The infrared Wi-Fi
The researchers of this technology noted that it not only has the capacity for 40Gbit/s per beam, but also no need to share since each device has its own beam of light.
Researchers at TU/e in the Netherlands have developed a groundbreaking technology to address the issue of slow Wi-Fi everywhere. Building wireless networks.
This technology offers high capacity with the added benefits of not having to share, since each receiver has a beam of light on their own.
The system explained
The system, for which researcher Joan Oh received her PhD with distinction, is simple and low-cost: The Wireless data comes from a few central “light antennas”, which may be located on the ceiling. These light antennas can precisely guide beams of light from optical fiber. Doesn’t need any moving parts or energy, reliable wireless data as there are no moving parts or power required. Gratings emit light rays at different wavelengths and angles, changing the wavelength changes the data. This low-energy infrared light does not affect the retina and the university statement states that it is completely safe.
If the user moves, the signal from the device isn’t traceable any more. That’s when a second antenna terminals and finds its location. By tracking radio signals, sent at different wavelengths, can identify each new device. Not only does this network not interfere with other wireless networks, but you also won’t be bothered with slow internet.
Today’s Wi-Fi works through signals at 2.5 or 5 gigahertz. The TU/e system taps into light waves with wavelengths at 1,500 nanometers or above: the light frequency here is thousands of times higher (e.g. 200 terahertz), which gives a big boost to efficiency. Joanne Oh achieves speeds of up to 42.8 Gbit/s. By comparision, the average connection speed in the Netherlands is 2,000 times slower at 17.6 Mbit/s. Though they are still relying on radio waves to upload data, the team has only been relying on light to download data. It’s worth noting that other applications may require less capacity for uploading content and this is something the specialists will look into.
