AT&T said it has expanded service for AT&T GigaPower, its fiber-based broadband platform for residential and small business customers to parts of four markets – Atlanta, Chicago, Miami and Dallas/Ft. Worth.

Here’s how the latest batch of GigaPower expansions breaks down:

-Atlanta, including Buford, Jonesboro, Lawrenceville, Norcross, Roswell, Sugar Hill and Suwanee. Standalone 1-Gig service there starts at $70 per month, $120 per month with TV service, and $150 per month for a triple-play.

-Chicago, including Pingree Grove, Plano and Sugar Grove. In that market, standalone 1-Gig starts at $110 per month, while a pay TV bundle starts at $150 per month, and a triple-play bundle starting at $180 per month.

-Miami, including Cooper City, Miami Lakes, Miramar, Pembroke Pines and Plantation. GigaPower pricing there follows AT&T’s pricing for the Chicago area.

-Dallas/Ft. Worth, including Cedar Hill, Colleyville, DeSoto, Joshua, Keene, Keller, Lakeside, Little Elm and Roanoke. GigaPower pricing in Dallas/Ft. Worth mirrors AT&T’ pricing for Chicago.

Customers in those markets have the option to pair GigaPower with DirecTV or U-verse TV services.

Notably, Atlanta, Chicago, and Miami are among the initial handful of markets that Comcast has ticketed for DOCSIS 3.1 to deliver gigabit broadband on its widely deployed HFC network later this year.

AT&T said GigaPower is now available in 20 major metros, and is moving forward on expansions that will extend service to parts of another 36.
