involved testing of user applications operating over the MANET topology. Voice over Internet Protocol (VoIP) conferencing, streaming video, collaborative planning, email messaging and location data reporting were successfully demonstrated. Other testing focused on network self-organization and self-healing as nodes enter and exit the network; link recovery from failures due to terrain-induced blockage; frequency reuse to improve bandwidth; and adaptive channel capacity management to dynamically meet changes in node traffic. The Harris-developed communications waveform was utilized to adaptively schedule seamless link connections between multiple nodes operating in a mobile ad hoc network. The waveform enables directional antennas to form an on-the-move mesh network topology to meet aggregate traffic demands of the battlespace of the future. The field demonstration tested 15 network nodes, 14 mobile nodes and one fixed node to provide a quantitative measurement of network performance under conditions of extreme mobility and terrain-induced link blockages from buildings and dense foliage. The intent was to create realistic operational conditions that result in frequent changes to the communications link and network routing state in order to measure the ability of the system to dynamically adapt. "Untethering military commanders from their static command and control platforms of the past by providing them with robust and dynamically adaptable communications on-the-move capabilities is essential to the fundamental tenets of net-centric warfare," said Rich Folio, director, Technology and Internal Research and Development (IR&D), Harris Corporation's Government Communications Systems Division (GCSD). "The successes of our MANET program and Harris' continued commitment to MANET technology development are critical to the transformational communications initiatives of the Department of Defense." Under a three-year contract with the U.S. Naval Research Laboratory (NRL) sponsored by the Office of Naval Research (ONR), Harris developed state-of- the-art technologies for controlling a network of mobile nodes utilizing directional antennas. Completed under a continuing Harris MANET IR&D effort, the most recent round of field demonstration testing builds upon the numerous successes of the August and December 2003 customer-funded field demonstration tests. Harris is continuing its MANET technology development and has additional field testing demonstrations planned for the near future. Harris GCSD, one of four divisions within Harris Corporation, conducts advanced research studies, develops prototypes, and produces and supports state-of-the-art, assured communications(TM) solutions and information systems that solve the mission-critical challenges of its military and government customers, while serving as the technology base for the company's diverse commercial businesses. Harris Corporation, which also provides tactical radio, microwave, broadcast and network products and systems, serves customers in more than 150 countries.
