Researchers discover method to transmit mobile data a thousand times faster

Mobile speed"Forget 3G and 4G," writes PCMag, University of Pittsburgh researchers have discovered a way to transmit mobile data a thousand times faster. The method uses the terahertz frequency (rather than the currently used gigahertz frequency).

“The ability to modulate light with such a bandwidth could increase the amount of information carried by more than 1,000 times when compared to the volume carried with today’s technologies,” said team leader Hrvoje Petek.

Apparently they're not stopping there, though. Petek says his team is trying to harness "'light-matter interactions' in the petahertz-frequency range, or 1,000 times faster again than the terahertz oscillations they've already achieved," writes PCMag, which has more coverage here.

CNN Money reports "we are running out of wireless bandwidth"

CNN Money's chart using FCC dataCNN Money recently reported that "the supply of wireless data in the United States -- the stuff that lets us use the Internet on our smartphones and tablets -- is fast disappearing," writes Eliot Van Buskirk in Evolver.fm.

He argues that, if true, that may pose problems to media services like Internet radio. Van Buskirk encourages web radio services to offer offline playback options (like Slacker and most on-demand services) as one solution.

He also notes that customers of at least one mobile carrier, AT&T, "are already feeling the squeeze." The carrier is apparently throttling unlimited data users' mobile speeds after they consume less than 2GB of data in a billing period.

Sean Ross ran into that issue earlier this year (RAIN coverage here), though he noted such a issue probably wouldn't impact most mobile web radio listeners.

A new study from wireless bill analysis firm Validas found such behavior on the part of AT&T to be "pointless... throttling does nothing to alleviate network bandwidth issues."
