Difference Between Gi-Fi and Li-Fi

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. |
