 What is Li-Fi Technology

Hello , welcome to our blog  JMD TECH SPOT  in this blog, we will find out about the Li-Fi innovation. Which is the condensing of term Light Fidelity.


Thus, in straightforward terms, we can say that this Li-Fi Technology is only light based wi-fi innovation.


What's more, as we probably am aware, this Wi-Fi is completely organized, bi-directional remote correspondence innovation.


Where information is being transmitted utilizing the radio waves. While on account of  Li-Fi Technology, the information is transmitted as obvious light utilizing the LED light source.


Along these lines, this house hold LED bulbs and LED lights which are utilized as a light 
source can likewise be utilized to transmit the information. 


In this way, as a matter of first importance, how about we see how this Li-Fi innovation functions. 


Along these lines, on the off chance that you see any LED light source, in the event that you give the steady present to this LED bulb, it gives the consistent brightening or steady splendor.


In this way, as we change the present that is coursing through the LED bulb, the light or brilliance of this bulb will change.


Along these lines, this princi[ple is utilized for transmitting the information remotely utilizing this Li-Fi innovation. 


Along these lines, in the event that no present or least current is moving through this LED bulb, at that point, the brilliance of this LED source will be least. 


Also, that will be treated as computerized 0. Thus, advanced 0 will be transmitted at the collector side. 


Additionally, when the light is ON, or we can say that on the off chance that the most extreme measure of current is coursing through this LED bulb, at that point the brightening or splendor of the LED bulb will be greatest. 




Further more, that will be treated as computerized 1. Along these lines, at whatever point the LED is ON, so advanced 1 will be transmitted at the recipient side.


Along these lines, thusly, by flashing the LED light source quickly we can transmit the information as 1's and 0's to the beneficiary. 


What's more, on the off chance that this flashing is occurring at million times each second, at that point we can not see this glinting by our unaided eyes. 


Furthermore, we can treat this LED bulb source as typical standard bulb source. In this way, presently how about we see the schematic of Li-Fi transmitter and recipient framework.


Along these lines, as should be obvious, the information which is originating from the web server or the web first it will go to the MODEM, 


Which gives the essential tweak to the approaching information stream. At that point this tweaked information is taken care of to the LED driver,


Which changes the driving flow for this LED bulb as per the approaching spilling information.

At the recipient end, in the event that you see, the optically gotten information is first changed over into the electrical sign utilizing the photograph beneficiary or photograph diode.


What's more, after the sign molding, this information is being taken care of to the PC or PC.


Along these lines, to get this approaching information, at the beneficiary side we require the Li-Fi dongle, which comprises of photograph collector just as IR transmitter.


Presently this infrared transmitter can be utilized to transmit the uplink information back to the LED source. 


Presently, one such organization which gives the total Li-Fi arrangement is Pure LiFi. Which for the most part makes these Li-Fi dongles. 


Along these lines, presently as we probably am aware, how this  Li-Fi Technology works, presently how about we see the benefits of this Li-Fi Technology 


Over the different remote correspondence advancements. In this way, these are the a portion of the upsides of the  Li-Fi Technology over the different remote correspondence advances. 


In this way, first how about we talk about the speed. Along these lines, so far the specialists have accomplished the accelerate to the 10 Gbps in the lab scale model models. 



Also, this speed can additionally be improved by utilizing the variety of LED source or by utilizing the different shades of LEDs like RGB LEDs.


Where each LED source can transmit the information up to the 10 Gbps. In this way, utilizing such advances.


The analysts have accomplished the greatest accelerate to the 100 Gbps. Along these lines, presently how about we contrast its speed and different remote correspondence innovations. 


Along these lines, on the off chance that we contrast it and 4G/LTE or especially the LET propelled, the most extreme reachable speed under this LTE progressed is 1 Gbps for the fixed client and 100 Mbps for the portable client. 


Be that as it may, every one of these paces are the hypothetically attainable most extreme speed. 


However, genuine speed might be a lot lesser contrasted with this hypothetically feasible most extreme speed. 


In this way, on the off chance that you see the nations which give the quickest web on the planet, the normal 4G/LTE speed in such nations is in the scope of 40-50 Mbps,


Which is a lot lesser contrasted with the speed which is given by the Li-Fi. In this way, presently we should contrast the speed of Li-Fi and Wi-Fi. 

