T-Mobile has certainly been making waves with its aggressive moves to ditch wireless contracts and offer more frequent smartphone upgrades. However, there’s one area the company desperately needs to address if it’s going to compete with the big boys at Verizon and AT&T: Its network. Per Reuters, it looks as though T-Mobile is ready to make a bigger push to add more spectrum to its portfolio by pushing a stock offering that it estimates could generate up to $2 billion a year that will be used for spectrum purchases. T-Mobile has also been getting some fresh spectrum from its acquisition of MetroPCS and from AT&T as part of its severance deal after the companies’ failed merger.
