Radio spectrum

Spectrum Work Group

Key roles and responsibilities:

  • Frequency policy and planning
  • Frequency coordination and interference mitigation
  • FCC licensing and compliance

Radio Spectrum Policy and Planning:

The Spectrum Working Group provides advice on spectrum issues, management of the radio spectrum and will plan for the best usage of the radio spectrum in line with Public Safety goals. Priorities for the Spectrum Working Group include providing advice on allocation of radio spectrum for WyoLink and Wyoming Public Safety agencies. The Spectrum Working Group is responsible for planning the allocation of the radio spectrum resource, with the following areas of focus:

  • providing efficient and effective spectrum plans to the FCC
  • forecasting the impact of new and future technology on spectrum
  • providing expert technical advice to other Public Safety Communications Commission working groups
  • managing the process for the allocation of Public Safety radio spectrum
  • representing Wyoming Public Safety radio spectrum interests in regional and national forums such as Safecom and APCO

Radio Spectrum Coordination and Licensing:

The Spectrum Working Group is responsible for coordinating the Public Safety radio spectrum use with all Public Safety agencies, including issuance of Radio Spectrum Memoranda of Understanding for WyoLink and Public Safety agency frequencies.

Radio Spectrum Interference and Compliance:

The Spectrum Working Group monitors the compliance to FCC licenses issued in the Public Safety radio spectrum and advises on the elimination of interference in the Public Safety radio spectrum.

FCC SIEC and Regional Planning Committee mandates:

To comply with the FCC mandate the full Public Safety Communications Commission acts as the Statewide Interoperability Executive Committee (SIEC) with the Spectrum Working Group providing working level support. The Spectrum Working Group acts as the Regional Planning Committees (RPCs) under the direction of the Public Safety Communications Commission.

PSCC Spectrum Work Group

Provide overall planning, policy, coordination, and implementation necessary to ensure adequate frequency spectrum in support of Wyoming's Public Safety Agencies' present and future program goals.

Spectrum Work Areas

The Spectrum Work Group was split into the following three areas. A Subject Matter Expert (SME) was assigned to each of the three areas to address its inherent issues.

VHF Regional Planning

In 2004, the Wyoming Department of Transportation was tasked with developing a VHF Trunk Frequency Plan and licensing those frequencies for WyoLink. Also in 2004, the National Association of Regional Planning Committees made a recommendation to study the feasibility of implementing a VHF Regional Band plan for public safety use similar to the plan used in Missouri.

700 MHz Region 46 Planning Committee

In 1998, the Federal Communications Commission (FCC) adopted a plan for the 700 MHz public safety band, which encouraged the creation of Regional Planning Committees (RPCs) to develop a 700 MHz regional band plan that would provide maximum flexibility to meet state and local needs. In 2001, the FCC decided that states should be responsible for the administration of the 700 MHz interoperability channels. The states had a choice to form a State Interoperability Executive Committee (SIEC) or have the RPC manage the 700 MHz interoperability channels. Wyoming decided to let the RPC manage the 700 MHz interoperability channels. In 2003, the FCC authorized the use of the 4.9 GHz band for public safety use. The FCC also ruled that RPC may submit a 4.9 GHz regional band plan.

800 MHz Region 46 Planning Committee

In 1983, the Federal Communications Commission (FCC) developed a policy to manage the newly allocated 800 MHz public safety spectrum. This policy partitioned the country into regions, roughly corresponding to state borders, which would manage the 800 MHz public safety spectrum. as a result of this policy Wyoming became FCC Region 46. In 1989, the FCC required the regions to form 800 MHz Regional Planning Committees (RPCs) to develop and submit a plan for the utilization of the 800 MHz public safety spectrum. Wyoming Region 46 RPC submitted their plan in 1990.
