California Radio Interoperable System (CRIS)

Public Safety Communications
Share This Page


The California Radio Interoperable System (CRIS) provides a statewide public safety, interoperable radio system which allows all participating agencies the ability to communicate seamlessly internally as well as interagency without developing their own systems. Providing a high-degree of 700 MHz radio coverage across the State of California allows first responders to communicate effectively across their typical jurisdictional boundaries during emergencies.

The CRIS vision is to provide:

  • Seamless interoperable communication for greater public safety

  • Improve radio coverage to users including whose radio systems are geographically limited

  • Maximize the use of existing, finite radio spectrum


  • Dedicated “talkgroups” and interop channels
  • Noise reduction
  • Encryption
  • IP backhaul
  • Seamless communication between work groups


PSC is planning, designing, and installing an initial phase of operating system within the California central valley along the major traffic arteries of Highway 99 and Interstate 5. The initial phase will include six (6) strategically located sites to maximize coverage, microwave MPLS backhaul networked to one central core.



  • Coming Soon!


If your agency is interested in becoming a CRIS member, please reach out to the CRIS Engineering Unit for consultation. A system engineer will work with you to determine if CRIS will meet the telecommunications service needs of your agency and guide you through becoming a member. Provided below is the CRIS engineering lead:

If you are experiencing trouble with the system or an outage, call PSC’s Network Operations Center (NOC). A system expert is available to provide assistance 24 hours a day and can be reached at 916-657-9999 or 888-657-6577 (Toll Free).


  • 2010 - System of Systems concept is created as part of the PSC Strategic plan. The idea was to implement a system that interconnects individual public safety systems with one another to facilitate improved interoperability and enhanced coverage. This concept would later lead to the vision for CRIS.

  • 2018 – PSC studies the feasibility of implementing a statewide interoperable radio system designed for public safety. Planning and requirements are documented in the form of a Budget Change Proposal (BCP) to seek funding to implement CRIS.

  • 2019 – PSC is granted funding to implement CRIS. The central California region is selected to pilot CRIS; six sites with microwave backhaul operating on one central core.
