What is main difference between Li-fi and Wi-fi?

Definition of these technology

The word Li-Fi is an acronym for Light-Fidelity. In 2011, Professor Harald Haas discovered Li-Fi.

Works on Li-Fi (VLC - "Visible Light Communication") technology.



The term Wi-Fi is an acronym for Wireless Fidelity.

Wi-Fi is a popular wireless networking technology. Which uses wireless waves to provide high speed internet and network connections. Wi-Fi is a strategy for connecting electrical devices in a wireless way. This is the standard set by IEEE (Institute of Electrical & Electronics Engineers) 802.11 for Wireless Local Area Network (WLAN).Its area is a room, building or a few km. May be across the area. Li-Fi technology is like Wi-Fi without its communication system.

Comparison between Li-Fi technology and Wi-Fi


Waves act as a medium in the field of Wi-Fi. Light works as a medium in Li-Fi field. Li-Fi transmits data through light in the communication system. The frequency of Li-Fi is 10,000 times higher than that of Wi-Fi. Since Li-Fi runs on light technology, it is not possible to go through the walls of the signal room. Because light cannot penetrate dense objects.Wi-Fi signals spread evenly around but since Li-Fi is light, it does not spread evenly around. Here you can target the direction of light to your liking. The result will help to get the maximum signal. Many studies have shown that wireless signals contain radiation. But since Li-Fi runs on light, there is no risk of radiation.


So now let's talk about what is the exact advantages and disadvantages of Li-Fi technology:


1. When it comes to the benefits of Li-Fi technology, the first thing to say is its speed. Using this technology you can get speeds up to 100 Gbps. And it has been thoroughly tested. Moreover, the frequency of Wi-Fi is 10,000 times higher than that of Wi-Fi.

2. Since Li-Fi frequency is much higher than Wi--fi, it has the ability to control many users at once. This means that even if the number of users increases, there will be no connection error between them. If we talk about WiFi, you will see that if one user uses more bandwidth then the connection of the other user is completed slowly. But this technology will not be like that.

3. Wi-Fi or wireless signals can penetrate your walls. As a result, your neighbors get the signal when you use Wi-Fi. And since Li-Fi runs on light technology, the signal is not likely to go anywhere through the walls of your house. Because we know that light cannot penetrate dense objects. So you will use the internet with this technology at home and no one's father will have the ability to detect your signal.

4. Wireless signals are actually intercepted. This means that when you turn on the WiFi router, its signal spreads evenly around. Now if that signal doesn't come to you, it's useless. Because the more signals come to you, the more signals will spread around you. But since life is light, you can target it to your liking. This will allow you to get the most signals and increase your data density. You will be able to exchange high speed data at maximum signal.



So these were the special advantages of using this technology. There are many more benefits you can get when you use it. Let's discuss some misconceptions about this technology. With the advent of technology, many misconceptions have spread around. Take a look at some of the misconceptions you already have.



The future of  Li-Fi revolution :

Life is a completely new technology. So maybe it won’t be available or available for use right now. Maybe in the next 10 years, the use of Li-fi will start in full swing. The Li-fi device may have been pre-installed on the smartphone or tablet at that time. However, I can clearly say that in the coming days, Wi-Fi will be able to take the place of Wi-Fi.

The range of Li-fi will not be much. Because it will be on your head, so you have to use Li-Fi from a certain place. However, you can rest assured about high speed data exchange.

Hope I you got the answer.

What are the things to consider when buying a WiFi or broadband router for home, office, park and restaurant ?

Today we talk about What are the things to consider when buying a WiFi or broadband router for home, office, park and restaurant .I never like huge introduction about any topic . I always like very shortly introduce any-things to my viewers without any-type boring .So let's began the leanrning :- 1. Decide in advance how many devices you will use. 2. Decide how much space you need coverage. 3. Understand the structure of your home. WiFi signals become weak to penetrate the walls. That is why good coverage is not available. If you have a lot of walls in your house and you want to get coverage in the whole house, then you need a router with high power and wall penetration feature. 4. Decide what features you need in addition to the internet connection. Such as: - 4.1 3G 4G Modem Support- There are many routers that can use the modem. Those routers have a USB port and a one port so that broadband lines can be used. But remember that the modem must have the ability to auto-connect. Not...

What should the processor look at?

The things that we all should keep an eye on are the processor or not; 1. Clock speed 2. Number of course 3. cache memory 4. FBS 1. Clock Speed: It is also called GH2. All processors are written on. Clock speed means how fast your computer can work. That's what this signal means. The speed of the processor is known through this clock speed, how fast the calculation can be done. 2. Number of Cores: The more cores the processor has, the faster the processor can work. If I give an example to explain the matter, I hope you can understand it very easily. Suppose if a person had many hands, then he could do many things at the same time. That is, if we go to the market and buy a smartphone, then we will see what the configurations of the phone are. If we look closely at the configuration of the smartphone, we will see that Dual Core Processor, Quad Core Processor, Octa core processor, Hexa core processor, Deca core processor. This means that the dual core processor has two arms or cores, ...

What is transmission media? Introduction to different types of data transmission cables

Transmission media: When a PC communicates or wants to communicate with another PC, it has to take the help of some transmission media. The most commonly used media in the network are twisted pair cable, coaxial cable, fiber optic cable. Nowadays, the use of optical fiber is increasing greatly. Radio wave, microwave and infrared technologies are prominent among wireless media. Among these mediums, optical fiber has the highest data transfer speed. The type of medium used in a network depends on the type and location of that network. The connection system for exchanging information between the sender and the remote receiving end is called a channel. The means or methods used to implement the channel are called media. such as-- (i) Cable or wire. (ii) Common telephone lines. (ii) Radio waves. (iv) Microwave. (v) Geo-satellite systems etc. Cable or Wire: Cable is an important medium in data communication. Cables are generally used for data transfer over short range networking such as LAN...
