Voice Interoperability Plan for Emergency Responders (VIPER)

North Carolina has implemented an 800 MHz statewide medical radio system referred to as the “Viper Medical Network” or VMN.

The VMN establishes a digital talk group for each hospital, military hospital, veteran's hospital, mobile hospital and community health center within the state. When radio equipment is deployed for the VMN, any hospital, ambulance or field medical service unit anywhere in the state is able to communicate throughout the system and across the entire state.
