A word that seems strangely familiar, LiFi, is a form of technology that may see widespread use soon. You may confuse it with WiFi, but no, they are not the same, in fact, LiFi is the big brother in the family. In this article, you will find out just what is LiFi, as well as its features and applications.
What is LiFi?
LiFi is a tech, it’s wireless, and it allows for the transfer of data. It’s just like your WiFi, only around 100 times faster. This is made possible by the principle of visible light communication.
Professor Harald Hass has invented a form of LiFi named Light Fidelity. The system uses led to data transmission and reception. It functions in an optical band between 380 nm and 780 nm. It is getting its acronym, VLC because this is the realm of visible light.
This tech has three types of operational platforms: namely, infrastructure, vehicle, and mobile. A non-mobile station using LiFi would receive a heightened security level as light cannot penetrate walls. That is if the 224 gigabits per second does not sell the tech enough.
- Efficiency. The tech employs visible light as a medium due to it being abundant is homes and workplaces. Users could use their light sources as a means to provide connectivity as well. Providing more cost efficiency and speed.
- Availability. Because LED light sources are pretty much everywhere, that is all you need to connect to the internet, rather than looking out for a WiFi sticker on a restaurant.
- Security. Among the most significant selling points, the security LiFi brings could be invaluable as light is pretty tricky to hack into, especially from outside a building, where it cannot be seen or accessed.
- Darkness. Some places need an absence of light to function correctly, and others don’t have light. So one could find quite a few locations within a city and outside of it where LiFi won’t be available.
- Walls. While a useful security feature, this limits signal range as well as interactive applications within specific structures.
- Interference. LiFi gets you connectivity over individual light sources. That is just fine, but it is also a significant problem. As only specific light sources will provide signals, others will interfere with the signal, causing distortions.
