- What if we could use existing technologies to provide Internet access to the more than 4 billion people living in places where the infrastructure can't support it? Using off-the-shelf LEDs and solar cells, Harald Haas and his team have pioneered a new technology that transmits data using light, and it may just be the key to bridging the digital divide. Take a look at what the future of the Internet could look like.

But you need unobstructed line of sight. How practical is that? WiFi radio can go through walls.
+Overonator the title is misleading. it has different use-cases. LiFi does not replace WiFi
+Overonator something like this would be great for LAN and stuff like that. And my computer sits right next to the router so for someone like me, this works out perfect
+Overonator mix it up with "trillion frames per second" ted video :P
+ej1250 Don't go wireless if you can wire yourself directly to your router. A wired connection is faster and way more power efficient.
MrC0MPUT3R yeah i already do that. but i was just explaining that this invention would be good for people who has their computer close to the router. just replace the router with the solar reciever. it should end up being more cost efficient compared to a router that's constantly on while the PC is off
But you can only receive data? How do you request data?
+JamesB00n Yes, rather than local service to customer I see this more as a long distance data transport to local stations and then another tech for local transfer.
+JamesB00n Have a laser in the roof of your house pointing back at the source (use the solar panel to power it ! XD). The problem of course would be making sure it never moves, because if it miss-aligns then you wouldn't be able to send data (maybe that could be solved using a network of senders and recievers on the top of each house on the network).
+JamesB00n Absolutely no upload? x)
+iluan Hernandez a weaker more dispersing light you be used to locate the two nodes and they could auto align by using some kind of search algorithm.
just what I was thinking.
Would be a great technology to improve communication between cars (especially autonomous) via the headlights and braking lights. Cars could easily determine the car in front of them and communicate if that car approaches an obstacle for example. The speed of data transmission would be way faster than what is possible with mobile data at the moment. This would make autonomous driving more safe I believe.
True
This reminds me of the in store price correction systems. Stores rigged up their lighting to pulse signals and electronic price tags picked up the flicker so prices could be updated for specific products or across the store with a minimum of wiring. The price displays were powered and set by the lighting. No wires or signals required.
Calm down people,its still a prototype, you remember a prototype of phone years ago?
from what I can see,it might be useful in many ways,lets wait for few years.
It's true it's not practical at all.
How is the laser been gonna focus on a moving solar cell?
Not only that it only receives, can't send.
So imo is basically useless.
It's still cool none the less, just not at all
Practical, and I don't think it will be, not any time soon.
+Yukino Takada and us saying how it is deficient to the maker isn't something that the maker can't use?! at the very least he should address them during presentations
Too bad this is existing technology that's been morphed to make it seem unique.
Too bad this is existing technology that's been morphed to make it seem unique.
I can't remember the prototype for a phone... late 19th century is a little too far back ;-)
I see that the drawbacks of this idea have already been commented on by a number of people. Though, still, it is an interesting concept.
Physics Videos by Eugene Khutoryansky hello
Physics Videos by Eugene Khutoryansky this what we call it nircable FO.... but its still not time .. we need more other support tech 1st ..maybe 50 year in future
ur videos are really best please continue making
Why did that request comment just disappear?
It no going to work as internet data transfer because resive and sending is also needed
Not only resive?!!!
Got it the device can't send data through solar panel to led light 🤣🤣🤣😎😎😊😉
@5:36 . Anyone else notice that the 'fog' did not cover the entire panel?
masses of hot air made the fog stay that way
Does the fog cover the entire sun
@@anuragtitus1379 yes.
It's disadvantage can also be its advantage.
Advantage/Disadvantage: You need clear line of site from the transmitter to the receiver. This means you guarantee that only people, in the room for example, can see the connection. I believe this can be either an inconvenience or a security feature depending on your goals.
Pure Advantage: Because it is using much higher frequency light than WiFi the maximum connection speed limit is far higher than WiFi's.
Wrt the disadvantage, i am sorry i am 7 years late but there is hope with one concept as a potential solution : Reflection of Light
this project is becoming true
This is an amazing concept. As far as long distance or constant light exposure areas, this would change everything. I wonder how they are going to try and circumvent the problem of physical blockage.
