Roughly explained the development of the next 2G/3G/4G/5G, Pang Xuelin said: "These are my personal views on the upgrading of mobile communication technology, do you have any questions? ”

Ren Zhengfei and Zheng Bao glanced at them.

Ren Zhengfei said with a smile: "Mr. Pang, if we want to get involved in the mobile communication market next, where do you think we should start?" ”

Everyone in the conference room once again focused on Pang Xuelin.

Although Pang Xuelin said that he would not participate in the management of Warwick, everyone understands that the next development direction of Warwick must be decided by Pang Xuelin.

Of course, they also wanted to hear Pang Xuelin's thoughts, after all, this genius boy had already shown too many things beyond ordinary people before.

Pang Xuelin pondered for a moment and said: "If the communication enterprise is compared to the army, the product is the weapon, the basis of the combat effectiveness of an army, that is, the foundation of a company's competitiveness. As a technology-based company, our products are at the heart of who we are. At present, our main business is in the field of program-controlled switches, but in the foreseeable ten years, the program-controlled switch market will gradually shrink, and the era of mobile communication is coming. At that time, the competitiveness of wireless products is the foundation of our Warwick conquering the city. I hope you will remember that no matter how high the engineering management level, how high the sales ability, and how high the marketing level of a company, it must rely on competitive products in order to open the market and survive. If there is no competitive product, superb sales ability and marketing level, it can only slow down his downward trend, but will not change its downward trend......"

"Our country began the construction of mobile communication network in 1987, in the first half of this year, the Ministry of Posts and Telecommunications set up a mobile communications bureau, and on the 19th of last month, China Unicom was established in Beijing, I personally expect that this time next year, the GSM digital telephone network will be officially opened, the next generation of 2G mobile phones based on GSM/CDMA network will soon appear, so there is not much time left for us."

In the history of the real world, in order to break the monopoly of telecommunications, the state established China Unicom in 1994 by separating the paging business of telecommunications.

China Unicom applied the GSM network, and at that time, China Telecom was still waiting for Motorola's CDMA system to be commercialized.

However, because Unicom's GSM was quickly put into use, and it was much better than Telecom's analog mobile network, Telecom did not have the patience to wait, and soon got on GSM.

Then in 1998, the state cut China Telecom again, separated the mobile communication business, and established China Mobile.

This is the three-legged pattern of the three major operators of China Mobile, China Telecom and China Unicom in the future.

Pang Xuelin paused and continued: "So, next, we have to start building our own GSM products. As we all know, the mobile communication system is mainly composed of a mobile station, a base station subsystem and a network subsystem. The most suitable place for us to cut into is the base station subsystem, which is composed of a base station transceiver station (BTS) and a base station controller (BSC). A complete BTS includes wireless transmit/receive equipment, antennas, and signal processing parts specific to all wireless interfaces. BTS can be thought of as a wireless modem that is responsible for the reception and transmission processing of mobile signals. In general, in a certain area, a plurality of sub-base stations and transceivers form a cellular network with each other, and the transmission of mobile communication signals is achieved by controlling the mutual transmission and reception of signals between transceivers and transceivers. The base station controller (BSC) is the connection point between the base transceiver station and the mobile switching center, and also provides an interface for the exchange of information between the base transceiver station (BTS) and the mobile switching center (MSC). A base station controller usually controls several base station transceiver stations, and its main functions are to carry out wireless channel management, implement the establishment and removal of calls and communication links, and control the cross-area handover of mobile stations in the control area, etc., so the next two main products of our operator business are base station transceiver stations and base station controllers......"

[Shulian xs.xyz]......

It took a whole day for Pang Xuelin to unify the opinions of Huawei management and determine the direction of research and development of new products.

According to Pang Xuelin's opinion, Warwick's engineering R&D department is divided into two parts, one is the operator division and the other is the consumer electronics division.

The carrier business is mainly responsible for the research and development of base stations and related equipment, while the consumer electronics business is mainly responsible for the research and development of the mobile phone business.

Although the general direction of research and development has been determined, it does not mean that everything is fine.

In the next month, Pang Xuelin seemed to return to the scene when he helped Warwick's R&D department develop program-controlled switches last year, and began to explain the R&D direction of relevant products for the operator's business to Warwick's R&D personnel.

These engineering problems are not very difficult for Pang Xuelin, he only needs to break the products that have appeared in reality and explain them to everyone.

For example, Pang Xuelin explained BTS products to everyone, and he had to start with the baseband board, TRX unit, power amplifier unit, splitter and duplexer unit.

From Warwick's earliest BTS1.0, to BTS2.0, and then to BTS3.0, how to iterate with each other step by step, such as how to integrate the power amplifier and TRX, so as to avoid many complicated cable connections and so on.

Of course, Pang Xuelin needs to consider more than just technical content.

For example, in another four or five years, although the mobile phone penetration rate of young people in the cities was already relatively high, the mobile phone penetration rate was not very high in the rural areas of the central and western regions and the relatively backward rural areas in the east.

However, China Mobile still had to cover rural areas, and at that time, China Mobile had not been separated for a long time, and the core of the network was still in the city.

If you build a base station in the real sense, including computer room, tower, backup power, etc., the cost is very high.

So Huawei has developed a kind of marginal network small base station, which is directly hung on a telephone pole and set up an omnidirectional antenna, without power backup, and the base station is directly equipped with an optical interface board, as long as the transmission is pulled.

Historically, Warwick is a small base station that relies on the marginal network, and it has been distributed in many points across the country.

