What are the differences between Li-Fi and Wi-Fi?

Over the years, we have experienced several technologies in the world that have made our ways of calculating, communicating, and doing things easier. One such technology is the network. Networks can be connected using cables and wirelessly. For a very long time, the Wireless network has been the most popular type of network. These are some of the networks that Internet Service Providers make available for those who want to connect to the Internet. You can always read reviews about broadband internet services on US-Reviews to know the technologies the Internet Service Provider you want to patronize uses.

In recent times, you might have been hearing about 2 types of networks that send data wirelessly namely the Li-Fi and Wi-Fi. This article will discuss the differences between Li-Fi and Wi-Fi.

Meaning

Li-Fi is an abbreviation for Light Fidelity. On the other hand, Wi-Fi is an abbreviation for Wireless Fidelity.

Invention

Professor Harald Haas coined Li-Fi in the year 2011. This is as opposed to Wi-Fi which was invented some 20 years earlier. The Wi-Fi was invented in 1991 by the NCR Corporation.

Method of operation

The method of operation for Li-Fi is also different from the method of operation for Wi-Fi. While the transmission of data in Li-Fi is done through light signals from LED bulbs, the transmission of data in Wi-Fi is done through radio waves from a Wi-Fi router.

Device compliance

The devices that can transmit data through Li-Fi and Wi-Fi are those that are compliant with different standards. For Li-Fi, the devices have to be IrDA compliant devices. On the other hand, the devices for Wi-Fi have to be compliant with the WLAN 802.11/b/g/n/ac/d standard.

Speed of data transfer

The speed for transferring data is one of the major things we look at when it comes to networks. Li-Fi can transmit about a speed of about 1 GigaByte Per Second. On the other hand, Wi-Fi devices transfer data at a speed that ranges between 150 MegaByte to 2 GigaByte Per second.

Frequency

Li-Fi and Wi-Fi also use different frequencies. The frequency for Li-Fi is about 10,000 times the spectrum of the radio frequency. Wi-Fi, on the other hand, uses the 2.4Ghz, 4.9Ghz, and 5Ghz frequencies.

Coverage

The distance that can be covered by the network is also very important. The distance that is covered by Li-Fi is around 10 meters. On the other hand, the Wi-Fi covers an area of around 32 meters. Furthermore, there are Wi-Fi repeaters that you can use to extend the range. The coverage is important because, from the point where the Wireless is being transmitted, only devices within that coverage area will be able to connect successfully to the network.

Components

The components that you will need to set up a Li-Fi and Wi-Fi network are different. The components for the Li-Fi network include an LED bulb, photodetector, and LED driver. On the other hand, the components for setting up a Wi-Fi network include routers, access points, and modems.

Applications

The applications for Li-Fi and Wi-Fi are different. While Li-Fi is majorly used in explorations under the sea and airlines, Wi-Fi is used for connecting to a hotspot to either browse the Internet or share information and hardware.
