The Science Fiction World of Xueba

After roughly explaining the development of 2G/3G/4G/5G in the future, Pang Xuelin said: "These are my personal opinions on the upgrading of mobile communication technology. Do you have any questions?"

Ren Zhengfei and Zheng Baoyong glanced at each other.

Ren Zhengfei smiled and said, "President Pang, if we want to get involved in the mobile communication market, where do you think we should start?"

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

Although Pang Xuelin said he would not participate in Huawei's management, everyone knew that Pang Xuelin had to make a single decision on Huawei's future development direction.

Of course, they also want to hear Pang Xuelin's thoughts. After all, this young genius has shown too many things beyond ordinary people before.

Pang Xuelin pondered for a moment and said: "If a communication company is compared to an army, products are weapons, the basis of an army's combat effectiveness, and the basis of a company's competitiveness. As a technology-based company, products are our core. At present, we The main business of Huawei is in the field of program-controlled switches, but in the foreseeable ten years, the market of program-controlled switches will gradually shrink, and the era of mobile communication is coming. At that time, the competitiveness of wireless products will be the basis for us to conquer the city of Warwick. I hope everyone remembers that No matter how high a company's engineering management level, sales ability, or marketing level, it must rely on competitive products to open up the market and survive. If there is no competitive product, superb sales Ability and marketing level can only delay his decline, but will not change its downward trend..."

"Our country started the construction of mobile communication network in 1987. In the first half of this year, the Ministry of Posts and Telecommunications established the Mobile Communication Bureau, and on the 19th of last month, China Unicom was established in Beijing. I personally expect that by this time next year, GSM The digital telephone network will be officially launched, and the next generation of 2G mobile phones based on the GSM/CDMA network will appear soon, 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 country separated the paging business of telecommunications in 1994 and established China Unicom.

China Unicom used the GSM network, and at that time China Telecom was still waiting for the commercial use of Motorola's CDMA system. At that time, Motorola had an unusual relationship with China Telecom because of its paging and analog systems.

However, because China Unicom's GSM was quickly released for use, and it was much better than China Telecom's analog mobile network, China Telecom didn't have the patience to wait, and soon got on GSM.

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

Only then did the three major operators of China Mobile, China Telecom and China Unicom come into being.

Pang Xuelin paused, and continued: "So, next, we must start to build our own GSM products. As we all know, the mobile communication system is mainly composed of mobile stations, base station subsystems and network subsystems. The most suitable for us to enter The place is the base station subsystem. The base station subsystem consists of a base transceiver station (BTS) and a base station controller (BSC). A complete BTS includes wireless transmitting/receiving equipment, antennas and all wireless interface-specific signal processing parts. BTS can As a wireless modem, it is responsible for receiving and sending processing of mobile signals. Generally, in a certain area, multiple sub-base stations and transceiver stations form a cellular network with each other. By controlling the signal exchange between transceiver stations and transceiver stations Transmission and reception to achieve the transmission of mobile communication signals.The base station controller (BSC) is the connection point between the base transceiver station and the mobile switching center, and also the connection point between the base transceiver station (BTS) and the mobile switching center (MSC). Provide an interface for exchanging information between. A base station controller usually controls several base transceiver stations, and its main function is to manage wireless channels, implement call and communication link establishment and tear down, and provide handover for mobile stations in the control area Control, etc., so the next two major products of our operator business are base transceiver stations and base station controllers..."

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

According to Pang Xuelin's opinion, Warwick's engineering research and development department is divided into two parts, one is the operator business department, and the other is the consumer electronics business department.

The operator 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 mobile phone business.

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

In the next month, Pang Xuelin seemed to have returned to the scene when he helped Huawei's R\u0026D department develop a program-controlled switch last year, and began to explain to Huawei's R\u0026D personnel the direction of product development related to the operator's business.

These engineering problems are not too difficult for Pang Xuelin. He only needs to break down the products that have appeared in the real Huawei, one by one, and explain them to everyone.

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

From Huawei's earliest BTS1.0, to BTS2.0, and then to BTS3.0, how to iterate 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 not only technical aspects.

