Hu Yiting continued: "We are not allowed to waver if we make a choice, we choose the IP protocol network, abandon the circuit switching network, although the protocol network has the shortcomings of packet loss, jitter and disconnection, but the circuit switching network has no voice jitter, other packet loss, disconnection These two major defects are all there, in addition to crosstalk, sliding code, and call loss, these three major pitfalls are the magic weapon, if Huachuang continues to boil in it in the future, it will be bitter, and there will be a bunch of technical problems to be solved.

As leaders, you must also maintain a high degree of consistency with me in words and deeds, and resolutely crack down on those heresies in the company! Whoever says that ISDN and ATM have a future in the future will be tied up and burned by me!"

Hu Yiting humored, he laughed first, and Wu Hengyuan also smiled: "Mr. Hu will never be wrong in technology! I am 100% confident in this!"

Lin Yun smiled: "I was a little confused, but when I heard Mr. Hu's explanation, I immediately felt so stupid!"

Zhu Jun said with a smile: "Mr. Hu's vision is really shining brightly, I admire it! I really admire it! Now the CEOs of some telecommunications bureaus ask us if we have ISDN equipment, and also ask whether our program-controlled telephone exchange supports the access of ISDN technology in the future.

Our previous caliber was still relatively vague, saying that the interface equipped on the switch can support all international general data exchange support equipment, and we should simply explain it to them in the future, so as not to be fooled by companies such as Huachuang.

Like I know that Huachuang now regards the full support of ISDN access as a selling point, what is there to brag about, as long as there is a data interface, what equipment can not be connected, which one supports 10,000 parallel programs without data transmission function. ”

Wu Hengyuan said: "I estimate that Huachuang will soon build domestic ISDN data support equipment, and in the future, it may have to compete with Ascend for the client modem order in the telecom ISDN plan, and now Mr. Hu has taught us a lesson, we will never touch this piece of pie, let Huachuang fight with the Americans, hahahaha." ”

Lin Yun said: "There is another thing, now Japan is engaged in PHS mobile call business, we have recently contacted domestic experts to study it, and I think that the technical difficulty of this thing is not great, but it is completely two ways with the 3G technology that Mr. Hu values you, I don't know if it is worth the effort." ”

Hu Yiting is really a little difficult now.

He originally looked down on PHS's clever technology, which was a high-power cordless phone, and it was a book that could be written in the history of telecommunications.

But the so-called good birth is not as good as the birth of the skill, transported to the gold discolored, transported to the iron is also born, in the history of China Mobile Company was forcibly split from the womb of China Telecom, Telecom only left the fixed line business, when the sadness is infinite, and suffering from not getting the license of the mobile phone, can only watch the mobile son after the separation of the family after the day long to eat spicy food, and then China Unicom, such as the gray grandson who was not in the eyes of the telecommunications law before, also joined the big bowl of wine and large pieces of meat eating the team, at that time the mood of the telecom was like wearing a vest on the snow barefoot naked general, how desolate and desolate。

Therefore, when telecommunications met PHS, they immediately sparked, don't treat the village chief as a cadre! No matter how dirty the radish is picked up in the bowl, it is a dish! Since it can rely on the existing fixed-line network as a mobile phone to make calls, no matter how many problems there are, it can't be taken care of. And this business can effectively evade supervision, you say that I can't operate a mobile phone business without a mobile phone license? I'm sorry, Lao Tzu's new business is not a mobile phone! It's a cordless phone! You open your eyes and see, Lao Tzu's signal transmission depends on the fixed telephone network! That is, the last few hundred meters of signal depends on radio!

What? You say that this technique has too many shortcomings and has no future? Hehe, do you know how it feels like to be in the middle of the road after you have crossed over? Do you know what it means to be hungry and not choose to eat? There are a bunch of research institutes and thousands of experts and senior engineers in Lao Tzu's house, do you think I won't know that this is a bowl of shit mixed with sugar? Hurry up and get out of the way for me! Don't affect Lao Tzu's mood when eating!

As a result, relying on Telecom's resentment of the mobile phone business, PHS has blossomed all over the land of China, and after the spread of users, it has become more than 10 times larger than the 7 million users at its peak in Japan, the birthplace of Japan, and there are more than 90 million users! A slogan of "using the price of a fixed telephone to call a mobile phone" has really helped Telecom attract countless customers.

