• Resumen

  • This article reports on using power lines to convey broadband signals. The secret to universal broadband Internet access could be right above your head. Power lines can carry broadband in the form of high-frequency electrical signals, and some European and U.S. utilities are already testing such systems. The problem is that forks in the electrical grid reflect broadband signals and thereby degrade transmission. Pennsylvania State University researchers found that signals should flow fast enough to give homes data-transfer rates of hundreds of megabits per second, tens of times faster than DSL or cable, they told the IEEE Consumer Communications & Networking Conference on January 5.
