NTIA VHF/UHF Public Safety Interoperability Plan
The National Telecommunications and Information Administration (NTIA) has specified forty (40) Federal Government frequencies that can be used by non-Federal government public safety entities for communications involving coordination and cooperation with Federal Government agencies. These frequencies may not be used to meet the day-to-day communications needs of non-Federal government, public safety entities. Due to previous frequency authorizations to Federal Government agencies, not all channels are available at all locations. The rules governing the use of these frequencies are set forth in Section 4.3.16 of the NTIA Manual of Regulations and Procedures for Federal Radio Frequency Management. (See the NTIA web page)
LAW ENFORCEMENT PLANS
1. Frequencies 167.0875 MHz and 414.0375 MHz are designated as National Calling Channels for initial contact and will be identified in the radio as indicated in paragraph 2 below. Initial contact communications will be established using analog FM emission (11KF3E). The agency in control of the incident will assign specific operational channels as required for incident support operations.
2. The interoperability frequencies will be identified in mobile and portable radios as follows with Continuous Tone-Controlled Squelch Systems (CTCSS) frequency 167.9 Hz and/or Network Access Code (NAC) $68F:
3. All applications using these allotted frequencies shall be affixed with Record Note Sxxx - This assignment is for a joint law enforcement requirement pursuant to Section 4.3.X of this Manual.
CONDITIONS FOR USE
1. The frequencies shown in this plan are available for assignment to all Government agencies to satisfy intermittent law enforcement and public safety incident response requirements. Non-Government agencies may use these frequencies only in cooperation with agencies of the Federal Government. Federal agencies will provide written certification to non-Government agencies indicating that the non-Government operation is necessary. Non-Government entities will be advised in the written certification that under Federal law they are required to obtain a license from the Federal Communications Commission (FCC) for such operations, and that the FCC File Number for the license, once obtained, will be provided to the Government agency providing the written certification. A copy of this certification will also be submitted to the NTIA Public Safety Program Office. Federal agencies shall comply with the requirements of Section 2.3.12 of this Manual. The frequencies are available on a shared basis and will not be authorized for the exclusive use of any one agency.
2. All Government operations shall be authorized in accordance with Chapter 9 of this Manual. The FCC will submit all non-Government applications to the Frequency Assignment Subcommittee (FAS) for approval.
3. Base stations are authorized use of the mobile transmit frequencies for access to fixed stations, e.g., repeaters. Mobile stations are permitted to use fixed station transmit frequencies for talk-around communications.
4. The following restrictions apply:
(a) the minimum ERP necessary to support the intended use shall be employed;
(b) the maximum base or mobile transmitter output power shall not exceed 125 Watts; and
(c) the gain of the base station antenna shall not exceed 6 dBi.
5. Exceptions to the above restrictions will be considered by the FAS on a case-by-case basis.
INCIDENT RESPONSE PLANS
1. Frequencies 169.5375 MHz, paired with 164.7125 MHz, and 410.2375 MHz, paired with 419.2375 MHz, are designated as the calling channels for initial contact and will be identified in the radio as indicated in paragraph 2. Initial contact will be established using analog FM emission (11KF3E). CTCSS will not be used on the calling channels to ensure access by stations from outside the normal area of operation. The agency in control of the incident will assign specific operational channels as required for incident support operations.
2. The Interoperability frequencies will be identified in mobile and portable radios as follows:
3. All applications using these allotted frequencies shall be affixed with Record Note Sxxx - This assignment is for a joint incident response requirement pursuant to Section 4.3.X of this Manual.
