Galaxy Technology.
The conversation between Wang Donglai and Ren Fei continued.
Two people, one old and one young, are both rare geniuses.
At this moment, we started talking about one topic after another.
From far and wide, the content is extremely rich.
From communication technology, to aerospace prospects, to modern agriculture, the two of them can talk happily about all kinds of unrelated fields.
"Academician Wang, listening to what you just said, you know a lot about communication technology. I wonder what you think of 5G technology?"
Suddenly, Ren Feizhuangruo asked unintentionally This question.
The expression is natural and calm, as if it was a temporary act.
Faced with this question, Wang Donglai smiled softly, with a hint of sarcasm in his smile.
"Mr. Ren, you are a veteran and a pioneer in the industry. At this point, can I ask you a few questions?"
Seeing the ironic smile on Wang Donglai's face, Ren Fei didn't know why, but he had a bad feeling in his heart.
Although he wanted to refuse to answer in his heart, Ren Fei couldn't say it out loud when the words came to his lips, so he could only nodded.
"Mr. Ren, I have indeed read a lot of professional books in the field of communications before, and I understand a little bit."
"When observing the development history of communications technology in our country, I noticed Mr. Ren, can you tell me about some strange phenomena?”
Without waiting for Ren Fei to answer, Wang Donglai directly raised his question.
“Mr. Ren, why do you think the truly leading technology was not promoted in the first place?”
“For example, WIFI technology, in the 2G era, was the same as 2G It appeared at the same time, but the development of domestic WIFI is extremely slow. Why is this? "
Ren Fei's heart was finally settled.
He had a bad premonition before Wang Donglai spoke.
Sure enough, Wang Donglai asked a question that made him extremely embarrassed.
On the surface, there is nothing surprising about this problem.
However, people within the industry know very well.
The causes and consequences are all clear.
Not to mention an industry giant like Ren Fei.
The corner of his eye twitched slightly, and Ren Feicai said loudly: "The communication field is related to national security, so we must be extremely cautious. Our country's Internet technology is already lagging behind the West. If we blindly follow the pace of the West, we will easily fall into a trap." I don’t know.”
Hearing Ren Fei’s answer, Wang Donglai burst out laughing.
“Mr. Ren’s answer is really watertight!”
Actually, Wang Donglai asked this question not because he really didn’t know the inside story.
But Wang Donglai wanted to take advantage of this opportunity to see how Ren Fei would answer, and then decide what to do based on Ren Fei's answer.
In his previous life, Wang Donglai saw all kinds of rapid developments and changes on the Internet.
However, after truly understanding it, I discovered that the world is simply a grass-roots team.
In the 2G era, WIFI technology appeared together, but domestic mobile phones at that time did not have the WIFI function. The reason is very simple, that is, domestic mobile phones are working on the WAAPI standard.
At that time, the domestic Xidian Jietong directly developed a WAPI standard on the grounds that 802.11b technology was not secure enough and had encryption vulnerabilities.
After some operations, this standard became a national mandatory standard. Mobile phones connected to the domestic network must comply with the WAPI standard.
If it were just like this, forget it, but this WAPI standard patent is very nonsensical and has no technical content at all. Anyone with a discerning eye can see that it is an 802.11b case. As long as the mobile phone is compatible with 802.11b, it is theoretically compatible with WAPI.
However, Xidian Jietong, which controls this patent, is naturally asking for a sky-high price. The asking price is so high that companies such as Nokia, Apple, and Samsung cannot accept it. They directly choose to cut off the WIFI function in their mobile phones. Willing to accept Xidian Jietong's sky-high patent clamp.
This also led to the fact that before 2009, national bank mobile phones did not have WIFI function at all, which naturally led to the proliferation and prosperity of parallel-imported mobile phones in the market.
Xidian Jietong thought that it could make a lot of money by holding the patent, but it turned out that when the WAPI standard was just beginning to take shape, 802.11g appeared, followed closely by 802.11i, and in 2007 In 2011, 802.11n appeared, and the gap between WAPI and international counterparts became wider and wider.
It wasn't until 2009 that things turned around. The superior authorities compromised and allowed WAPI-compatible mobile phones to be put on the market.
Xidian Jietong holds relevant patents, and this is the mandatory standard for domestic mobile phone access to the Internet, so it still relies on this patent to collect high royalties from international brands such as Samsung, Apple, and Nokia.
