Letter of Introduction
It is with great enthusiasm that we present to you the updated Wisconsin Interoperability Field Operations Guide (WI-FOG).
This guide is a collection of radio communications technical reference material for emergency responders, which includes information from the Wisconsin Interoperability Council, the American National Standards Institute (ANSI) Channel Naming Standard, and the National Interoperability Field Operations Guide (NIFOG). This iteration was developed with inputs from various state, local, and federal agencies and is intended to evolve through regular updates and expand as needed.
Included within these pages are usage guidelines, statewide and national interoperability channels, and Incident Command System references. Mutual aid frequencies are open to all emergency responders, who are encouraged to program their radios as appropriate and authorized. As always, Federal Communications Commission (FCC) rules and regulations with regards to licensing and operations should be followed. More information on this process can be found at https://wireless.fcc.gov and in the NIFOG at https://www.cisa.gov/safecom/field-operations-guides.
The State of Wisconsin is the designated authorized licensee of all state designated mutual aid and non-Federal National Interoperability Channels. To operate on these frequencies, the licensee (State of Wisconsin) must designate you as a unit of their system, in accordance with FCC rule 90.421. Agencies that desire to program these channels must request authorization from the State Frequency Coordinator.
In cases where use is necessary for the imminent protection of human life and property, authority to transmit is automatic and will be temporary until the emergency has ended.
Contact the State Frequency Coordinator for assistance using the following email link: DOTDSPStatewideFrequencyCoordinator@dot.wi.gov.
We hope this guide becomes an indispensable tool in your day-to-day activities and encourages more efficient and effective use of our limited mutual aid spectrum. Thank you to all that contributed to the development of the WI-FOG.

