Li -FI : Next big revolution in the Internet World
Imagine a world where every LED light is an access point of the Internet, a world where 100 GB data transfer within seconds will be just normal. That’s gonna be the world of Li-Fi.
Internet has become such a crucial part of our life that we cannot imagine living a single day without it. And with more and more devices getting connected due to internet of Things, the consumption is just going to increase exponentially.
Currently, more than 60% of the Internet consumption requirement of the world is met by Wi – FI. And if Wi- Fi is helping us with all our needs, then why look for alternative sources.
Why Li – Fi ?
Even-though Wi-Fi is widely used sources of Internet, it still raises some vulnerability and concern :
- Availability of Limited Spectrum : With billions of devices getting connected to the internet and the number increasing exponentially, the spectrum is getting filled up.
- Licensing Spectrum throughout the world is quite a challenging task.
- Limited Bandwidth : It’s not possible to transfer heavy data, especially if the data is in multiple GBs
- Security concern : Wi- Fi transmission takes place using radio signals which can travel through walls and could raise security issues.
Imagine a hacker sitting outside your house trying to enter into your system, they can easily do so with the help of Wi-Fi and this is the main reason it is not a preferable option for high security places like Defense.
Li- Fi on the other hand, resolves all the above issues and provides us much much more.
What is Li-Fi ?
Li-Fi or Light Fidelity is a technology which enables wireless communication with the help of light.
Any data which we are willing to transmit is converted into 1’s and 0’s in front of the light source which acts as a transmitter and at the receiver end, these bits are converted into complete data with the help of a photodetector.
What Li-FI has to offer ?
- Since, data transfer in Li-Fi happens with the help of light, it offers unprecedented speed. This is at least 10x faster then Wi-Fi.
