Difference Between Gi-Fi and Li-Fi

Gigabit Fidelity (Gi-Fi): It is the absolute first transmitter cum beneficiary installed on a chip. It is manufactured using the CMOS (Complementary metal-oxide-semiconductor) procedure which works at 60 GHz. It will permit video transfer at the pace of 5 gigabits per second, which is higher than the present Maximum transfer rate of wireless fidelity, at 10% Of the expense. It was developed at NICTA (National ICT Australia Ltd) in Melbourne, Australia. This innovation was decided to be built in the frequency range of 57-64 GHz by the NICTA researchers. In a closed environment, the Accessible 7 GHz of range resulted in a data rate Of 5 GHz per second, typically within 10 meters Range. It works with the IEEE 802.15.3C band.

Light Fidelity (LiFi): It is a wireless optical networking technology that uses visible light from LED’s for data transmission. Li-Fi has created a new revolution in wireless communication. A German physicist, Herald Hass keeps on wowing the world with the revelation of data transfer using light. Li-Fi allows an electronic device for connecting to the internet with no wire. It is more secure than wireless fidelity based on the spread of the signal. Li-Fi uses visible light and communication and it is faster compared to radio-waves which is 250 times faster compared to any other broadband.

Below is a table of differences between Gi-Fi and Li-Fi:

Based on	Gi-Fi	Li-Fi
Specification authority	NICTA (National ICT Australia Ltd)	IEEE (Institute of Electrical and Electronics Engineers)
Operation	GI-Fi technology transmits the data over the air using the millimeter waves.	Li-Fi transmits data using light intensity modulation.
Data transfer rate	Provides the speed upto 5 Gbps, and more.	Provides the speed upto 1 Gbps.
Frequency of operation	Li-Fi can achieve the frequency of operation around 60 GHz.	Li-Fi can achieve the frequency of operation upto 50 THz.
Coverage Range or distance	GI-Fi range up to 10 meters in particular.	Li-Fi systems can maximum range up to 100 meters depending upon the light intensity and range of that LED.
Data Density	GI-Fi works within the very high dense environment.	Li-Fi works with the high density environment.
Cost	Gi-Fi is very cheap, costs only 10 $.	Li-Fi is cheaper compared to Wi-Fi as it uses light.
Security	Data transfer is less secured compared to Li-Fi.	Li-Fi provides secure data transfer due to the light blocked by the walls.
Power Consumption	Power Consumption is less than 2MW (milli watts).	Power Consumption is upto 1 MW (milli watts).
Primary Devices	Mobile phones, home devices, electronics, etc.	Hospital, vehicle and transportation, aviation, etc.