This is just the 2G era.
It’s the 3G era.
TD-CDMA technology was first developed by Siemens. However, after it was developed, it was found that the technology’s networking was complex, and the coverage radius and speed were not ideal enough. In the 3G standard competition, It failed miserably and lost to the WCDMA standard jointly led by Ericsson and Nokia, thereby determining the international standard for 3G.
After Siemens failed in the competition, it transferred this technology to the Telecommunications Science and Technology Research Institute of the Ministry of Posts and Telecommunications for free. After a simple rectification by the institute, it asked Datang Corporation, which is directly affiliated with it, to transfer it in 1998. This technology is submitted to the International Telecommunications Union as a TD-SCDMA standard with independent intellectual property rights.
Regarding this technology, it has been commercialized on a small scale before. Initially, it only covered a dozen cities. I want to see the effect.
The result was naturally no surprise.
It was a complete mess!
In order to promote this technology, Datang, under the banner of "independent and controllable", on the one hand requested to postpone the listing of 3G in China so as to gain time to perfect these technologies. At the same time, the three operators are required to use different standards. As the strongest operator, China Mobile naturally assumes the task of supporting domestic products.
The final result is very obvious. Domestic 3G was launched very late. Construction only started in 2010. Not to mention 3 years later than its international counterparts, the completed TD-SCDMA is still completely unusable. .
Therefore, after China Mobile issued its 3G license, it immediately lobbied higher-level departments to issue a 4G license and began secretly building a 4G network, which also led to a result.
Domestic mobile Internet has not been in the 3G era for a long time and is about to enter the 4G era.
With the memories of later generations as evidence, Wang Donglai knew one thing even more clearly.
That is, 5G is not as good as advertised.
The three major operators invested a huge amount of money and just established the 4G communication foundation. As a result, they started to promote 5G crazily. However, after 5G came out, the benefits originally promoted were reduced by more than half.
Although it is not stated explicitly, many people have a feeling that 5G has been promoted too fast, causing serious unnecessary waste.
This was the purpose of Wang Dong asking Ren Fei this question before he came.
If Ren Fei can speak out about the calculations in these popular fields, it will prove that Warwick did not mean it.
But if not, it would be hard to say.
“Mr. Ren, compared with 3G, 4G has brought great changes, which can be seen from the current development of the Internet market.” “3G supports Qualcomm’s CDMA, and the technology is mainly based on As a family, everyone can see that Qualcomm is enjoying a lot of money because of this technical standard, and they all want a piece of the pie. Mr. Ren will not deny this, right?”
Wang Donglai looked at Ren Fei and asked seriously.
Ren Fei thought for a moment, then nodded and admitted.
“In order to get a share of the pie, major companies have shown their true capabilities and paid huge costs, and they have indeed developed 4G technology.”
“Any In general, in the field of domestic communications, your company is First of all, I think you should be very clear about the situation in this regard. Each company has put forward its real skills for 4G, and I am afraid that they have exhausted their knowledge reserves. Then in the next 5G research and development, they can still do it. Innovate again? ”
Without waiting for Ren Fei's answer, Wang Donglai said to himself: "I don't think so. After seeing the success of 4G, the remaining people will become even more crazy and want to profit from it, from the fallen Ericsson and Nokia." "At this time, interest has become the biggest dominant factor."
"Once the phenomenon of interest as the dominant factor appears. , then many people will not delve into the technology. As long as they can circumvent the 4G patent, it will be promoted as 5G. "
"But in fact, this kind of 5G is of no use at all."
“The functional improvements that can actually be achieved in software must be implemented through hardware, and the cost will double. This is not a technological iteration at all.”
"Technology needs to be accumulated, and even requires painstaking study. How many technological innovations are made in a hurry, and how many of them will be truly good technologies."
Hearing this, Ren Fei looked a little unhappy. nice.
He naturally understood what Wang Donglai meant.
"Academician Wang seems not to be optimistic about 5G technology?" Ren Fei suppressed the anger in his heart and asked.
“5G technology cannot be said to be wrong, but in my opinion, it is not suitable for large-scale promotion.”
"2G entered 3G and entered the era of intelligence."
"From 3G to 4G, network speeds have soared. Whether it is games, videos, music, or other Internet services, they have been greatly improved. Okay.”
