A few months ago, I started working on TechKnowledge Technology Stories , a series of videos looking at how technology has evolved over the years and how it will continue to evolve in the future. The latest video is looking at connectivity in general. It is embedded below and the slides could be obtained from 3G4G page here .

I have been writing about LiFi and other light based communications for a while but it looks like these are finally being standardised and have a potential to be used in commercial devices for communications. The first thing to mention here is that like there are different brand names for Wi-Fi (like Wi-Fi 5, Wi-Fi 6, etc.), we probably need different names for LiFi. In fact I am not even sure if we write LiFi as one word or Li-Fi. LiFi Tech News describes the technologies as follows: ITU-T G.9991 standard is the 1st LiFi standard specifying the system architecture, physical (PHY) layer and data link layer (DLL) for high-speed indoor LiFi transceivers, the LiFi access points within LED and infrared lamps. There are also at least 3 IEEE standards that are being developed to bring LiFi to the mass market. These are the IEEE 802.11bb, IEEE 802.15.7 and IEEE 802.15.13. IEEE 802.11bb defines one medium access control (MAC) and several physical layer (PHY) specifications for wireless conn
