**ADVANCE FOR MONDAY, SEPT. 3 ** Dr. Joy Laskar explains the new Mulit-gigabit wierless technology his researchers have developed at the Georgia Electronic Design Center at Georgia Tech in Atlanta, Tuesday, July 31, 2007. While Wi-Fi and Bluetooth have emerged as efficient ways to zap smaller files, neither is best suited for quickly transfering high-definition video, large audio libraries and other massive files. Laskar and other scientists at the Georgia Electronic Design Center at the Georgia Institute of Technology have turned to extremely high radio frequencies to transfer huge data files over short spans.
