Li-fi like WiFi is a Internet network which works through Led lights. The main procedure is to transfer data through the on/off of a light bulb. This procedure will not disturb the humans because the switching will be too fast to notice. The data is first transferred to binaries and then the led bulb will transfer the data with the help of light. The main flow is same as the WiFi network because the WiFi uses radio rays to transfer data and LiFi uses lights to transfer data. Though LiFi is much faster than WiFi.
Pros of LiFi:
1. LiFi is faster than WiFi by 100 times( Yes 100 times)
2. LiFi is more secure than WiFi making it harder to be hacked by Hackers.
3. LiFi is easier to be set up and it will be cheaper in future. The main device is just a Led bulb with a chip at its base.
Cons of LiFi:
1. Though LiFi is faster than WiFi it’s range is short
2. The LiFi system is not currently as much consistent as WiFi.
3. The LiFi network speed decreases when the light is reflected from a unsmooth wall. Though it’s speed will be better than WiFi
Where can it be used?
The LiFi network can be used in closed networks like aeroplanes, offices, Nuclear power plants, Defense systems etc. In homes LiFi can be connected to WiFi to use LiFi as a hi speed router. The WiFi can transmit over long distance but LiFi over short distance. This makes a wonderful combination.
Overall, the total process is same as WiFi. I hope, one day we will see every home with a LiFi and the total speed of data transmission will increase. This system is very much necessary because a statistics says that the total data transmission in 2019 will become 10 times more than present.