The good thing about this is that you can use the current arquitecture, PLC, Power Line Communication. You can use the residential ac wires as your conductor and have all lights as transmitters
FANTASTIC IDEA. WORLD CHANGING AND ONE OF THE BEST IDEAS I'VE SEEN IN THE LAST 20 YEARS. ABSOLUTELY GREAT IDEA, MAN. CONGRATS.
Thnx Mr. Hass it's been an honour to watch your video .recently me with my friends made a lifi project to transmit data using mic it works but also we can't expend distance between transmitter and receiver if you help us we will glad. Finally I must say it is a revolution and if it applicable there will be no problem in data steaming anywhere.
Fascinating! The demonstration is very reminiscent of tabletop scientific demonstrations & experiments done in the 18th and 19th centuries. It should be extremely interesting to see where this technology goes in the near future.
The challenge of sending information from your smart device _back to_ the Net via Li-fi will be daunting.
Exactly what Fibre Optics use to transfer at high speeds. Uses Light to transfer.
But he wants LI-FI. LOL
This definitely has potential! What he showed with the handkerchief means we could have satellites in space spreading a radius of lasers, and even when it's cloudy, you'd still get the stream! And in a storm, we would all lose power anyways.
Or we just use antennas, you know.... something that works. I just can't understand how you would focus a Laser over such long distances. I mean air molecules would most likely disturb the signal with all the umidity or heat. I don't want to be rude but to me it sounds like a silly idea.
Comments Section = Facepalm... Li-Fi is, in no way, Replacing Wi-Fi. They have very different uses. Lifi can only receive data.. at the moment.. We can use this technology to bring internet around the world; not for upload, but download. Imagine transmitting the encyclopedia britanica, and any digitized book, to schools in the Congo for virtually no cost. I for one can't wait until we develop more solar-based technology. Maybe then we'll start investing in it because apparently global warming and dissapearing landmass is not reason enough. Maybe if we offer people faster internet, they'll consider it.
+MrCheezyCrack And without being able to send a single request packet out to retrieve said encyclopedia/books, how would this one way internet connection provide any benefit to anything. Do you know how TCP/IP works? This thing's use cases are better suited to long distance laser ISP infrastructure in under-developed countries to allow at least a local copper connection to remote areas without laying down miles of cables in the jungle or prairies, and even then yes, they would need two of them per link for bi-directional communication, just like standard networking fibre.
***** the books would be sent and stored on HDD locally.. no need to send request through ISP at that point.
I agree, but the data of 'said books' would have to get onto the HDD's from the Internet in the first place at some point, and this would only be possible (with shown setup) through a broadcast packet transmission (which is how they were playing that video), of the same thing to everyone connected, and has to be initiated on the remote end, and the clients would have to have external knowledge of this upcoming transmission in order to download this book. If a packet gets lost on its way to you it could mean a corrupted, unrecoverable download. If the user misses the beginning of the transmission, tough luck, no download, the negatives go on and on. TCP, which is how most of the world transfers data requires two way communication, no way around it. This would be well suited to BROADCAST TV transmission, but again I think radio transmission is way cheaper than this, just tight on bandwidth.
Technically that can be done now via Satellite. In fact, my ISP specializes in providing Internet via satellite in remote parts of Africa! Good and valid point though ☺
***** My main point is that people are being critical of a technology that can revolutionize the way we look at internet/solarpower and many other things. They're being pessimists and disguising it as being realists.
I am so excited about this coming technology. I think it will transform how we use everything, including more respect for one of our most valuable resources: light.
well it was a big lie-fi in the end
Guy: "In the next 2-3 years"
Me: *laughs in 2019*
its 2020 now
It's cycle bro
The guy is obviously trying to sell this snake oil and failing.
@@EminemLovesGrapes
He demonstrated that it was not snake oil. I think he underestimated how difficult it is to get a product like this to market.
You want to just download? This is for people in poor countries like Uganda too download information
Incredible concept, I can't wait to see this idea progress and be utilised in our future society. Thank you world for the thinkers you create.
