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 NJ eFOG mobile app is an electronic reference of the New Jersey Eletronic Field Operations Guide. The NJ eFOG 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 New Jersey and other interoperability channels, tables of frequencies and standard channel names, and other reference material.

The NJ eFOG 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. NJ eFOG can be downloaded and then taken to the field as an offline reference, to be used without the need of an Internet connection.

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