FCC Seeks to Supplement Record on 70/80/90 GHz Bands NPRM

On October 8, 2021, the Wireless Telecommunications Bureau (“Bureau”) released a Public Notice seeking to supplement the record on the 70/80/90 GHz Band NPRM.  A summary of the NPRM is included in the email below.  In the Notice, the Bureau seeks comment on the following:

  • The feasibility of permitting High Altitude Platform Stations (“HAPS”) or other stratospheric-based platform services in the 70/80/90 GHz bands, or portions of the bands, and whether coordination with incumbents is possible.
  • Whether there are international coordination implications with regard to HAPS or other stratospheric-based platform services.
  • If the FCC does authorize HAPS or other stratospheric-based platforms, what service rules should apply.
  • Aeronet’s proposal to permit the use of Scheduled Dynamic Datalinks (“SDDL”), specifically requesting further detailed technical studies demonstrating that deployment of SDDL would not cause harmful interference to incumbents, co-primary users, adjacent band uses or potential future uses of the band, including FS, FSS, HAPS or other stratospheric-based platform services, and the adjacent EESS (passive) and radio astronomy operations.  The Bureau also seeks specific information about anticipated SDDL system operating parameters, including station heights, antenna characteristics, station EIRP, operating bandwidths, and ground station gains.

Comments will be due 30 days after the date of publication in the Federal Register; reply comments will be due 60 days after the date of publication in the Federal Register.
