The high-speed network was rolled out in Atlanta and Athens in 2011, said Ann Elsas, a communications manager with AT&T Strategic Communications. The upgrade was made in Macon, Savannah and Brunswick in the past few weeks, she said.
Elas said 4G is capable of speeds 10 times faster than the 3G network. AT&T should be finished deploying 4G nationwide by year’s end.
Elas said she did not have a specific number of devices in the area that can take advantage of 4G.
AT&T is two years behind its chief competitor in launching a fourth-generation network. Verizon Wireless made 4G available in the Augusta area in July 2011. T-Mobile also offers 4G in Augusta.
Sprint spokeswoman Kristin Wallace said the company has rolled out 4G in Atlanta and other large cities, such as Dallas, Houston and Kansas City, but not in smaller markets such as Augusta. No time frame for upgrading Augusta has been announced.
