Li-Fi technology is wireless communication technology. The medium of transferring data is light, and that transfers data between two devices. Li-Fi as a term came to be applied in modern times and has had coined by the man called Harald Haas, and he is from Edinburgh.
This is, and the data transfer is at high speeds. The data gets transferred on visible light, UV rays, and infrared rays, and that is all components of light. When something is in its present state, then it should be only LED lights which can carry the light to its final position.
How fast Li-Fi can be? And how Li-Fi can replace Wi-Fi?
Wireless internet is the same as Wi-Fi. The only difference is that wireless signals use radio frequency. It is a safe and sound system. The speed is the only difference between these two methods.
Many international organizations are developing the system over nations. Thus this is a global system. This is an optical wireless system. The light comes from LEDs. There has been an annual growth of 82% between five years in the years subsequent 2k.
This is a technological evaluation. The current passes too quickly and cannot even have had seen by the naked eye. There is no flickering.
The point is not just illumination and not for the transmission of data. There has been a seamless transition from Wi-Fi to Li-Fi.
There does not have to be a direct line of sight for Li-Fi to work. This new technology works well between airline cabins, and this system is more possible in the sense that it prevents hacking.
It solves all your 5G problems. It is very reliable. This technology can also have been in use in cars and automobiles. VR and AR become wireless and free, and that is all that you need to know when preparing to use alternative reality and virtual reality for the Li-fi purpose. The user experience would be impressive overall.
Why light-based LI-Fi technology is better than Radio wave technology?
There are no electromagnetic problems that occur with Li-Fi. Wi-Fi uses radio waves, and Li-Fi uses visible light. This has happened because wireless internet has reached its full capacity. That is not all. Li-Fi is also much cheaper.
The intensity of data is 1000 times than Wi-Fi, and that is the basic about Li-Fi. The latency is much lesser than that found in Wi-Fi.
The first commercially Li-Fi system is already in the public domain. This took place at the world congress of mobiles at Barcelona, and it is a simple consumer product. There has also been a global world talk about the same.
This has been worked upon since the 1800s; the LEDs have are being talked about are single color LEDs. In the future, the speed would go up to 5GB/ s. This helps save battery.
The first such phone came out in 2015. The cost of this phone would be between a few dollars. Light can travel through water, and thus, there is increased mobility.
This connectivity that we are talking about here is called Li-Fi, and it serves devices only in the room. So, this means that light does not go forth ahead of 1000 meters. This works in energy-saving homes and offices.
The obvious benefits are that the system works faster than wireless internet. The frequency is higher than the radio frequency.
How Li-Fi is more secure against piggybacking and squatting?
You do not need to go for piggybacking, you do not have to face interference from outside sources, and there does not impede any other source. It works well even on sensitive electronics, and thus you can use these devices even in sensitive electronics. The area covered is more than the area covered through a wireless router.
Wireless internet leads to piggybacking, which means one person can use the wireless connection of the other, but the same is not possible with Li-Fi. This is also called squatting. The purpose is free to access and without any malicious intent.
Squatting is illegal. Thus there would be no data theft, and the system would not catch any virus. You also cannot use Li-Fi for any illegal activity.
How Li-Fi helps you to make a secured network.
You need user authentication, and you get additional control of your devices, and it allows asset tracking. This also means advanced geo-fencing. It leads to zero to no interference from the surroundings, and the speed is pretty high.
Li-Fi LED light does not interfere in, and you can use the devices outdoors with great ease. Since Li-Fi works on light, therefore, it cannot work in your pocket, and your suit would have to be transparent for this network to work. It is not a line of sight technology.
This technology is secure, and you usually need to shut the door to start using this Li-Fi technology. There is the high-speed transmission, and it works with both uplink and downlink. The whole idea of light linking the two devices is that which is very appealing.
The German scientist is well known for his work on the Li-Fi. The best part about the system is that it can draw light from street lamps and till auto-pilot cars. Li-Fi technology has evolved since ages.
The system has to have a transmission and receiver. The communication is in the form of binary codes. Since the buffering done gets fast, therefore, it is preferred to use Li-Fi with the internet.
You would not be able to use this Li-Fi with dim lights. These Li-Fi devices can are in use with elegant lighting. It can also be used for transmission underwater.
Blind people can use this for reading maps. It is suitable for transportation. It can also come into industrial areas. It has good features.
Last, of all, Li-Fi stands for light fidelity and visible light communications. The speed is pretty neat, and thus you get a world leader in high brightness internet connection.
The frequency is so right that it is not even visible to the naked eye. This means high safety with low power. It is with these technologies that which means for cheaper internet in aircraft. I hope it was an exciting read.
