12 GHz NPRM Seeks Input on Interference Protections, Terrestrial Rights
The 12 GHz NPRM adopted last week (see 2101130067) and released Friday has the FCC considering two potential future uses of the band: increased terrestrial use of the shared band, or the status quo framework that sees it allocated on…

a primary basis for direct broadcast satellite, fixed satellite service (FSS) and fixed service. The agency asked in the NPRM about such issues as the technical parameters that could allow additional terrestrial use of the band without harmful interference to incumbents, including whether existing multichannel video and data distribution service criteria would protect non-geostationary orbit FSS from interference from higher-power two-way mobile operations. Noting arguments that NGSO FSS isn't dependent on the 12 GHz band, the FCC sought comment on those views "but reiterate[s] that we are focused on protecting incumbent licensees, including incumbent NGSO operators, from harmful interference in this proceeding." It asked whether the indoor 12 GHz unlicensed devices would be a suitable option for the need for enterprise IoT devices in locations such as confined geographic areas, buildings and campuses. It sought comment on three options for authorizing terrestrial service rights: modifying the licenses of existing licensees or auctioning either overlay or underlay licenses in the band.
