#### § 74.602 Frequency assignment.

(a) The following frequencies are available for assignment to television pickup, television STL, television relay and television translator relay stations. The band segments 17,700-18,580 and 19,260-19,700 MHz are available for broadcast auxiliary stations as described in [paragraph (g)](/on/2024-09-20/title-47/section-74.602#p-74.602(g)) of this section. The band segment 6425-6525 MHz is available for broadcast auxiliary stations as described in [paragraph (i)](/on/2024-09-20/title-47/section-74.602#p-74.602(i)) of this section. The bands 6875-7125 MHz and 12700-13200 MHz are co-equally shared with stations licensed pursuant to Parts 78 and 101 of the Commission's Rules.

| 1 For fixed stations using Band D Channels, applicants are encouraged to use alternate A and B channels such that adjacent R.F. carriers are spaced 12.5 MHz. As example, a fixed station, relaying several channels, would use A01, B01, A02, B02, A03, etc. | | | | | |
| 2 The band 13.15-13.20 GHz is reserved for television pickup and CARS pickup stations inside a 50 km radius of the 100 television markets delineated in [§ 76.51 of this chapter](/on/2024-09-20/title-47/section-76.51). Outside a 50 km radius of the 100 television markets delineated in [§ 76.51 of this chapter](/on/2024-09-20/title-47/section-76.51), television pickup stations, CARS stations and NGSO FSS gateway earth stations shall operate on a primary co-equal basis. The band 13.20-13.2125 GHz is reserved for television pickup stations on a primary basis and CARS pickup stations on a secondary basis inside a 50 km radius of the 100 television markets delineated in [§ 76.51 of this chapter](/on/2024-09-20/title-47/section-76.51). Outside a 50 km radius of the 100 markets delineated in [§ 76.51 of this chapter](/on/2024-09-20/title-47/section-76.51), television pickup stations and NGSO FSS gateway earth stations shall operate on a co-primary basis, CARS stations shall operate on a secondary basis. Fixed television auxiliary stations licensed pursuant to applications accepted for filing before September 1, 1979, may continue operation on channels in the 13.15-13.25 GHz band, subject to periodic license renewals. NGSO FSS gateway uplink transmissions in the 13.15-13.2125 GHz segment shall be limited to a maximum EIRP of 3.2 dBW towards 0 degrees on the radio horizon. These provisions shall not apply to GSO FSS operations in the 12.75-13.25 GHz band. | | | | | |

(1) Frequencies shown above between 2450 and 2500 MHz in Band A are allocated to accommodate the incidental radiations of industrial, scientific, and medical (ISM) equipment, and stations operating therein must accept any interference that may be caused by the operation of such equipment. Frequencies between 2450 and 2500 MHz are also shared with other communication services and exclusive channel assignments will not be made, nor is the channeling shown above necessarily that which will be employed by such other services.

(2) In the band 2483.5-2500 MHz, no applications for new stations or modification to existing stations to increase the number of transmitters will be accepted. Existing licensees as of July 25, 1985, and licensees whose initial applications were filed on or before July 25, 1985, are grandfathered and their operations are on a co-primary basis with the mobile-satellite and radiodetermination-satellite services, and in the segment 2495-2500 MHz, their operations are also on a co-primary basis with part 27 fixed and mobile except aeronautical mobile service operations.

Licensees declining relocation may continue to use their existing channel plan but must discontinue use of the 1990-2025 MHz band when they indicate to an Emerging Technologies licensee, acting pursuant to [§ 74.690](/on/2024-09-20/title-47/section-74.690) or [§ 78.40 of this chapter](/on/2024-09-20/title-47/section-78.40), that they decline to be relocated.

(4) [Reserved]

(b) Subject to the conditions of [paragraph (a)](/on/2024-09-20/title-47/section-74.602#p-74.602(a)) of this section, frequency assignments will normally be made as requested, provided that the frequency selection provisions of [§ 74.604](/on/2024-09-20/title-47/section-74.604) have been followed and that the frequency requested will cause no interference to existing users in the area. The Commission reserves the right to assign frequencies other than those requested if, in its opinion, such action is warranted.

(c) Fixed link stations will be authorized to operate on one channel only.

(d) Cable Television Relay Service stations may be assigned channels in Band D between 12,700 and 13,200 MHz subject to the condition that no harmful interference is caused to TV STL and TV relay stations authorized at the time of such grants. Similarly, new TV STL and TV relay stations must not cause harmful interference to cable television relay stations authorized at the time of such grants. The use of channels between 12,700 and 13,200 MHz by TV pickup stations is subject to the condition that no harmful interference is caused to Cable Television Relay Service stations, TV STL and TV relay stations, except as provided for in [§ 74.602(a)](/on/2024-09-20/title-47/section-74.602#p-74.602(a)) Note 2. Band D channels are also shared with certain Private Operational Fixed Stations, see [§ 74.638](/on/2024-09-20/title-47/section-74.638).

(e) Communication common carriers in the Local Television Transmission Service (Part 101) may be assigned frequencies available to television broadcast station licensees and broadcast network entities for the purpose of providing service to television broadcast stations and broadcast network entities, respectively.

(f) TV auxiliary stations licensed to low power TV stations and translator relay stations will be assigned on a secondary basis, *i.e.,* subject to the condition that no harmful interference is caused to other TV auxiliary stations assigned to TV broadcast stations, or to cable television relay service stations (CARS) operating between 12,700 and 13,200 MHz. Auxiliary stations licensed to low power TV stations and translator relay stations must accept any interference caused by stations having primary use of TV auxiliary frequencies.

(g) The following frequencies are available for assignment to television STL, television relay stations and television translator relay stations. Stations operating on frequencies in the sub-bands 18.3-18.58 GHz and 19.26-19.3 GHz that were licensed or had applications pending before the Commission as of September 18, 1998 may continue those operations on a shared co-primary basis with other services under [parts 21](/on/2024-09-20/title-47/part-21), [25](/on/2024-09-20/title-47/part-25), [78](/on/2024-09-20/title-47/part-78), and [101 of this chapter](/on/2024-09-20/title-47/part-101). Such stations, however, are subject to relocation by licensees in the fixed-satellite service. Such relocation is subject to the provisions of [§§ 101.85](/on/2024-09-20/title-47/section-101.85) through [101.97 of this chapter](/on/2024-09-20/title-47/section-101.97). No new applications for new licenses will be accepted in the 19.26-19.3 GHz band after June 8, 2000, and no new applications for new licenses will be accepted in the 18.3-18.58 GHz band after November 19, 2002. The provisions of [§ 74.604](/on/2024-09-20/title-47/section-74.604) do not apply to the use of these frequencies. Licensees may use either a two-way link or one or both frequencies of a frequency pair for a one-way link and shall coordinate proposed operations pursuant to procedures required in [§ 101.103(d) of this chapter](/on/2024-09-20/title-47/section-101.103#p-101.103(d)).
