Findings could lead to 1,000-times faster 4G

A research team at the University of Pittsburgh has come up with a way to increase wireless data transmission speeds by a factor of thousands. Headed up by Hrvoje Petek, a physics and chemistry professor at the University's Dietrich School of Arts and Sciences, the team has reportedly created a "frequency comb" that includes over 100THz (terahertz) of bandwidth. It does so by "exciting a coherent collective of atomic motions in a semiconductor silicon crystal."
