IR-based Wi-Fi has a speed of 42Gbps:researchers
Even if you have Fastest wifi,you won't get more than 300Mbit per second speed in total.
However, researchers now claim to have achieved Wi-Fi at a lightning speed of 42.8Gbit per second which is 100 times faster.
The team from Eindhoven University of Technology, Netherlands came up with a surprising solution to beat slow Wi-Fi: a wireless network based on harmless infrared rays.
The capacity is not only huge (more than 40Gbit/s per ray) but also
there is no need to share since every device gets its own ray of light,
said lead researcher Joanne Oh.
He managed a speed of 42.8Gbit/s over a distance of 2.5 metres.
The system conceived in Eindhoven is simple and, in principle, cheap to set up.
The wireless data comes from a few central 'light antennas', for instance mounted on the ceiling, which are able to precisely direct the rays of light supplied by an optical fibre.
Since there are no moving parts, it is maintenance-free and needs no power.
The antennas contain a pair of gratings that radiate light rays of different wavelengths at different angles.
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.
Moreover, there is no longer any interference from a neighbouring Wi-Fi network, the researchers noted.
