5G and IoT Supplement
At MILCOM 2010, we finally saw the Warfighter being connected with vehicles, UAVs, ships, helicopters and other aircraft so that everyone can share information immediately. There is no single point of failure in the network as they can all act as nodes in this network-centric military. Secure, interoperable IP communications are now being realized in many military applications. This year's MILCOM theme, "The Next Decade of Military Communications," addressed the issues with connecting various defense, intelligence and homeland security networks as well as the evolution of communications systems and networks as we move into network-centric operations, as Aerospace Corp.'s President and CEO Wanda Austin pointed out in her welcome message.
One of the major trends at MILCOM 2010 was the leveraging of commercial smartphones for military use to field advanced communications to the field quickly. Billions of dollars are invested in the commercial development of smartphones, so why not use that advanced technology for the military? The commercial market also updates capabilities quickly and cost effectively, so if the commercial smart phone can "plug" into a secure military network, the communications device does not become obsolete after a year or two.
Most of the major players were present, including Boeing, GD, Raytheon, Harris, NGC and Cobham. Lockheed Martin and the Aerospace Corp. were the co-sponsors for the show, and many RF/microwave substrate, component and test/measurement companies were active in the exhibition. Lockheed Martin was showing off its AMR-JTRS and MONAX 3G broadband network. AMR-JTRS provides a secure mobile network allowing rapid connectivity. JTRS provides communications between Warfighters and AMF provides new IP-enabled waveforms that deliver high data throughput and secure internet capability (to 10 Mbps). As JTRS units are deployed to aircraft, vehicles and Warfighters, they can now form ad hoc networks and seamlessly communicate voice and data.
One of the best examples of utilizing commercial smartphones for military applications is Lockheed Martin's MONAX 3G broadband network. MONAX is designed to bring an affordable, 3G broadband network to Warfighters at the first tactical mile and enables the use of smartphones and delivers smartphone data, imagery, video and applications. Lockheed has designed a "brick" device (called a Lynx) that has a battery, antenna and RF circuitry to transmit and receive secure 3G communications to the network that the smartphone just clips into. The device uses standard AES 256 encryption and utilizes different frequencies than commercial networks so as to not interfere with the local communications. The base stations can be put up on towers, but are better used on airborne platforms like balloons where they are quickly deployed over the area and provide wider coverage. Below is a short video demonstration of the MONAX network.
LMC plans to build a library of apps appropriate for the Wargfighter such as mapping programs, video surveillance, facial recognition for identification, battle planning, medical apps to forward injured soldier information ahead to the medical unit and more. This will provide capable communications now while other programs come on line in the future like JTRS and WIN-T. There might be a secure iTunes app store in the future!
