New record for wireless data transmission set at 6 Gbps

Not only is that better than the current state of the art tech by a full order of magnitude, but it was also achieved over a distance of 37 kilometers (23 miles).

The ACCESS (Advanced E Band Satellite Link Studies) project is a collaborative effort involving a handful of institutions that set the new record using stations in Cologne, Germany, and in the town of Wachtberg, 36.7 km away. The record was set using the so-called "E band" radio frequency at 71-76 GHz that is set aside for terrestrial and satellite broadcasting, which has a frequency range of millimeter waves which allows for huge data rates to be accomplished.

In order to transmit the high bandwidth signal over many miles, the project team upped its power by using efficient transmitters and receivers based around technology called fully monolithically integrated millimeter wave cir­cuits (MMICs). These circuits use transistor technology from Fraunhofer IAF, which has brought us other record-setting super broadband wireless systems in recent years.
