Lifi vs wifi, which is the fastest?

The development of science and technology in this age of globalization really can not be dammed. Every day emerging the latest technologies that can help humans in work. Modern humans are increasingly pampered with the presence of technology. Good for education, work and entertainment. In its development, human need fast internet access to facilitate in accessing information. One of the fastest channels of the most widely used saai is Wifi (Wireless Fidelity). But in its development turned out the researchers created a faster internet access channel that was named Lifi (Light Fidelity).


Li-fi is a new method for wireless data transmission in addition to bluetooth and wi-fi is Li-Fi. What is Li-fi? Friends of bloggers may have never heard of the device. In everyday we use the internet, media connection is often used is Wi-fi. What exactly is this li-fi, let's look at the following explanation.

( Lifi System )

The Li-Fi device is a visible method device that enables wireless delivery to connect to the internet network.

For speed issues do not be asked friends, Li-Fi can provide Internet access 100 times faster than devices like wireless connections like Wi-Fi. The speed is about 1 Gbps (Gigabyte per second). How very fast is not it ?? Please read blogger friends again to know more about Li-Fi.

How to use Li-fi is to simply use Li-fi enough using standard light sources such as LED lights, internet connection, and photo detector.

Velmenni use of Li-Fi lights is enabled to transmit data at 1 Gbps. When tested by the theoretical speed up to 224 Gbps .. Waaooooo .... blogger friends Very fast. The creator of this device is Prof. Harald Haas from the University of Edinburgh who demonstrated the technology at the TED (Technology, Entertainment and Design) conference in 2011.

Here are some advantages of using Li-Fi ie.

1. Li-fi is not disturbed as a radio signal, so it can be used on aircraft and other appropriate places.

2. because using a light source such as LEDs, the lamp becomes more efficient 100,000 times so it does not run out quickly.

Although it has advantages, Li-fi also has a disadvantage that can not be used outdoors for example travel long (traveling). Because Li-fi allows interrupt signals, then the initial use of Li-Fi can be restricted to certain places.
