Li-Fi stands for light fidelity and is a new advancement in the world of INTERNET. Almost all the homes these days have broadband connections and everyone has experienced low-speed Wi-Fi. In this time where we don’t even want to wait for our food to arrive after ordering it, how can we expect anyone to wait for the internet connection?
When the internet stops working for 5 seconds, so does our hearts!
So, Li-Fi was introduced recently. It is a VLC (Visible Light Communications) system that supports wireless communications at extremely high speeds. It is also more secure at a much lesser power level.
Li-Fi requires visible light. That means even in daytime people will have to switch on the LED bulbs even during daytime and these bulbs should be installed everywhere in the house because Li-Fi cannot pass through walls.
Li-Fi requires two components; one is the light-emitting source and other is the one that can detect light. Li-Fi has some advantages of security, speed and availability over Wi-Fi but at the same time, it has some disadvantages. Though light is present at almost all places from offices to malls, homes and schools, it is all for urban areas. There are places which are still bereft of power supply. Li-fi is a Visible Light Communication system and since light cannot pass through walls and any physical barrier that stands as another challenge in the acceptance and replacement of Li-Fi over Wi-fi.
There are many issues but for now, we can treat both Li-Fi and Wi-Fi as two separate technologies that can co-exist.
