Global monopoly of technology

Luo Sheng demonstrated for about three minutes. The staff took the laptop from him and left the stage. He once again stood alone on the stage.

There was a crash.

The audience resounded with thunderous applause. Most of the reporters present today are domestic media, and most of the media people have a high sense of family and country. In this situation, they did not hesitate to give their own applause.

He also mastered a technological commanding height.

The Côte d’Azur has mastered a brand-new black technology. The more advanced the technology, the more advanced it is. The Côte d’Azur has once again proven itself as a leader in cutting-edge technology.

Some foreign media people clapped feebly, especially the European media people now don’t know how to describe the complicated mood at the moment. Luo Sheng made it clear that this technology was invented by Europeans, and I don’t know if he is admiring or mocking him. I don't know whether to be happy or depressed.

No, for Europeans, it's like stabs in the chest, deeply rooted in people's hearts.

LiFi technology is now on the Côte d’Azur. Even if Hyland Haas is dug away, LiFi technology cannot be taken away, because PureLiFi is already on the Côte d’Azur.

What's more, Hyland Haas might not appreciate it. If it weren't for the short-sightedness of European capital at the time, how could it be possible to find such a huge bargain for the Côte d'Azur?

It is worth mentioning that now the outside world’s attention is focused on the Côte d’Azur. Almost no one pays attention to another technology giant in China. Almost in the same year, it paid a professor named Eldor from Turkey. Under his command, his technical theories have played a vital role in the development of 5G technology, and everyone has not paid attention to this unusually low-key but equally powerful technology company.

"What is the difference between LiFi and WiFi? In addition to providing the advantage of lighting, what other role does it have?"

Luo Sheng looked back at the data on the big screen, and then added:

"There are five major advantages. First of all, the emergence of LiFi can solve the problem of network congestion. The development of WiFi is limited by radio frequency technology. Computers, laptops, printers, smart TVs, smart phones, tablets and other electrical products are competing for bandwidth with each other. With smart home equipment, refrigerators, cameras, and even watches, and more devices that can use WiFi, interviews will continue. Coupled with the data diversion of mobile networks, traffic jams will become more serious and the quality of information transmission will inevitably be affected. LiFi uses light waves. , Its bandwidth is more than 10,000 times the RF bandwidth, and it does not conflict with WiFi."

"The second is the protection of data. Radio waves can penetrate walls and ceilings, but light has no such ability. This can reflect the difference between LiFi and WiFi in terms of data protection. Hackers or intruders outside the building can penetrate The indoor computer transmitted by WiFi, but the information transmitted through LiFi can only be accessed within the lighting range such as LED."

"The third is application safety. WiFi will produce electromagnetic interference, which affects aircraft equipment and medical instruments. The drilling and mining of power plants and oil and gas is potentially dangerous. As mentioned earlier, LiFi is safe and will not bring Electromagnetic interference."

"The fourth is speed. The 802.11ag wireless protocol standard WiFi can provide a data communication rate of 54Mbps, and there are also technologies that can increase the speed to 1Gbps. However, PureLiFi's laboratory data shows that Professor Hyland Haas, the father of LiFi The team has achieved a speed of 3Gbps using a monochromatic light source, and using full-color, that is, red, blue and green LED lights can be increased to 9Gbps. I am looking forward to the day when the laboratory is commercialized."

"Finally is throughput. LiFi's throughput far exceeds WiFi. Now the 2.4GHz and 5GHz frequency bands have become saturated with existing devices such as wireless phones, Bluetooth, and WiFi, not to mention augmented reality, virtual reality, and autonomous driving. There are new things like cars and billions of IoT devices."

LiFi technology was originally a niche technology in the industry. People can say that WiFi is a household name, but few people know it about LiFi, and only those in the industry know it.

Now Luo Sheng has come out to promote this technology in person, and it has suddenly become a hot spot in the industry, and the attention he has received has skyrocketed. Behind the scenes, Hyland Haas is also happy to see the current situation.

The outside world basically made a simple summary from Luo Sheng’s introduction: LiFi is a visible light wireless communication technology equivalent to WiFi, namely VLC, which can use light-emitting diodes, that is, the light waves of LED bulbs to transmit data, and can provide lighting services and wireless at the same time. It is connected to the Internet without electromagnetic interference, which can better protect data security and help alleviate the congestion caused by the surge in network traffic today.

From these perspectives, LiFi's development prospects indeed have great imagination.