How Li-Fi Works?

Presently, in the event of Wi-Fi, on the off chance that you see the standard IEEE 802.11.ac, the most extreme speed which can be bolstered by this standard is 1.3 Gbps. 


Furthermore, that is in the 5 GHz band, which is just about multiple times lesser contrasted with the speed which is upheld by the Li-Fi.

What's more, on the off chance that you see the another Wi-Fi standard,


Which isn't economically accessible yet, that is IEEE 802.11.ad, the greatest speed which can be upheld by this standard is 7 Gbps. 


And all the paces which are referenced here are the hypothetically reachable most extreme rates. Be that as it may, the real speeds might be very lesser contrasted with the hypothetically attainable most extreme rates.


What's more, still, on the off chance that we consider the greatest speed which is bolstered by this Wi-Fi innovation, 


The Li-Fi innovation is as yet multiple times quicker contrasted with this Wi-Fi innovation. 


All things considered, at this moment the speed which is given by the Wi-Fi innovation is adequate for our everyday life. 


In any case, as we are moving in the time of Internet of Things, where every gadget can speak with one another, soon you will find that the speed which is given by the Wi-Fi innovation is lacking. 


What's more, you will require the crazy speed like 100 Gbps, which starting at now resembles a fantasy. 


Thus, next, in the event that you see the electromagnetic range, the transfer speed of the radio wave is up to 300 GHz. 


Be that as it may, in the event that you see the transfer speed of this noticeable range alone, the transmission capacity of this obvious range is around 300 THz.


Which is very nearly multiple times more contrasted with the transmission capacity of the radio waves. 


Along these lines, you can accomplish the higher speed as well as you won't locate any sort of electromagnetic radio obstruction. 


Along these lines, presently on account of Li-Fi, as we are utilizing the noticeable light source, the obvious light source can not cross the dividers, not at all like the instance of Wi-Fi, 


Where the radio waves can transmit over the dividers. Thus, along these lines, this Li-Fi innovation gives the one more layer of security. 


Along these lines, these are the benefits of this Li-Fi innovation over the different remote correspondence advancements. 


In this way, presently we should see the various utilizations of this Li-Fi innovation. 

Along these lines, this Li-Fi innovation can be utilized in the medical clinics. As this Li-Fi innovation is giving rapid web correspondence, 


So the ongoing wellbeing checking of the patient will be conceivable. In this way, aside from that this Li-Fi innovation can be utilized for the submerged correspondence.


Additionally, utilizing this innovation, the vehicles can speak with one another utilizing the front and the back lights. Furthermore, utilizing this innovation, we can forestall the mishaps.


Likewise, this Li-Fi innovation can be utilized in the planes to give the web to the travelers.


What's more, not just that on the off chance that this innovation is fitted into our road lights, at that point even our road lights can give us rapid web. 


Thus, these are the a portion of the applications where this Li-Fi Technology can be utilized. 


Yet at the same time, on the off chance that you see, this Li-Fi Technology is the advanced innovation. 


That implies, the economically there are no items which are accessible which gives the crazy accelerate to the 10 Gbps or 100 Gbps. 


Thus, in the up and coming years, we may see the technologies or gadgets which bolster this Li-Fi innovation. 


In this way, at the present time, as we are seeing the Free Wi-fi Zone in the cafeteria, in future we may see Free Li-Fi zone in the cafeteria. 


In this way, presently greater inquiry is on the off chance that Li-Fi is the eventual fate of web, at that point shouldn't something be said about the previously existing remote advances. 


In this way, the appropriate response is that in future additionally all the current innovations will remain. What's more, rather this Li-Fi innovation will supplement all the current advancements. 


Since this Li-Fi is short range correspondence. Thus, utilizing this innovation we can not cover the whole region utilizing the light. 


In this way, terribly we can say, when you require huge inclusion, we will in any case lean toward Wi-Fi and 4G/LTE yet in short inclusion, 


As on account of our room or lodging or even workplaces, we can in any case favor this Li-Fi Technology. Along these lines, I trust in this blog, you comprehended about this Li-Fi Technology
