Difference between LiFi and WiFi

Hello readers welcome to the new post. In this post, we will discuss the difference between LiFi and WiFi. These two terms are used to transmit the data without the use of wires. In Wifi routers Radiofrequency is used for data transmission and in LIFi LED bulbs and light signals are used for transferring and receiving the data.

In this post, we will cover all the details of these two networks and find their differences. So let’s get started Difference between LiFi and WiFi.

What is WIFI

WiFi full form is wireless fidelity and uses a wireless system to transmit the data. it is compatible with IEEE 802.11 standards to manage the wireless internet system

The transmission of data through wire is difficult to process since its installation is not easy that is why WIFI is most commonly used to provide data transmission through wireless systems.
It works similarly to the local area network in the absence of wires.
Different computer-based modules like laptops, tablets mobile phones Smart TVs, and digital cameras work on the WIFI
The data transfer rate is high speed with the use of WIFI to transmit the data and files among the different computing devices.
Through WIFI different devices can link through wireless connections among the devices and the Internet.

What is LiFI

LIFI full form is light fidelity which uses Light signals and LED bulbs for signal transmission between two points.
For the last many years, light has been working as the main part of illuminating devices at our homes schools colleges and offices
Nowadays there are innovations in the light industry that LEDs not only provide light but are also used for communication.
LED works as a wireless communication system that can regulate computers mobile phones and different electronic devices in all over the world

WIFI Features

The main functions of WIFI are explained here
It can transmit data from 2.4 gigahertz to five gigahertz with less security issues than the LIFI system
This technology is considered cheaper than others
Its installation on any computer is easy thanks to the use of LAN.
It is also used to configure laptops, printers, game consoles
It is mostly used for short distances as its signal covers a distance of three hundred feet

WIFI Vs LIFI

LIFI

It was invented by Professor Harald Hass in 2011
It used an LED bulb for the transmission of data
It is compatible with IrDA technology
It can transfer about one giga data
it follows the IEEE 802.15.7 standard
Walls are used to secure the data
it consists of features of unlimited bandwidth
its frequency is 10, 000 times the frequency spectrum of the radio
It can cover data up to ten meters
Uses less power than the WIFI
its prices are lower than the WIFI
Its common applications are in airline undersea communications

WIFI

WIFI was invented by NCR corporation in 1991
It used routers and radio waves for signal transmission
the technology used is WLAN 802.11/b/g/n/ac/d standard-compliant devices
it can transfer data rate from 150Mbps to 2Gb
It follows the IEEE 802.11 standard
it has a limited value of bandwidth
its frequency ranges are 2.4Ghz, 4.9Ghz and 5Ghz
it can transmit data up to thirty-two meters
It uses more power than the LIFI
it used in fewer dens conditions
Its prices are high
Common applications are internet browsing

LIFI Advantages

it has unlimited bandwidth
uses less power than wifi
it is a secure module
Its operating speed is high and effective
It is free from electromagnetic interference

LIFI Disadvantages

It interferes with the light of the sun, normal bulbs, etc
its range is small
Its starting prices are high
It can not pass through walls

Is LiFi cheaper than WiFi?

LED light bulbs release light pulses that cannot be detected by the human eye and in those released pulses, data can move to and from the receiver. It increases the speed and bandwidth of WiFI, 3G, and 4G. That means it is faster as compared to WiFI. It is lower cost than Wi-Fi.

Can LiFi be used as WiFi?

The use of LiFI is like WiFI in that provides different features, Like other wireless communications systems, LiFI is used in different uses for example internet purposes, phone-to-phone communication, etc.

What is the disadvantage of LiFi?

it can move in the range of 10 to 20Gbps and can also for higher. Its disadvantage is that light does not have features to pass through opaque obstacles like walls, which makes its range limited.

Is LiFi safer than WiFi?

LiFI is secure as compared to WiFI, lifi provides low chances for interference as compared to the radio frequency that powers WiFI. LiFi wireless communication can done through ocean water. LiFI has features to operate in areas where high density exists.

Can LiFi be used in sunlight?

LiFi can work in daylight and also in direct sunlight since modulated light can detected. Lifi based on the detection of fast variations for light intensity and not through slowly changing levels resulted in natural obstacles in daylight

Is LiFi long range?

Life uses is restricted by the distance light can pass through water. The amount of light does not pass more than 200 meters.

Which countries are using LiFi technology?

U.S.; Canada; Mexico; U.K.;South Korea; Brazil; Saudi Arabia; South Africa; Turkey Germany; France; Italy; Spain; China; India; Japan;

What are the disadvantages of LiFi?

if there is no light source you are not able to use the internet.
its signal range is limited since visible light does not pass through walls which is the main medium for LIFI working
