Chapter 425: CDMA Techniques

The first generation of analog cellular networks was the beginning of the mobile communications era, a new market that was growing rapidly but was 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. Therefore, Li Xuan is not interested in Big Brother products.

However, as a person who has come before, he knows very well the bright future of the mobile communication industry. The Eastern Group is reluctant to invest too much in CRT color TV, a technology that is beginning to decline, but it has never been soft on its investment in the field of high-tech industries.

For example, in the LCD 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 R&D every year. That's $100 million, and even in 30 years, very few companies will have reached such a scale of investment in scientific research! Not to mention that the purchasing power of the dollar today is several times higher than that of the dollar in 30 years from now!

And what makes Li Xuan willing to spend a lot of money without regrets also includes mobile communication technology. The Eastern Group has already skipped the 1G analog era and directly pressed the treasure in the future 2G digital era.

In another time and space, Microsoft and Intel are two companies that are hostile to other companies in the industry because they dominate the software and hardware fields of the IT industry, respectively.

But there is one company that is even more brutal than the two of them, and has the power to make the giants of the world's mobile communications field prostrate at its feet. Any company that wants to join the competition in the field of mobile communications must pay enough protection money to it!

The company's name is Qualcomm, and it holds key patents related to the full range of CDMA wireless communication standards. Later, China's National Development and Reform Commission issued the largest and largest anti-monopoly fine in history -- 6 billion yuan. The penalty was imposed on Qualcomm, a San Diego-based company.

The first generation of analog cellular communication systems, which were put into commercial operation in the early eighties, soon began to grow at an extremely dangerous rate. This has forced major communication equipment manufacturers to: A new technology had to be developed to expand their communications network.

As a result, TDMA (Time Division Multiple Access) technology, which uses digital coding for voice, is gradually being applied to cellular communication networks. Qualcomm has developed a more advanced CDMA (code multiple address) technology based on the idea of TDMA.

Compared with the European GSM standard, the CDMA technology launched by Qualcomm not only has a larger network capacity, but also has better call sound quality.

But the biggest disadvantage of CDMA technology is that it is a step slower in its development schedule, and when Qualcomm is just beginning large-scale technical testing, the GSM network is already in commercial operation in Europe. And quickly blossomed and bore fruit all over the world.

The battle between CDMA and GSM has been at a disadvantage in the early days. But the CDMA relied on more advanced technology and gradually salvaged the situation little by little. And it has completely exploded in the 3G era.

With more than ten years of patent layout, Qualcomm has successfully built an iron wall outside the patent pool of CDMA technology, becoming the emperor in the field of mobile communications in the 3G era. Any telecom operator or mobile phone manufacturer that wants to make a difference in the 3G era has to pay high patent fees to Qualcomm.

Li Xuan understands very well how rebellious Qualcomm is after thirty years. So he was very decisive to suppress this company that had not even been established in advance. Qualcomm has been waiting until this year. It was in 1985 that Dr. Owen Jacob convened six other visionaries to co-found.

And Li Xuan had already started poaching people two years ago. Among all seven founders, the most important are undoubtedly Jacob, known as the "Godfather of Qualcomm", and Professor Andrew Witterby, Chief Scientist of Qualcomm.

Li Xuan never considered poaching Owen Jacob, the core founder of Qualcomm's entrepreneurial team, to the Eastern Group. Because this person is a famous dictator and tyrant in the American IT industry in later generations. And this kind of person often has a strong desire to control. I would never want to be under someone else for long.

Later, when Jacob retired, he directly appointed his son to replace him in charge of Qualcomm. This is definitely a very rare thing in the US IT industry. It caused an uproar in public opinion back then. It can also be seen that Jacob's control over Qualcomm has reached a point where it is beyond limit.

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

So old Jacob's talent is undoubted, but he is only suitable for himself to be the boss, so that others will obey his orders unconditionally. And it is enough for the Eastern Bloc to have Li Xuan, a person who can call the shots, so the target he chose to attack was another Professor Andrew Viterbi.

