History of LiFi
Li-Fi (Light Fidelity) is invented by Prof. Harald Haas in 2011. Li-Fi is a 5th generation wireless data transmission technology which transfer data using Light Emitting Diode (LED)s
Migrating from WiFi to LiFi
Usage of wireless traffic is getting to increase from year to year. Compound annual growth rate (CAGR) of wireless traffic over the past decade is 60%. According to this increasingly rate, Wi-Fi will have a 0.3 THz demand of bandwidth in next 20 years. However, this is impossible with the available RF bandwidth in RF system. (Haas, 2018).
What is its Capability
The first tested Li-Fi version transfers data using IEEE 802.15.7 protocol. (Haas, 2018) Because of this higher bandwidth and parallel transmission method Li-Fi can transfer data in a rate of 6 Gbps from the implementation. (Haas, 2015).
