Li-Fi Explained

[@prajithar6174]

All information about lifi in one video. Good 🤟🔥🔥🔥🔥🔥🔥🔥🔥

[@vinuthnasrija14]

Very helpful. Very clean explanations. Thankyou

[@nsangouchouaibou7372]

Very good video on Li-Fi. Li-Fi technology has another drawback : We are using light switched ON to communicate, thus meaning electrical consumption.

[@abubakkersiddiq5925]

But that light is made from LED so advantage of LED less Power consumption... So not big problem

[@ojasviarora6816]

Power consumtions is quite less than wifi dear

[@林峰-l9e]

The LED lights are already in use for lighting, so actually the tech means less energy consumption rathre than more. Because the flashing would cut down the consumption.

[@ashishkumarparida7495]

Thanks ...

[@surajbiswas8642]

Nice.. But i have question that when a lifi dongle kept under more than one lifi transmitter led light then there may inter meshing of data those will transmitted by the dongle to the led light or that may be fluctuation or connectivity. Please reply...

[@ALLABOUTELECTRONICS]

Like in the case of Wi-Fi, as some standards are defined, (IEEE 802.11) for Li-Fi communication also some standards are defined. (e.g IEEE visible light communication standard). And if you see these standards, each device has its own unique physical address. So, even if there are more than one LEDs in the room, dongle exactly knows to which LED bulb it is communicating by specifying the address before transmitting. So, even if second LED bulb receives that data, it will not participate in that communication, as its address is different. And same is true if multiple dongles exist in the room. I hope it will help you.

It would be nice if it had subtitles so it could be understood!

[@ALLABOUTELECTRONICS]

Subtitles are already there. You can use it.

[@himanshubhatt5460]

Nice explanation

[@soumyajeetmitra6958]

informative easy to understand video. just to give an ex, though, in 2023, BSNL has 100 GBps of speed being offered and minimum of 3GBps

[@maheshgoel6850]

Superb video

[@aravadurgasuvitha2163]

this viedo is so clarity thank you

[@nishanthreddy9486]

sir we have separate IP address for routers to provide wi-fi facility so that servers can provide services to some router .what can be replaced in the place of routers which server can recognize and provide services to that specification?

[@its_me_animegamer32]

Sir tell me please that what is the principle of this project

[@arunkumars3007]

amazingly explained.. cheers

[@NinjaSushi2]

Thank you buddy.

[@nsuma1237]

Very nice and well explained vedio😃 But I want What are the disadvantages of li-fi Can u please let me know

[@rutujasuryavanshii]

What is the purpose of using RGB LED's ?? ...and the video is helpful ✌

[@ALLABOUTELECTRONICS]

Using RGB LEDs in the single source we can increase the bandwidth (and hence data rate ) of the source. Using different colors of LEDs, we can transmit data on each color (wavelength) LED. So, we can achieve 3X data rate using this technique. One more thing, when this technique is used then at the receiver side also you require RGB color filter which can distinguish three colors.

[@utkarshsrivastav6693]

RGB increases bandwidth without interference and sometimes it may be used as contingency bandwidth source(very special cases).e.g. there is red light already present in background so receiver will be deceived so it will use other two colour LED.

[@abhinavbalcha9666]

The video was very helpful. Thanks!!

[@poojashah6183]

Perfect 👌👍

[@komalsrinivasan9483]

I am very much impressed with content so I want save the ppt

[@dipeshsapkota844]

How do we receive data on our smart phone ?

[@ALLABOUTELECTRONICS]

The phones should have a photosensitive receiver (Like photodiode) to receive those signals. And I think it can be fitted on the front side of the phone, much like an ambient light sensor. Or it may attached separately to the phone.

[@peterstark2716]

Smartphone ke front me senser dia jayega i think.....

[@abusalim6248]

You can do it with external photodiod. Add it by yourself

[@K.shitiz]

finally a good exp. video

[@renithomas6559]

Excellent vedio

[@arjmishra]

Very nicely explained

[@VinayKumar-pp9lm]

Will u plz explain web1, web2,web3 technologies

[@geoffreykeane1364]

Can I buy it now? If yes where and how much - I live on a farm in the Philippines and getting wifi is hard and very expensive

[@ALLABOUTELECTRONICS]

Please check this link, It might help you. You can contact them for further information. purelifi.com/lifi-products/

[@geoffreykeane1364]

I have send 3 emails to Purelifi to buy their Dongle but to date have not received a reply. Makes me think it does not exist

[@ALLABOUTELECTRONICS]

Try to call them if possible. I think in telephonic conversation you will at least get some reply.

[@haiderkhan3892]

Good

[@shobhittyagi6006]

Sir you should write a book about all concepts

[@only4u764]

Thanku

[@erikasbed1933]

Can a few users use the same Li-Fi source for different purposes?

[@ALLABOUTELECTRONICS]

Yes, that is absolutely possible. It is very similar to the Wi-Fi, except the fact that it uses visible light source for data transmission.

[@peterxyz3541]

How do I get some of this tech?

[@ALLABOUTELECTRONICS]

As I mentioned in the video, there are some companies like PureLiFi which provides commercial products.