Two years ago, the Institute of Oriental Studies offered Professor Andrew Wittby a generous package that he could not refuse, and recruited him from the University of California, San Diego to the Institute of Oriental Studies' R&D center in Silicon Valley.

As the saying goes, interlacing is like separating mountains, Li Xuan was engaged in the field of chip design in his previous life, and his understanding of wireless communication technology was very limited, so he naturally couldn't open his golden finger as much as he did in the semiconductor field. He decided to know TDMA (time division multiple access), CDMA (code division multiple access) and other terms.

The so-called Code Multiple Divided Access (CDMA) refers to the signals used by different users to transmit information, not by different frequencies or time slots, but by different coding sequences.

Li Xuan can only provide such a concept, but for a real expert, it is actually enough to have such a research idea. Specifically, how to use coding to distinguish between them requires R&D personnel to experiment again and again to explore.

The rest of Li Xuan's work only needs to provide sufficient R&D funds for Professor Viterbi's CDMA project team. Since its establishment, the CDMA project team has been one of the highest priority projects within the Oriental Institute.

After Liu Wei joined 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. He has just completed a technology research and development that solves a key difficulty in CDMA technology and takes it a small step closer to finally putting it into 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 the focuses of his attention, so he has a lot of impressions of the name Liu Wei.

After Li Xuan talked to the three employees for a while, he turned around and walked towards the corner where Zhong Chuhong was, while the three people behind him fell into a huge surprise.

"Liu Wei, you kid is really hidden!Fang Qianqian, after you go back, quickly relay Li Sheng's evaluation just now to your father, and see if he will continue to oppose your relationship with Liu Wei!" Liu Chang stretched out his hand and hammered his friend hard.

The Oriental Group has expanded to more than 50,000 employees. It is definitely a very proud thing to let Li Sheng, who has a lot of opportunities, remember your name from so many people!

Liu Wei smiled, but the excitement in his eyes couldn't be hidden. And Fang Qianqian looked at her boyfriend with a little obsession, she was proud that she didn't choose the wrong person.

As Liu Chang joked just now, with Li Sheng's importance to her boyfriend, Fang Qianqian also felt relieved. Li Sheng's golden words were enough to offset the resistance from her family.

Who is Li Xuan, he is the well-known "God of Wealth Lee"! No one should doubt the vision of "God of Wealth Lee"! This is already the consensus of all investors in Hong Kong!

Fang Qianqian's father is actually a very realistic businessman. Recently, he has no longer explicitly objected to his daughter's relationship with Liu Wei, a mainland boy. Because Liu Wei is showing his great value.

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

"Li Sheng just said that he will pay for today's consumption! Let's take advantage of Li Sheng's failure to settle the bill and leave, hurry up and pick a bottle of the most expensive wine here to celebrate!" Liu Chang said with a smile.

Since the two were selected to come to Hong Kong to participate in the "Dongfanghong" exchange program a few years ago, he and Liu Wei have formed a deep friendship. Although he now has a little jealousy in his heart, the kid next to him has a bumper harvest in love and career, 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.

"A few employees of the company, don't care about this kind of minutiae! I just showed my face on stage to sing and express my heart, shouldn't you be moved now!" Li Xuan saw that she didn't grasp the point, and deliberately made a very depressed expression.

"I was touched just now, but who made it take you so long to come back. The mood of emotion has calmed down!" Zhong Chuhong showed a sly smile on his face.

"Do you think I should just get rid of these three guys who ruined the romantic atmosphere!" Liu Xuan squinted his eyes and glanced in the direction of Liu Wei and the others, and said angrily.

"I don't think I've heard this song "Two Butterflies" before?" Zhong Chuhong asked with a smile.

"Authentic and original, today is the first time this song has come out! Don't you think your husband is full of sincerity!" Li Xuan said with a slight expression. (To be continued......)
