AT&T (NYSE: T) is now offering its wireless broadband service known as “4G” in Durham.

The telecommunications firm formally announced the availability on Wednesday. 4G service was deployed in Raleigh, Cary and Chapel Hill as of early January.

Verizon Wireless, Sprint and ClearWire also offer their own versions of 4G service in the Triangle.

The expansion in Durham is part of AT&T’s $1.8 billion in network upgrades made across North Carolina over the past four years.

AT&T is utilizing “long term evolution,” or LTE, technology to enable wireless data transmission at broadband speed – fast enough to support video and other multimedia uses.

“Innovation and investment are the keys that will drive economic growth and help create new jobs,” said Cynthia Marshall, President, AT&T North Carolina, in a statement. “We are excited about the new opportunities which this significant capital commitment will open for individuals and communities across North Carolina. Aggressive investing like this is the direct result of decisions made by North Carolina policymakers to create the public policy environment which encourages business and welcomes the commitment of private capital to serve the state.”
