Data over power lines

Overhead electric power lines have the potential to carry computer data at rates far exceeding those of DSL and cable modems, a Penn State electrical engineer says.

Mohsen Kavehrad, director of the Center for Information and Communciations Technology Research, says his computer models suggest that power lines theoretically could send data to individual homes at rates of hundreds of megabits per second, compared with the typical DSL rate of two or three megabits per second. He presented his findings earlier this month at a networking conference in Las Vegas.
