Chapter 696 CDMA Technology in the main text

Next chapter

After eating the open-air barbecue, everyone chatted for a while, everyone welcomed Lin Qiangsheng's arrival, Harvey's wife was the one who talked to Lin Qiangsheng the most, she was very interested in China, and often asked some strange questions, such as why the Chinese make chopsticks, why there is the Great Wall, and the origin of the names of those dynasties in China, why are they different from the names of the emperors who founded the country.

"Mr. Lin, you have ambitions for Qualcomm, do you know what kind of company it is?" Franklin and Lin Johnson said, with some condescension and disdain in their eyes.

The four men got together and began to talk about something substantial, and Franklin and Harvey White's posture had the flavor of a three-class triage.

Lin Qiangsheng inexplicably felt that these people had a sense of superiority of some Westerners in their psychology, thinking about Qualcomm's arrogant attitude towards China in his previous life, he instantly understood the origin of Qualcomm's policy, which was influenced by these founders.

However, who let the family have the technology, he still said: "I am very optimistic about the future of CDMA mobile communication technology, as far as I know, Qualcomm has begun to develop CDMA code division multiple access technology, I think the future of this spread spectrum communication based on carrier modulation and multiple access technology is very promising, now Motorola is still focused on the development of analog standards, they are not interested in new technology at all, but digital technology has begun to emerge, they do not know it!"

If CDMA is popularized in the United States, it will be easy to win the market from Motorola with its advantages of being more advanced than analog technology! I am willing to help Qualcomm promote CDMA to the American public, and my future digital mobile phones of Dongxing Communications will also adopt CDMA standard, my participation will definitely make Qualcomm more accepted by the market faster! ”

Lin Johnson looked at the silent attitude of Jacobs, Franklin and Harvey White, and then said: "At present, you are the only ones in the United States who have seen the future development direction, and have clearly formulated the research and development process of CDMA. I think for the sake of unnecessary competition for everyone, wouldn't it be better for us to join forces to develop the CDMA business together? ”

Harvey White admired this young man very much, and he showed his kindness to Lin Johnson like his wife, and he asked curiously: "Lin, how much do you know about CDMA technology?" ”

Lin Qiangsheng nodded to Harvey White and said, "Just like I said." CDMA is a spread-spectrum multiple access digital communication technology that is more advanced than the analog technology that dominates the market today! It is a unique sequence of codes that establishes the channel, which is like imagining the bandwidth as a big house, where everyone will enter this only room, and if they speak a completely different language, they can clearly hear their companions, so that there will be very little interference from other people's conversations.

The air in the room can be thought of as a broadband carrier, different languages are coded, and code division multiple access allows us to continuously increase the number of users. Until the whole background noise restricts us. ”

He looked at the surprised expressions of the three and said, "But if we can control the signal strength of users and develop advanced control technology, we can accommodate more users while maintaining high-quality calls!" ”

Facing the eyes of the three people who gradually became strict, Lin Qiangsheng said: "And as far as I know, the European G** R&D team has determined their technical standard, which is based on the narrowband TDMA standard. It allows up to 8 groups of calls on one radio at the same time. And my Dongxing communication company real yàn room studied CDMA and European technology, and we found. Through the comparative analysis of Guò technology, the call quality of CDMA will be higher than that of G**, and the interference of CDMA will definitely be smaller than that of G** when making a call in the same environment, and the call quality of CDMA technology is higher; The second advantage is that the radiation of the mobile terminal is small, because the CDMA adopts advanced power control technology. Therefore, the radiation of mobile devices must be much smaller than G**, which is undoubtedly more beneficial to human health and meets the requirements of green environmental protection; Third, CDMA has a wider bandwidth, and it can transmit more Jù than G**! ”

Lin Qiangsheng smiled and spread his hands to the three of them. Said: "With such excellent features, I believe that the future CDMA technology will be promising, as an investor, I see, I come!" ”

Franklin was a little surprised by the depth of Lin Johnson's understanding, and he said: "I didn't expect your communications company to have such a deep research on this technology, and it also compared the G** technology of Europeans!" ”

He asked curiously, "Where are you in your research, and which scientist is working for you?" ”

Jacobs didn't expect Lin Qiangsheng to know so much about CDMA technology, and listen to the other party's meaning, his R&D department also conducted preliminary research on this technology, as for how the Europeans did G**, they only heard about it, and they didn't know about it, but they didn't expect Lin Qiangsheng to get the information of G**, if this is the case, the other party's research process is likely to be more in-depth than them!

