You can have four different radios programmed in, one on each channel. According to Capt. Such flexibility will allow commanders to tailor their communications needs to the tactical environment. If the operation becomes an amphibious assault, the DMR can be switched to very high frequency to communicate with U.S. Marines on the beach. As the Marines move inland, high frequency transmissions are then selected.
Security is a concern because the radios can be remotely reprogrammed over the air.
AIM is a programmable cryptographic engine designed to secure communications applications across a spectrum of encryption levels, from military and government through commercial grades of security. Because AIM is programmable, WITS devices can be sold commercially overseas without Defense Department-unique encryption, satisfying multiple markets, he says. The radio also operated in amplitude modulation and frequency modulation wavelengths across the band, from 2 megahertz to 2 gigahertz, and provided a receive-only function at 100 kilohertz. Kohler adds that all of these functions will be in the units being deployed to the Navy. For channeling data on board Navy ships, the DMR demonstrated SNMP, Ethernet and serial connectivity requirements.
