NTIA submits the attached letter from the Federal Aviation Administration (FAA) for inclusion in the above-captioned docket involving a waiver request by Ericsson to enable multiband devices for the 3.45 GHz and 3.7 GHz services. NTIA supports the FAA withdrawal of its concerns regarding the waiver, specifically in terms of out-of-band emissions into the 4.2-4.4 GHz band.
NTIA Comments on Considering Expanding Use of the 12.7-13.25 GHz Band for Mobile Broadband or Other Expanded Use
NTIA, on behalf of the Executive Branch and consistent with its responsibility to ensure that the views of the Executive Branch are effectively presented to the Commission, provides these comments in response to the Notice of Inquiry (NOI). There are a variety of federal uses of 12.7-13.25 GHz and adjacent bands, as well as commercial uses that are important to federal missions. NTIA, therefore, is concerned about the potential for harmful in-band and adjacent-band interference if the 12.7-13.25 GHz band (12.7 GHz band) is repurposed as contemplated in the NOI.
