Additional Bands for ESIM Get Satellite Support
An FCC proposal to open more bands for earth stations in motion communications with geostationary orbit satellites has sizable support. ESIM operators "have the skill, experience, and incentive to effectively avoid causing interference to other systems," Inmarsat commented in docket…

17-95, posted Tuesday. Comments on the Further NPRM adopted in September (see 1809260029) were due Monday, replies May 8. Also voicing support were Panasonic Avionics, ViaSat and SES/O3b (see here, here and here). Boeing said the FCC also should move toward rulemaking on use of ESIMs in the remaining frequencies allocated for fixed satellite service, including the 10.7-11.7 GHz band, 12.2-12.7 GHz band, additional portions of the 27.5-30 GHz band and throughout the V-band. Hughes said to ensure interference protection, require ESIM operations in the bands covered by the FNPRM to comply with applicable effective isotropic radiated power limits. The Fixed Wireless Communications Coalition said the agency should clarify that fixed service users in the 10.7-10.95, 11.2-11.45, 19.3-19.4 and 19.6-19.7 GHz bands won't need to protect ESIM downlink users from interference. The National Academy of Sciences' Committee on Radio Frequencies said the FCC should ensure the out-of-band emission standard for ESIM downlinks is sufficient to protect radio astronomy service use of the 10.68-10.7 GHz.
