According to The Wall Street Journal, AT&T and T-Mobile have filed a request with the Federal Communications Commission (FCC) asking for approval of a transfer of $1 billion worth of wireless spectrums. This move is a result of the failed $39 billion AT&T acquisition of T-Mobile USA.

AT&T said it would turn over the airwaves, or spectrum, along with $3 billion in cash to T-Mobile parent Deutsche Telekom AG after pulling out of the deal as opposition mounted from the FCC, Justice Department, state attorneys general and rival carriers.

“This additional spectrum will help meet the growing demand for wireless broadband services,” said Tom Sugrue, T-Mobile’s senior vice president for government affairs, in an emailed statement. “We hope the FCC will move swiftly to approve the license assignments.”

T-Mobile has made it clear that it is in need of new wireless spectrums, especially considering that it is the only major U.S. carrier that hasn't rolled out a 4G LTE network. 

AT&T withdrew its acquisition request of T-Mobile on December 19, following nine months of hearings and debates with the U.S. government over the deal.
