DARPA’s Strategic Technology Office (STO) is focused on technologies that enable fighting as a network to increase military effectiveness, cost leverage, and adaptability.
DARPA’s Strategic Technology Office (STO) aims to provide the U.S. military lethality using a strategy called Mosaic Warfare: fast, scalable, adaptive joint multi-domain lethality. STO’s areas of interest include: Mosaic Technologies, Mosaic Effect Web Services (EWS), Mosaic Experimentation, and Foundational Strategic Technologies and Systems.
Troops operating in forward locations without telecommunication infrastructure often rely on a mobile ad hoc network (MANET) to communicate and share data. The communication devices troops use on foot or in vehicles double as nodes on the mobile network. A constraint with current MANETs is they can only scale to around 50 nodes before network services become ineffective. For the past 20 years, researchers have unsuccessfully used Internet-based concepts in attempts to significantly scale MANETs.
Squads of Soldiers or Marines on patrol in remote forward locations often don’t have the luxury of quickly sharing current intelligence information and imagery on their mobile devices, because they can’t access a central server. Troops frequently have to wait until they’re back at camp to download the latest updates. In the meantime, mission opportunities may erode because the information needed at the tactical edge isn’t immediately available.
Missions in remote, forward operating locations often suffer from a lack of connectivity to tactical operation centers and access to valuable intelligence, surveillance, and reconnaissance (ISR) data. The assets needed for long-range, high-bandwidth communications capabilities are often unavailable to lower echelons due to theater-wide mission priorities. DARPA’s Mobile Hotspots program aims to help overcome this challenge by developing a reliable, on-demand capability for establishing long-range, high-capacity reachback that is organic to tactical units. The program is building and demonstrating a scalable, mobile millimeter-wave communications backhaul network mounted on small unmanned aerial vehicles (UAVs) and providing a 1 Gb/s capacity.
