CA iFOG

Beginning May 2023, this eFOG is available using the Public Safety Library app. Future eFOG updates will be delivered using the Public Safety Library. The standalone eFOG app will no longer be supported.

The CA iFOG mobile app is an electronic reference of the California Interoperability Field Operations Guide. The CA iFOG is a technical reference for emergency communications planning and for radio technicians responsible for radios that will be used in disaster response. It includes rules and regulations for use by the State of California and other interoperability channels, tables of frequencies and standard channel names, and other reference material.

The CA iFOG mobile app gives users easy access to public safety communications information, offering a content index with links for quick jumps to reference sections, tables, figures, or images. The ability to save Favorites and create in-line notes enables personalized access to critical information. CA iFOG can be downloaded and then taken to the field as an offline reference, to be used without the need of an Internet connection.

CA iFOG was developed by the Department of Homeland Security (DHS) Cybersecurity and Infrastructure Security Agency (CISA) under the Interoperable Communications Technical Assistance Program (ICTAP).
