AT&T has taken its fiber network game plan to the next level with the unveiling of a roadmap that consists of targeting 100 cities and municipalities nationwide.

Aiming to serve both consumers and businesses alike, AT&T touted its U-verse with GigaPower fiber network roll-out would consist of delivering broadband speeds up to 1 Gigabit per second along with U-verse TV.

For the most part, AT&T (as well as a few other telco and ISP competitors -- namely Google) have been dabbling with deploying these ultra-fast Gigabit Internet networks in smaller, tech-heavy metropolitan areas such as Austin, Texas and Provo, Utah .

But AT&T has dreams of striking it rich in the big city, or rather, all of the big cities in the United States.

The nation's second largest wireless provider published a full list of the 21 metropolitan areas where fiber plans are in the works, consisting both of the local metropolis hub as well as surrounding suburbs and towns.

Here's a summary of those candidate areas: 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.

This brings the grand total of metro areas where it is at least exploring deploying U-Verse TV and fiber to 25, following Austin and Dallas as well as the Raleigh-Durham and Winston-Salem markets in North Carolina.

This exploration process includes working with local leaders on financing, developing, and timing the fiber broadband infrastructures and deployment.

Being that the keyword in all of this might be some variation of "exploring," AT&T didn't provide any extra details about timelines or specific dates.

However, AT&T did reiterated its goal to bring its wired IP broadband network to at least 57 million customer locations across 22 states by the end of 2015.
