Wireless networking traditionally assumes that radios are half-duplex. This means on a given frequency, a half-duplex radio can either transmit or receive, but not both at the same time, like a one-lane bridge. Philip Levis, assistant profess or Computer
Science and Engineering at Stanford University, presents recent results demonstrating that a full-duplex radio -- a radio that can receive and transmit simultaneously on the same frequency, like a two-lane bridge -- can be built using commodity, off-the-shelf components. Full duplex has the potential to revolutionize a large number of wireless systems.
