Li Sheng, a digital mobile phone that can realize basic functions such as making calls and receiving text messages, usually consists of five parts. 『』『』?e novel?? The five parts of ww?w?.?1xiaoshuo are the radio frequency part, the baseband part, the power management part, the peripherals, and the software.

The radio frequency part is responsible for sending and receiving the number of messages, and its quality directly determines the call quality of the mobile phone. Motorola's Big Brother is able to beat other brands because its RF system is so good that it can maintain call quality in places where other mobile phones can't receive signals.

The role of the power management part should not be underestimated, because the power of the mobile phone battery is very limited, so the power management level directly determines the standby time of the mobile phone. If the standby time of the phone is too short, then even if its functions are excellent, the practical application value will be greatly reduced!

The core of these two parts is naturally RF chips and power supply chips. The 88 digital mobile phones we launched this time use RF chips and power chips provided by Fairchild Semiconductor. Liu Yu, the person in charge of the entire mobile communication project team of the Oriental Research Institute, was accompanying Li Xuan to explain to him in detail.

Hong Kong Telecom has already started the trial operation of the digital mobile phone network, and Li Xuan naturally wants to take a serious look at the exhibition status of the mobile communications business of the Oriental Group. The Oriental Research Institute is the leader of the entire digital mobile phone project research plan, so Li Xuan naturally chose to come here to understand the situation.

On the other side of Tai Po Road, Sha Tin, Hong Kong, across the road from the Chinese University of Hong Kong, the research building of the Institute of Oriental Studies has been continuously expanded and increased to eight. In addition, the Hong Kong government has circled a large area around the Hong Kong Research Centre of the Institute of Oriental Studies and established the Sha Tin Science and Technology Park.

To this end, the Hong Kong government has set up the management of the Hong Kong Science and Technology Park under the Economic Department, which is responsible for the unified management and operation of the Sha Tin Science and Technology Park, as well as the Fotan Industrial Park, which has gradually become a high-tech electronics industry cluster, and the electronics industrial park in Tin Shui Wai.

In another time and space, Sha Tin is one of the largest satellite towns in Hong Kong outside of Hong Kong Island and Kowloon City. Its main role is to share the increasingly unbearable demographic pressure on the urban areas of Hong Kong and Kowloon. Even in the XXI century. Except for a racecourse, Sha Tin is still lackluster in other aspects.

At this time and space, due to the emergence of the butterfly of the Eastern Group, Sha Tin seems to have begun to have a trend of exhibition to the high-tech industry cluster. Fotan Industrial Park has become Asia's most famous micro-business incubator and venture capital hub.

The original horse feed water. It is also the location of CUHK, and because of the establishment and expansion of the Hong Kong Research Center of the Institute of Oriental Studies, it has become a scientific research mecca for many technicians throughout Asia. It is here that many Ming, who have been born or are giving birth to many influences on the entire human race. For example, the world's most widely used processor chip, ER, came out here.

The world's first commercial digital mobile phone, 88, was also born in the Oriental Real Yàn Building next to Tai Po Highway in Ma Liu Shui. The process of turning on the mobile phone is a huge system project. The Oriental Group has been able to proudly announce that it has been able to support such an epoch-making project.

For example, RF chips and power chips are provided by other Fairchild companies in charge of the analog semiconductor business of the Oriental Group. The system software of the mobile phone is opened by Dongfang System Software Company. The peripheral parts of the mobile phone, such as the S black and white LCD screen, are manufactured by the peripheral company Xincai Optoelectronics.

"The baseband part is the core part of the whole mobile phone, and the entire baseband system is composed of a central processing unit, a digital signal processor, and channel encoders, modems and interface modules.

On the 88, the modules of the baseband part are still independent and scattered, but we have begun the integration of the baseband chip. It is hoped that they can be integrated into an S chip, thereby reducing the overall design difficulty of the mobile phone. Liu Yu pointed to the mobile phone motherboard that had just been unlocked, and introduced the role of each key chip to Li Xuan one by one.

The "88" refers to "bi1e (mobile phone)" and "88" refers to 1988. The PU (central processing unit) in the baseband system of the 88 mobile phone is the treasure of the Eastern Group, and the AR structure in another time and space is relying on the mobile phone industry to turn over and become a processor architecture that can be as famous as the X86 series of Intel Corporation.

The DSP (digital processor) in the 88 baseband system is also a technology acquired from Texas Instruments at a great cost under Li Xuan's leadership. After the mobile phone industry begins to explode, Deyi Company estimates that even the intestines will regret it.

On the bright side, Li Xuan's research on this 88 digital mobile phone. It doesn't seem to be personally involved, but in fact, every step of it is under Li Xuan's control. Whether it is the basic communication technology - D, or the specific design and layout of mobile phones, Li Xuan has made a good plan behind the scenes.

Listen to Liu Yu's introduction beside him. Li Xuan kept nodding. He pointed out that the general direction of research can only make the people below take fewer detours, but every scientific research achievement still requires researchers to spend countless wisdom to explore. Hundreds or thousands of scientific research achievements are gathered together to create a practical scientific and technological product.

Li Xuan previously saw an internal audit report of the group, and the total investment of the Oriental Group in the field of mobile communications over the years has approached 1o billion US dollars. This is by no means a small amount, but Li Xuan feels that it is very worthwhile.

