Slow internet is probably one of the most common things that have the power to annoy us in no time. It has become an indispensable part of our digital lives, and we welcome any improvement in the internet speed with open arms.
Now, the researchers at the Eindhoven University of Technology in the Netherlands achieved a staggering Wi-Fi speed of 42.8 Gbit/s using infrared rays. As the 42.8 Gbit/s is achieved per ray and each device would access its own light ray, the devices won’t have to share bandwidth.
The system being talked about here is simple and cheap to set up. Few central light antennas emit data or the rays of light supplied by an optical fiber. This maintenance free system needs no power to operate.
The direction of rays can be changed by changing the light wavelength, which is controlled using a pair of gratings. If you move from one place to another or the device moves from the antenna’s sight, another light antenna takes over. Also, this system has so far only been used to download data.Since infrared doesn’t pass through walls, one will need an antenna in each room, of course. Compared to other light-based Wi-Fi solutions, this system has an upper hand as infrared light is invisible to human eye.
It should be noted that the process uses a safe infrared wavelength, it’s harmless.
The researchers are currently working to improve this technology. They also hope that soon one will find this technology in stores and homes.
