Wireless networks — computer systems that use radio waves instead of cables to connect different mobile devices in various locations — are now an integral part of modern life. Wi-Fi networks can be found everywhere, in homes, offices, schools, libraries, coffee shops, hotels, hospitals and airports to name a few.

To meet the dramatic growth in network traffic, researchers are looking for ways to increase the “spectrum efficiency” of wireless networks.

“Spectrum efficiency refers to the information rate that can be transmitted over a given bandwidth in a specific communication system,” explains Prof. Jie Wang, chair of the Computer Science Department. “It is a measure of how efficiently a limited frequency spectrum is used.” 

Wang is collaborating with researchers from the University of Texas, Arlington, and George Washington University to develop innovative waveform designs to improve spectrum efficiency. The project is funded with a three-year $140,000 grant from the National Science Foundation (NSF).
