Last year I wrote about LiFi, how it can play a role in densification and beyond-5G. LiFi (sometimes written as Li-Fi but I believe LiFi is the correct way to write it) has been in news recently because of world's first backhaul trial with an ordinary solar cell as data receiver in Orkney.
Land Mobile has a good write up on this here.Immensely proud of the @LRDC @kikepoves team for the successful launch of the world's first #LiFi backhaul trial with an ordinary solar cell as data receiver. Thanks to @DCMS @5GRuralFirst #5G project. This means people on Graemsay (Orkney) can now watch 4k TV! pic.twitter.com/SkQw8gEn1M— Harald Haas (@dlarah15) July 4, 2019
There is also misunderstanding sometime about different types of light communications being referred to as LiFi. The picture above shows difference between OCC (Optical Camera Communications), VLC (Visible Light Communications), LiFi & FSO (Free Space Optics).
Rather than talk too much about the technology, I will point you in the direction of this excellent article, 'LiFi is a paradigm-shifting 5G technology' by Harald Haas. This is available freely here.
There is also a recent video from IOP LiFi Launch with pureLiFi on YouTube. The audio is slightly faint but it's full of useful information. Embedded below:Tuncer Baykas talking about #LiFi 802.11bb activities at #PIMRC 2019. He makes the point that the PHY layer will be based on legacy 802.11ax PHY layers - this is greatly appreciated as we don‘t need to reinvent the wheel! pic.twitter.com/ucaZ8uuXSa— Harald Haas (@dlarah15) September 11, 2019
