Gigabit Internet without fiber? Could be. AT&T has launched two trials of technology that it says will enable transmission of Internet data via radio waves guided by power lines.

Known as Project AirGig, the technology holds the promise of delivering Internet access at more than 1 gigabit per second.

“[U]sing AirGig patented technology, we would install devices to provide high speed broadband which can be clamped on by trained electrical workers in just a few minutes,” AT&T says. The communications giant has more than 300 patents and patents pending for the technology.

A trial is underway in Georgia and another test has been launched outside the U.S., AT&T announced early Wednesday.

“Project AirGig is part of our ongoing effort to accelerate internet connections to a gig or more through both wired and wireless solutions,” said Andre Fuetsch, president, AT&T Labs and Chief Technology Officer. “But it also stands alone as a radically innovative solution to bridge the global digital divide. If these trials and our continued research and development turn out the way we intend, we’ll take a big step toward bringing hyper-fast connectivity to people everywhere.”

According to AT&T, AirGig could be deployed in many areas not served by high speed broadband today, from rural to urban.

However, AT&T notes that there is no timeline for commercial deployment.
