Video footage has been transmitted experimentally (22 meters) using a terahertz wireless signal for the first time, by Terahertz Communications Lab in Braunschweig, Germany.

Using terahertz bandwidth — which ranges from 300GHz to 3 terahertz (THz) — could offer a 1000 fold increase in transmission speed and should open up new frequencies for communication. The as yet untapped terahertz band of the electromagnetic spectrum lies between microwaves and visible light.
