Auction for 5G Spectrum
In December 2020, the auction began for spectrum in the 3.7-3.98 GHz range for 5G. It consisted of rounds that lasted several weeks and brought in $80B to the U.S. government, nearly 70% of which was from Verizon. AT&T and T-Mobile made up the rest. Satellite companies agreed to give up spectrum for compensation. See satellite frequency bands, 5G frequency bands and optical bands.
