Multinational forces, U.S. government agencies and U.S. troops operating together in forward-deployed locations generally have problems communicating—and not just due to language differences. Technical incompatibility between communications systems can hinder information sharing and timely command and control decisions. DARPA’s Mobile Ad hoc Interoperability Network Gateway (MAINGATE) program is helping overcome this technology barrier. The program is nearing completion and plans to transfer the latest version of the system to Army warfighters still engaged in Afghanistan, but who are now focused more on Force Protection as U.S. forces draw down. The MAINGATE system is providing insights into tactical networking of the future, where systems will need more adaptability and capability.

DARPA has awarded a contract for the third and final phase of its Advanced RF Mapping program, known as RadioMap, which seeks to provide real-time awareness of radio spectrum use across frequency, geography and time. Akin to smartphone maps that show color-coded current traffic conditions, RadioMap is developing technology that visually overlays spectrum information on a map enabling rapid frequency deconfliction and maximizing use of available spectrum for communications and intelligence, surveillance and reconnaissance (ISR) systems.

DARPA’s Strategic Technology Office (STO) is hosting a “Sync with STO” event on August 2 - 3, 2017, designed to familiarize attendees with STO’s mission, problem spaces, program managers (PMs), and technology interests. The event aims to facilitate technical discussion between STO PMs and attendees that explore innovative and revolutionary ideas for addressing national security challenges.

DARPA’s Strategic Technology Office (STO) this week unveiled its updated approach to winning or deterring future conflicts during Sync with STO Day, held in Arlington, Virginia. At the event—which attracted about 300 innovators and entrepreneurs, more than half of whom had never worked with DARPA before—STO program managers outlined new areas of interest and held discussions with attendees to explore innovative technology solutions for strategic national security challenges.

There is increasing interest in making broader use of the millimeter wave frequency band for communications on small mobile platforms where narrow antenna beams from small radiating apertures provide enhanced communication security. Today’s millimeter wave systems, however, are not user friendly and are designed to be platform specific, lacking interoperability and are thus reserved for only the most complex platforms. To expand the use of millimeter wave phased-arrays and make them broadly applicable across DoD systems, many technical challenges must be addressed, including wideband frequency coverage, precision beam pointing, user discover and mesh networking.
