These maps show the U.S. counties where AT&T Inc., Verizon Communications Inc. and T-Mobile USA Inc. have, or will have, low-band frequencies. The signals are considered valuable — much like beachfront property — because they travel longer distances and penetrate buildings better than higher band frequencies. T-Mobile and Sprint Corp. say they need more low-band spectrum to compete with their larger competitors. They want the FCC to limit how much of this spectrum AT&T and Verizon can purchase during an auction next year.
The bright pink areas on the T-Mobile map indicate low-band frequencies the company already owns. The light pink shows areas where T-Mobile has agreed to buy spectrum from Verizon in a deal expected to be finalized this year.
