Li-Fi stands for Light Fidelity Technology, and it is one such wireless technology. Li-Fi uses both infrared and visible light spectrum to provide high-speed data communication. For example, Wi-Fi uses radio signals to send information, but lifi technology speed uses a network of Light Emitting Diodes (LED light bulbs) to transmit data. lifi technology speed.
What is lifi technology speed?
Although the name of Li-Fi may sound a bit strange to you, but you use lifi technology speed when you click on your television remote. The term Li-Fi was first used in 2011 by Professor Harald Haas, University of Edinburgh. He asked what would happen if all the light bulbs in the world could also transmit data? He also explained there that how more data can be communicated in a secure way than a cellular tower with the light of a single LED. Harald Haas also formed a company named PureLifi to develop Li-Fi technology. Their purpose was to create a plug-and-play system that would work with USB devices.
What does 5G have to do with this?
If you do not know, then tell that the main focus of 5G Internet is on speed. Everyone believes that 5G will be very fast in every respect. You will not see much difference in speed while using Facebook or Reddit in your phone. Yes, but in the case of Processing Power, you will get a different experience. When you download a movie or music file, you will see a huge difference compared to 4G.
5G is the name given to the latest version of cellular mobile connections that will provide better performance speeds than 4G (LTE/WiMax), 3G (UMTS) and 2G (GSM) systems. Local Antenna connects to telephone network and internet with very high bandwidth.
5G is 100 times faster than 4G. This improvement in performance is due to higher invisible radio waves. And 4G, 3G, and 2G networks use lower frequencies. Unlike 5G and previous networks, Li-Fi uses radio waves in the visible spectrum, which are faster and have higher bandwidth.
What is 5G Technology and How It Works Benefit of 5G
How Powerful Is lifi technology speed?
Li-Fi transmits data at a speed of 1GB per second, which is 100 times faster than Wi-Fi. Using the infrared and visible light spectrum, Li-Fi is at least 2600 times larger in size than a 300 GHz radio frequency spectrum.
In contrast, a limited number of radio frequency bands are available in Wi-Fi. This is necessary because businesses purchase wireless gadgets, relying only on the Internet of Things (IOT).
The Internet of Things which is also known as IoT, means how all the devices are connected with each other. If you have Smart Light or Smart Fridge in your home then you are using IOT.
The number of bands is in limited quantity, so due to the increase in demand in today’s time, it has become very difficult to move the data. Some sources say that by 2020 there will be 50 billion devices which will always be connected with the whole world. 5G requires a lot of radio spectrum. So by sending this 5G Demands to Li-Fi, the radio spectrum is reduced a bit, so that the increasing Internet traffic of the world can be handled.

lifi technology speed always needs a light source
Light must always be on for Li-Fi to work. Li-Fi needs a clear line, just like your TV remote. Your device will always need a clear path with a Li-Fi transmitter, so it will be a bit difficult to get a connection if you go out with your mobile.
What is the difference between LiFi and WiFi?
Both LiFi and WiFi send and receive data without wire. Routers and Radio Frequency are used to transfer and receive data in WiFi and LED bulbs and light signals are used to transfer and receive data in LiFi.
Below we will tell what is the difference between LiFi and WiFi.
1. Definition
WiFi has Full Form- Wireless Fidelity and LiFi has Full Form- Light Fidelity.
2. Invention
WiFi was invented by NCR corporation in 1991 and LiFi was invented by Prof. Posted by Harald Haas in 2011.
3. Operation
Routers and Radio Frequency are used to transfer and receive data in WiFi and LED bulbs and light signals are used to transfer and receive data in LiFi.
4. Device Compliance
WiFi works in any WLAN 802.11/b/g/n/ac/d standard device and LiFi works in all IrDA devices.
5. Data Transfer Speed
Data Transfer Speed of WiFi ranges from 150 Mbps to 2 Gbps and Data Transfer Speed of LiFi is up to 1 Gbps.
6. Frequency
The frequency of WiFi is 2.4Ghz, 4.9Ghz and 5Ghz and the frequency of LiFi is 10,000 times the radio frequency spectrum.
7. Coverage
The coverage area of WiFi is up to 32 meters and the coverage area of LiFi is up to 10 meters.
8. Components
WiFi has components like Routers, Modems and access points and LiFi has components like LED bulb, LED driver and photo detector.
9. Applications
WiFi is used for browsing the Internet using a WiFi hotspot. LiFi is used for airlines and for exploring the sea.
10. Privacy
Walls in WiFi cannot block any radio waves, so we have to use a lot of techniques for safe data transfer and Light is blocked by Walls in LiFi, so it provides a very secure data transfer.