Coupled with the support of the Blue Coast and the entire Greater China market, shaking the dominance of WiFi is not a castle in the air. No wonder people in the WiFi Alliance feel that they are watching a horror story.

Are there few things that Luo Sheng has subverted the industry through technological innovation?

On the stage, Luo Sheng said with a kind smile: "WiFi has had a huge impact on the application of mobile computing. People can access the Internet from anywhere, and even coffee shops can become offices on independent workdays, but they are not very safe. Reliability, it can be seen that WiFi also has its shortcomings, so a new standard was born: LiFi. The launch of LiFi products will be able to fill the gap in WiFi technology, but LiFi is not intended to replace WiFi, but as a supplement."

Friends of the business really want to beat Luo Sheng along the network cable, especially those from the WiFi Alliance.

I have never seen such a shameless person. On the one hand, he emphasizes that he has no intention of replacing WiFi, but on the other hand, he does not leave WiFi. The pain point of Diss is obvious and secret.

It is really a punctuation mark.

Luo Sheng didn’t know what the friends were thinking. He still smiled and said: “Whether we use smartphones, tablets or laptops, the biggest vision of the Côte d’Azur is that WiFi and LiFi can exist at the same time. Technically speaking, it is not difficult. A special transceiver is needed to gradually send and receive signals, and a special encoder and decoder chip are needed to convert optical signals into data, allowing users to choose between WiFi and LiFi, instead of forcing users to choose one of the two."

The technology is not difficult, the people's mind is difficult.

Obviously, this is for competitors and the WiFi Alliance, especially the WiFi Alliance. The meaning of Luo Sheng's words is obvious. Without you, I still have LiFi as a substitute solution.

There are various signs that the WiFi Alliance has regretted its operation. Maybe it will create a terminator alive and end it. This operation is just like lifting a dumbbell. Who can stand it?

Luo Sheng on the stage said eloquently: "Compared with the existing WiFi, visible light communication is safe and economical. WiFi relies on invisible radio wave transmission, and the power of the equipment is getting higher and higher, so local electromagnetic radiation will inevitably increase. , And wireless signals pass through walls, and network information is insecure. These security risks will be “swept away” in visible light communication."

As he spoke, Luo Sheng looked back at the big screen behind him, and the four characters "Sweep it all away" were enclosed in quotation marks, the charm of Chinese.

"The spectrum is more than 10,000 times larger than the radio spectrum, which means larger bandwidth and higher speed, and the network setup hardly requires any new infrastructure. The results currently in the experimental development stage show that the LED single lamp The maximum rate of visible light communication can reach 15Gbs, and it is only a matter of time before we get out of the laboratory."

"In order to achieve high speed, the Riviera will professionally optimize the current LEDs and introduce special digital signal algorithms. Of course, small-scale commercial landing can be realized in the short term, but large-scale commercial promotion is not yet possible. But in the future Obviously, visible light communication can become a major method of high-speed communication."

After a round of enthusiastic applause, the middle link entered a period for reporters to ask questions. This is not the same as the usual press conference, but this was originally a temporary press conference.

"Thanks to the spokesperson, "BBC" reporter Lawrence for the question, hello Mr. Luo, the BBC just contacted Professor Andrew from the School of Communication of the University of Edinburgh and asked about LiFi technology. Professor Andrew also raised five major questions."

This is the rhythm of direct "mid lane to lane".

Luo Sheng showed unparalleled confidence as he waited for the next article. There is a posture that I will accept the move even if you ask.

The BBC special correspondent stood standing, holding the microphone and looking at Luo Sheng on the stage, and then explained one by one according to the manuscript information just recorded:

"Question 1. At present, visible light communication and LED lamps are all single-chip, and the LED bandwidth is narrow."

"Question two. At present, silicon-based detectors in visible light communication are mainly sensitive to infrared waves, and blue light efficiency is low."

"Question three. At present, the transmitting and receiving circuits are separated, and there is a lack of dedicated chips."

"Question four, the current low efficiency of LEDs and detection chips."

"Question 5. At present, visible light communication needs to mention huge lenses in both transmission and reception."

"To sum up, Professor Andrew believes that the concept of LiFi is not optimistic. It has too many shortcomings. What is your response to this? Thank you!"

It's really the rhythm of "mid lane to lane".

Most people were stunned. There will be translators at the press conference. The netizens who watched the live broadcast also felt unconscious and stern after listening. There is reason and evidence. Professor Andrew seems to be a professional and logically organized. Very clear.

