"Two-way" radio breakthrough doubles Wi-Fi performance2011-02-16 09:45 by DanielaTags: Wi-Fi
Wi-Fi and mobile phone radio network speeds could double after scientists showed radio is able to send and receive over the same frequency at the same time. The technology would overcome the problem best exemplified by pilots having to say "over" each time they take turns in talking over radio, but it could also be applied to wireless data networks, scientists at Stanford University said. "Textbooks say you can't do it," said Philip Levis, assistant professor of computer science and electrical engineering at Stanford. "The new system completely reworks our assumptions about how wireless networks can be designed. Unlike radio before it has the unique ability that it can receive and transmit at the same time." The technique mimics the way humans are able to screen out the sound of our own voices during a conversation. "It's like two people shouting messages to each other at the same time," said Levis. "If both people are shouting at the same time, neither of them will hear the other." Read more -here-
