German scientists break WiFi speed record

Researchers in Germany have smash the world record for the fastest wireless internet speed that could have potential in bringing superfast wireless broadband to rural areas. 

A team of researchers from Fraunhofer Institute for Applied Solid State Physics (IAF) and the Karlsruhe Institute of Technology (KIT) have managed to create a wireless network capable of transmitting data at 100Gbps using the ultra-high frequency 237.5 GHz spectrum. 

The team has already set a world record for a 40Gbps wireless network only a few months ago. 

She may not look like much, but she’s got it where it counts.

Read Recombu Digital’s guide to WiFiWhile the technology can transmit vast amounts of data, it cannot penetrate walls that well. However, it could be used for line-of-sight applications such as transmitting data in rural areas. 

“For rural areas in particular, this technology represents an inexpensive and flexible alternative to optical fibre networks, whose extension can often not be justified from an economic point of view,” said Prof. Ingmar Kallfass of the Fraunhofer Institute for Applied Solid-State Physics. 

“At a data rate of 100 gigabits per second, it would be possible to transmit the contents of a blue-ray disk or of five DVDs between two devices by radio within two seconds only.” 

But the team is working on increasing speeds to such an extent that it may make its present efforts look like dial-up in comparison. 

“By employing optical and electrical multiplexing techniques, i.e., by simultaneously transmitting multiple data streams, and by using multiple transmitting and receiving antennas, the data rate could be multiplied,” says Swen König from the KIT Institute of Photonics and Quantum Electronics (IPQ), who conceived and conducted the recent world-record experiment. “Hence, radio systems having a data rate of one terabit per second appear to be feasible.” 

As reported by Recombu, BT demonstrated what it’s claimed to be the world’s fastest commercial broadband service, running at an eye-melting top speed of 10Gbps in November last year. 

In May, Samsung announced that its successfully tested 1Gbps speeds using new 5G technology and expects services will be on the market by 2020.