At the beginning, there were also masters in the telecom who claimed that even if they didn't make a penny, they had to do it, even if it was worth it for the disgusting of the two kings and eight lambs, and it turned out to be a lot of money, and then the country looked out of control, and quickly got a mobile phone license for the telecom uncle, and the uncle just closed the stall, and waved the knife from the palace to practice CDMA magic skills, and the previous hundreds of billions of base station equipment investment was wasted.

At the beginning, Hua Chuang and Qin Zhenfei were stupid and didn't think that such a LO forced technology like PHS could have a future, so they didn't touch it, and finally let ZTE earn HIGH by providing equipment to PHS!

Now this choice is also placed in front of Hu Yiting, which simply makes his technical controller a little crazy, facing Lin Yun's problem, he feels itchy all over, but he has nowhere to scratch, so he has to twist his body hard, trying to sort out the problem.

"PHS...... No, mobile local call, this mobile local call...... I do, but ...... It's so LOC...... It's not that I don't love money, it's just that I still want face...... In the future, telecommunications will fall into this pit, and the people of the whole country will have to say that I fed the...... This reputation stinks...... I...... I...... I'm a little scared...... In case it is suddenly blocked by the Ministry of Information Industry in the future, I won't be able to cry without tears......"

Lin Yun asked like a cannonball: "It turns out that you know this technology, Mr. Hu!? You are really amazing! Can you tell us? Why is it shameless? Why do you want to ban it? What is the matter with the Ministry of Information Industry? Is the Ministry of Electronics Industry going to change its name?"

Hu Yiting scratched his head: "Of course I understand this thing, I will also design a single-chip solution, band transceiver, baseband, protocol control block, application processor, voice encoder, analog path, chord ringtone generator, power management, LCD screen management, key area management, USB interface management are all designed in one chip......! I'll do it in minutes!

This is a cordless telephone technology, its base station capacity is particularly small, only a few channels, the transmission distance is also very short, only tens of meters or one or two hundred meters, so the operator needs to invest a lot of base station, like sprinkling pepper noodles, the entire community almost a building installation may not be able to ensure the signal, this thing except for small villages and remote mountainous areas, basically has no application prospects, and it will be the transition period between fixed telephones and mobile phones in the future, so that it can jump for a few years. There are few high-rise residential buildings in the footbasin chicken, and the general residential area is crowded with the kind of two-story and three-story matchbox small houses, and the mobile tariff of the footbasin chicken is particularly expensive, so this LO forced thing is not a big problem to use in those places, and it is quite cost-effective, but it does not conform to the national conditions of our country, nor does it conform to the scientific and technological strategy, and it is a purely commercial choice. ”

Lin Yun said: "So that's the case." But now there is an American company called UTStarcom has developed access network technology, and from Panasonic to engage in base station and mobile phone patent licensing, is looking for cooperation in China, the last time the provincial telecommunications suppliers held a meeting, several telecommunications directors said that they had visited, and asked me what is going on with this technology? Is it good to do it? How can I answer, we haven't studied this thing. ”

Hu Yiting smiled lightly and proudly, and said on his feet: "What's so difficult about this, UTStarcom hasn't made an IP soft switch yet, and is still engaged in circuit switching, and the network will be paralyzed at every turn, if I want to do it, they won't have a way to live." Didn't they just get $5 million in venture capital from SoftBank Masayoshi Son, believe it or not, I burned them dry in minutes. ”

Zhu Jun was itchy when he heard this, and his eyebrows fluttered: "Since the Japanese are willing to throw money into it, it means that this technology is still quite marketable! I heard that there are already five million users of the Japanese PHS network, how many base stations do you have to smash into it?"

Mr. Hu, since you understand, let's do it! That's the American and Japanese enterprises, and it's not a pity to burn them dry, but how can we burn them dry?"

Hu Yiting sneered: "I'll come up with a complete set of design plans, won't I burn them dry." The problem is that this technology is born with a disability in the womb, and no matter what method is used, it can't be compensated.

A GSM base station can cover several or even dozens of square kilometers, do you think how many of them have to be installed for the tuning of tens of meters to one or two hundred meters of the PHS base station?

Once users are concentrated in a certain area, such as concerts, stadiums, and convention centers, the PHS base station will be blocked immediately, and even if there are free channels around, they cannot be moved to help alleviate the congestion. However, the large base station of GSM mobile communication can mobilize all channels in the coverage area to this dense communication area, so as to ensure smooth communication.

That's what this thing is. ”
