MTL - The Science Fiction World of Xueba-Chapter 471 product line

Probably explaining the development status 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 with each other.

Ren Zhengfei said with a smile: "President Zong, if we are going to intervene in the mobile communication market next, where do you think we should start?"

Everyone in the conference room focused on Pang Xuelin again.

Although Pang Xuelin said that he would not participate in the management of Warwick, everyone knew that the future direction of Warwick must still be decided by Pang Xuelin.

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

Pang Xuelin pondered for a moment, and said: "If you compare a communications company to an army, the product is a weapon, which is the basis of an army's combat effectiveness, and the foundation of a company's competitiveness. As a technological company, the product is our core. At present, we The main business 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 communications is coming. At that time, the competitiveness of wireless products will be the foundation of our war strategy. I hope everyone remember, No matter how high the level of engineering management, high sales ability, and high level of marketing, a company must rely on competitive products to open the market and survive. If there is no competitive product, superb sales Ability and marketing level can only delay his decline, and it will not change its downward trend ... "

"Our country started the construction of a mobile communications network in 1987. In the first half of this year, the Ministry of Posts and Telecommunications established a mobile communications bureau. On the 19th of last month, China Unicom was established in Beijing. I personally expect that this time next year, GSM The digital telephone network will be officially opened, and the next generation of 2G mobile phones based on GSM / CDMA networks will soon appear, so we have little time left. "

In the history of the real world, in order to break the monopoly of telecommunications, the country established China Unicom in 1994 to separate out the paging service of telecommunications.

China Unicom applied the GSM network. At that time, China Telecom was still waiting hard for Motorola's CDMA system to be commercialized. At that time, Motorola had a special relationship with telecommunications because of the paging and analog systems.

However, because China Unicom GSM will soon use the number, and it is much better than Telecom's analog mobile network, so Telecom has no patience to wait, and soon went to GSM.

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

This is where the three major operators of mobile, telecommunications, and China Unicom stand out.

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. And the most suitable for us to enter The place is the base station subsystem. The base station subsystem is composed of a base transceiver station (BTS) and a base station controller (BSC). A complete BTS includes wireless transmission / reception equipment, antennas, and signal processing parts unique to all wireless interfaces. BTS can Seen as a wireless modem, it is responsible for the reception and transmission 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 between the transceiver station and the transceiver station. Transmit and receive 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. It is also the base station transceiver station (BTS) and the mobile switching center (MSC). Provides an interface for exchanging information. A base station controller usually controls several base transceiver stations. The main functions are to perform wireless channel management, to establish and remove call and communication links, and to control the handover of mobile stations in this control area, so the next two main products of our operator business are base stations. Transceiver and base station controller ... "

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

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

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

Although the general R & D direction is determined, this does not mean that everything will be fine.

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

These problems in engineering are not difficult for Pang Xuelin. He only needs to break the products that once appeared in Zhonghuawei to explain to everyone.

For example, Pang Xuelin explained the BTS product to everyone, so 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 step by step with each other, 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 the next four to five years, although the mobile phone penetration rate of young people in the city is already relatively high, the mobile phone penetration rate was not very high in rural areas in the central and western regions and relatively backward rural areas in the east.

But China Mobile still has to cover rural areas, and it didn't take long for mobile to separate, and the core of the network was still in the city.

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 Warwick developed a small base station for the marginal network, which was hung directly on a telephone pole and set up an omnidirectional antenna. There is no need to prepare electricity. The base station directly carries an optical interface board, as long as the transmission is pulled.

Historically, Warwick was a small base station that relied on the marginal network, and it has deployed many points across the country.

Because it is difficult to relocate after the base station is deployed, Huawei gradually opened the domestic market through the entry of small base stations.

Even because the "marginal network" was packaged too successfully, it led Warwick to enter the city after 2005, and specially packaged the macro base station to avoid the influence of "Huawei = marginal network".

Of course, these are all afterwords.

Historically, the early BTS equipment of Warwick was a copycat product imitating foreign manufacturers.

Before 01, Huawei R & D may have similar understanding of other big-name friends, such as Ericsson, Moto, Nokia; other friends, such as Siemens, Nortel, Lucent, etc. Because of the early and late time of entry, some are online. The carrier frequency is higher, and some markets are smaller, but at that time, it was already based on the above two groups to treat friends.

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 transceiver station, and then arranged the R & D tasks according to the 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 in the BSC platform in the history of Warwick, single module, one cabinet, and support 128TRX.

Don't look small, but the degree of integration is very high, a cabinet to get 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 to support the 10,000 carrier frequency is not an unreachable goal, nothing more than add a few more modules.

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

In the real world, the Nokia 1100's global sales volume of practical and low-cost candy bar phones has exceeded 200 million units, which can be said to be an unprecedented masterpiece.

Historically, Warwick was a small base station that relied on the marginal network, and it has deployed many points across the country.

Because it is difficult to relocate after the base station is deployed, Huawei gradually opened the domestic market through the entry of small base stations.

Even because the "marginal network" was packaged too successfully, it led Warwick to enter the city after 2005, and specially packaged the macro base station to avoid the influence of "Huawei = marginal network".

...

Time unknowingly enters September.

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

After 2.5 billion in cash arrived, Warwick instantly became wealthy.

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

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

But all this is not a bad thing for Warwick, who desperately needs talent.

The contents of Pang Xuelin's class for everyone this month have been recorded by Zheng Baoyong and Xu Wenwei.

There are many technical points that require talent to digest.

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

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

It is enough for Ren Zhengfei to manage the matter. This big brother has already proven his management ability in the real world. It is not necessarily a good thing to intervene in it.

On the evening of that day, after finishing the last moment in the research and development department of Warwick, Pang Xuelin had just returned home and smelled a strong fragrance.

"Qingqing, what's delicious at night?"

Pang Xuelin just came to the kitchen door and saw Mu Qingqing busy in front of the stove.

This month, Pang Xuelin has been used to living with Mu Qingqing.

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

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

In response to this, Pang Xuelin couldn't help crying and laughing, but was somewhat helpless.

I can only use my young age and not ready to fall in love for the time being.

Mu Qingqing looked up and saw Pang Xuelin, the girl's mouth slightly raised, revealing two beautiful labyrinths.

"Huge brother, go wash your hands. I made pork belly chicken and various shabu-shabu at night. 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, he has a spicy taste, so he has not been able to adapt to Cantonese cuisine.

Only this pork belly chicken ~ www.novelbuddy.com ~ is his favorite dish among many Cantonese dishes.

Soon, Mu Qingqing put the casserole with pork belly chicken on the table, the two worked together to make a variety of shabu-shabu, Pang Xuelin also took out several bottles of beer from the refrigerator.

In this weather, if you eat pork belly chicken hot pot, you must have cold beer to eat.

"Huge brother, pour me a little."

Mu Qingqing held a transparent glass to Pang Xuelin.

Pang Xuelin froze for a moment, and said, "Qingqing, can't you not drink?"

Mu Qingqing smiled and said: "Isn't it going back to Lancheng tomorrow? We're afraid we won't see you again for a long time, Big Brother, you just have a drink with me!"

"okay then!"

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