New Wireless Tech Lets Radio Devices Send and Receive Simultaneously, Doubling Efficiency
Two-way Wireless Communication Electrical engineering grad students Jung Il Choi and Mayank Jain (along with fellow grad student Kannan Srinivasan, not pictured here) developed the tech along with their professors at Stanford. L.A. Cicero via Stanford Radio communications devices can either send or receive wireless signals at a given moment, but they can't do both at the same time (hence the regular use of the word "over" to signal the end of a transmission). But a team of electrical engineering grad students and professors at Stanford has done what researchers have long thought impossible by developing a new antenna setup that allows wireless signals to be sent and received at the same time. That may not seem earth-shattering--cell phones allow simultaneous two-way communication after all--but given the fact that the breakthrough essentially doubles the speed of communications networks immediately, it's actually somewhat huge. Cell phone networks employ a complicated and expensive...
