Radio Relay International (RRI), in cooperation
with U.S. Army MARS Region 2, will be conducting a joint interoperability
exercise from April 15 to May 15, 2022. According to RRI Director of Emergency Management
Jim Wades, WB8SIW, the exercise will consist of two phases, starting with a
limited infrastructure test and training phase, followed by a test utilizing
RRI/NTS (ARRL National Traffic System) assets through the last mile in selected
states.
Messages addressed to various emergency service 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 destinations.
Replies will return via a similar path.
RRI operates an international infrastructure of
layered communications networks including both manual mode systems and a hybrid
mesh network utilizing high frequency resources. More information regarding the
exercise and the organization may be found at the RRI website, <www.radio-relay.org>.
