FCC Chair Ajit Pai this week announced a decision on how to auction new radio spectrum for 5G that will be reclaimed from satellite operators. The FCC will conduct a public auction of spectrum licenses, as it has done with most bands used for mobile services to date. A group of satellite operators that currently have rights to the band had been lobbying for permission to conduct their own private auction instead. The spectrum in question is called the C Band, and it's near 4 GHz, a higher frequency than most bands used for mobile networks today, but much lower than the mmWave bands that some carriers have deployed for 5G in the US. The part of the C Band that is planned to be auctioned for 5G in the US is 280 MHz wide, spanning 3.7 GHz – 4.2 GHz.