It's 2023 now. And Hardly anybody knows about it. Trust me, I'm from the future :)
A better way to put it would be "Thank you thinkers for the world you create" :)
@@fallenknight3352 absolutely, both comments work well. 😊
@@reality_official who knows maybe is being used. This can be used as optogenetics and we don know, just by applying different frequency to light could affect our bodies
Reading through the comments and disappointed with the negative points.. This may not be a complete concept yet, but it's a good start for a better future of the internet.
What do you expected? People, always fear what they cant see or taste. History repeats itself.. with one way or another.
This peace of tech is very, very innovating. I am interested to see how far this tech is gonna go.
Im using Avasva instructions to make it and I do it already :)
This is by no means a new idea. A TV remote controller used infrared light to communicate to the TV.
@basil fawlty - Billions of Codes shining through Sun Light every second. How do you think ALL living things, still living?
There is also optogenetics, literally an organic matter can be changed through light
Outstanding sir. You are a genius. Its the beginning of an new ers. ......
wow if this technology will be materialized in the near future it will solve slow internet connectivity and no one will be leaf behind in terms of fast paced data transmittal with the speed of light connectivity everyone can access the internet irregardless of their location or wherever they're may be in the world.thank you and Good luck Mr Haas and your team.
Ohhhh lifi for Internet. I thought it was about the Wireless energy source, which is again a great idea if anyone come up with that.
Rohit Eligeti a conspiracy
I guess google is already doing it
Rohit Eligeti tesla
I saw one, based on the Tesla coil, but it was encrypted and in use in electrically hostile environments. That was years ago and haven’t seen it advance further, the guy was inspired by his cellphone needing power but he couldn’t be bothered plugging it in.
But how will it work when other lights are shined on it? And how does each led know what device it is talking to?
+Minder Maniac
I'm assuming the same way our phone knows which Wifi router to connect to.
+Minder Maniac Probably some initialization protocol.
Appletank8 but our phones can talk back through wifi to the router, and the router hands out IP addresses to each individual device, but I don't see an easy way to have my phone talk to an "off-the-shelves" led
lifi technology is implemented or not??
It's not light effect it's decoding information from certain wave length
The idea 💡 is legit. I love ❤ it
This is amazing, this is so ahead of the future.
2023 and still... WiFi 🥱
Such a misleading title. Li-Fi was never intended to replace Wi-Fi.
That is only receiving, RX, when you want to connect something to the internet, you need also transmitting, TX.
5:41 The "fog simulation" doesn't fully cover the receiver part...
You could say that the bottom part receives the data...
Does fog cover the sun?
Really interesting, but wifi can go through walls. Could be really great for new technology and architecture.
+TheSpaceTiger
Satellites, man, satellites...
And remember that he said there would be laser stations.
+TheSpaceTiger A cable from the solar panel or a wifi converter into the house, what ever is more practical. In Africa, India and parts of south america this could be a solution to all their problems. Now lets see what the sceptic's say. It has to be questioned and tested properly. Thumbs up for his groundbreaking idea.
***** Indeed :)
+Darth Daddy Wi-fi goes thru walls ... also thru your head. I need it like a brain tumour.
Pee Pop There's already a tumour killer in development, if Bowie and Rickman had survived 5 or 6 years later they might have had much longer lives
What prevents a neighbor from pointing a flashlight or laser pointer on the solar cell and interfering with the data packets?
Dh nlghtnd 1 maybe it will switch to wifi.
fun fact. if you get a microwave to work while opening in your home your wifi will be messed up. Your wifi uses microwaves too. of course your wifi doesnt harm you because its like the difference between a flashlight and an led
Well even in the demonstration he had light from various places, which technically fluctuates ...
Seems they've overcome this somehow. Maybe packets get dropped in case of too much interfering, when it detects that something is wrong with the encoded data
DEO what prevents your neighbor today from stealing packets and giving packets today?
A shotgun
1. No upstream bandwidth
2. Interference from other light sources
3. Requires line-of-sigh
4. Short ranged
I'm afraid it just isn't going to work out.