It is not easy for everyone to jump out to question and refute.

On the stage, Luo Sheng pursed his mouth and nodded repeatedly after listening, and then immediately responded:

"OK, Professor Andrew’s five major doubts really highlight his professional capabilities. First of all, I agree with his views. In fact, LiFi technology currently faces more technical pain points. Professor Andrew has said three less, but we have all sought It's a reliable solution."

The BBC reporter was taken aback, and the international friends and businessmen were also slightly surprised. Unexpectedly, Luo Sheng did not evade at all and responded positively.

I saw him confidently saying: "The specific technical details cannot be explained in a few words. Some contents are also designed to be trade secrets, but I can still briefly answer these five questions about our solutions."

"Question one, we will integrate and package lighting communication compatible LED chips, and use equalization technology to increase bandwidth."

"Question two, we will use AIGaAs-based material detectors to improve blue light efficiency."

"Question 3. Our team is developing and designing dedicated chips for visible light communication, and has made gratifying progress."

"Question four. We will use LED arrays and detector arrays to solve this problem."

"Question five. We have two options of Finier lens and blue light filter to improve the integrated acquisition."

After speaking, Luo Sheng greeted the BBC reporter with a smile. He also had to sneer. Others did not jump out to question anymore. The media people who were present could not answer this stuff. They had to ask professional scientists. They can't judge whether what Luo Sheng said is true, but judging from past examples, this is definitely correct.

"Thank you, the spokesperson, the Global Times reporter for your question, Mr. Luo, what are the promising prospects for the industrialization of LiFi visible light communication? Thank you."

Luo Sheng immediately replied:

"First of all, I want to emphasize that LiFi is not a competitor of WiFi, but a complement to each other, helping to release spectrum space.

There were a lot of people secretly slandering off the court: I believe you are a ghost, then can you not always emphasize WiFi?

Luo Sheng methodically said: "At present, visible light communication has broad application prospects. It is certain that there are no less than 50 commercial projects that I can think of. For example, it can be widely used in indoor communication and car lights. Communications, underwater communications, hospitals, nuclear power plants and other special communications and positioning systems from special manufacturers. We expect that in five years this will be an emerging market with an annual output value of US$200 billion, so we are very optimistic about the future growth of LiFi technology. prospect."

"In addition, it is certain that the next-generation flagship products of Azure smartphones and ieP tablets, which are the end consumer products of the Blue Coast, will definitely integrate visible light detection transceiver modules into them. We hope to achieve a downstream LiFi , And the uplink uses the existing WiFi, Bluetooth and infrared corresponding communication modes for back transmission, so that LiFi visible light communication can be better integrated into our lives, and the Internet can be accessed in places with real light."

After a pause, Luo Sheng smiled and added: "Of course, it depends on what the WiFi Alliance thinks, but it doesn't matter. Even without the cooperation of WiFi, LiFi can independently provide smooth and secure wireless data transmission."

It's really just a little bit of bullying and temptation. This is very uncomfortable to the ears of the WiFi Alliance.

Who is the victim?I'm afraid that WiFi is now thinking about life.

Luo Shengdu has publicly spoken about this. The next generation of Azure smartphones will integrate LiFi, which is a new Internet technology, which is really hammered. It is definitely a black technology, and other smartphone manufacturers are already in force. Lost a bit.

In fact, competitors also know that although LiFi technology still has some shortcomings, its superior transmission speed and safety and environmental performance cannot conceal its charm after all. They can also foresee that the Côte d’Azur dare to have the confidence to disclose it publicly at this time. It shows that the commercial stage of this technology is ready. With the R&D strength of the Côte d'Azur over the past decade, it is easy to overcome some of the current technical pain points of LiFi, which is like sleeping naked in the morning.

This year or next year the LiFi technology bottleneck will definitely be broken, and the future commercial prospects are unstoppable.

Not to mention Azure mobile phones, the central buildings of major cities are potential commercial partners, bringing them a new high-speed, stable, and secure network transmission solution, and enterprise-level solutions will be commercialized and brought immediately considerable profit.

The technology of the Côte d’Azur, the Côte d’Azur Lab is known as the “Bell Lab of the East” and the “Black Technology Lab”. These are the embodiment of the brand effect and goodwill accumulated over the past ten years and are trustworthy.

Time flies, and the Côte d’Azur has also established its own strong heritage.