Chapter 4 Guidelines for Interoperable Radio Communications
Ch. 4.1 USE OF INTEROPERABILITY CHANNELS
All radio transmissions on interoperability channels are for official use only. The radio frequencies may legally be used under the following circumstances:
- The user agency retains an FCC license or a National Telecommunications and Information Administration (NTIA) authorization for these frequencies, or the user is covered by another authorityโs license.
- A โLetter of Authorizationโ is granted by the State Frequency Coordinator allowing an agency to use any interoperability frequencies licensed to the State of Wisconsin. For information, please e-mail DOTDSPStatewideFrequencyCoordinator@dot.wi.gov.
- The FCC or NTIA issues a โSpecial Temporary Authorizationโ (STA) for the use of channels in a particular area/event.
- The use of the frequency is necessary for the IMMEDIATE protection of life or property. When necessary, radio users may use prudent measures beyond the specifics of their license.
Note: The WI-FOG in and of itself does not grant authority to operate on a given radio frequency. Such authority comes in the situations indicated above.
Ch. 4.2 LICENSING OF INTEROPERABILITY CHANNELS
All radio transmitters, both base and mobile, require a current FCC license or a letter of authorization from the licensee before being placed in operation. Before licensing base station on State (non- Federal/National) channels, please contact the State Frequency Coordinator at DOTDSPStatewideFrequencyCoordinator@dot.wi.gov to discuss options.
Ch. 4.3 CHANNEL/TALKGROUP NAMES
To avoid confusion during interoperable communications, standardized channel/talkgroup names should be stated in widely used terms (e.g., โMARC2โ or โVLAW31โ). Channel/talkgroup numbers corresponding to specific physical locations should not be used unless the resource cannot display alphanumeric characters (e.g., โChannel 1โ or โChannel A14โ).
Ch. 4.4 IDENTIFICATION PROCESS
During interoperable communications, units must use their home agency name, unit type, and agency-assigned unit identifier during transmissions (e.g., โSuperior Engine 1โ). These should not be shortened and should include the entire set of letters and/or numbers.
Base stations shall identify themselves by using their agency name along with any other usual identifier.
Ch. 4.5 CHANNEL MONITOR
Personnel should monitor mutual aid channels prior to transmitting to minimize the possibility of interference with communications in progress.
Ch. 4.6 ENCRYPTION
The use of any mutual aid channel for transmission of any encoded, encrypted, or scrambled message is prohibited. However, encryption is allowed on VTAC36DG and VTAC37DG for law enforcement tactical communications using the common encryption code.
Ch. 4.7 OUT-OF-AREA/ITINERANT MOBILES
Base stations are encouraged to monitor mutual aid channels based on their capabilities. Typically, these channels are the only means for personnel traveling outside their normal jurisdiction to obtain assistance or to report traffic collisions, fires, or other hazards.
Ch. 4.8 PRIORITY LEVELS
Statewide interoperability systems are governed by priority levels that must be always respected. Priority is given to disaster and emergency operations, urgent operations, special events, drills, tests, and exercises. When a higher priority use is required, all lower priority traffic yields the frequency in areas where interference could occur.
Check the interoperability system plans for each interoperability channelโs priority levels.
Priority levels for these systems are as follows:
- Priority 1: Disaster and extreme emergency operations for mutual aid and interagency communications.
- Priority 2: Emergency or urgent operations involving immediate protection of life or protection of property.
- Priority 3: Special event control activities, such as a planned event involving the participation of two or more agencies.
- Priority 4: Drills, tests, and exercises.
- Priority 5: Single agency secondary communications.
Ch. 4.9 PLAIN LANGUAGE
All interoperable communications during multi-agency, multi-discipline incidents will be in plain language. Radio codes, acronyms, and abbreviations should not be used as they may cause confusion between agencies. All verbal requests for assistance or backup must state the reason for the request.
- Plain words such as โhelp,โ โassistance,โ and โback-upโ may have different operational meanings to different agencies.
- The words โemergency trafficโ should be used in the context of a life-threatening situation.
- The word โhelpโ should not be used alone unless in the context of a life-threatening situation.
- Requests for assistance or back-up should clarify the reason for the request.
- All verbal requests for assistance or backup should specify the reason(s) for the request and be acknowledged by the receiving station.
Chapter 5 Requests for Communications Resources
Ch. 5.1 COMMUNICATIONS RESOURCE REQUESTS
An agency needing communications resources or support should contact their local dispatch center and emergency management director. If the request cannot be filled locally, the dispatch center should contact the Wisconsin Emergency Hotline (WEH) at 800-943- 0003, Option 2 to make the request.
Resources for planned events should be coordinated with the appropriate agency at least thirty days in advance for any communications asset or resource. If there is an emergency need

Chapter 7 Wisconsin Interoperable System for Communications (WISCOM)
Ch. 7.1 OVERVIEW
The Wisconsin Interoperable System for Communications (WISCOM) is a statewide digital trunked public safety radio system that is available for use by all disciplines. WISCOM enables users to communicate with multiple public safety agencies to engage in routine interoperable communications and coordinate their mutual aid and multi-discipline incident response efforts on a shared communications system utilizing both regional and statewide interoperability talkgroups.
WISCOM is built on a VHF backbone; however, there are several areas that also offer 800 MHz coverage in addition to VHF.
Ch. 7.2 PLAIN LANGUAGE
All interoperable communications during multi-agency, multi-discipline incidents should be in plain language. Radio codes, acronyms, and abbreviations should not be used as they may cause confusion between agencies. All verbal requests for assistance or backup must state the reason for the request.
Ch. 7.3 UNIT IDENTIFICATION
Field units will announce their home agency and unit number, during interoperable communication situations, (e.g., โSuperior Engine 1โ). Specialized unit โtypeโ may also be included if appropriate to the incident or event.
Ch. 7.4 RADIO TESTS
Any station/unit conducting a radio test on a WISCOM talkgroup shall use the following language to avoid any confusion by those monitoring the talkgroup:
โRadio test on [name of talkgroup]. [Agency/Unit Number or radio service] clearโ.
SPECIAL NOTE: The use of xCALLxx talkgroups for routine radio testing is discouraged.
Ch. 7.5 ENCRYPTION
For the purposes of its use with WISCOM, encryption is a process used to electronically encode and decode a voice message with an encryption algorithm using a specific encryption key.
- Except where operational security requirements determine otherwise, channels and talkgroups used for interoperable communications should not be encrypted.
- Encrypted talkgroups used on the WISCOM system must use the AES-256 encryption algorithm.
Ch. 7.6 RADIO OVER IP (ROIP) INTERFACE
Public Safety Broadband is an emerging technology that leverages specially regulated frequencies to provide IP-based data communications designated for use by public safety practitioners and can provide additional capabilities for both voice and data transmissions, especially during critical incidents or disasters.
Public Safety broadband devices or other equipment using cellular data or other wireless data systems providing Radio over IP (RoIP) services should not be considered as mission-critical replacements for P25 voice communications.
Prior coordination with Wisconsin Office of Emergency Communications (OEC) is encouraged before any agency interfaces RoIP to the WISCOM network. OEC can be contacted at interop@wisconsin.gov or by phone at 608.888.5501.