Kindly make this possible to publish this project in INDIA as well as demonstrate it in most places and colleges of India
~Love from Indian Citizen
Just open source it d@mmît. 4yrs already and still nothing
What does daatmmît mean
@Archock Encanto lol
No, the world wouldn't be different if more software were open source. That's just a myth
Okay so we've always been able to transmit data using light and transmit energy using light. This technique allows you to do both at the same time. It's cool but it's not exactly "breakthrough". Solar panels aren't very efficient so there's only a narrow set of applications where this could be useful or practical. I don't see how this could replace wifi in a home, and I don't see how it could offer advancements toward the "internet of things" if all devices require a direct uninterrupted line of sight toward the source of a light beam. If I'm missing something I welcome anyone to help me out..
I suppose the idea is using the same hardware component to both harvest energy from sunlight and receive signals.
You'd still need new signal processing hardware and a transmitter, so I don't really see the point in terms of cost effectiveness, over using an independent radio communications module in addition to the solar cell.
The idea is to avoid massive energy consumption in future because most of the things will be using wifi. This idea is to conserve energy whereas using light source and making useful out of these solar panels. It is a very very life saving idea.
jade pomar This won't save any appreciable amount of energy compared to wifi. It probably uses even more energy. The point of it is not being low-power to begin with.
Don't go forgetting the law of conservation of energy, by the way.
+jade pomar Ye it sounds more interesting than it actually is (fiber-optics also uses light :D ). This will not save lives. It may conserve a bit of energy but the drawbacks are huge, there are much more efficient ways of saving energy. And in all honesty, energy is not that much of a problem, the sun alone could easily power the 10 earths if we had efficient technology. And just for the arguments sake, the biggest waste of energy/ food whatsoever is done by human behaviour, if we would live energy efficient/ nutrient efficient that would make a much much bigger difference than being able to reuse a tiny fraction of the energy that is used for communication.
What is the software to change of data
The solar panel is just powered with the led bulb and the video is streaming due to the power received and stops as blocked
If I send a text message or email and that is converted to light and then received and shown on the screen
Great episode!
6:57 it's 5 years nothing has come!
Maybe you are been programmed through optogenetics and you dont know
Forget 2015 ,this is 2018 we still use WI-FI 😂
2019 and still use WI-FI :D
of course we will still use it ;''= because if that technology become public so the wi fi technology will disappear , also i have had read that there is a scitest who discovered a technology used to transfer electricety without a wires so he was killed , why!! financeal side of course ////
@@dr-ihabtayem1896 u mean Tesla?
2021 still Wifi XD
this is 2023 we still use WI-FI 😂
I can see this being used for broadcasts inside a building.
Say you have some sort of Public address system inside a building. You would not need to run extra wires to have it connected to the entire system.
or
You have a mall with screens which only need to display stuff like ads, menus, emergency drills etc
Very impressive u took energy to another levell..
Yes, it can also be used as the opposite, someone can watch you as well. The question is how good for privacy is this?

Underrated af
It’s an idea that provokes innovators ,progress waits young man
I just got out of high school with an electronics shop...I could have build this their. I don't even think any realizes the implications on batteries and how much we use the Internet. If we(first world countries) cut down on our Internet usage we could charge just a few batteries and have them for night/emergencies. Cutting down our consumption, increasing efficiency, and giving EVERYONE access to this wonderful achievement of human success we call the Internet(our connection with an instant but distant world) are all healthy steps for humanity as a whole:) Let's keep up the good work
there*
This would only work to receive data via UDP i.e. stream video as there is no way to upload data, you can't even make requests or verify packets like you can with TCP = very limited usage.
If you want to send data with this technology you have to have a agreement with the Sun.
😂 😂 😂 😂 okay 👌
I figured in due time something would replace WiFi. It’s probably ready now, but energy hogs are lobbying to keep it suppressed.
More like 5g adopters

+Burgled He has lights, but he needs to add receivers in every room as well.
+666Tomato666 I guess that the system can transmit data using very dim light so it can "mimic" switching off the light but still transmitting data.
