Japanese scientists create super-charged Wi-Fi that's 20x faster

Do you have the need for speed? Wi-Fi speed? Who doesn't? Boy, do we have good news for you! A group of Japanese researchers have just broken the record for wireless data transmission in the terahertz band resulting in data transfers that are 20 times faster than standard Wi-Fi.

According to a new report published in IET Electronic Letters, researchers from Tokyo Institute of Technology have developed a "1mm-square" resonate tunneling diode (RTD) that can tap into the terahertz spectrum to achieve data transfers at 3Gb/s at 542GHz.

The new record bests the previous terahertz data transmission record of 1.5Gb/s at 300GHz set in November by ROHM.

Scientists are also exploring the terahertz spectrum for creating cameras that can see through walls.

But don't get your hopes up just yet. Terahertz Wi-Fi only has a 10 meter range. The terahertz spectrum is also unregulated and costly to create consumer products for, meaning it'll be a ways off before we really see super-charged Wi-Fi hit our homes.

There's a lot of potential for using T-rays. Ultra-fast Wi-Fi is certainly welcome.
