AT&T is already struggling to provide enough airwaves to meet consumer demand, and gaining access to T-Mobile's airwaves was one of its main reasons for trying to buy the company.
But the transfer will be a boost for T-Mobile, which is working to expand its network.
“We applaud the FCC for acting swiftly to approve the transfer of these spectrum licenses,” said Neville Ray, T-Mobile's chief technology officer. “Securing this additional spectrum was a key catalyst for our plans to launch LTE in 2013 and is therefore good news for our customers.”
