Radio Relay International, in cooperation with U.S. Army MARS Region 2, will be conducting a joint interoperability exercise from April 15 to May 15, 2022. The exercise will consist of two phases, the first of which is a limited infrastructure test and training phase, and the second of which is a test utilizing RRI/NTS assets through the last mile in selected states. Messages addressed to various emergency services organizations will originate within the Army MARS Region 2 network from which they will be transferred to the RRI Digital Traffic Network for routing to their destination. Replies will return via a similar path. On-line training sessions are also scheduled to familiarize radio operators with the standard radiogram-ICS213 message format. The schedule and links for these training class are referenced in the exercise plan. Radio Relay International operates an international infrastructure of layered communications networks including both manual mode systems as well as a modified hybrid mesh network utilizing high frequency resources. Radio Relay International also conducts periodic disaster communications exercises designed to provide operator training, systematic tests of network resources, and exercising of the National Emergency Communications Response Guidelines.
