The Arizona Department of Public Safety was faced with the issue of radio interoperability and an ageing infrastructure. Their previous statewide emergency radio communications system could not meet the demands of the DPS since 9/11.
To combat the issue, the DPS developed a long-term strategy to establish radio interoperability. However, the project was quite complex and would require years to complete.
By using 619EI Audio Bridges, Arizona DPS were able to continue to use existing equipment whilst upgrading their infrastructure. See how here.