Channel Use Designators
CALL – Used for interoperability calling (hailing) or during a vehicle pursuit or other dynamic emergency incident in which is likely to cross jurisdictional boundaries. NOTE: Every county level radio system will designate a channel/talkgroup as a dedicated Calling (hailing) channel used to establish an initial point of contact for interagency/inter-discipline communications.
DISP – Modifier used to identify the agencyโs primary communications/dispatch channel(s).
FIRE – Used for incident communications by fire services.
IFERN – Used for incident communications by fire services operating under the Mutual Aid Box Alarm System (MABAS).
GTAC – Used for communications between public safety entities and eligible non-government organizations.
LAW – Used for incident communications by law enforcement agencies.
MED – Used for incident communications by emergency medical services.
TAC – Used for communications by any public safety agency. Generally incident-based and not used for wide-area communications.
COMND – Used for interdisciplinary incident command level communications.
TRVL – Used for communications by any public safety eligible entity to coordinate travel when responding to/from an incident outside of an agencyโs own jurisdiction.
COM – Used as common channel for general non-incident specific communications.
PAG – Used for paging system communications.
- All agencies will identify their agencyโs primary communications or dispatch channel either using the modifier โDISPโ or โDISโ or by adding the number โ1โ after the agency identifier.
- Large agencies with multiple dispatching channels should add a number after the modifier as appropriate.
- The remaining characters will be used to indicate a channel number or other appropriate modifier.
- A โDโ for Direct (or talk around) on a simplex (non-repeated) channel.
- A โDGโ for a P25 digital version of a conventional channel, that is also analog, if applicable.
- Other channel modifiers may include the repeater name/location or other unique identifiers based on specific local needs. Agencies may incorporate APCO/NPSTC definitions as part of their channel naming conventions.

Ch. 8.4 STATEWIDE INTEROPERABILITY TALKGROUPS
WISCOM currently has one โcallingโ talkgroup and seven โtacticalโ talkgroups that are available for use in any region of the state. They are:

Ch. 8.4(a) Use of the SCALL/STAC Talkgroups
- The STACx talkgroups are available for routine statewide interoperable communications, mutual aid incidents or planned events.
- The STACx talkgroups can be utilized for communications between field units that are physically located in different regions of the state; when the local RTACxx are not available or the when the nature or the scale of the incident or event dictates their use.
- Incidents will be assigned in the order beginning with STAC2, then STAC3, and so forth.
- Planned Events will be assigned in the order beginning with STAC8, then STAC7 and so forth. A planned event will not be assigned to STAC2, STAC3 or STAC4.
- The incident command agency will notify all WISCOM capable agencies within the region of planned use of the talkgroup prior to the event via a TIME System message or other appropriate method. WISCOM representatives shall also be notified of the planned event usage via email at WISCOMtech@dot.wi.gov to monitor system resources and avoid any talkgroup assignment conflicts.
- Upon completion of the incident or event, the lead communications center shall instruct all involved units to switch to their primary talkpath and resume normal operations.
Ch. 8.5 REGIONAL INTEROPERABILITY TALKGROUPS
There are six separate interoperability regions on WISCOM that match the Wisconsin Emergency Management (WEM) regions. Each region has been assigned one โcallingโ talkgroup and three โtacticalโ talkgroups. The following table shows the talkgroup assignments with the radio display regional identifier suffix. Note that the regional suffix is NOT used during voice transmissions.

