Researchers at the University of Pittsburgh may have hit upon a way to get more data traffic over spectrum, although the solution is still likely a few years away from being realized. The researchers have discovered ways to take advantage of Terahertz bandwidth--the portion of the electromagnetic spectrum between infrared and microwave light. The way they have accomplished this is by producing a "frequency comb," or dividing a single color of light into a series of evenly spaced spectral lines for a variety of uses, that spans a more than 100 Terahertz bandwidth. According to a Pitt professor, doing so could increase the amount of information carried by more than 1,000 times when compared to the volume of data carried with today's technologies. However, as GigaOM recently noted in discussing similar research from the University of Texas at Dallas and the Semiconductor Research Corporation, radios that take advantage of such techniques are likely years away from being commercialized, and it's not entirely clear that the technique will be used specifically for mobile broadband.