Mostafa Muhammad that's not what he showed....
I wonder what kind of image the sun would transmit to the laptop, im very curious now
noise probably
Maybe Advanced Alien civilizations have been trying to communicate with us via light for centuries and we will now be able to detect and decipher this communication? :-) (of maybe we could upgrade OUR communications into space using light instead of the current radio frequencies).
Remkye Henriquez static
We are already using this tech in simple household devices like TV's remote controller etc.
Remote controller uses an IR LED that transmits unique frequency infrared flashes(invisible with naked eyes) for every unique buttons which then can recieved by a reciever (transistor) and decoded and used as information
Also it's not practical to use it for continuous connection as required for internet connection due to need of LOS for transmission
A few disadvantages:
1. Too much light noise in the environment (other light sources operating at different frequencies).
2. Need a directional light source and receiver.
3. Can't normal use in dark (at night).
4. Can't normal use at open place, bcos sun.
Also. It's not new technology. It's just open optocouple, that using in rotating objects also with wireless power delivery (in lidars e.t.c.).

Fiber optics for communications. Can also be used in a laser config.
Thanks for the new technology sir
what's the point? it feels like energy wasted
*energy gained
You're making people put solar panels on everything
Solar panels aren't 100% efficient. You're still losing energy.
Trippy Tall i dont think you understood me, in order to send light signals you'd have to spend more energy than you gain, its basic principles in physics. So by just using a cable, it'll probably be cheaper by the time. Because these lights needs to be really strong, which makes them easy to be broken. solar power is always important to have anywhere in my opinion
Taha Ragheed He didn't say anything about the light having to be of a specific type or intensity... So dismissing what you're saying about the lights having a tendency to break(?)
So this is the point I want to make: There are lights everywhere, if they're already on anyway, it doesn't take more energy to transmit the data through the light that is already avaliable than by running a separate device for wifi. Right? On top of that, you have the solar panel on your laptop, harvesting extra power. It can harvest this power when you're not using it, too. Isn't this a net gain?
Trippy Tall I was just confused, it looks cool though
Dunno, it seems to me that before this could be succesful, we'll already surpass 50Mb/s standards by a mile. 10 years ago most people used ~1Mb/s, now 40Mb/s isn't such a big deal. Assuming 5 bilion devices in 5 years is rather generous, this technology might be rejected because of it's limitations and security problems that could occur because of the open nature of it.
What would an internet source look like anyway? Do they plan to make a new sun just for online connection?
***** Yeah, we pay per month as oppose to per tick (or whatever they call it).
I think the point of this technology is to allow developing countries to access the Internet rather than those people that already have fibre optic cables
+Mezurashii5
There are specters of light that we can't see.
Rohan Paul I'm not sure how much cheaper it's going to be if you consider the limitations of it, but I guess the presentation didn't show how the thing works in practice. The old-fashioned internet connection gets cheaper with time anyway though.
William Tael And it has little to no relevance to the topic, since the selling point is "off the shelf LED" utilization in data transfer. Do normal light cells work with those kinds of waves anyway?
If we use solar panel to descript data transfer from the sun what would that be ? As there is a speed of light and there is a travel time to it and and that becomes a frequency of data transferred in form of light
Although, its only one way communication, we already have other methods of communication for the internet like 4G and satellite links. I can imagine that the smaller bandwidth link will be used for two way and the LiFi being used to transfer the actual video or file itself.
Now what is the actual real world application?
Replaces Wi-Fi while harvesting energy... Duh
Kian Heus I mean the specifics. Range, usage, power consumption, efficiency. Can it handle multiple simultaneous transmissions?
Real world application is "We have this internet broadcasting light here, and it provides internet access to this whole village via lifi, while not causing light pollution and takes almost no energy to run." and even more details.
Yes, you can transmit data over light, but how will you apply it.
The internet is usually a 2 way connection. Especially TCP to sync and acknowledge you received the packet. UDP is like a one way transfer, but that would be like broadcasting a TV channel to everyone. No stop, no rewind. if you lose a packet, it is skipped over. What about night time? It sounds useful for sending radio and TV broadcasts, but not the internet unless each person can beam a laser back and have a separate dedicated connection. Might as well use infrared, microwaves, lasers, or just 4G. I don't get it.
