NEW ORLEANS (CBS / AP) — T-Mobile USA says Nokia Siemens Networks and Ericsson will supply the equipment for its new wireless broadband network, a project worth $4 billion.

T-Mobile is commissioning a “4G LTE” network, the same technology used by Verizon and AT&T for their high-speed networks. It will use, in part, radio frequencies handed over by AT&T after the bigger company backed off its deal to buy T-Mobile due to opposition from federal regulators.

In addition to handing over spectrum licenses, AT&T gave T-Mobile $3 billion in cash, which will help finance the upgrade. T-Mobile plans to have the network live next year, covering 75 percent of the 25 U.S. largest cities.

T-Mobile USA is making the announcement on the first day of CTIA Wireless, the U.S. cellphone industry trade show, in New Orleans.