Since it is difficult to relocate the base station after the deployment, Huawei has gradually opened up the domestic market through the entry of small base stations.

Even because the "marginal network" was packaged too successfully, Warwick wanted to enter the city after 05 years, and specially repackaged the macro base station to avoid the impact of "Huawei = marginal network".

Of course, that's all for later.

Historically, Warwick's early BTS equipment was an imitation of copycat products from foreign manufacturers.

Before 01 year, Huawei's R&D may have a similar understanding of other big-name friends, such as Ericsson, Moto, and Nokia; Other friends, such as Siemens, Nortel, Lucent, etc., because of the early and late entry time, some have more carrier frequencies in the network, and some have smaller markets, but at that time, they were already looking at friends according to the above two groups.

However, in this era, Pang Xuelin naturally does not need to imitate, he directly gave the design framework of Warwick's most classic BTS312 base station transceiver station, and then arranged the research and development tasks according to modularity.

After completing the layout of BTS products, Pang Xuelin started the layout of BSC products.

Pang Xuelin also took out the most classic BCS32 of the BSC platform in the history of Warwick, which is single-module, can be done in one cabinet, and supports 128TRX.

Don't look small, but the integration is very high, one cabinet can handle the main control, base station interface, A interface transmission board, TC code conversion unit, etc.

These platforms are basically designed after Pang Xuelin's improvement, with good scalability and versatility.

If you want to continue to improve on this basis in the future, you only need to slightly modify the hardware architecture, and supporting 10,000 carrier frequency is not an unattainable goal, it is nothing more than adding a few more modules.

As for the consumer electronics business, Pang Xuelin directly used the Nokia 1100 as a template as Warwick's first mobile phone.

In the real world, the Nokia 1100 focuses on practical and low-cost straight phones, and has sold more than 200 million units worldwide, which can be said to be an unprecedented masterpiece.

Historically, Warwick is a small base station that relies on the marginal network, and it has been distributed in many points across the country.

Since it is difficult to relocate the base station after the deployment, Huawei has gradually opened up the domestic market through the entry of small base stations.

Even because the "marginal network" was packaged too successfully, Warwick wanted to enter the city after 05 years, and specially repackaged the macro base station to avoid the impact of "Huawei = marginal network".

……

The time imperceptibly entered September.

In this month, Pang Xuelin not only completed the training of all R&D personnel of Huawei R&D Department, but also successfully completed the capital injection of Warwick.

After the cash of 2.5 billion yuan arrived, Warwick instantly became wealthy.

At the request of Pang Xuelin, Ren Zhengfei began to attack everywhere to tap the talents needed for Pang Xuelin.

Warwick's R&D department is also expanding at a high speed at a balloon speed.

However, all this is not a bad thing for Warwick, which is in dire need of talent.

The content of Pang Xuelin's lectures in the past month has been recorded by Zheng Baoyong and Xu Wenwei one by one.

There are a lot of technical points that need to be digested by talent.

At present, the total number of employees of Huawei is less than 500, and according to Pang Xuelin's plan, in the next six months, Huawei will recruit more than 1,000 engineers.

With so many people coming at once, this will pose a strong challenge to Warwick's next management, but Pang Xuelin is not too worried.

Just leave the management to Ren Zhengfei, this big guy has already proven his management ability in the real world, and it is not necessarily a good thing to get involved by himself.

In the evening, after completing the last moment in the R&D department of Warwick, Pang Xuelin just returned home and smelled a strong fragrance.

"Qingqing, what do you want to eat at night?"

As soon as Pang Xuelin came to the kitchen door, he saw Mu Qingqing busy in front of the stove.

In the past month, Pang Xuelin has become accustomed to living with Mu Qingqing.

Every day when he goes to work in Warwick, Mu Qingqing will try his best to cook all kinds of food for him, and even take the initiative to send it to Warwick at noon, which has almost become a beautiful scenery of Warwick.

Even Ren Zhengfei sometimes vaguely persuaded Pang Xuelin not to live up to such a girl who was sincere to him.

In this regard, Pang Xuelin couldn't laugh or cry at the same time, but also a little helpless.

can only fool me by saying that he is still young and is not ready to fall in love for the time being.

Mu Qingqing raised her head and saw Pang Xuelin, the girl's mouth was slightly upturned, revealing two beautiful mazes.

"Brother Pang, go wash your hands, I made pork belly chicken at night, and all kinds of shabu-shabu, we can just eat pork belly chicken hot pot."

"Pork belly chicken?"

Pang Xuelin's eyes lit up.

Although he is from Jiangsu and Zhejiang, his taste is spicy, so he has not been very suitable for Cantonese cuisine.

Only this pork belly chicken is his favorite dish among many Cantonese dishes.

Soon, Mu Qingqing brought the casserole with pork belly chicken to the table, and the two worked together to make all kinds of shabu-shabu, and Pang Xuelin also took out a few bottles of beer from the refrigerator.

To eat pork belly chicken hot pot in this weather, you must eat it with cold beer.

"Brother Pang, pour me some too."

Mu Qingqing held the transparent glass and said to Pang Xuelin.

Pang Xuelin was slightly stunned and said, "Qingqing, can't you drink?" ”

Mu Qingqing pursed her lips and smiled: "Isn't this going back to Lancheng tomorrow?" I'm afraid we won't see each other for a long time, Brother Pang, you can have a drink with me! ”

"That'...... All right! ”

Pang Xuelin hesitated, but poured all of them for Mu Qingqing.
