# §27.2. Permissible communications.

- (a) **Miscellaneous wireless communications services.** Except as provided in paragraph [(b)](#b) or [(d)](#d) of this section and subject to technical and other rules contained in this part, a licensee in the frequency bands specified in [§ 27.5](/cfr/47/27.5.md) may provide any services for which its frequency bands are allocated, as set forth in the non-Federal Government column of the Table of Allocations in [§ 2.106](/cfr/47/2.106.md) of this chapter (column 5).
- (b) **775-776 MHz and 805-806 MHz bands.** Operators in the 775-776 MHz and 805-806 MHz bands may not employ a cellular system architecture. A cellular system architecture is defined, for purposes of this part, as one that consists of many small areas or cells (segmented from a larger geographic service area), each of which uses its own base station, to enable frequencies to be reused at relatively short distances.
- (c) **Satellite DARS.** Satellite digital audio radio service (DARS) may be provided using the 2310-2320 and 2345-2360 MHz bands. Satellite DARS service shall be provided in a manner consistent with [part 25](/cfr/47/part25.md) of this chapter.
- (d) **2000-2020 MHz and 2180-2200 MHz bands.** Operators in the 2000-2020 MHz and 2180-2200 MHz bands may not provide the mobile-satellite service under the provisions of this part; rather, mobile-satellite service shall be provided in a manner consistent with [part 25](/cfr/47/part25.md) of this chapter.
- (e) **716-722 MHz and 722-728 MHz bands.** The 716-722 and 722-728 MHz frequencies may not be used for uplink transmission and must be used only for downlink transmissions.
