T-Mobile analyzed the 600 MHz locations and channels and decided they could start operating immediately in areas where the TV channels are already vacant, and help broadcasters with the expenses of moving others. They actually started using their new spectrum in Wyoming earlier this year, and are now helping free up the channels in the largest US market, New York City. T-Mobile is also helping several PBS stations make their moves as well.

T-Mobile will help the local TV station in New York that will be moving, move sooner, to make room for T-Mobile to start operating on these new channels in NYC. This is very pro-active on the part of T-Mobile on their path toward becoming a coverage leader in the US. It also helps the TV stations involved get their move done faster and cheaper than would happen by pressing the FCC for their share of auction funds. More coverage is better, but remember, those of us who view TV Over the Air need to 're-tune' our TV's from time to time. Hey, more coverage at the push of a button.
