Infrared Rays-Based Internet Is Now 100 Times Faster Than The Existing Wi-Fi System
Wireless networks crafted from the rays of infrared light could soon allow you to connect to the internet 100 times faster than current Wi-Fi systems. Researchers have found a new method that relies on the central ‘light antennas‘ to beam rays of different wavelengths to wireless devices that mean networks won’t get jammed by several competing devices.
A light-based system, which is also known as ‘Li-Fi,’ could make the wireless networks much more secure, and researchers now say that it could hit the stores within five years. Scientists developed a new wireless internet, based on harmless infrared rays that are 100 times faster than existing Wi-Fi network and can support more devices without getting congested. Slow Wi-Fi is the source of irritation that nearly each and everyone experiences.
The wireless network developed by researchers at the Eindhoven University of Technology in The Netherlands not only has a huge capacity of more than 40 Gbit/s (Gigabits per second) but also there is no need to share since every device gets its ray of light.
The system is a straightforward and cheap way to set up. The wireless data will come from a few central ‘light antennas’, for instance like mounted on the ceiling, which can very precisely direct the rays of light provided by an optical fibre. The antennas will contain a pair of gratings that will radiate the light rays of different wavelengths at different angles like ‘passive diffraction gratings.’

Changing the light wavelengths will also modify the direction of the ray of light. Since a safe infrared wavelength nearby and that does not reach the vulnerable retina in your eye, this technique is harmless. The researchers said that if you walk around as a user and your smartphone or tablet moves out of the light antenna’s line of sight, then another light antenna will take over. As the internet in every human life is a basic necessity, working with much faster and safer internet is likely to attain sooner.
They also said that the network would track the precise location of every wireless device using its radio signal transmitted in the return direction. It is a simple matter to add devices as the same light antenna assigns them different wavelengths and so they do not ought to share capacity. Besides, there is no longer any interference from the nearby Wi-Fi network.
