Infrared to replace Wifi; transferring data at the speed of light

WiFi is still referred to as a modern technology even after two decades of its introduction but has not progressed much as one cannot sometimes stream HD videos at a consistent rate.

Pakistan now realizes the importance of easy access to the WiFi for everyone as Punjab has taken a step of installing public WiFis in Punjab. The Pakistan Railway has also announced WiFi hotspots in trains while Wateen has introduced first ever WiFi villages of Tharparkar.

These hotspots get connected by thousands of people everyday, but speed remains an issue with many complaining.

The WiFi technology is improving every second but a Ph.D. student from Netherlands has gained attention as he suggests replacing the Wi-Fi altogether. The replacement suggested is infrared light wich makes sense in Physics terms as light obviously travels faster than waves and therefore can transfer data at more speed.

Before this proposition, light has been proposed to replaced WiFi but visible light rather than the infrared one. The transition could not be made because tests revealed slower speeds and an annoying requirement of keeping the lights on at all times.

On the other hand, infrared light has no such requirement and radiates light at different angles enlarging its range significantly although it requires installing antennas in every room.

The task of wiring every room in a house with separate antennas sounds demanding but if a device can promise to multiply your internet speeds, the transition could be worth making.
