Base Radio Systems
The National Capital Region (NCR) system is the first completely operational Department of Defense (DoD) Land Mobile Radio (LMR) IP-based P25 system to serve the US Army. NCR Phase I provided interoperable mission-critical voice communications with civilian public safety agencies in the NCR region, including greater Washington DC, Maryland, Virginia and Fort Hamilton, NY. The NCR Phase I deployment covered 10 Army bases including the Pentagon.
The NCR Phase II added the US Navy (Naval District Washington, the Naval Academy, among others) along with the US Air Force (Bolling Air Force Base, among others) to the NCR regional system. NCR Phase II provided wide-area communications and convoy operations over a large footprint, and was one of the first tri-service DoD LMR systems.
