Nothing can be more annoying than having a poor Wi-Fi connection. As an inevitable part of our daily digital lives, any kind of improvement in the internet speed is warmly welcomed. And luckily, researchers at the Eindhoven University of Technology have come up with a groundbreaking idea to achieve superfast Wi-Fi using Infrared rays.
Super fast Wi-Fi
The capacity of the proposed system is huge; they’ve achieved an incredible Wi-Fi speed of 42.8 Gbit/s using infrared rays. The devices won’t have to share the bandwidth as this staggering speed is earned per ray and each device would get its own ray of light.
Safe & Simple
The system is pretty cheap and simple to install. Few central light antennas radiate infrared light rays supplied by an optical fiber. The whole system requires no maintenance and power to operate. And the best part is the infrared ray is harmless for your eyes.
Better than other light-based Wi-Fi solutions
This system requires an antenna in each room since infrared doesn’t go through walls. However, other light-based Wi-Fi solutions have been limited to slow speeds and relied on LED bulbs. And it’s easy to block regular light with your hand, whereas infrared rays are invisible to human eyes.
No chance of interference
You can change the direction of the ray of light by changing the light wavelengths, which is controlled by a pair of gratings contained by the antennas. There will be no interference if you walk around as a user or move the device from the antenna’s sight; another light antenna will take over. So far, the research team has only used this system to download data.
While some Ph.D. students are working to figure out the way to connect the light antennas with fiber-optics, others are trying to figure out how to track the location of wireless devices. According to project head Tom Koonen, soon we will find this technology in our homes and stores.
