2) In adopting the L-Band Order, the @FCC was informed by its Office of Engineering & Technology staff and their expert analysis. The FCC’s careful decision includes safeguards for GPS + satellite services in adjacent bands: a 23 MHz guard-band, base station power limits, & more.— Seth Cooper (@CooperFSF) July 27, 2021
For more on what's right with the FCC's L-Band Order and what's wrong with the RETAIN Act, see my blog posts from May 26 and July 1 of this year.
4) Flawed RETAIN Act's blanket replacement mandate ignores the fact that some GPS devices receive signals using Ligado's licensed spectrum - far outside the GPS allocation. RETAIN ACT's blanket approach effectively would give third parties rights in Ligado's licensed spectrum.— Seth Cooper (@CooperFSF) July 27, 2021
