Fast, Real Fast Wireless

Dave Bateman Dave Bateman Profile: Dave Bateman

Over the years the speed of wireless networking has increased. I remember when it maxed out at 11 Mbps and it served most everyone just fine. Many wired connections were still running 10 Mbps, so no one really noticed. Then 100 Mbps wired connections starting becoming popular and all of the sudden wireless seemed slow. Over the years it has increased, but never seemed to keep up with the speed a wired connection could offer.

Some folks in Japan are trying to speed up wireless transmission rates to speeds once thought impossible. They are using what they refer to as the “T-ray” band. It is a section of electromagnetic spectrum that falls between 300 GHz and 3 THz. By using this band, they have been able to achieve speeds of 3GB/sec. That’s pretty darn fast. However, you shouldn’t get too excited just yet. You won’t be seeing a “T-ray” router at Walmart anytime soon. Right now it is just a proof of concept and it’s range it pretty short. But I think it is a glimpse of things to come.
