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:
NICTA (National ICT Australia Ltd)
IEEE (Institute of Electrical and Electronics Engineers)
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.
GI-Fi works within the very high dense environment.
Li-Fi works with the high density environment.
Gi-Fi is very cheap, costs only 10 $.
Li-Fi is cheaper compared to Wi-Fi as it uses light.
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 is less than 2MW (milli watts).
Power Consumption is upto 1 MW (milli watts).
Mobile phones, home devices, electronics, etc.
Hospital, vehicle and transportation, aviation, etc.
