A Navy-sponsored researcher has developed a way to add more users to military wireless networks.
Current networks use immense bandwidth by cloaking signals in virtual noise to foil interception. However, Syed Jafar, a professor at the University of California, Irvine, has developed a theory to use bandwidth more efficiently, according to an Office of Naval Research (ONR) news release.
Jafar found that changing the mathematical formulas and algorithms used to design wireless signals allows systems to potentially filter out undesired signals at every network receiver, making other users' interference less intrusive while allowing each user to access half of the total bandwidth free from interference, according to the ONR.
"This means that, in a network of 20 users, each person's available bandwidth can increase by a factor of 10," said Jafar, who recently won the 2015 Blavatnik National Award for Young Scientists. "In theory, everyone gets half the cake instead of one-twentieth. This principle can apply to networks of varying sizes."
Altering the signal design formulas also naturally jams undesired signals, guaranteeing communication security, the Navy said.