***** Did you? Where did he ever mention simultaneous data streams, light pollution, or range?
+Anime Summit Phone to Phone short distance high speed transfer? Just attach a solar panel to any phone and use camera flash to signal.
Lifi = Fancier name for what your remote control uses, and what many devices used to communicate like 20-30 years ago, and did not really work that great back t hen since you have so many interferences that emits IR light.... (and that made it really slow in real life... but I guess in theory its always superfast. speed of light!) I dont see the use of this since Wifi is supieriour in every way.
It's very cool tech - but the reliance on direct line of sight between two points seems like a major hurdle to this ever becoming a dominant general-use technology.
Also - how do you deal with 2-way communication in practical terms?
The problem of this technology is the modulation index. I can imagine, if you operate your solar cell outdoor in bright sunlight with more than 1 kW/m² it could be a problem to transmit data with a 1 mW laser pointer directed to the solar cell.

This technology can be used to interconnect towers instead of fiber optic cables. The same further can be used to communicate within a campus where the wife range is not enough to cover the area by making LAN switches (wireless).
Systems Academy Can you help me? I would like to know what tools and equipment I need to design this circuit. I would like to know the names of the pieces and their numbers.
Neat trick. I don't see many practical uses though.
Consider this... light is a representation of electromagnetic waves. Yep, WiFi, cellular, sattelite, etc all also communicate via electromagnetic waves just at different frequencies. Once you start trying to engineer a wireless modem and dealing with problems like multiplexing, channel noise, etc. you'd wind up with just another wireless communication technology with it's own pros/cons and dedicated infrastructure.
I do like the utility of a dual purpose energy and data delivery technology. Maybe some day when every house has solar you could transmit over the air television like this. But this is no replacement for WiFi.
An Arab poetry says : Al ilmu nurun = knowledge is light..what a coincidence
Good talk, horrendous title. This has nothing to do with WiFi...
How to request the data
That means how two way communication does work
What's new about this isn't the use of light to transfer information, it's making solar cell panels dual-purpose. The energy collected from the signal light source will be only a fraction of the energy needed to power the source, so it isn't really reducing the energy consumption. However, production and shipping consumes a lot of energy so multi-purpose items may well lead to significant reductions in energy consumption. Ambient light will also be utilized, of course, but the higher the energy of the ambient light the higher the energy of the light signal must be, which limits the net effect. It would make sense to use it for data transfer whenever the ambient light is low (like at night or when overcast).
As for it being "only one way and therefor useless", that's like saying talking is useless because you can't hear with your mouth. Once data can be transfered, using a transmitter and a receiver, it's trivial to set up full duplex communication - you just set up a transmitter and a receiver on both ends.
This technology is quite easy to interrupt, though, or stage "Man in the middle" attacks. As you may have noticed, the "fog" didn't stop the video transmission, but made it choppy as not enough data could be received. Since it's not just the amount of light reaching the solar panel, but the difference in strength between the signal and the ambient light, it can also be interrupted/reduced by adding (ambient) light. Just shining a flash light on the solar panel might be enough to severely disrupt the service. Or, you could use another transmitter with a significantly higher energy output to "replace" the data being received.
This technology may have its uses, and it's good that people are thinking outside the box, but with so many other things, it may take a while until it becomes "consumer ready" - if it ever does. Who knows, perhaps it'll serve as an inspiration to something else that's more practical. Either way, it's a step in the right direction, and a needed reminder that information sharing on a global scale does come with a high energy cost. I wonder how much energy we'd save if people didn't comment on YT videos like I've just done..
