Scientists Set Record for Ultra-Fast WiFi

Japanese scientists have set a whopping record for wireless data speeds—20 times faster than typical WiFi—by using an unconventional part of the electromagnetic spectrum known as the "T-ray" band. The researchers were able to transmit data at 3 gigabytes per second. "T-ray" technology could eventually lighten the load on lower WiFi frequencies that have become jam-packed by data-hungry consumers, reports BBC.

The frequencies on the "T-ray" band range from 300 gigahertz to 3 terahertz, orders of magnitude higher than common WiFi. Theoretically, "T-ray" speeds could peak at 100 gigabytes per second but only at a range of around 30 feet. The scientists at the Tokyo Institute of Technology created a 1-millimeter-square device to hit the ultra-high data rate. (Read more T-ray stories.)
