AT&T has charged up the paddles, yelled “clear!”, and fired the defibrillator into one of telecommunications’ worst ideas: broadband over power lines (BPL).
Except, as chief strategy officer John Donovan stressed in a media call, this isn’t BPL, it’s kind of wireless-broadband-near-powerlines.
The Reg wasn’t invited to the call, and AT&T’s statements and video (below) are annoyingly vague about the technology.
However, Donovan said the company’s gone public because the patents it’s been filing for “AirGig” were starting to attract attention, so we went to the USPTO.
