AT&T said it will offer far faster “gigabit” home Internet speeds in limited parts of metro Atlanta starting Monday.

Residential and small business customers in certain parts of the cities of Atlanta, Decatur, Sandy Springs and Newnan will be eligible to sign up for the service, the company said at a press conference Monday morning.

The AT&T price — $120 a month per month for Internet only service — is significantly higher than the $70 or so range that rival Google has indicated it will offer for similar service in some parts of metro Atlanta. The gigabit-per-second speeds are 100 times faster than what the average U.S. home has.

Comcast, the metro area’s dominant cable TV provider, recently announced local plans for 2 gigabit-per-second speeds — twice as fast as that pledged by either Google or AT&T locally. Comcast is expected to roll out its service next month.
