IEEE finally brings Li-Fi
GS Paper - 3 (ICT)
Dr. Harald Haas (Professor of Mobile Communications at the University of Edinburgh) touted as the father of Li-Fi (Light Fidelity) was the first to coin this term in 2011. It is capable of delivering almost 100X times faster internet speed compared to the current crop of Wi-Fi routers. After two decades, the Institute of Electrical and Electronics Engineers (IEEE) has formally announced the 'IEEE 802.11bb’ Light Communication Global standard.
About Li-Fi
Li-Fi works on optical wireless communications (OWC) technology. Unlike Wi-Fi routers, which use Radio Frequencies to transmit data, Li-Fi devices (with light-emitting diodes: LEDs) will deliver data through light or infrared light.
Li-Fi devices will be able to deliver internet speed close to 224 Gb per second. With such speed, users can download close to 20 high-resolution movies in a second.
However, the hardware capable of delivering such speed is yet to be developed. For now, with the IEEE 802.11bb standard specification, the speed is limited to 9.6Gbps.
For now, developers are working to optimise mixed use of Wi-Fi and Li-Fi at homes and offices.
It should be noted that Li-Fi has one disadvantage, it can't connect to devices in a different room separated by walls. Both the device and LED Li-Fi router has to be in the line of sight for internet support
It not only offers lightning-fast internet speed and also is said to be more reliable and safer compared to Wi-Fi and 5G cellular connectivity, as it is almost impossible to tap light from a far distance.
Besides connectivity with phones and computers, Li-Fi comes in handy in connecting with Internet-of-Things(IoT)-based smart home appliances for instant connection.
With the advancement in technology in the future, there is a possibility of companies coming up with multi-functional bulbs that support Li-Fi in every room of the office or the house for super-fast connectivity.