*HEY 2015, ITS 2019 AND HOWS THAT Li-Fi WORKING OUT FOR YOU*
You want to just download? This is for people in poor countries like Uganda too download information
2019 no change .....¿
I feel like there are many devices hooked up to one wifi router but only one device can receive data from this, also if someone wanted to see what data is being downloaded (also might i reiterate no upload capable) this would be relatively easy without the need for a password
That's a great inspiration to a newly coming future

@@brandonhernandez7252 - Ask why...... Idiot !!! 😂😂😂😂😂😂😂😂😂😂
My main question is how distortion of the transmitted light will affect received data, and also how practical this would be in terms of light pollution. Not only this, but how effective it is with conflicting light sources, especially bright daylight
Very likely ML algorithms could effectively adjust for distortions etc
Bright daylight can easily be eliminated as they will just be reflected as a constant dc noise in the receiver
This has A LOT of drawbacks for communications between structures. As said before there must be a line of sight, also the weather has to be nice, not cloudy or foggy. I think that li-fi could replace wi-fi if we talk about intra structure communications, such as buildings public wi-fi.
I wasted my WiFi watching this sci-fi Lifi so bye-bye

😄 yeah
I'd rather use this than radio waves. I mean, if houses can be re-engineered so that the lightbulbs in each room transmit data as well as energy, you'll never run out of battery or data. It's like having a router in every room. Then, there could be omnidirectional solar panel spheres installed next to the lightbulbs so it can receive information from your device (from any angle) as your device flickers the data back via some small LED light.
And then as the technology progresses, you could turn off the light at night, but still get data if it can be transferred via infrared light, which does not obstruct even in the dark.
The idea has potential.
Love the idea, and I'm sure it could be faster. However... outside of redecorating, sometimes massively, light doesn't penetrate solid objects. Your cell would have to be in a good enough spot, then you'd still have to be wired to all the computers/etc. in the house. Also, a light fog might be fine, but if you're in Britain or Seattle, we're not talking about light fog. This also accounts for normal and heavy clouds if you're talking satellites. The rain might also be an issue as each droplet can disperse light. If we're talking ones and zeros that's a ton of data loss.
Keep in mind I know very little about solar energy an it's possibilities in data transfer. These are just possible problems according to my limited knowledge in the field... What if it's already very bright out? Would the LED even register?
How about laser ir or other spectrums ?
this video 2015?now 2018.where is li-fi in 2018?how to forget wi-fi?you want people die?
15mb/s is faster than most broadband connections? Horseshit.
+Baustin McManus *50
50*
Baustin McManus 50 mbps not 15
Very well sir a revolutionary effort loved
How can someone dislike the video????!!!! Awesome invention.
Lol this never happened
50 megabits its nothing compare to google fiber 1000 megabits
+Potatoes gonna potate he is just advertising the product which i consider nonsense, people just wouldnt change wifi
+Cristobal Elorza When I first hopped on the internet back in 95 I only had a 56k modem it went to 128k etc.. over the years... But I'm sure 50mbps would be a huge change to someone with 0mbps right now lol....
+Cristobal Elorza The record for Li-Fi is 224 gigabits per second.
In another vidoe he talks of 50-200 GB NOT mg
This energy sustaining technology is awesome
Thanks for the MARATHI Captions
What was demonstrated, was Light Radio, not network. While cool, WiFi replacement it is not, but probably could be used as extra downstream bandwidth for existing networks.
1. How do you request data/upload?
2. If I want to go to the internet or receive internet I need to have my lights on? So I can't browse internet in a dark room without light? or would it be Infra Red light?
3.Obstructions ruining the lights signals

I would think that when this technology mature, they would have repeater that will send the Li-Fi signal around corners and other obstructions to reach the computers.
They already have repeaters for Wi-Fi to reach area where the Wi-Fi signal is weak.
They just have not think of it right now in the beginning. But when the Li-Fi technology mature, they will have other technologies to do the same for Li-Fi.
I think it is code work which makes vedio move depending on light strength ,not as taking data
My last speeding ticket happened because I thought the limit was 65. The cop said it was 55 mph, which, surprise surprise, it was. Why didn't the speed limit sign tell my car what the current speed trap required and display it on the nice Mazda HUD? Or transmit current road conditions? Wouldn't take much innovation with this technology to make it happen and save me from Louisiana speed traps. Now that would really be a smart car.
