The 600MHz Incentive Auction in the US, which is expected to start in March 2016, is intended to open up broadcast TV radio waves for 4G and 5G wireless services: T-Mobile US Inc. is already considered likely to be successful in the auction. (See Small Carriers Optimistic for 600MHz Auction Sans Sprint.)
Sprint Corp. (NYSE: S) has already said it will sit out the auction. Verizon Wireless has also seemed less than enthusiastic about the 600MHz auction in recent public commentary. (See Sprint Says It Will Sit Out Incentive Auction and Verizon to Start Deploying LTE-U in 2016.)
T-Mobile isn't taking any chances, though: It has asked the FCC to exclude Verizon from 12 reserve markets in the auction.
This is not the first big tower sell-off for T-Mobile: The carrier agreed a $2.4 billion deal to sell off towers to Crown Castle in 2012. (See T-Mobile USA in $2.4B Towers Deal.)
