KU professor earns patent for wireless technology work

Ron Hui doesn't know if his patented invention for speeding the Internet will ever be needed.

Kansas university professor and researcher Ron Hui has received a patent for newly developed microscopic optical wireless technology. It can be used to generate higher-frequency radio signals that can speed up Internet access.

But if technology continues to demand greater access and speed, Hui has developed a method to do it.

"To be honest, I cannot predict the future," he said.

Hui is a Kansas University associate professor of electrical engineering and computer science. He recently learned he received a U.S. patent for research he did more than five years ago while at Nortel Networks, a Canadian company that does networking and telecommunications services.

Hui's research involved fiber-optic communication and could be used for wireless computer networks. The chips developed by Hui quickly encode information, enabling it to be sent through fiber-optic cables with greater speed.

Hui said there was no need for the additional Web capacity now. Home computer users haven't put much of a strain on the current infrastructure.

"I don't think that's a big driver," he said. "It's got to be something different."

For instance, he said, if high-definition television became popular, it would require additional bandwidth for cable systems.

Since 1983, the transmission capacity of optical fiber systems has doubled every 2.4 years, according to industry data.

Hui worked on the chips for two years and applied for the patent in 1999. He said he hadn't worked on the chips since then, but Nortel Networks will have access to the product if it becomes necessary in the future.

"Right now, we did not follow up on this," he said.

Partner with ITTC

The Information and Telecommunication Technology Center at the University of Kansas has developed several assistance policies that enhance interactions between the Center and local, Kansas, or national companies. 

ITTC assistance includes initial free consulting (normally one to five hours). If additional support is needed, ITTC will offer one of the following approaches: 

Sponsored Research Agreement

Individuals and organizations can enter into agreements with KUCR/ITTC and provide funds for sponsored research to be performed at ITTC with the assistance of faculty, staff and students.

Licensing and Royalty/Equity Agreement

An ITTC goal is the development of investment-grade technologies for transfer to, and marketing by, local, Kansas, and national businesses. To enhance this process, the Center has developed flexible policies that allow for licensing, royalty, and equity arrangements to meet both the needs of ITTC and the company.

Commercialization Development

Companies with a technology need that can be satisfied with ITTC's resources can look to us for assistance. We can develop a relationship with interested partners that will provide for the development of a technology suited for commercialization.

ITTC Resource Access

ITTC resources, including computers and software systems, may be made available to Kansas companies in accordance with the Center's mission and applicable Regents and University policies.
