The controversy over CBRS band spectrum was contentious, but ultimately it may pale in comparison with what we’re seeing and likely will continue to see with regard to the adjacent C-band. The C-band includes 500 MHz of spectrum between 3.7 and 4.2 GHz that is currently used by satellite providers, at least in some areas—but is suitable for supporting fixed or wireless service, including 5G. The C-band controversy concerns whether the satellite providers should be allowed to sell that spectrum—an approach the satellite companies say would make spectrum available more quickly. Opponents include T-Mobile, which has proposed instead that the spectrum should be auctioned.
