T-Mobile told the FCC last week that it wants to modify its experimental authorization so that it can continue to conduct 3.45 GHz tests in the Seattle area, but it’s no longer interested in doing 3.45 GHz tests in the Dallas, New York City or Kansas City, Missouri, markets where it was previously authorized.
The 3.45 GHz auction closed at the end of 2021 after grossing $21.8 billion. AT&T was the big winner in that auction, taking home 1,624 licenses in 406 licenses areas known as Partial Economic Areas (PEAs). T-Mobile won 199 licenses in 79 PEAs.
