University of California, Irvine professor Syed Jafar recently won the 2015 Blavatnik National Award for Young Scientists for his work on network information theory. Jafar's work, which could help military wireless networks become larger, faster, and able to accommodate more users, was sponsored by the U.S. Office of Naval Research (ONR).
"Dr. Jafar has conducted game-changing research in the study of wireless network capacity," says ONR program officer Satanu Das. "This has helped us explore new frontiers in bandwidth efficiency for military communication networks."
Jafar's research determines how much user capacity a wireless network can hold. Existing wireless networks have a limited amount of bandwidth and user capacity, so when more users connect to a specific wireless network, the connection slows down. Jafar's research shows that by changing the mathematical formulas and algorithms used to design wireless signals, it is possible to potentially filter out undesired signals at every network receiver, making other users' interference less intrusive while enabling each user to access half of the total bandwidth free from interference. "This means that, in a network of 20 users, each person's available bandwidth can increase by a factor of 10," Jafar says.
