A group of scientists from Japan have been tinkering with something that is called the “T-ray” band. It is basically an unregulated part of the network spectrum that lies between 300GHz and 3THz or between microwaves and far infrared waves. When we say unregulated, we mean that for now, no internet service provider uses that network and since it is unused, there is no need for a set of rules or regulations to be implemented for it just yet. The team of scientists has used T-ray to break the record for wireless data transmission in the terahertz range with a data transmission rate said to be 20 times higher than most current Wi-Fi connections.
The team which is based at the Tokyo Institute of Technology has apparently developed hardware that is allegedly capable of transmitting data at a blazing 3 GB/s at frequencies of 542GHz. The results for the experiment were posted in digital letters. To accomplish this, the team made use of a minute 1mm-squared device called a resonant tunneling diode which produced smaller voltage with increasing current. By tweaking the amount of current flowing in, the team hit a level at which the device began to resonate and subsequently it began emitting signals in the terahertz band.
While it is just a design prototype with no practical usability for now, especially since it can only emit signals to a distance of few tens of yards, researchers allegedly think that it might be possible to hit 100GB/s in the future so this doesn’t seem that powerful in comparison. With that said however, you might want to keep an eye out on your data caps if this ever saunters into the consumer market.
