Terahertz video transfer is foretaste of future wireless

Video footage has been transmitted using a terahertz wireless signal for the first time, reports New Scientist.

"Although the link spanned just 22 meters it marks a significant step towards using much faster chunks of wireless spectrum, by harnessing radio waves oscillating a trillion times per second.

The speed at which wireless data can be transferred is limited by the vibration rate of radio waves. Today's fastest wireless technologies, including WiFi and third generation (3G) mobile networks, operate in the ranges of gigahertz (a billion times per second) and megahertz (a million times a second) respectively."