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

However, China Mobile still wanted to cover rural areas, and it hadn't been long before China Mobile separated, and the core of the network was still in cities.

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

So Huawei developed a marginal network small base station, which is directly hung on a utility pole, and an omnidirectional antenna is installed. No backup power is required. The base station is directly equipped with an optical interface board, as long as the transmission is pulled.

Historically, Huawei relied on the small base stations of the marginal network to deploy many points across the country.

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

Even because the "marginal network" was packaged so successfully that Warwick wanted to enter the city after 2005, and specially repackaged the macro base station to avoid the influence of "Huawei = marginal network".

Of course, these are things for later.

Historically, Huawei's early BTS devices were copycat products imitating foreign manufacturers.

Before 2001, Huawei's research and development may have the same understanding of other big-name competitors, such as Ericsson, Moto, and Nokia; The carrier frequency of the company is more, and some markets are smaller, but at that time, the competitors were already viewed 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 Huawei's most classic BTS312 base transceiver station, and then arranged the research and development tasks according to the modularization.

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

Pang Xuelin also took out the most classic BCS32 among the BSC platforms in the history of Huawei. It is a single module, which can be done in one cabinet and supports 128TRX.

Although it is small, it has a high degree of integration. One cabinet handles the main control, base station interface, A interface transmission board, TC code conversion unit, etc.

These platforms are basically improved designs by Pang Xuelin, with good scalability and versatility.

In the future, if you want to continue to improve on this basis, you only need to slightly modify the hardware architecture. Supporting 10,000 carrier frequencies is not an unreachable 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 Huawei's first mobile phone.

In the real world, Nokia 1100 is a practical and low-cost candy bar mobile phone with a cumulative global sales volume of more than 200 million units, which can be said to be an unprecedented masterpiece.

Historically, Huawei relied on the small base stations of the marginal network to deploy many points across the country.

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

Even because the "marginal network" was packaged so successfully that Warwick wanted to enter the city after 2005, and specially repackaged the macro base station to avoid the influence of "Huawei = marginal network".

...

Time unknowingly entered September.

During this month, Pang Xuelin not only completed the training of all R\u0026D personnel of Huawei R\u0026D Department, but also successfully completed the capital injection to Huawei.

After the cash of 2.5 billion arrived in the account, Warwick became rich and powerful in an instant.

At Pang Xuelin's request, Ren Zhengfei began to attack everywhere to find the talents he needed for Pang Xuelin.

And Warwick's R\u0026D department is also expanding at a high speed at the speed of blowing a balloon.

But all this is not a bad thing for Huawei, which is in urgent need of talents.

Zheng Baoyong, Xu Wenwei and the others recorded all the content of Pang Xuelin's lectures for everyone in the past month.

There are many technical points that need to be digested by talents.

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

With so many people coming all at once, this will pose a strong challenge to Huawei's subsequent management, but Pang Xuelin is not very worried.

The management can be left to Ren Zhengfei. This boss has already proven his management ability in the real world. It may not be a good thing to intervene by himself.

In the evening, after completing the last moment in Huawei's R\u0026D department, Pang Xuelin smelled a strong fragrance as soon as he returned home.

"Qingqing, what's delicious tonight?"

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

In the past month, Pang Xuelin has gotten used to living with Mu Qingqing.

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

Even Ren Zhengfei sometimes subtly persuaded Pang Xuelin not to let down such a girl who was so sincere to him.

Regarding this, Pang Xuelin felt helpless while being dumbfounded.

I can only fool it by thinking that I am still young and I am not going to fall in love for the time being.

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

"Brother Pang Pang, wash your hands quickly. Tonight, I made pork belly chicken and various shabu-shabu dishes. 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 too spicy, so he has never been used to Cantonese cuisine.

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

Soon, Mu Qingqing brought the casserole with pork belly and chicken to the dining table, and the two of them worked together to make various dishes. 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 have cold beer to eat it.

"Brother Pang, pour me some too."

Holding a transparent glass, Mu Qingqing said to Pang Xuelin.

Pang Xuelin was slightly taken aback, 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, why don't you have a drink with me!"

"Oh well!"

Pang Xuelin hesitated for a moment, but poured it all for Mu Qingqing.
