A team of researchers has developed a technology that has the potential to double the speed of wireless radios â€“ such as those used by Wi-Fi â€“ by allowing signals to be received and transmitted simultaneously.
"Textbooks say you can't do it," said Stanford University assistant professor Philip Levis when announcing the breakthrough. "The new system completely reworks our assumptions about how wireless networks can be designed."
"Designing radios that can receive and transmit at the same time was thought to be generally impossible," says fellow assistant professor and team member Sachin Katti in a video accompanying the announcement.
