ECE Professor Christopher Davis was issued U.S. Patent No. 7,106,971 on September 12 for his invention, "System and Method for Optical Wireless Communication." His system facilitates optical wireless communication with fading resistance. A delayed diversity approach reduces fading significantly by sending data in a set of light signals which each have a different polarization and/or a different wavelength. Each light signal is carried over a different, uncorrelated "channel" through the atmosphere. The receiver adjusts and combines the signals into a single signal.

For more information on the invention, visit the U.S. Patent Office website.
