To extend the range of the network, NAVAIR mounted cellular air nodes on several Marine H1 helicopters, improving the tactical range the Navy needs and helping commanders make quicker and more accurate decisions during vessel boarding operations. Ultimately, using the LTE network will free up satellite bandwidth and could potentially replace multiple radios, cameras and GPS sys- tems currently used for operations. With 4G LTE technology, con- nectivity will no longer be a barrier to intro- ducing mobility to the shipboard enterprise, according to NAVAIR. Speed of data trans- fer, faster network response times, and increased network ca- pacity will enable faster or real-time informa- tion sharing of large files and streaming media and near-time delivery of time-sensitive data. The 4G LTE system has a throughput of 8 megabits/sec, but because of ongoing industry research and development, the Navy forecasts it will be able to take advantage of a throughput of 1 gigabit/sec in the near future. According to NAVAIR, the 4G LTE project will help "close the communications technol- ogy gap," between commercial industry and the Defense Department by leveraging the $30 billion annual research and development in- vestment of the commercial cellular industry. This has allowed the Navy to focus its funds on unique maritime and requirements issues re- quirements, according to NAVAIR. • BY PAUL McCLOSKEY In 2011, pirates operating off the Somali coast turned the area into a war-zone, putting com- mercial ships at high risk for old-fashioned am- bushes at sea. The conflict spurred the Chief of Naval Op- erations to move ahead with a project by the Naval Air Systems Command (NAVAIR) to test ways commercially available, high-bandwidth mobile technology could be used to provide command and control advantages and "situ- ational awareness" to Navy vessels patrolling the area. Working with Oceus Networks, Inc., NAV- AIR equipped the USS Kearsarge and USS San Antonio with 4G Long- Term Evolution (LTE) technologies, including microwave-based wire- less wide-area network (WWAN), to enhance the ships' existing satel- lite-based communications. In addition to voice calling, 4G base sta- tions on the ships gave the Navy and Marines the ability to use Android-based mobile smart- phones to transmit and stream photographs to commanders at sea. "LTE allows the Navy to leverage all of the advantages of smartphones and commercial broadband," said Larry Hollingsworth, NAV- AIR national director for avionics R&D. "NAV- AIR is trying to address a critical requirement for the VBSS [visit, board, search and seizure] mission, but in addition the sailors are already finding the network useful in their day-to-day work. Navy puts 4G net on the high seas NAVAIR's LTE ship-to-ship network allowed the Navy to adapt smartphone and broadband tech for military uses PROJECT AT A GLANCE PROJECT: 4G Long-Term Evolution Ship-to-Ship Communications OFFICE: Naval Air Systems Command Avionics Research and Development TECHNOLOGY USED: Android mobile phones; 4G Long Term Evolution Networking TIME TO IMPLEMENTATION: 16 months BEFORE: Commercial bandwidth outstrips availability from military sources. Satellite technology limits speed and maneuverability of tactical communications at sea and between ships. AFTER: Marines, sailors equipped with Android devices capable of receiving and transmitting tactical video and other images. Provides Navy advantages in situational awareness at sea for military tactical decision makers. Widespread commercial sourcing of LTE enables Navy technology developers to focus on maritime and security challenges. NAVAIR equipped the USS Kearsarge with LTE tech to enhance its satellite communications. GCN JANUARY 2014 • GCN.COM 17
