Li-Fi - A Best Wireless Communication

The Li-Fi(light fedility) technology was proposed by German scientist namely Harald Hass. The main function of this LiFi technology is to transmit the data via light. This technology offers many benefits over Wi-Fi technology such as high bandwidth, ease of use, efficiency, and safety. These systems can communicate from street lights to auto-piloted cars with the help of their headlights As the speed of the light is more, data communication speed is faster in that system. The main feature of this technology includes fully networked, bidirectional and high-speed wireless communication. For obtaining better speed, efficiency, Li-Fi technology has evolved. The data transmission in this technology can be done using light because the light intensity changes quicker than the human eye. The range of data transmission in Li-Fi technology is 100 times faster than that of Wi-Fi. Hence, this technology can be implemented for speed data access for the laptops, and gadgets that will be transmitted during the beam in a room.

What is Li-Fi

Li-Fi is a VLC(visible light communications) system and the speed of this system is very high. This uses normal LEDs to allow the data to transfer and increase the speed up to 200 Gigabites/sec. The data transmission can be done via illumination(brightening something). The devices used for Li-Fi technology are bright LEDs. The ON/Off activity of LEDs permits data transmission in the form of binary codes.

Applications of Li-Fi technology

The Li-Fi router applications are unlimited for wireless communication. Few applications of Li-Fi technology are listed below:

• Traffic Management and Road Safety

• Medical Applications

• Aviation

• Underwater communication

• Interior map-reading system for blind people

• In dangerous Environments or In Sensitive regions

• Transportations

• Industrial Areas

We have Wi-Fi technology. Then why Li-Fi

• The speed of Li-Fi is up to 10Gbps whereas Wi-Fi is limited to 150Mbps.

• Security of Li-Fi is higher than Wi-Fi.

• Power availability of Li-Fi is more than Wi-Fi.

• Ecological impact of Li-F is very less than Wi-Fi.

• Li-Fi is cheaper than Wi-Fi.

• The data density of LI-Fi technology is higher than Wi-Fi.

Advantages of Li-Fi technology

• The speed of the Li-Fi is very high, and we can watch the videos without buffering.

• The light of the Li-Fi doesn’t run through the partition. So, it is safe and hacking is not possible.

• Li-Fi technology is Risk free technology. Li-Fi utilizes light waves which are harmless.

• The data transfer is more protected.

Disadvantages of Li-Fi technology

• The main problem is how the receiver will send the data back to the transmitter section.

• It doesn’t work in the dim areas.

• Sunlight in the lane of communication may cause intermission in the transmission.
