German scientists developed record-setting Wi-Fi at 100 Gigabits per second, 100 times faster than the Google Fiber.

“At a data rate of 100 gigabits per second, it would be possible to send the contents of a blue-ray disk or of five DVDs between two devices by radio within two seconds only.”
For their latest world record, the scientists applied a photonic method to generate the radio signals at the transmitter. After radio transmission, fully integrated electronic circuits were used in the receiver.
In earlier field experiments under the “Millilink” project funded by the BMBF, rates of 40 gigabits per second and transmission distances of more than 1 km were reached.
Professor Ingmar Kallfass he coordinated the “Millilink” project under a shared professorship funded by the Fraunhofer Institute for Applied Solid State Physics (IAF) and the Karlsruhe Institute of Technology (KIT). He said:
“Our project focused on integration of a broadband radio relay link into fiber-optical systems. For rural areas in particular, this technology represents an inexpensive and flexible alternative to optical fiber networks, whose extension can often not be justified from an economic point of view.”
