Won't light based wi-fi have problems penetrating walls? I did not see that point brought up in the article.
Its sort of indirectly mentioned when they mention the security benefits of lifi, as in order to effectively have access to it, you would need access to the room.
The tech isnt meant to completely replace wifi, it just jas some benefits in certain use cases over wifi.
it's a feature, not a bug!
I could see this as a huge upgrade for a WISP.
It was brought up in the article as better security.
"Moreover “Light’s line-of-sight propagation enhances security by preventing wall penetration, reducing jamming and eavesdropping risks, and enabling centimetre-precision indoor navigation,” says Shultz."
Pretty cool, especially considering how it's been shown that WiFi can be used to pretty accurately determine the position and number of people in a room with AI.
Just knock them all down. Isn't open floor plan the current trend? 😉
The article discusses this, it's a benefit. They use the example of reusing your overhead light as a lifi broadcast. That way it's more secure because it doesn't penetrate through walls. You could use something like a desktop lamp be the router, not not have to worry about the signal leaving the room.
The article calling it a benefit doesn't make it one.
Well it certainly can be a benefit to have super fast wireless data that doesn't leave the room. Especially for businesses that work with huge amounts of sensitive data. Probably not as useful for home use though
Gotta be a big room for the that, otherwise just wire everything. Unless they want a clean aesthetic in their business, I guess.
It will have all the same deficiencies your eyes do. If you can't see through a wall, then neither can "Li-Fi".
From the article:
It seems like this is technology more for 1 way communication with devices over a large completely open area like a warehouse
