Infrared light can increase internet speed a thousand times
A professor at the Technical University of Eindhoven presented a new method of transmitting data using infrared light, which is much more efficient than conventional Wi-Fi or even 5G.
The new data transmission system uses infrared antennas that send invisible beams to connected devices. The speed of such a connection can reach 112 Gb / s. In this case, the channel is not divided between all devices, each gadget will receive such a speed. Whereas Wi-Fi is forced to allocate bandwidth and operate at lower speeds.
Principle of operation
The “infrared” internet model consists of a light source and a small optical receiver on the device itself. The IR light source is a bundle of optical fibers and a lens that directs the signal directly to the device. The smartphone or tablet must have a receiver consisting of a wide-angle lens and photodiodes to convert the optical signal into digital.
So far, researchers have not learned how to send data back by infrared light, so Wi-Fi is used for this. But devices typically transfer much less data than they consume, so this shouldn't be a big problem, Spectrum reports.
Wi-Fi is also used to position the device in space so that the IR light source can accurately direct the signal. If the user leaves the room, the system automatically switches to another source. But while the author of the discovery, Professor Tom Kuhnen, does not talk about plans to release the technology to the masses.
