Internet speed is set to increase hundred fold as researchers in Netherlands have developed a new WiFi system based on infrared rays.
With the increased use of internet by a growing population, the WiFi network is bound to be congested and slow WiFi is a cause of irritation for many.
Researchers at Eindhoven University of Technology in The Netherlands have developed a wireless network which has a huge capacity - more than 40 Gigabits per second (Gbit/s). Every device gets its own ray of light which eliminates the need for sharing.
In this system, 'light antennas' are mounted on the ceiling. The wireless data comes from these central light antennas which very precisely direct the rays of light supplied by an optical fibre.
The antennas can radiate light rays of different wavelengths at different angles. A change in the wavelength triggers a change in the direction of light. Researchers say that this technique is harmless as the infrared wavelength that is used does not reach the vulnerable retina in the eye.
One interesting aspect of this system is that the network is able to track the precise location of every wireless device using its radio signal transmitted in the return direction. Besides that, adding devices is very simple as they are assigned different wavelengths by the same light antenna. This also strikes out the possibility of any interference from a neighbouring WiFi network.
