scope:

This Recommendation provides radio-frequency channel arrangements for fixed wireless systems (FWSs) operating in the upper 4 GHz band (4 400-5 000 MHz), which may be used for high- and medium-capacity fixed systems, based on a 10 MHz common pattern. Annexes 1 and 2 provide channel arrangements in line with the main body provisions, with 20, 40, 80 MHz. Annex 3 provides an alternative arrangement with 28 MHz channels. Both co-channel and alternated arrangements are provided as well as information on multi-carrier transmission based on these arrangements.
