AT&T expands 4G wireless to Triad, more Charlotte metro area

AT&T (NYSE: T) is expanding its 4G wireless broadband footprint in parts of North Carolina.

As of today, the service was “turned on,” as AT&T said, in Greensboro, Winston-Salem and Burlington.

The 4G service is already available in the Triangle.

AT&T 4G LTE coverage also was expanded outside of Charlotte to include Gastonia; western portions of Lake Norman, along N.C. Hwy. 3 from Kannapolis to Mooresville; along U.S. Hwy. 52 from China Grove to Mooresville; south of Salisbury; and along U.S. Hwy. 601 between Concord and Monroe.

The telecommunications firm formally announced the availability of 4G service in the Durham area in February. 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.
