LONDON, U.K. - A new wireless internet system developed by scientists is said to be 100 times faster than the existing wi-fi network.
Scientists have revealed that the new internet is based on harmless infrared rays and has the capacity to support more devices without getting congested.
Researchers said in a statement that wireless devices in the home consume ever more data, and it is only growing, and congesting the wi-fi network.
The wireless network has been developed by researchers at Eindhoven University of Technology in The Netherlands and has a huge capacity - boasting of more than 40 Gigabits per second (Gbit/s).
They revealed that in the new network developed, there is no need to share since every device gets its own ray of light.
It is also cheap to set up, they said, adding that the wireless data comes from a few central 'light antennas', for instance mounted on the ceiling, making it capable of precisely directing the rays of light supplied by an optical fibre.
Further explaining, they revealed that the antennas contain a pair of gratings that radiate light rays of different wavelengths at different angles.
“Changing the light wavelengths also changes the direction of the ray of light. Since a safe infrared wavelength is used that does not reach the vulnerable retina in your eye, this technique is harmless. 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 takes over,” researchers explained.
Adding that the network tracks the precise location of every wireless device using its radio signal transmitted in the return direction.
Devices meanwhile are assigned different wavelengths by the same light antenna and so do not have to share capacity.
“The new system uses infrared light with wavelengths of 1,500 nanometres and higher. This light has frequencies that are thousands of times higher, some 200 terahertz, which makes the data capacity of the light rays much larger,” they added.
Researchers said that they had managed to achieve a speed of 42.8 Gbit/s over a distance of 2.5 metres.
The very best wi-fi system cannot get more than 300 Megabit/s in total.
