Narrowbanding Guide for Public Safety Compliance

Public Guide to Narrowbanding Compliance The International Association of Fire Chiefs (IAFC) and the International Municipal Signal Association (IMSA) have put together this brochure to provide guidance to state and local public safety entities on requirements being imposed by the Federal Communications Commission (FCC). These requirements are often referred to as narrowbanding.   

Current Statewide Plans

New to Interoperability issues? Need to implement current plans? Here are the most current statewide plans and policies:



Radio Frequency (RF) Over Long-Term Evolution (LTE)/Internet Protocol (IP) Gateway Policy

Wisconsin Recommended Public Safety Radio Channel Naming Standards (April 2017)

Best Practices for LMR Encryption (September 2016)

WISCOM Policies, Procedures and Guidelines (May 2015)

2020 Wisconsin COMU Standard Operating Guidelines

National Interoperability Field Operations Guide (NIFOG)

The National Interoperability Field Operations Guide (NIFOG) is a technical reference for emergency communications planning and for radio technicians responsible for radios that will be used in disaster response. The NIFOG includes rules and regulations for use of nationwide and other interoperability channels, tables of frequencies and standard channel names, and other reference material. It is formatted as a pocket-sized guide for radio technicians to carry with them.

State of Wisconsin Field Operations Guide (WI-FOG)

The State of Wisconsin Field Operations Guide (WI-FOG) is a collection of radio communications technical reference material for emergency responders. This guide was developed with input from various state, local, and federal agencies and is intended to evolve through regular updates and expand as needed. Included within this document are usage guidelines, statewide and national interoperability channels, and Incident Command System references.

Communication Assets and Survey Mapping (CASM)

The Communication Assets Survey and Mapping Tool (CASM), offered by the Cybersecurity and Infrastructure Security Agency (CISA) Interoperable Communications Technical Assistance Program (ICTAP), is the primary resource nationwide for the emergency communications community to inventory and share agency, asset, and Communications Unit information, for the purpose of planning public safety communications operability and interoperability.

In late 2019, the Department of Military Affairs (DMA) Office of Emergency Communications (OEC), in conjunction with the Communications Unit Workgroup (COMU WG), started to develop a CASM Account User Policy for the State of Wisconsin. The purpose of the policy is to define administration, account creation, rules for data entry, and maintenance of information related to CASM for the State of Wisconsin. In July 2020, the Wisconsin CASM Account User Policy 2020 was approved by the Interoperability Council.

Wisconsin CASM Account User Policy 2020

Included in the policy:
  • CASM access application process. You must be a registered user to access CASM.
  • Fact sheet on CASM created by CISA
  • Guidelines for users entering asset and data information into CASM
