Wireless and SpaceX Weigh in on 17 GHz Draft Order
While FCC commissioners will vote at their September meeting on allowing non-geostationary satellite use of the 17 GHz band (see 2409040053), nothing in the record supports NGSO operations at up to the ITU power flux density (PFD) limits in the…

17.7-17.8 GHz slice, according to AT&T and Verizon. In a docket 22-273 filing posted Friday, the companies said more measures are needed to ensure protection of incumbent fixed service (FS) operators in the band. NGSO operators have "abdicated their burden" of showing that current and future NGSO, geostationary orbit (GSO) and FS systems can coexist in the slice, they said. AT&T and Verizon urged that the FCC require NGSO applicants seeking to operate in the slice have their PFD threshold capped at a certain level unless they submit an aggregate interference analysis showing they will protect FS when operating at a higher level. Cheering the proposed opening of the 17 GHz band to NGSO operations, SpaceX said there's no need to apply equivalent power flux density limits to the band to protect GSO operators. But the FCC should make clear that any EPFD protections adopted will be subject to the outcome of international efforts to modernize EPFD limits and to the outcome of FCC updates of GSO/NGSO spectrum sharing rules, it said. SpaceX said it met with the offices of all five commissioners. AT&T and Verizon said they met with Space, Wireless, and Consumer and Governmental Affairs bureaus and Office of Engineering and Technology staff.
