California Interoperable Communications

Interoperability is the ability for emergency responders to communicate among jurisdictions, disciplines, and levels of government, using a variety of frequency bands, as needed and as authorized.

While interoperability is easy to define, implementing radio interoperability statewide involves the cooperation and collaboration with agencies and groups throughout the entire state of California. We achieve this cooperation and collaboration through a number or key committees and individuals. Successful interoperability in California relies on the collaborative interaction between a number of agencies at all levels throughout the state.


​Interoperable Communications Planning


California Statewide Interoperability Executive Committee (CalSIEC) is tasked with managing the interoperability spectrum and developing governance on behalf of all California public safety emergency responders. The CalSIEC consists of the planning chair / co-chairs from each of the CalSIEC Planning areas. Each Planning area has established a governance structure for interoperable communications that is comprised of emergency responders and public safety agencies from all public safety responders in the operational areas to include state agencies.