[@jarithap.b1699]

Thanks bro 🤓🤓

[@sumanthreddy3953]

Good job bro

[@daredevil2032]

How can we do under water communication ?as there is no light in the water..

[@ALLABOUTELECTRONICS]

For underwater, SONAR is used.

[@vigneshwaranjk9586]

Nice

[@wizzo1351]

Thanks bro

[@vivekkumaryadav9170]

superb

[@indusmily497]

Tq bro Good explanation

[@td3993]

Aside from offering a low interference data transmission method, using the acronym "li-fi" for optical data transmission is rather dumb. It's stealing from hi-fi, which is the abbreviation for "high fidelity." Light fidelity would best refer to the color accuracy and spectral completeness of an illumination soure, not an optical data transmission system. I'm also really not sure why wireless data transmission is referred to as Wi-Fi other than because it sounds trendy and cool.

[@prathameshsatyarthi5552]

Which modulation is used in lifi

[@ALLABOUTELECTRONICS]

OFDM (Orthogonal Frequency Division Multiplexing)

[@sonalisingh2827]

Sir can i get an explanation in written form

[@vigneshwarreddy2984]

Why the lifi technology doesn't used in the mobile phone

[@tammy_lynn1628]

For those who can’t understand his speech.. click the three dots on the top right- turn captions on English.

[@gurukannan3452]

wheather it has any disadvantage ?

[@ALLABOUTELECTRONICS]

The only disadvantage is its range. As it uses visible light source and light can not penetrate walls, so the range is limited to the room only. Second, the high speeds which are achieved in the labs are under certain conditions, like light source and receiver should be in the line of sight. So, if they are not in the line of sight then speed might reduce. Let's say you are receiving scattered light, but in that case, too it will provide better speed than Wi-Fi.

[@esdeee303]

Lifi can only transmit data, not receive. That's a major disadvantage.

[@alchemicalvisionstudios3969]

Maybe we incorporate the sun for this

[@timothydegandi]

RFID is a radio frequency protector if you put your phone in that kind of bag your phone don't work

[@balajiezhumalai7429]

useful

[@vijvalpatidar7946]

How could I get that theme that was in video...

[@Diogenesthedog0]

I have some concern with Li-fi technology. One can use Li-fi as an alternative to Wifi Technology but they can't replace Long coverage Radio Waves based Towers. Since, Li-fi uses Visible Light Frequency and we all are surrounded by Visible Light sources all around. So I think the receiver end may take some wrong Inputs also Signal Interception will be much easier and to me it's less secured. Imagine a Scenario, A pulsating light is being sent from the source. Even if the light is pulsating too much but some cheap technology one can certainly see the Pulsating light, Since we have CMOS chips which can detect Visible light so if Slowed down enough can be traced. What you people think?? I have many other points as well.

[@asifalamgir5135]

oTHER POINTS ??

[@MoneyMatter290]

can we establish a router using Li-fi technology .? if no , then how we utilize in our daily work?

[@amankumarpurohit3008]

Thnks

[@-ANDY.]

How would that work with AC power which is already flickering?

[@ALLABOUTELECTRONICS]

AC power is first converted into DC and then then it is modulated at very high frequency according to digital bit stream.

[@dibyasekhar8094]

What it win 1st prize in science exhibition??

[@sayyedfarhan9351]

Brother I want to write the research paper on these topic plz help me on it!!

[@yinyang9109]

Hope someone invent a micro nano mobile li-fi hot spot device anyone or anyplace can share internet traffics to each other and everywhere is awesome.

[@amankumarpurohit3008]

How can we make it at home

[@ALLABOUTELECTRONICS]

well, the very simple model can be made at home by using the LED and the photodiode. As an experiment, you can send your own voice or music ar one end and by using photodiode you can receive that signal and apply that signal to the speaker.

[@shimelisgab7175]

Due have any code related to this work sir?

[@dulanjankarunarathna]

how it communicate its only have only transmitter ??

[@spg00312]

Well when it comes to #Security... muze nahi lagta ki esi koi bhi Technology hai jo puri taraha Secured hai... Coz haar ek Technology batati hai ki wo secured hai... but koi na koi Vulnerability usme humko mil hi jati hai...

Congratulations again...

[@ashrafunnaharpriti3457]

thank you🤩

[@WLHS]

@@ashrafunnaharpriti3457 your welcome. I had noticed you made a comment about your science fair project on a different video, that made me realise you are very studious. (I think many people are afraid of 5G technology because they don’t understand.). Personally I believe Ali-Fi could change many planetary problems caused by manufacturing & using “wire” of various metals, synthetics and other compounds.

[@ashrafunnaharpriti3457]

oww!!thank you🥰

[@025gctyuvaraj3]

how to used lifi tech in this application

[@Afrocanuk]

Fast talking with a strong ethnic accent...

[@jarithap.b1699]

How much is for pure Li-Fi

[@ALLABOUTELECTRONICS]

You can directly contact the company for pricing. Now, they are providing an integrated solution.

[@DeepakJindal07]

40 to 50 Mega bytes or Mega bits?

[@ALLABOUTELECTRONICS]

its in bits per second. 40 to 50 Mega bits per second.
