Chapter 425: CDMA technology

Popular recommendation:,,,,,,,

The first generation of analog cellular communication networks is the beginning of the mobile communication era. Although this new market is growing rapidly, the total amount is still very limited. What's more, the European and American communication equipment giants have already taken the lead in conducting in-depth research and development. So Li Xuan doesn't care about Big Brother's products.

But as a past person, he knows very well the bright future of the mobile communication industry. Dongfang Group is unwilling to invest too much in crt color TV, a technology that is beginning to decline, but it has never been relentless in its investment in high-tech industries.

For example, in the liquid crystal industry, which will replace crt technology as the mainstream display technology in the next few decades, Li Xuan invests no less than 100 million US dollars in research and development every year. This is 100 million US dollars. Even after 30 years, few companies have reached such a scale of scientific research investment! What's more, the purchasing power of the US dollar today is several times higher than that of the US dollar thirty years from now!

And let Li Xuan willing to spend a lot of money without any regrets, also including mobile communication technology. Dongfang Group has already skipped the 1g analog era and directly put the treasure in the future 2g digital era.

In another time and space, two companies, Microsoft and Intel, are hostile to the rest of the industry because of their dominance in the software and hardware fields of the IT industry, respectively.

But there is one company that is more brutal than either of them, and has the power to make the world's mobile giants crawl at its feet. Any enterprise that wants to join the competition in the field of mobile communication must pay enough protection fee to it!

The company's name is Qualcomm, and it holds key patents related to the entire cdma wireless communication standard. Later, China's Development and Reform Commission issued the largest and largest anti-monopoly fine in history - 6 billion yuan. The object of the penalty is this San Diego-based Qualcomm.

After the first generation of analog cellular communication systems went into commercial operation in the early 1980s, users soon began to grow at a dangerous rate. This forces the major communication equipment manufacturers. A new technology must be developed to expand the capacity of their communication network.

So adopt tdma (time division multiple access) technology of digital coding to speech, be applied to the cellular communication network gradually. Qualcomm has developed a more advanced cdma (code multiple access) technology based on the idea of ​​tdma.

Compared with the European gsm standard, the cdma technology introduced by Qualcomm not only has a larger network capacity, but also has better call quality.

But the biggest disadvantage of cdma technology is that its research and development progress is a step slower. When Qualcomm has just started large-scale technical testing, gsm networks have already been put into commercial operation in Europe. And quickly blossomed all over the world.

The competition between cdma and gsm, although it has always been at a disadvantage in the early days. However, relying on more advanced technology, cdma has gradually recovered the situation. And it broke out completely in the 3g era.

And Qualcomm has successfully built an iron wall outside the patent pool of cdma technology with more than ten years of patent layout, becoming the supreme emperor in the field of mobile communications in the 3G era. Any telecom operators and mobile phone manufacturers who want to make a difference in the 3G era have to pay high patent fees to Qualcomm.

Li Xuan understands how bad Qualcomm will be after 30 years. So he was very decisive to suppress this company that had not even been established in advance. Qualcomm had to wait until this year. That is, in 1985, it was founded by Dr. Owen Jacob and six other people of insight.

And Li Xuan had already started poaching people two years ago. Among all the seven founders, the most important is undoubtedly Jacob, who is known as the "Godfather of Qualcomm", and Professor Andrew Viterbi, the chief scientist of Qualcomm.

Li Xuan never considered digging the core founder of Qualcomm's entrepreneurial team, Owen Jacob, to the Oriental Group. Because this person is a famous dictator and tyrant in the American IT industry in later generations. And such people often have a strong desire to control. I would never want to live under someone else for a long time.

Later, when Jacob retired, he directly appointed his son to succeed him in controlling Qualcomm. This is definitely a very rare thing in the US IT industry. There was a public outcry at the time. It can also be seen that Jacob's control over Qualcomm has reached an incomparable level.

Of course, after Jacob Jr. accepted Qualcomm, the company's business continued to grow by leaps and bounds. But in Li Xuan's view, 90% of the credit actually goes to old Jacob. As soon as little Jacob took office, the 3G era of mobile communication followed. Qualcomm, which holds thousands of patents, can make a lot of money even if it is managed by a pig.

So there is no doubt about the talent of old Jacob, but he is only suitable for being his own boss, and let others follow his orders unconditionally. It was enough for the Dongfang Group to have Li Xuan, a person who could issue orders, so the target he chose to attack was another Professor Andrew Witerby.