Lin Qiangsheng pretended to smile mysteriously and shook his head, and did not answer Franklin directly, in fact, where did he have any experts. There are a few giants in the field of communications in China, but the knowledge of those people is still some distance from the world's cutting-edge science and technology, and several of them are still working in important research departments of the country, responsible for important projects, and the things he said are just what he saw in his previous life.

But now in the 80s, when the field of digital mobile communications was just making progress, these technical features are unknown to most people.

The three of them walked to the side and discussed in a whisper, and finally Jacobs said to Lin Qiangsheng: "Lin, we will seriously consider your proposal, but please don't reveal the contact between the two of us before that!" ”

Due to the U.S. government's commercial restrictions on more confidential digital communication technologies, Qualcomm is now only secretly developing CDMA. Jacobs and others wanted to make a splash after the U.S. government opened up this field, but they didn't expect to kill Li Qiangsheng halfway.

Of course, the U.S. side is only turning a blind eye to private commercial research and development, but if Lin Johnson really takes a stake in Qualcomm, then he will have to face some scrutiny and special treatment, because Jacobs and others are indeed extraordinary, and they have cooperation with the U.S. side itself.

On the way back for the two, Lin Qiangsheng saw Esther smiling happily all the time, and asked, "Is there anything funny, beauty?" ”

Esther laughed and said, "Harvey White's wife is very interesting, she really wants to travel to China, I told her some of what I saw and heard in China, and her surprised expression was funny!" ”

Lin Qiangsheng asked strangely, "Is it that interesting?" ”

Esther nodded and said, "Yes, I was also surprised when I first arrived in China, for example, there are traffic jams in China, when I first arrived in China, I saw the scene of work, that scene shocked me, I saw so many bicycles for the first time, China is really a veritable bicycle kingdom!" ”

Lin Qiangsheng shrugged his shoulders, not knowing whether the title was good or bad, he said: "Bicycles are more environmentally friendly!" ”

Ace nodded and said: "Of course, I admit this, but more than 100,000 people ride bicycles to work every day, I can only see in China, cycling in Europe and the United States is for fitness, and Chinese cycling is just for commuting, I found that you usually rarely ride, so no one uses bicycles to fitness, this is not the same in a bicycle kingdom like the Netherlands, the Dutch body is great, cycling is also fast, interesting is that it is also called the bicycle kingdom!" ”

Lin Qiangsheng asked, "Where did you know that?" ”

Esther grinned and said, "I heard it from Mrs. Harvey White, her father is from the Netherlands!" ”

Lin Qiangsheng nodded, thinking of investing in Qualcomm without eyebrows, maybe he could ask Esther to see what she thought, so he asked: "Esther, you know that I want to invest in the Qualcomm company founded by Jacobs this time!" ”

Esther nodded and said: "Of course you know, this company is currently trying to win the contract of the US military, they are now just a small company renting an office in Los Angeles, and the research office is still located in Jacobs himself's Linka forced T company, this company and M/A company have merged to strengthen it in satellite communication technology!" ”

Lin Qiangsheng asked: "Esther, how can I invest in Qualcomm, now Jacobs they have scruples about my Chinese identity!" ”

Esther looked at Lin Johnson and asked, "Lin, are you really optimistic about this high technology?" ”

Lin Qiangsheng nodded and said, "Of course, the future development space of the communication market is very large, and the profits are very high!" (To be continued.) For mobile phone users, please visit wènhttp://mnet
