50.2-71 GHz Realignment

In this document we realign allocations in the 50.2-50.4 GHz and 51.4-71 GHz frequency bands. This action continues our efforts to facilitate the commercialization of the "millimeter wave" spectrum. Until recently, commercial use of this spectrum was not economically viable. However, recent technological advances make this spectrum increasingly usable for commercial services and products. Therefore, we have reexamined potential uses of this spectrum and how best it can be allocated to further the public interest. The realignment of allocations that we adopt today will meet current demands for spectrum in this frequency range and is consistent with the international allocation changes the United States sought and obtained at the 1997 World Radiocommunication Conference.
