Earlier this month, the FCC released a Public Notice announcing that companies that are licensees, or have otherwise registered their fixed C Band satellite earth stations in the 3.7 to 4.2 GHz band, must certify the accuracy of the information on file with the FCC by May 28, 2019. Operators of fixed earth stations who filed registrations last year between April 19 and October 31 using the simplified process that the FCC allowed during that period are exempted from this updating process (see our posts here and here on last year’s window). However, registrants and licensees of transportable or temporary fixed earth stations, including those registered last year, have additional required registration requirements during this same window. These filings will be considered by the Commission in connection with their consideration of expanded uses of this spectrum. So broadcasters with earth stations in this band should familiarize themselves with this new filing requirement, and be sure to file, if required, by the May 28 deadline.