Ch. 8.5(a) Use of the RCALLx1 Talkgroups
- RCALLx1 is the designated public safety regional calling and high priority radio traffic talkgroup on WISCOM. It is the initial contact point for all communications in each region.
- RCALLx1 communications are broadcast region-wide, and can be accessed statewide by any mobile, portable, or base radio monitoring/scanning this talkgroup.
- RCALLx1 should be used as the default communication center-to- communication center talkgroup to transmit assistance requests such as vehicle pursuits, injury accidents, officer(s) requesting aid or assistance, bank alarms, robbery in process or other typical emergency radio traffic.
- Based upon the type of console system used by the dispatch center, high priority incidents being transmitted on RCALLx1 may also be patched/simulcast over the centerโs primary channels or talkgroups.
- As a regional โcallingโ talkgroup, all communications centers need to closely monitor RCALLx1 for transmissions from all public safety field personnel who are requesting assistance from a specific county communications center.
- Since RCALLx1 is a calling and high priority radio traffic talkgroup, once it is determined that extended interoperable communications is required, all involved agencies will be directed to move to a specific RTACxx talkgroup. The dispatch center for the agency with incident command shall be responsible for migration to the RTACxx talkgroup and will use the following format for the announcement:
โAttention all units responding to [incident/location], switch to RTACxx for all traffic related to this incident, authority [Agency with incident command], via [lead communications center name if different from the authority].โ
Contact WISCOM at WISCOMtech@dot.wi.gov to monitor system resources and avoid any talkgroup assignment conflicts. - If the nature or scale of the incident or event requires additional talkgroups, then the statewide tactical talkgroups should be utilized.
- Upon completion of the incident or event, the lead communications center shall instruct all involved units to switch to their primary talkgroup (or channel) and resume normal operations. The lead communications center will also announce on RCALLx1 that RTACxx is โavailable for use.โ

Chapter 9 United States/Canada Line A
Ch. 9.1 FCC LINE A
- FCC โLine Aโ regulations, which are meant to protect U.S. and Canadian land mobile operations near the U.S./Canadian border from interference, restricts the use of some statewide licenses held by Wisconsin.
- Line Aโ is an imaginary line within the U.S. that runs across the northern counties of the state of Wisconsin. It approximately follows the 48th Parallel.
- Operation of VHF and 800 MHz National Interoperability channels without additional frequency coordination is limited to mobile or portable radio equipment with an effective radiated power (ERP) of 3 watts or less.

Chapter 10 Interoperability Channels
Ch. 10.1 CHANNEL SELECTION
When identifying and selecting channels and talkgroups to use for an incident or event, it is important to note that there are several factors that should be considered prior to finalizing the communications plan.
- Localized incidents may be able to make better use of locally defined channels or talkgroups reserved for specific localities. Use of local interoperability or mutual aid channels reduces the likelihood of multiple users operating on the same channel or talkgroup.
- Avoid local assignment of Statewide Interoperability Channels and Talkgroups for routine interoperable communications as they are in daily use.
- Channels identified in this chapter with specific discipline usage may be used for other disciplines whenever necessary.
- Use of statewide or national interoperability and mutual aid channels should be coordinated through the WEH hotline at 800- 943-0003, Opt. 2 whenever practicable.
