Optical Wireless and Broadband Over Power Lines
Penn State engineers have shown that a white-LED system for lighting and high data-rate indoor wireless communications, coupled with broadband over either medium- or low-voltage power line grids (BPL), can offer transmission capacities that exceed DSL or cable and are more secure than RF.
Dr. Mohsen Kavehrad, the W. L. Weiss professor of electrical engineering and director of the Center for Information and Communications Technology Research, and his team have shown that, in the system they designed, coupling white LEDs to BPL can deliver secure, wireless bit rates of a gigabit per second, a rate only exceeded by fiber.
