What is LiFi and why it's preferred over WiFi?

SHARE:

Hello guys here I will be discussing about a real alternative of WiFi ie  LiFi. Yeah in coming few years LiFi is about to take place of WiFi. WiFi which is a great helper for us since one decade is facing a great challenge in form of LiFi. WiFi saves us from data overage and often helps to use good internet in areas of low signal but it suffers a disadvantage of limited spectrum ie  around 2.5Gh to 5Gh. One mere reason for WiFi to loose in front of LiFi is WiFi being insecure yeah you can't imagine your WiFi router to deliver signals only in your room but LiFi can do this for you. We have a trick abut checking of your WiFi is hacked.





What is LiFi?

LiFi is a connectivity technology just like WiFi but LiFi use light for connection instead of radio waves of WiFi. Currently the technology it's using is called SIM OFDM. And how it works is somewhat similar to that of your infrared remote controller used for TV or AC. Yeah it will transform the data in light pulses and will be sent through emitter which later is received by receiver in your device and converted back into data. But the huge difference in speed is because infrared remote uses just a part of invisible part of spectrum but LiFi is gonna use the complete visible part of the spectrum ie  thousands of colours working parallel to transfer data enhancing the speed.
And for the purpose of security it will be encrypted using password. And one of the best as well as worst part is it can't go through opaque objects.

Is LiFi available today?

A bad news is that LiFi is not available today but all it's concepts are ready and being researched on. And we can hope it to be our assistant by coming 2 years.
