We all know what WiFi is. Chances are, you need WiFi on a daily basis – but according to industry experts, the wireless data space will become so crowded that WiFi networks will not be able to handle it. This is where LiFi comes in – LiFi uses LED technology to transfer information at ultra-fast speed. So, could LiFi really replace WiFi in the coming years?
Instead of using radio waves to transport data like WiFi does, LiFi makes use of light waves. LiFi technology uses these light waves as a mechanism to transfer the input commands, which have been switched to binary code. The light waves then decode these messages and carry out the action required.
An initial study on the LiFi concept showed that this form of data transmission could transfer data at a rate of 1 GPBS – that means it is about 100 times faster than WiFi. Some of the uses for LiFi will likely include aviation, solar panels, schools, nuclear power stations, hospitals and in emergency situations all over the world.
Li-Fi tech may be used in cars, planes, solar panels, around schools and lecture theatres, during disasters, on oil rigs and in nuclear power stations, around hospitals, or in homes and workplaces.
LiFi runs with the power of an innovative technology called VLC, or visible light communication. It works by monitoring how many photons LEDs emit, all in a way that humans cannot see or detect in any way. One of the companies that is currently expanding the concept of LiFi powered by visible light communication include Qualcomm, which has technology called Lumicast that may be used in the LED fixtures inside your home, serving the double-duty of charging your devices from a lightbulb – while saving energy.
