Section 28.2205 – 28.4445 GHz
Harmonisations CEPT/ERC/REC T/R 13-02, ITU-R Rec. F.748-4
Additional information Duplex sub-bands 28.2205–28.4445 GHz and 29.2285–29.4525 GHz for fixed links of IMT networks infrastructure. In these sub-bands is number of rights for use of frequencies limited. Digital modulation. FDD. Channel separation: 28 MHz or 14 MHz. Max. power delivered to antenna feeder of radio equipment +35 dBm. The holders of radio frequencies assignments carry out the national coordination in sub-bands amongst themselves. The Office carries out the international coordination.

Authorisation VO-R/1
Additional information The use is in accordance with RR footnote 5.484A, 5.538 and 5.539. It can used by uncoordinated stations and by stations on mobile platforms ESOMP - Earth Stations on Mobile platforms. ATPC shall be used. The band 27.5-30 GHz can be used in accordance RR 5.539 by feeder links for the broadcasting-satellite service.
Future It is expected extension of the use of the sub-bands 27.5–29.1 GHz and 29.5–30 GHz by Earth stations of non-geostationary satellite networks. The stations can be placed on mobile platforms provided that their utilisation is on the basis of General authorisation.
