UCR explores LEDs for communication

July 13, 2009 12:00:00 AM PDT
University of California, Riverside, is leading a multi-campus effort that could reshape the way we communicate and navigate in homes, offices, airports and hospitals.The University has received a $3.5 million grant for its Center for Ubiquitous Communication by Light. The center is investigating the use of LEDs to connect the world.

"PDAs, HDTV, information kiosks, computers and laptops, all can be interconnected wirelessly through visible light," said Zhengyuan Xu, professor of electrical engineering and the principal investigator of the new research center.

Xu will work with research experts in communication, navigation, transportation, networking and circuit integration to take advantage of the communication properties of LED lights.

The project is set to begin in January 2010 and run for five years.

Xu says the project on LEDs could have a tremendous potential impact.

"With a proper data interface to a wired data network such as Ethernet, they make it possible to build very low cost communication and navigation systems on existing lighting infrastructure," said Xu.
