“Picture this: A combat fire team fans out on a city block, and each soldier is connected to the rest of the platoon by a radio that provides location data and voice communications. Data and voice push through a sea of communications traffic, filling every available bit of electromagnetic spectrum. Each soldier in the platoon, company and brigade becomes a node on the network…That’s the Defense Department’s vision of a fully networked battlefield, made possible by technologies that DOD already is funding or through independent research and development by communications technology providers. ”

DOD develops radio technologies to overcome spectrum limitations — Defense Systems.
