AT&T unveils AirGig for low-cost wireless broadband along power lines
AT&T on Tuesday announced a low-cost, high-speed wireless internet technology that relies on plastic antennas positioned along medium-voltage power lines.
The signals will not travel through the conductive materials inside the power lines, as with more expensive technologies that were tried and mostly failed a decade ago, AT&T executives said on a conference call.
Instead, the plastic antennas will be attached to the power lines and serve as a mesh network to distribute signals to homes and businesses. To test the technology, AT&T is looking for a location somewhere in the next year with a favorable regulatory environment, since the carrier would need to partner with an existing electric utility.
