Researchers focus on wireless devices

Joe Evans wants your cell phone to get to know your laptop.

Evans is leading a team of Kansas University researchers investigating how wireless devices communicate with one another.

The research is guided by the Bluetooth Special Interest Group, an Overland Park-based consortium of businesses developing a standard chip that someday could be included in most wireless devices.

The goal is to be able to transmit data from one source to another, and to make it as easy as possible.

"Five minutes after you have a gadget out of the box, you should be able to get it to work with another Bluetooth device," Evans said. "You don't have to be a computer scientist to do it."

Researchers are looking at how about 20 devices interact with one another. Evans said much of the interaction is based on the software built into devices, not the chip itself. That means almost every device will need to be tested with other devices to see whether they work together.

That leads Evans to expect further research possibilities in the future.

"The number of combinations and permutations is frightening," he said.

Some of the possible applications for the technology include:

Hands-free, wireless headsets for cell phones.

Transmitting calendar information from a personal data assistant (PDA) to a laptop computer.

Transmitting electronic business cards from device to device.

Using a cell phone to open a garage door.

Evans said his research was centered on making the electronic interactions simple to use.

"If you want to send somebody an electronic business card, it's not very useful if you have to spend 20 minutes figuring out how to do it," Evans said.

Evans said only a handful of devices on the market offered Bluetooth chips. More were available in Europe.

But he expected Bluetooth communication to be a common technology in the next few years.

"We're just seeing the wave of this technology," he said. "I expect to see more and more of this. I think there's a lot of benefit to the manufacturer and to society as a whole."

Bluetooth, formed in the mid-1990s, includes many major technology companies, including 3Com, Agere, Ericsson, IBM, Intel, Microsoft, Nokia and Toshiba. Its chairman and executive director is Mike McCamon, a 1985 KU graduate who also has worked for Intel.

Evans, a professor of electrical engineering and computer science, said McCamon came to KU last year looking for researchers for the project.

The initial project, funded by about $34,000 from Bluetooth, started in December and will be complete by the end of spring.

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.
