Global Monopoly of Technology

Chapter 602 [Technical heritage of the Cote d’Azur (another four-K chapter)]

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

A clatter.

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

And mastered a technological commanding heights.

Cote d'Azur has mastered a new black technology. The more cutting-edge technology is, the more advanced it is, and Cote d'Azur has once again proved itself to be the leader of cutting-edge technology.

Some foreign media people applauded weakly, especially European media people who don't know how to describe the complicated mood at the moment. Luo Sheng made it clear that this technology was invented by Europeans. I don't know whether to be happy or sad.

No, this is like a stab in the chest for Europeans, deeply rooted in the hearts of the people.

LiFi technology is now owned by the Côte d'Azur. Even if Hyland Haas is poached, LiFi technology will not be taken away, because PureLiFi is already owned by the Côte d'Azur.

What's more, Hyland Haas may not appreciate it. If it wasn't for the short-sightedness of European capital at the beginning, how could it be possible to pick up such a huge bargain for the Côte d'Azur?

It is worth mentioning that the attention of the outside world is now focused on the Côte d'Azur, and almost no one pays attention to another technology giant in Huaguo, which also paid a professor named Eldor from Turkey in the same year. Under his command, his technical theory has played a crucial role in the research and development of 5G technology, and no one has paid attention to this unusually low-key but equally powerful technology company.

"What's the difference between LiFi and WiFi? Besides the advantage of providing lighting, what does it do differently?"

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

"There are five major advantages. First, 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 smart home devices, refrigerators, cameras and even watches and other devices that can use WiFi, interviews are being conducted one after another. In addition to the data diversion of mobile networks, traffic congestion will become more and more serious, and the quality of information transmission will inevitably be affected. LiFi uses light wave frequencies , its bandwidth is more than 10,000 times the RF bandwidth, and does not conflict with WiFi."

"The second is the protection of data.

Radio waves can penetrate walls and ceilings, but light cannot, which can reflect the difference in data protection between LiFi and WiFi. A hacker or intruder outside a building can transmit through an indoor computer via WiFi, but through The information transmitted by LiFi can only be accessed within the range of lighting such as LEDs. "

"The third is application security. WiFi will generate electromagnetic interference, affecting aircraft equipment and medical instruments. Power plants, oil and gas drilling are potentially dangerous, and LiFi, as mentioned earlier, is safe and will not bring Electromagnetic Interference."

"The fourth is speed. The 802.11a/g wireless protocol standard WiFi can provide a data communication rate of 54Mbps, and there are currently technologies that can increase the speed to 1Gbps. However, PureLiFi's laboratory data shows that the father of LiFi, Hiland Ha Professor Si's team has achieved a speed of 3Gbps using a monochromatic light source, and the full-color, that is, red, blue, and green LED lights can be increased to 9Gbps, and I look forward to the day when it goes out of the laboratory for commercial use."

“The last thing is throughput. LiFi has far more throughput than WiFi, and the 2.4GHz and 5GHz bands are now saturated with existing devices such as cordless phones, Bluetooth and WiFi, not to mention augmented reality, virtual reality, autonomous driving New things like cars and billions of IoT devices.”

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

Now Luo Sheng came out to promote this technology in person, and it suddenly became a hot topic in the industry, and the attention he received skyrocketed. Hyland Haas, who was behind the scenes, was also very happy when he saw 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, that is, VLC, which can transmit data using light-emitting diodes, that is, light waves of LED bulbs, and can provide lighting services and wireless at the same time. It is connected to the Internet and does not generate electromagnetic interference, which can better protect data security and help alleviate the congestion problem caused by today's explosion of network traffic.

From these aspects, the development prospects of LiFi do have great imagination.

Coupled with the support of the Côte d'Azur 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.

Is Luo Sheng subverting the industry through technological innovation?

On the stage, Luo Sheng smiled kindly and said, "Wi-Fi 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 for independent working days, but the security is not great. Reliable, and it can be seen that WiFi also has its shortcomings, so a new standard was born: Fi products will be able to fill the technical gap of WiFi, but LiFi is not intended to replace WiFi, but as a supplement.”

The friend business really wanted to beat Luo Sheng along the network cable, especially the people from the WiFi Alliance.

I have never seen such a shameless person. On the one hand, he emphasizes that he does not intend to replace WiFi, but on the other hand, the three sentences are not separated from WiFi, which is a pain point in Diss.

Really can't believe a punctuation mark.

Luo Sheng didn't know what friends and businessmen were thinking, but he still smiled and said, "Whether we use smartphones, tablets or laptops, the biggest vision of the Cote d'Azur is that WiFi and LiFi can coexist. Technically, it's not difficult, only A special transceiver is needed to gradually send and receive signals, and then a special encoder and decoding chip is needed to convert the optical signal into data, allowing users to choose between WiFi and LiFi, rather than forcing users to choose one or the other.”

The technology is not difficult, but the human heart is difficult.

Obviously, this is for the 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 backup solution.

There are all kinds of signs that the WiFi Alliance has regretted its own rude operation. Maybe it will create a Terminator to end itself. This operation is like lifting dumbbells in the gym, who can stand it.

