How would you like 100 Gb/s over wireless?



In an experiment funded by Germany's BMBF, researchers have transmitted 100 Gb of data per second (the equivalent of 2.5 DVDs) over the grand distance of 20 meters. Before you are underwhelmed, sister project transmitted 40 Gb/s to another station over 1 kilometer away in a field experiment earlier this year. The researchers are designing these experimental wireless systems to integrate seamlessly with existing fiber optic networks.



How are they getting these amazing speeds?



The earlier field test at 40 Gb/s used higher frequencies (200-280 GHz) and experimental transmitter and receivers. The higher frequencies allow the increased speed and large volume of data. The experimental transmitter/receivers enabled them to use the higher frequencies.


To get the 100 Gb/s speeds, researchers used a photonic method - a photon mixer generates the radio signals for the transmitter - to produce the high frequency radio waves. By applying photonic methods, data from a fiber-optic system can be directly converted to a wireless signal. Of course, they must use the experimental transmitter/receivers to use the signal.

Take a look at their sadly paywall-ed article in Nature Photonics for more information.



This is amazing, and I hope someone makes this into a wireless standard pretty fast. I would definitely volunteer to be part of that beta.
