T-Mobile dominated the 2.5 GHz frequency auction to fix network gaps across the U.S.

With winning bids totaling $304.3 million, T-Mobile was able to buy 7,156 licenses out of the total 7,872 that were available. Rural regions hold the majority of the 2.5 GHz band’s accessible spectrum.

Three blocks of spectrum, totaling 117.5MHz in each county, were made available through the auction. Overall, 63 bids were successful, and the sale brought in $427.8 million. No-one-has-acquired 2.5 GHz licenses that were put up for auction by the FCC. T-Mobile, which already owns or rents a large portion of the spectrum, won’t have an issue with that.

To decide whether to bid, AT&T and Verizon wanted further details about leasing arrangements. The proposal was turned down by the FCC because it went “beyond the confines of the existing spectrum leasing guidelines.”
