Digitized signals allow versatile tactical radio units, networked radar systems and wireless command posts.
New very high frequency radios are sharing the airwaves with sensor systems in battlefield networking. Both communications and radar units have become portable enough that they now are mobile nodes in an interlocking information web.
Increased digitization is allowing command networks to move information about a theater of operations like a traffic policeman controls vehicle flow through a busy circle. The same technology is enabling planners to simulate radio networks to improve deployment efficiency and to reduce interference and electronic countermeasure vulnerability.
