Researchers develop new wireless technology for faster, more efficient networks

"Wireless communication is a one-way street. Over." Radio traffic can flow in only one direction at a time on a specific frequency, hence the frequent use of "over" by pilots and air traffic controllers, walkie-talkie users and emergency personnel as they take turns speaking. But now, Stanford researchers have developed the first wireless radios that can send and receive signals at the same time.
