Well... I wouldn't say it's a lie, it just seems really inconvenient. Wi-Fi IS good exactly because it goes through walls and in all directions. I can't really imagine any circumstance where Li-Fi is usable, except for lab conditions. For a stationary pc - if you can run a wire for Li-Fi to a nearest lamp, you can probably just run wired connection to that pc anyway. For a laptop or phone - any obstruction, or angle change has non-illusory chance to mess up connection. So, it's not "a lie", it's just... Why?

i have that same question. and then there is the line of sight issue. its just like sending internet via lasers. one potential option i have just thought of is to have multiple sensors around a room, and the mobile device will be able to emit light signal in any orientation, because in nearly every plane, a sensor would be able to capture the signal. and to further that, all street lamps could be converted to send/receive signals. so it wouldn't be a long distance interface, but more like a localized net, meant for high traffic zones. but, it is cheap. u just need a modified modem and led lamps for the transmission, and then receiver sensors for the reception. then connect to the net. the main advantage would be the speed, and that would only really be useful if 20 people want to live stream 4k at the same time in the same place.

biggest problem with this - communication must be bidirectional, that means light bulbs will have to have ability not only to emit light, but also to receive; handset devices will have to have to have not only an "eye" to receive the light, but also a bulb on itself (not necessarily visible light bulb, maybe IR or UV) and that bulb must be quite powerful in order for it's beams to bounce off walls and floors.

Speed doesn't only depend on your Wifi, Gr-Fi or any other Lifi thing, It depends on your TCP/IP link speed too. Right now, Wifi with 802.11ac feature we can get max 1Gbps, and In future (means 1-2 years only) It will rise to more speed (ideally 10Gbps) and So, WiFi is very much mature and progressive thing. Nobody easily can replace it.

Some of the reviews were hard to understand (especially if you're not a tech person), but what I gathered was that people's bulbs were going out, this required some kind of subscription for "additional features" and they're far more expensive than one would expect- considering the aim is to change the world.

@shinjisan2015 6 жыл бұрын
All electromagnetic waves (radio, light etc) move at the same speed in air... the speed of light. The difference is the frequency of the wave, that is how many peaks and troughs in a second. Each peak and trough can be used to signal on/off or digital states depending on the translators. On/off is binary, the basis of electronic communication, and a single "bit". So, the higher the frequency, the more bits per second can be transmitted. The issue isn't the transfer medium, it's the translators on either end. Mainstream WiFi uses 2.4GHz and 5GHz signals... which have the theoretical maximum throughput of 2.4 Gigabits per second and 5 Gigabits per second. Yes, LiFi can reach HUNDREDS of Gigabits per second in testing, but the translators on either end are still the bottleneck. Think of it as your water supply to your house. The very large mains water pipeline running through the neighbourhood does gigalitres of water per hour. But, your tap can only do tens of litres per hour.

Ya, would work along wifi for specialized purposes. Everything we used has to pass through walls so that we can have one send point in our house. A company with several computers might have a system like this installed with something as lasers to communicate to all the devices, but light pollution might easily become a problem. Controlled environment, as in an office building, but not downtown wifi. Also limited to the hard wires and the converter. But it is faster.

He puts his hand between the receiver and the light source and the signal is blocked. That's not a success. Now, were he to put his hand between them and have the receiver still be able to detect the pulses from ambient light I may consider that a success. Basically, you have to have the optics of the receiver in direct LOS to the source for this to work. That's not a step up from Wi-Fi.

EDIT: Thinking about it again, I don't think a phone will be able to upload using li-fi, and it's the data you send (searches, passwords, naked selfies, bank details etc.) that needs to be protected more than downloads. So I just can't see how this can be more secure than wi-fi.

@MikeTrieu 8 жыл бұрын
Arioch IV Who said anything about another high-speed network? All you need to exchange is timing information on a periodic basis for TDMA signaling. You could achieve that with simple IEEE 802.15.4 (a.k.a. IoT) radios. As for transmitting from receiving devices, especially on mobile handsets, I'd imagine one could modulate the LED backlight on LCD-based displays or directly on AMOLED-based ones. If that turns out to be insufficient (not enough intensity), OEMs could integrate a dedicated Li-Fi LED array somewhere near the top of the device like some phones already do for IR blasters. It also doesn't have to be visible light, just invisible IR so as not to be totally annoying to nearby users.

But you just have to make sure you don't block the signal, which shouldn't be a problem if your transmitter is on the ceiling. Either way, if you block the li-fi signal , then I'm sure that a shadow won't mean total signal loss. Light bounces off walls and objects into where the shadow is. That's why a shadow isn't completely black. There is still some light getting to the shadow, just at a lower intensity. The signal should still get there then but your internet speed may just decrease a bit.

From my experience on video streaming;when data is exchanged via a video format (depending on the size of the video and speed of the data connection) some part of the video is loaded already,usually more than 2 minutes. What does this mean? So,covering a light bulb and stopping the sensor from calculating the flicking binary lights tingy shouldn't stop the video from playing. To me,that was just a remote control programmed with a simple if statement. If (flicking light is detected) {play video;} else {pause;}. I am not saying LIFI doesn't exist. All i'm pointing out is,that video presentation is not convincing enough to deserve the hand clap it got.
