3.45GHz Auction Results January 15, 2022 22:00
On Friday, the FCC posted the results from Auction 110. On Saturday we updated the January 2021 release of our Mobile Carrier - Spectrum Ownership Analysis Tool to reflect the auction results. These results provide the most detailed view of each carrier's spectrum that can be deployed for 5G, particularly all of the available upper mid-band spectrum including EBS/BRS, 3.45GHz, CBRS, and C-band.
In the Spectrum Grid, we can see the channel allocations. In general, Dish took the upper end of the band with T-Mobile and AT&T alternate having the lower parts of the band. In many markets, AT&T is pinned in the middle of the band between T-Mobile, Grain, and Columbia Capital. Each of the spectrum investors has selected spectrum assignments adjacent to AT&T's spectrum meaning they are each well positioned to sell to AT&T if the 3.45GHz spectrum cap is lifted.
In the National Band Ownership slides we look at each carrier's ownership based upon the percent of MHz-POPs that they control.
For the 3.45GHz band, AT&T leads the way with 39% of the MHz-POPs, Dish has 30%, T-Mobile has 12%, and USCellular has 4%.
Looking the the complete picture for Upper Mid-band spectrum, T-Mobile still leads with 34%, Verizon follows with 30%, then AT&T with 24%. Dish has 9% of the upper mid-band MHz-POPs and USCellular has 2%.