As early as two years ago, the Oriental Research Institute offered Professor Andrew Viterbi a favourable treatment that he could not refuse, poaching him from the University of California, San Diego to the research and development center of the Oriental Research Institute in Silicon Valley.

As the saying goes, every line is like a mountain. Li Xuan was engaged in the field of chip design in his previous life, and his understanding of wireless communication technology is very limited. He decided to know only a few terms such as tdma (time division multiple access) and cdma (code division multiple access).

The so-called code multiple access (cdma) refers to the signals used by different users to transmit information, which are not distinguished by different frequencies or time slots, but by different coding sequences.

Li Xuan can only provide such a concept, but for real experts, it is enough to have such a research idea. How to use coding to distinguish, requires developers to experiment again and again to explore.

The rest of Li Xuan's work only needs to provide enough research and development funds for Professor Viterbi's cdma project team. Since its establishment, the cdma project team has been one of the highest priority projects in the Oriental Research Institute.

After Liu Wei entered the Deep Sea R&D Center of the Oriental Research Institute last year, he happened to be assigned to the Asian development team of the cdma project. And he just completed a technology research and development not long ago, which solved a key difficulty in cdma technology, making it a small step towards the final practical use.

Li Xuan reviews the work report submitted by the Oriental Research Institute every month, and the progress of the cdma project has always been one of his focuses, so he has a lot of impression of the name Liu Wei.

After Li Xuan had a brief conversation with the three employees, he turned around and walked towards the corner where Zhong Chuhong was, while the three behind him were caught in a huge surprise.

"Liu Wei, you really hide it! Fang Qianqian, after you go back, quickly relay Li Sheng's comments to your father to see if he will continue to oppose your relationship with Liu Wei!" Liu Chang stretched out his hand fiercely Hammered his friend.

After continuous expansion, the Oriental Group has more than 50,000 employees. It is definitely something to be very proud of to be able to remember your name from so many people, Li Sheng!

Liu Wei smiled, but he couldn't hide the excitement in his eyes. And Fang Qianqian looked at her boyfriend with a slightly obsessive look, she was very proud that she did not choose the wrong person.

Just as Liu Chang jokingly said just now, Fang Qianqian also felt relieved that Li Sheng valued her boyfriend. Li Sheng's golden words were enough to offset the resistance from her family.

Who is Li Xuan, that is the famous "God of Wealth Li"! If you doubt anyone, don't doubt the vision of "God of Wealth Li"! This is the consensus of all investors in Hong Kong!

Fang Qianqian's father is actually a very realistic businessman. He has stopped expressing his opposition recently, and his daughter is dating Liu Wei, a mainland boy. Because Liu Wei is showing great value in himself.

The reason why Fang's father was able to win the company's videotape order was the help of Liu Wei's friend Liu Chang. The reason why he quickly obtained the loan needed to expand his investment from Jiahua Bank was also due to the help of another friend of Liu Wei, Han Ying.

"Li Sheng just said that he will pay for today's consumption! Let's go pick a bottle of the most expensive wine here to celebrate while Li Sheng hasn't checked out yet!" Liu Chang said with a smile.

He and Liu Wei have developed a deep friendship since the two were selected to come to Hong Kong to participate in the "Dongfanghong" exchange program together a few years ago. Although there is a little jealousy in his heart now, the kid next to him has a double harvest in love and career~www.readwn.com~ But Liu Chang is more happy for his friends!

"Who were those people just now?" As soon as Li Xuan walked back to his position, Zhong Chuhong asked curiously.

"Several employees of the company, don't worry about such details! I just put my face on stage to sing to express my feelings, shouldn't you be moved now!" Seeing that she missed the point, Li Xuan deliberately made a very depressed expression expression.

"I was moved just now, but who made it take so long for you to come back. The moved mood has calmed down!" A sly smile appeared on Zhong Chuhong's face.

"Do you think I should be direct and let go of these three guys who destroy the romantic atmosphere!" Liu Xuan squinted in the direction of Liu Wei and the three, and said angrily.

"I don't seem to have heard this song "Two Butterflies" before?" Zhong Chuhong asked with a smile.

"Authentic and original, today is the first time this song has been released! Do you think your husband is full of sincerity!" Li Xuan said slightly with interest. (To be continued...)