Because the benefits of the Eastern Group are not just the 88 mobile phone. With the transformation of mobile communication from the analog era to the digital age. The Eastern Bloc has taken the lead in the industry as a whole.

For example, with the help of Nordic analog cellular systems, Sweden's Ericsson began to enter the emerging mobile communication equipment market. With the G** digital cellular system in Europe, Ericsson has rapidly grown into the world's largest supplier of mobile communication equipment.

The Eastern Group also launched a layout in the field of communication equipment from the beginning. For example, the DS series digital program-controlled telephone exchange, which was produced in cooperation with China, has been continuously conquering the domestic market in recent years, and has almost completely squeezed other competitors out of the Chinese market.

The telecommunications equipment market is a relatively high monopoly field, and it is not easy for the Eastern Group to defeat the established European and American enterprises in the traditional telephone exchange and other markets. In the emerging field of mobile communication equipment, everyone is back on the same track.

Moreover, the Eastern Bloc now has a huge advantage, that is, compared with the G** technology that Europe is developing, it has achieved commercialization ahead of schedule. According to the intelligence that Oriental Commercial has spied on in Europe, it will take at least one to two years for G** to reach technical maturity.

And before the advent of D technology, it can show the world its excellent performance. Undoubtedly, we can get a more favorable advantage in the standard competition in the next 2G era.

Li Sheng, compared with traditional analog mobile phones, digital mobile phones have not only made a leap forward in call quality and call confidentiality. It is also more abundant in mobile phone functions. For example, our 88 has features such as caller ID, voicemail, and text messages that Big Brother does not have!

In particular, text messages, i.e., receiving text messages, can greatly reduce the frequency of calls made by users. Those concise and non-essential exchanges can be communicated by text message, which greatly reduces the cost of call bills!" Liu Yu began to introduce the advantages of digital mobile phones.

Li Xuan, as a person who has come over, is naturally clear about this. SMS is one of the most important features in the 2G era. Especially in countries like China, the frequency of SMS usage is much higher than in Europe and the United States due to the high pricing of mobile phone call tariffs in the early days.

Previously, at Hong Kong Telecom, Li Xuan, like the company's president, Gu Xinping, emphasized the new technology of SMS. SMS can become an important breakthrough for operators to promote the low tariff of digital mobile phones, a text message charges o.1 Hong Kong dollars, far cheaper than making a call, everyone can afford it!

In addition to SMS, another important innovation in the 2G era is the beginning of the mobile Internet. Of course, the 88 in front of Li Xuan also has the function of surfing the Internet, but the important role of the mobile Internet. In the future, even the basic phone calling function has long passed. Therefore, mobile networking technology will be another research focus of the Oriental Research Institute in the field of mobile communications.

After all, a person's energy is limited, for example, Li Xuan now has to spend time managing a multinational group with a total of tens of thousands of employees, and he has to maneuver between several women, pay attention to the growth of his family and children, and naturally have very little time left to personally participate in scientific research. It's been a long time since he's been in the real room for several days like he did at the beginning, and now even when he comes to the research center here in Shatin, he goes around occasionally.

The same is true for a company and a project, and the mobile communication development team can be called one of the largest teams under the Oriental Research Institute. and participate in the research of basic communication equipment, participate in the development of underlying communication technology, and also participate in the realization of specific mobile phone functions.

This kind of large and comprehensive structure, if it weren't for Li Xuan's rebirth golden finger. Pointing out clear ideas to all aspects will inevitably lead to a decrease in efficiency. Everyone is a swarm of headless flies, and we don't know which areas are the priorities.

Therefore, after the phased results of the mobile communication project, Li Xuan felt that it was necessary to carry out a split, just like the previous LCD project. It's just that compared with the previous LCD project, which was completely split into independent subsidiaries, the mobile communication project is larger. It's also more complicated. According to Li Xuan's plan, the research of the underlying basic technology of the project team will still be retained in the Oriental Research Institute, and the D (code division multiple access) communication technology will be cooperated with the outside world in the form of patent authorization in the future.

As for those research institutes at the application level, they were all independently split into a new subsidiary. Li Xuan has even thought of the name of the new company, which is called Huaxing Mobile Communication Technology Company. Later, there were two very famous communication equipment manufacturers in China, and Li Xuan simply took one of the two companies.

Huaxing, well, this name sounds a little earthy, but who called him such a bad taste! Huaxing Company, which was spun off from the Oriental Research Institute, is mainly responsible for the research and manufacture of mobile phones and mobile communication equipment.

※※※※※※※※※※※※※※※※※※※※

"Qianqian, do you think I should continue to stay in the Oriental Research Institute, or transfer to the newly established Huaxing Technology?" Liu Wei sat on the sand with a sad face, and asked his wife with some distress.

Since Li Xuan had a plan in mind, he naturally began to make specific moves soon. This is the advantage of a private company, the Oriental Research Institute is not listed, and Li Xuan, the boss, does not need to be approved by an institution such as the board of directors.

Of course, before this, he must still have to communicate with the top executives of the Eastern Group in advance, after all, the specific things still have to be done by the people below. There was nothing wrong with his thinking, so naturally there was no opposition within the group.

As one of the first batch of fresh graduates recruited by the Institute of Oriental Studies in China, Liu Wei joined the Institute of Oriental Studies after graduating from Tsinghua University and was arranged to work in the Center for Deep-Sea Studies. He majored in communication engineering in college, and he was placed in the D technical group from the beginning and contributed a lot of achievements.
