Researchers at Eindhoven University pave the way for 100 times faster Wi-Fi systems

With the growing demands for the speed and efficacy of the existing internet connection across the globe, faster internet technology is the need of the hour. For almost all modern day, heavyweight operations that rely on the web, high-speed internet has become no less than an absolute need.

In the recent breakthrough by researchers at the Eindhoven University of Technology, Netherlands, it has been found out that it is indeed possible to extend the current capabilities and speed of existing Wi-Fi connectivity manifold thus achieving about 100 times the internet speed achievable currently.

The presently deployed technology in the Wi-Fi systems involves the use of radio signals at a frequency range of 2.5-5 GHz with the tendency to get overloaded whenever the traffic over the network increases. In the newly developed system by the team of researchers, the Wi-Fi signals would be using the high frequency and low wavelength alternative of infrared signals. These electromagnetic signals which will be utilised in the system that has been dubbed as the Li-Fi system would be to the tune of 200 THz. With this kind of capability, the system developed at the Eindhoven University would be able to achieve a speed of about 42.8 Gbit/s – a little over 100 times the speed achievable by the best present day Wi-fi systems.

The system would use simple Infrared light through optical fibres that would enable the connectivity to various devices and terminals via light-antennas. The use of light-based broadband technology would also be possible to come up with the precise location of the connected device at any point of time. This particular aspect of it poses several new possibilities regarding the current GPS and other technologies that rely on the exact location of the device. Even though the initial set-up cost of the system could be higher than that of the existing wi-fi systems, the maintenance and other operational costs would be bare minimum as the system does not involve any moving parts nor does it need power for its operation.

This Li-fi system uses the infrared light for the downlink as the downlinks are the ones that use more of the data while it has stuck to the radio signals for the uplink. If the testing and preview of this suggested broadband connectivity system go well, the fully furnished product could be in the markets in the next five years or so.
