ALERT --- MABAS Wisconsin based Fire Departments are NOT AUTHORIZED to utilize Fire Ground Green within Wisconsin. This is an unlicensed frequency and will cause radio inteference with agencies that use the frequency in Wisconsin. Those agencies are NOT always Fire Service entities. Please remove this frequency from your radios when narrow banding.

WHAT IS WISCOM ?
System Overview - State of Wisconsin VHF P25 system

Most local emergency responders communicate with responders from neighboring communities by programming their public safety radios with a small number of shared “mutual aid” channels. This approach works well for routine incidents but it doesn't support emergency communications between agencies outside these established networks, resulting in communication failures when coordination is especially critical and time is of the essence

The Wisconsin Interoperable System for Communications (WISCOM) is a shared system that first responders in communities across the state will use to communicate during a major disaster or large-scale incident. WISCOM will support up to four simultaneous conversation paths during an incident, dramatically increasing the current capacity available with statewide mutual aid channels and allowing responders from any area of the state to assist another community without losing communication capabilities.

The WISCOM backbone of more than 80 core sites has been completed. The first phase of the build-out is completed and commissioned April 30, 2012. Four to six more core sites are in the planning stages or under construction at this time. Local buildout of WISCOM in communities and counties who opted to use WISCOM as their daily radio system is currently on going. These buildouts are designed to provide handheld coverage in those communities.

WISCOM overall is built to provide 95 percent mobile coverage from the core sites. This means 95% of the state is covered 95% of the time when using a 50-watt mobile radio. There will be portable radio coverage in many areas of the state as well.

The coverage maps in the links below show anticipated mobile and portable radio coverage from the core sites throughout the state. The active site map shows approximately where the core sites are located and when they are anticipated to be operational.

WISCOM:

  • Leverages existing radio towers and other infrastructure, resulting in less initial cost.
  • Does not use proprietary technology - it is flexible - working with the wide variety of local systems currently operating in the state.
  • Several manufacturers of radios have been certified as WISCOM capable.
  • Shares a statewide infrastructure that will result in long-term cost-savings for everyone. Communities are already spending millions of dollars on systems that do not allow interoperability. As communities replace their aging local systems, they will be able to leverage the state backbone, sharing infrastructure costs and avoiding costly duplication of equipment. Communities can then build out additional local coverage and capacity to meet their needs when they are ready.
  • Is managed by the Statewide System Management Group (SSMG) - including public safety executives from federal, tribal, state, county and local law enforcement, fire, EMS and emergency management disciplines - ensuring that the WISCOM project has input from a variety of potential users and meets the needs of the entire public safety community.
  • Is supported by the Wisconsin State Fire Chiefs Association,the Wisconsin Chiefs of Police Association, Badger Sheriffs Association, and Wisconsin Emergency Management Association.