Luo Sheng on the stage said eloquently: "Compared with existing WiFi, LiFi is safer and more economical in visible light communication. WiFi relies on invisible radio wave transmission, and the power of the equipment is getting bigger and bigger, and local electromagnetic radiation will inevitably continue to increase. , and the wireless signal passes through the wall, and the network information is not safe. These security risks will be 'swept away' in the visible light communication."

While speaking, Luo Sheng looked back at the big screen behind him. The four big characters "sweep away" were put in quotation marks, the charm of Chinese.

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

"In order to achieve high speed, Côte d'Azur will professionally optimize the current LEDs and introduce special digital signal algorithms. Of course, small-scale commercial implementation can be achieved in the short term, but large-scale commercial promotion is not yet possible, but in the future , visible light communication is obviously a major way to become high-speed communication."

After a burst of warm applause, the middle part entered a time for reporters to ask questions, which was different from the usual press conference, but this was originally a temporary press conference.

"Thanks to the speaker, "BBC" reporter Lawrence for your question. Hello, the BBC has just contacted Professor Andrew of the School of Communication at the University of Edinburgh and asked about LiFi technology. Professor Andrew also raised five questions."

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

Luo Sheng's look of waiting for the next sentence shows unparalleled confidence, and there is a kind of posture that you can ask, and I will answer.

The BBC correspondent standing off the field, holding a microphone, glanced at Luo Sheng on the stage, and then explained one by one according to the manuscript information just recorded:

"Question 1. Currently, both visible light communication and LED lamps are single-chip, and the LED bandwidth is narrow."

"Question 2. At present, silicon-based detectors in visible light communication are mainly sensitive to infrared waves, and the blue light efficiency is low."

"Question 3. At present, the transmitting and receiving circuits are separate, and there is a lack of dedicated chips."

"Question 4. The current LED and detection chips are inefficient."

"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 "middle lane to lane".

Most people were stunned for a moment. There were translators at the press conference. Netizens who watched the live broadcast also felt a sense of ignorance. There was reason and reason. The character of Professor Andrew seems to be a professional and logical. Exceptionally clear.

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

On the stage, Luo Sheng pouted and nodded after listening. After a while, he responded:

"OK, Professor Andrew's five questions really highlight his professional ability. First of all, I agree with his point of view. In fact, the current technical pain points of LiFi technology are more than that. Professor Andrew said three less, but we have all sought It's time for a solid solution."

The BBC reporter was stunned for a moment, and the international friends and businessmen were also slightly stunned. Unexpectedly, Luo Sheng did not evade at all, and responded positively.

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

"Question 1. We will integrate and package lighting communication compatible LED chips, and use equalization technology to increase bandwidth."

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

"Question three, our team is developing and designing special 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 5. We have two optional solutions of Fresnel lens and blue light filter to improve the integrated acquisition."

After speaking, Luo Sheng greeted the BBC reporter with a smile. He had no choice but to laugh a little, and the others didn't jump out to question any more. The media people present couldn't answer this thing, so he had to let professional scientists They can't judge whether what Luo Sheng said is true, but judging from past examples, it must be true.

"Thank you for the speaker. The Global Times reporter asked, Mr. Luo, what are the prospects for the industrial application of LiFi visible light communication? Thank you."

Luo Sheng immediately replied:

"First of all, I want to emphasize that LiFi is not a competitor to WiFi, but a complement to help free up spectrum space."

Off the court, many people secretly slandered: I believe you are a ghost, can you stop stressing WiFi all the time?

Luo Sheng said in an orderly manner: "At present, visible light communication has broad application prospects. I can only think of no less than 50 commercial projects that can be implemented. For example, it can be widely used in indoor communication, car lights. Specific communication and positioning systems for special manufacturers such as communications, underwater communications, hospitals, nuclear power plants, etc. We expect this to be an emerging market with an annual output value of $200 billion in five years, 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, the terminal consumer products of the Côte d'Azur, will definitely integrate visible light detection transceiver modules into them, and we hope to achieve a downlink LiFi , And the uplink uses the existing WiFi, Bluetooth and infrared corresponding communication modes for backhaul, so that LiFi visible light communication can be better integrated into our lives, and the Internet can be really realized where there is light."

After a while, Luo Sheng suddenly 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 transmission of data."

It's really just a few words with coercion and temptation, which is extremely uncomfortable to listen to the ears of the WiFi Alliance.

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

Luo Sheng has already said this publicly. The next-generation Azure smartphone will integrate LiFi, a brand-new Internet access technology. It is a real hammer. It is definitely a black technology. Lost a bit.

In fact, competitors also know that although LiFi technology still has some shortcomings, its superior transmission speed and safe and environmentally friendly performance cannot hide its charm. This shows that the commercial stage of this technology is ready. With the technical research and development strength of the Cote d'Azur in the past ten years, 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 bottleneck of LiFi technology 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 considerable profit.

The technology of Côte d'Azur, the Côte d'Azur laboratory is known as the "Oriental Bell Lab" and "Black Technology Laboratory", which are the embodiment of the brand effect and goodwill accumulated over the past ten years, and they are all trustworthy.

As time flies, the Côte d'Azur has established its own strong heritage.
