What is LiFi Technology
LiFi is a network technology that uses visible light communication (VLC) to send data at high speeds with low latency. It transmits information through LED lights, not radio waves like WiFi does.
LiFi networks operate in the unlicensed spectrum which means they can share bandwidth with other devices without having to worry about interference or interruptions.
This translates into higher speeds and lower latency for consumers who use the technology on their computers, tablets, and smartphones.
LiFi has the potential to completely replace our internet systems that currently use WiFi and it is safer than Wi-Fi because the signal cannot travel through walls and doesn’t interfere with household appliances like microwaves.
There are already many companies working on LiFi hardware solutions including major names like Intel, Nokia, and Harman International.
The Problem with WiFi
The current form of WiFi internet connection sends data via a radio wave. This creates two issues:
it takes up large amounts of bandwidth (which causes regular slowdown) and, because the signal travels in the air, it needs to go through a receiver before reaching the computer.
The receiver collects the information and then transmits it back to the source through wires. However, using this form of connectivity limits distance between devices to 200 ft which can cause problems with other equipment interfering with signal strength.
Lifi solves both of these problems by replacing radio waves with pulses of light which are sent straight from one device to another.

Other Problems with WiFi
WiFi has come a long way, but it still has many limitations. It’s severely limited by the speed of light and while an antenna can shoot out radio waves, those radio waves are focused in one direction.
This limits how far the signal can go and creates interference from other sources of electromagnetic radiation in the environment (microwaves, cellular phones, etc.).
WiFi has very high capacity for data transfer in some directions (from your computer to a router), but not as much in others (from a router to your computer).
If you’re on a slow connection this can be pretty frustrating because any time you do something with content like watching a video or downloading files, you need to wait for that request to go through before anything else happens.
With wireless internet, the more devices connected to the network at once, the slower everything will get for everyone.
So if you have a wireless internet plan with five people on it at home then all of them will be fighting over bandwidth which slows down their experience significantly.
Light travels faster than sound; so we would hear a plane first and see it second.
That same principle applies to WiFi signals–we see them before we get online with them, and even though they travel really fast they can’t keep up when there are too many users around at once.

The Solution with LIFI
The modern world of wireless communications has improved our lives, to say the least. It’s allowed us to communicate and share information with anyone in the world, anytime we want.
However, it also introduces its own set of challenges – slow speeds and too many devices! To make matters worse, 5G or mmWave (millimeter wave) signals are not yet feasible for indoor use because they don’t reach far enough.
So if you live in a large house or even an apartment that’s on the fifth floor, chances are your wifi doesn’t work well at all.
That’s where LiFi comes in! Unlike WiFi, LiFi transmits data via light rather than radio waves, which can transmit data much faster than WiFi. And unlike 5G, light can penetrate through walls and windows without any issues!
And if that wasn’t cool enough already, one other major advantage of LiFi is its lack of interference from other electronic devices.
Since Wi-Fi operates within the same frequency range as Bluetooth and other common household appliances, there are often interferences which reduce the performance of each individual device by up to 10%.
With LIFI technology, this isn’t a problem at all since there’s no interference from anything else in the environment
Features of LIFI Network
1. The speed of internet transmission up to 200 Gbps
2. LIFI can be more efficient because it uses a different light wavelength
3. Uses standard visible light, avoiding dangerous infrared radiation or Wi-Fi’s microwave range, which has been shown to affect cellular activity, says Tech Republic
4. There are no users or devices connecting to a router as in WiFi access points that all share the same wireless signals; instead, each device has its own receiver (transmitter and receiver)
5. Signals reach about 10 metres and don’t need line of sight like radio waves do
How Lifi Can Change The Future
Widespread adoption of LiFi is a ways off, though there is plenty of promise in LiFi, but at this point, not enough data is available to adequately evaluate the technology.
One of its biggest selling points for improving security is its core limitations; these will have to be addressed before it is used at the grand scale that WiFi is.
LightFidelity (LiFi) would be a benefit to high-density housing, where WiFi routers are currently fighting to provide bandwidth on an increasingly saturated WiFi spectrum for residents, while also wanting to provide a reliable connection.
Because it transfers data through 1,000 times more of the unlicensed, unpaid light spectrum, LiFi becomes a complement to all current, soon-to-be-invented, and future technologies and inventions.
In other words, LiFi is using light (Light Fidelity) to transfer data, reaching every light-illuminated device.
A LiFi system uses Visible Light Communication (VLC) to transfer data, working by converting data into light beams from LEDs, communicating as you turn on and off LEDs at an impossibly fast rate.
LiFi technology uses transceiver-equipped LED bulbs, which can light up a room while also carrying out information transmission and receiving.
Wherever an LED light is, the potential exists for using LiFi to access mobile Internet at an incredible rate of speed, safely and securely.
Since planes already use LED lights inside the cockpit, LiFi can address this issue, and provide an improved method for passengers to get and send data using mobile devices.
LiFi uses any available LED light sources, like bulbs, to send data, meaning that your company is most likely already equipped to handle LiFi data.
When using LiFi in a closed space, you can be sure your connection is safe. As the lights are blocked off by a wall, the data transmitted via LiFi technology will be more private and secure.
As light cannot intrude into a physical environment, LiFi allows for secure data transmission while keeping the privacy intact.
If you are running a company dealing with confidential data, or simply looking to improve online security, you may use LiFi for your vulnerable devices.
Right now, LiFi cannot completely replace WiFi as your connection source, however, there are a few LiFi companies working on developing LiFi products and promoting LiFi as a leading wireless technology.
In an arena filled with different wireless communications technologies, light-fidelity (LiFi) has emerged as promising innovation that has the potential to disrupt the communications industry.
Currently, LightFidelity technologies are focused on using the light of light-emitting diodes (LEDs) for data communications.
LiFi uses the light waves of LED bulbs–which are quickly replacing incandescent bulbs because of their energy savings and longevity–to communicate data, thus LiFi provides lighting and wireless data communications simultaneously, with the same devices.
LiFi technology is the future of internet networking for us. LiFi is short for Light Fidelity, and is a system of communicating through visible light used to transmit wireless data embedded within its beams.
