The Federal Communications Commission cleared T-Mobile US Inc. to acquire much of the wireless business of US Cellular Corp and some of its network infrastructure.

UScellular would struggle to "compete vigorously in the relevant market" if an injunction prevented T-Mobile from acquiring UScellular's wireless operations, Assistant Attorney General Gail Slater of the U.

The Department of Justice dropped its antitrust investigation into T-Mobile US’ pending purchase of smaller telecommunications rival UScellular, but warned the deal could mark an anticompetitive turning point for the domestic wireless telecommunications industry.
