Over the last two days, staff members and volunteers from IMERT participated in a two day statewide communications exercise dubbed Frozen Prairie 2025; this exercise focused on typical communications that are seen through our state but also alternative means of communications. Typical Starcom21 700/800 mHz, VHF high band and low band, and cellular internet was used but a focus on Satellite internet and HF amateur radio and SHARES/OPSECURE HF radio systems was further tested to be able to communicate if a total system failure.
Multiple agencies from across Illinois took part in the exercise, including the Illinois Law Enforcement Alarm System (ILEAS), Mutual Aid Box Alarm System (MABAS), Illinois Emergency Management Agency (IEMA), Illinois National Guard (ILNG), Civil Air Patrol (CAP), Illinois Telecommunicator Emergency Response Team (IL-TERT), Illinois Department of Public Health (IDPH), and multiple local agencies hosting Unified Command Post (UCP) and Illinois Transportable Emergency Communications System (ITECS) assets.
This was a first for IMERT deploying some of our amateur radio systems and gives us more practice and experience participating in exercises like Frozen Prairie, ensuring stronger preparedness and coordination for real-world incidents.
