Power line data transmission capacity: Bigger than DSL or cable

Penn State engineers have developed a new model for high-speed broadband transmissions over U.S. overhead electric power lines and estimate that, at full data rate handling capacity, the lines can provide bit rates that far exceed DSL or cable over similar spans. Dr. Mohsen Kavehrad, the W. L. Weiss professor of electrical engineering and director of the Center for Information and Communications Technology Research, led the investigation. He says, "Although broadband power line (BPL) service trials are now underway on a limited basis in some locations in the U.S., these trials run at DSL- comparable rates of 2 or 3 megabits per second.
