AT&T on Monday published a roadmap that aims to bring fiber Internet connectivity to 100 cities and municipalities across the country. The service would deliver U-Verse TV and broadband speeds of up to 1 gigabit per second to both consumers and businesses, AT&T said in a press release on the matter.

The list of 21 candidate metropolitan areas includes: Atlanta, Augusta, Charlotte, Chicago, Cleveland, Fort Worth, Fort Lauderdale, Greensboro, Houston, Jacksonville, Kansas City, Los Angeles, Miami, Nashville, Oakland, Orlando, San Antonio, San Diego, St. Louis, San Francisco and San Jose.

Factoring in previously announced markets, AT&T now has committed to or is exploring 25 metro areas for fiber deployment.

Lori Lee, senior executive vice president, AT&T Home Solutions, said they're working with communities that appreciate the value of advanced technologies.

It's worth putting a spotlight on the language used by AT&T in the release, specifically, the word "exploring." This means the company is working with local leaders to go over things like development, financing and timing - it doesn't necessarily mean that each of the cities listed in the roadmap are a lock for the service.

AT&T's GigaPower service debuted in Austin and some surrounding communities in December 2013 with plans to roll out in parts of Dallas this summer. The company anticipates its wired IP broadband network will reach 57 million customers across 22 states by the end of 2015.
