Portable UHF/VHF modem

Portable UHF/VHF modem

   Radio electronics


Modern war exposes high mobility of the task forces, deep maneuverable raids, dispersed deployments in the areas separated by the enemy, global surveillance and integration of all available communication systems into a single network-centric information space. UA.RPA’s UHF modem fully conforms to the modern trends in military communications. Its all-IP infrastructure solves the issues with system interoperability and provides common convergence. Modem is a good candidate for tactical edge networks which operate under disconnected, intermittent, disturbed and low-bandwidth conditions since its network-based architecture enables self-forming, self-healing networking that ensures reliable communications in a dynamic environment.
