What does the ‘Fi’ stand for?
>>54521035
Doesn't matter. It's 100 times faster than Wi-Fi. You don't have to worry about emissions leakage which means nobody can fly a drone carrying a smartphone around your corporate building to find an unsecured port. It works underwater better than lasers. It doesn't intrude into the already crowded radio spectrum like Wi-Fi does.
It'll be used. We'll use it inside and at night, and then during the day we'll use Wi-Fi.
>>54521099
Fidelity. Not joking, you can look it up--full name is Light Fidelity, and yes they did pick it so that it would sound like Wi-Fi when shortened.
>>54521092
This is actually considered a plus by most because it lets you easily limit access to your network.

>>54521182
>MOOOOOM I ALREADY TOLD YOU TO NOT TURN OFF THE LIGHTS AT 3AM WHILE I'M PWNING THESE NOOBS ONLINE
>>54521182
The lights don't have to be emitting enough light to see with to be transferring data. It would be trivial to set the light switch so that it would just dim them, and energy use at that point is also trivial.
Also

>>54521180
Same thing, "fidelity"
>>54521180
https://en.wikipedia.org/wiki/Wi-Fi#Etymology
Nothing really, it just was supposed to sound like HiFi
>>54521096
Are you fucking serious? That's literally the entire purpose of greentext, retard.
>>54521242
>>54521252
But what does “Wireless fidelity” mean? Like who the fuck came up with this? It makes no sense.
It could be really cool in light fixtures or for something like vr
>>54521023
wifi
>single device gets signal around the house
lifi
>mess around with the existing cable setup
>several expensive LED lights per room
>doesn't work outdoors so public hotspots won't be a thing anymore
>seizure risk
Well, someone will benefit from this but it won't be the consumer
>>54521300
That it works with existing light fixtures is a huge potential draw for businesses since it won't cost all that much to upgrade their buildings with it. Some tinted windows if they don't have them, some new lightbulbs, and suddenly their server's speed is the new bottleneck.
>>54521334
Except most networks are wired
>>54521324
>mess around with the existing cable setup
Maybe. It's been suggested that there's ways around that.
>several expensive LED lights per room
You only need 1/room and at $8 or less per light that's several of them prior to you reaching the cost of a wifi router. Don't forget that these also do double duty as your house lights and last for 10 or so years before needing replacing.
>doesn't work outdoors so public hotspots won't be a thing anymore
Just use wifi in the day. It works at night.
>seizure risk
No. The flickering is far too fast to be detected by the human eye. Do you even realize how dimmable LEDs work? When you dim them they flicker very fast and our eyes just see less overall light, they aren't drawing less power from the battery. And those have been around for years now without causing any seizures.

>using lights

no thanks, lights are fucking shit.
>>54521023
>read wiki about lifi
>read quote " It is so far measured to be about 100 times faster than some Wi-Fi implementations, reaching speeds of 224 gigabits per second.[2]"
>follow citation
>The Li-Fi technology used by Velmenni in the pilots is able to send data at up to 1GBps - more than 100-times faster than current Wi-Fi technologies
>"The link operates over ~3 m range at 224 Gb/s (6 x 37.4 Gb/s) and 112 Gb/s (3 x 37.4 Gb/s) with a wide field of view (FOV) of 60° and 36°, respectively. To the best of our knowledge, this is the first demonstration of a wireless link of this type with a FOV that offers practical room-scale coverage," the report states.
Yeah, current Wifi tech is limited to 10mbit/sec...
>>54521447
This thing was made by mexicants or some shit. It's just a meme.
>>54521150
But light travels further than radio signals. All I have to do is get one good cam feed in a high clearance facility and I'll be able to get into their network
>>54521483
How are you planning to do that? They can have radio frequency sniffers that won't pick up their own shit to check for anything phoning home.
>>54521150

You do know both are the same thing, right ?
>>54521526
>needing a constant LoS connection
Just imagine a tiny little man inside your light bulb doing this and your device picks it up
Does it matter? 802.11ac maxes out my symmetric 200mb connection. Unless the latency on Li-Fi is amazing, the bottleneck will always be the pipe to the ISP
>>54521037
Seriously laughing way too hard now
>>54521074
It's a cheetah you uncultured swine

What's the point of faster local connections if the overarching infrastructure can't even meet the slow version? Fuck American ips.
>>54521580
Well something to consider is that typically there is 1 wifi transmitter to cover medium to large area.
The further away you are the slower things get, with LiFi the transmitters would always be nearby as light sources.
Something to maybe think about.
>>54521632
>What are LANs used for?
>>54521696
how's a mobile device gonna bottleneck on a LAN
>>54521766
When you're working inside a LAN you'll ideally only be limited by the speed of your storage mediums. Your 50Mbps WAN connection isn't being used when you're streaming a 4k video from your desktop to something hooked up to your TV.

kek
>>54521526
Actually, they already have it where it is able to pick up the signal bounced off a wall. So walking between the device and the transmitter would do shit all to stop the data flow.

What ever happened to 60ghz WiFi? Doesn't that have all the same advantages as lifi but without being screwed up by lighting? Also it has already been implemented and no one seems to be adopting it and it doesn't require radically different hardware from what is already widely used.

It is only one way: light goes from light bulb to computer, not other way around.
They already implemented this in dubai.

because you couldn't get a life, they invented lifi

Does it really need the lights to be on? I will probs never use it then

>>54524526
You can transmit back from a smartphone with a special screen, which costs only a few dollars, and can be swapped out relatively easily. And smartphones can use their cameras to receive. They've tested this by putting two smartphones with screens touching and transferring gigs of data between them in seconds.
>>54524575
Just have the lights dim to where you can't see them, but are still transmitting, dumbass.
>>54524605
The lights have to be on but can be at such a low level of brightness (due to flickering very fast) that you don't see them.

It's a meme you dip!
Who cares really? Wi-fi is already incredibly fast as it is, many people don't even reach the speeds that their routers are actually capable of. This will mainly be useful for big enterprise buildings, where network interference and huge network traffic is there, but even then I've seen wi-fi routers work just fine there. Plus it's going to be unstable, unreliable and a hundred times more expensive than wi-fi, just like any new technology is at launch. It also seems to be at very, very early stages of development, I'd give it around 10 to 20 years before you see ISPs using this and mass production of li-fi hardware.

It lacks all the convenience of wifi, at this point you should just use a wired connection.
Eh, at least here in Burgerland, not really all that excited. Sure, connections on the local network will be a lot faster, but Internet speeds won't be all that better, thanks to shitty ISPs.
