T-Mobile amassed ?unprecedented concentration of spectrum,? AT&T complains

That is more than the low- and mid-band spectrum licensed to Verizon and AT&T combined." Verizon said there is "a high likelihood" of competitive harms being caused by T-Mobile acquiring more spectrum, and it urged the FCC to "reject the arrangements or require T-Mobile to take action to mitigate those harms, including requiring spectrum divestitures."Officially, AT&T said it "takes no position on whether T-Mobile's lease applications were properly accepted by the FCC," but the company said that the FCC "should provide an explanation of why it permitted T-Mobile to further exceed the spectrum screen.""The Commission's failure to issue a written order in a transaction allowing spectrum aggregation in excess of the screen to this degree is highly unusual... "As a company that elected not to participate in the Commission's 600MHz auction and currently touts its massive millimeter-wave spectrum holdings as support for 5G superiority, it is simply disingenuous for Verizon to now complain that T-Mobile's addition of 600MHz spectrum to its portfolio is somehow anticompetitive."Further ReadingVerizon’s new 5G coverage maps show just how sparse the network isT-Mobile also said its expanded spectrum holdings will boost competition for home-Internet service, "as T-Mobile plans to use the leased spectrum to offer sorely needed in-home wireless broadband in competition with Verizon—particularly in rural areas."Verizon had complained about T-Mobile's large holdings of low- and mid-band spectrum in big cities including Los Angeles, Chicago, San Francisco, Baltimore, Philadelphia, Boston, Dallas, Houston, and Atlanta.