“So, when it comes to 5G, will the 4G network speed be increased several times?”< br>
“Even if the Internet speed is increased several times, will there be such a big improvement in the sense of using the Internet?”
“Games can be opened at a click, and videos can be played at a click. At most, it can only It only saves a little loading time than before, but the huge cost is extremely expensive.”
"In the market economy, this approach is completely inconsistent with common sense."
"In my opinion, 4G should be the mainstay, 5G should be the supplement, and satellite communications should be the supplement. This is the direction we should develop. "
Ren Fei listened patiently, shook his head, did not agree with Wang Donglai's words, and said aloud: "Academician Wang, you have your thoughts and reasons, and I will also share my thoughts."
"The 2G era is the text Internet, the 3G era is the picture Internet, the 4G era is the video Internet, and what about 5G ? ”
“In my opinion, it is an era of interconnection of everything.”
"I won't go into detail about the concept of the Internet of Everything, Academician Wang should also be able to understand it."
"Once 5G really breaks through, then from the national level such as people's livelihood, medical care, military, etc., for the industry The efficiency and improvement are significant.”
“Maybe at the civilian level, there are still some shortcomings in 5G application scenarios, but the flaws cannot be concealed. Yu, I think no one will deny the advancement of 5G.”
“We are already in a catching-up position. If new research directions emerge, we cannot seize the opportunity and time. , then we will only fall further behind.”
“Some things can’t be known until they are done.”
"If you are worried about right or wrong, not doing it is tantamount to choking and giving up eating. It is extremely stupid!"
Wang Donglai also shook his head, not at all because Ren Fei is the founder of Warwick, a giant company that is the leading company in the field of transportation. And there is no trace of restraint.
"Mr. Ren, I have made my attitude very clear just now."
"Judging from the current development situation, as long as 5G technology is forcibly launched, there will inevitably be measures to Situations in which backward technologies break through patent restrictions and bring higher costs appear.”
“Then. The second time is that 5G only blindly pursues high network speed, low latency and large connections. Regarding the application scenarios of 5G, although it plays a major role in people's livelihood, medical care, national defense, etc., for a new thing that has not yet appeared, It is undoubtedly an immature idea to have such huge expectations.”
"Finally, mobile communications and WiFi are a game between the two major ecosystems of ct and it. The commercial value of WiFi is higher than that of mobile communications." The propagation distance of base stations is short, which means that the distribution of 5G base stations is wider than that of 4G. At the same time, the power consumption of 5G base stations is 4. 2.5-3.5 times that of G, plus the density is higher than that of 4G, the power consumption will be much higher than that of 4G. "
"The development of technology has its own rules. If you want to violate it. This rule is bound to have backlash!"
Ren Fei clapped his hands with a smile on his face, showing no sign of being offended or irritated.
"The ancients said: Listening to your words is better than ten years of reading. The ancients have never deceived me!"
"I learned a lot from my conversation with Academician Wang today."
"Although you and I have different opinions and views, things in the world are just like that, and there is no definite answer at all."< br>
“As for the debate on 5G technology, I, an old man, will not I’ll argue with you.”
“It’s right for both the public and the mother-in-law, but which one is more right can only be left to time.”
“To be honest, I also look forward to Academician Wang developing 5G technology, which will give me more knowledge.”
"It's still the same sentence, technology is technology, and the route is the route. We are the subject of the former, but we don't have much autonomy. The above ideas are the most important."
After saying this, Ren Fei stood up.
Two hours have passed since the two met.
After all, Ren Fei is a bit older and has traveled all the way here. There is an obvious look of exhaustion on his face.
Wang Donglai stood up and said loudly: "Mr. Ren, I have benefited a lot from my exchange with you today."
"To tell you the truth, one of the reasons for Galaxy Technology's space rocket project is to launch communication satellites, establish a domestic satellite communication system, and supplement communication signal problems."
"With 4G as the The main body, 5G as an auxiliary, and satellite communications as a supplement are our best development routes.”
Ren Fei did not expect that Wang Dong would still insist on this at this time, so he said seriously: "Academician Wang, this is a matter of route. I have already said that the decision-making power does not lie in the hands of the company."
< br>"You are a smart person, you should be able to understand what I mean!"
After saying that, Ren Fei turned around and left.
When Yu Dazui left, he looked at Wang Donglai with extremely complicated eyes, including admiration and a hint of shock. (End of this chapter)
