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.
Having mission critical technical problems with WISCOM? Immediately call 608-2WISCOM (608-294-7266) for assistance.
The WISCOM backbone of 80 core sites is under construction. Currently 96 sites are on air.The most recent site map may be found here: WISCOM Site Map
WISCOM is being built to a 95/95 mobile coverage standard from the core sites which means when completed, it will cover 95% of the state 95% of the time when using a 50-watt mobile radio.
- Leverages existing radio towers and other infrastructure, resulting in less initial cost.
- Does not use proprietary technology - it will be flexible - working with the wide variety of local systems currently operating in the state.
- 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.
When an agency conducts training, it is required that the trainer fills out the roster provided below with the listed trainee information. This form should be downloaded and filled out electronically, then emailed back to OJA upon completion of the training module. All training information is kept on file at OJA and is available to the SSMG upon demand for inspection.
To maintain the same level of training for all users, OJA asks that the provided materials are not altered in any way by an agency. It is recommended and encouraged that an agency provides supplemental training on agency-specific topics like agency talkgroups, usage policy etc.
Send all completed training rosters, along with any questions or requests for training to: email@example.com
