The things that should be talked about have been talked about, and Fang Chen really can't bear to continue to abuse Xu Jianshu.

After all, Xu Jianshu is also good to him on weekdays, so he was ready to get up and say goodbye after drinking tea.

But as soon as he stood up, Dean Zhu suddenly said to him: "Do you think Huaxia can use the 3G network around the millennium?" ”

Looking at Dean Zhu's hopeful and knowledge-seeking eyes, Fang Chen only felt that the sky was thundering, and three black lines crossed his face.

Rolling his eyes, Fang Chen said helplessly: "Dean, I understand your good expectations for the country and the people, and hope that Huaxia's economy and communications can develop in great strides, but it is really easy to get the egg when the steps are big, and I expect that Huaxia will be able to use the 3G network around 2005." ”

"Is the 3G network so difficult?"

Dean Zhu didn't care about Fang Chen's disdain, and looked at Fang Chen suspiciously and asked.

Fang Chen preliminarily came up with the 2.5G network technical standard in less than two years, and also claimed that the key technology of the 2.5G network, packet data technology, is the key technology of the 3G network, and the 3G network is just an enlarged version of the 2.5G network Yunyun, but now he is told that it will take 12 years to realize the 3G network.

No matter how you think about it, it feels a little incredible, even fantastical.

Moreover, a thought could not stop popping up from his heart.

Could it be that what Fang Chen said before had an element of bragging?

But it shouldn't!

Although Fang Chen did like to brag, according to his previous understanding of Fang Chen and Fang Chen's perception of people, Fang Chen would definitely not brag about such a big thing.

Fang Chen spread his hands and said: "The 3G network, if it is only in terms of technical difficulty, is not too high, especially when Qingtian has already researched the packet data technology, if you go all out to tackle the 3G network, I will be confident that within three years, I will be confident to take out the 3G network and put it in front of you." ”

In the previous life, Europe came out with a 2.5G network in 1995 and a 3G network around 1999.

At the end of 2000, South Korea, as the first country to eat crabs, began to officially commercialize the 3G network.

Soon after, Towa began to use the 3G network in 2001.

The large-scale use of 3G networks around the world was around 2004 and 2005.

As for Huaxia, it is the latest among the major economies, and the first 3G network license was only approved in 2009.

But in this life, with his existence, Qingtian Communications will be able to break through the 3G network in less than three years.

After all, as a professional practitioner in the communications industry, although he cannot independently develop 3G networks, he can ensure that the research line of Qingtian Communications will not deviate and can reach the target at the fastest speed.

But the problem is that the 3G network was not suitable for China at that time.

He thinks it would be a good choice to wait until around 2005 to start commercial 3G networks with European and American countries, that is, four years in advance.

At that time, Huaxia will not only be richer, but maybe he has already made a smartphone?

"Then why would you put the time of using the 3G network in China until after 2005, so long?"

After listening to Fang Chen's explanation, Dean Zhu became even more curious, and the whole person had a feeling of being in the clouds and mist, surrounded by clouds and mountains.

"So, you don't understand mobile networks. Fang Chen sighed.

Dean Zhu's face turned black in an instant, and he looked at Fang Chen with an unkind expression, wanting to say something, but in the end he didn't say anything, so he could only glare at Fang Chen fiercely at the end and give up.

To say that he is a person who has always been sincere and based on facts, he never thinks that he can understand much in other fields that are not his own professional skills.

If he met other experts and scholars, even if he was a worker, he would be able to accept it with an open mind and ask questions with an attitude of learning and asking for advice.

But these words came out of Fang Chen's mouth, how could he have a feeling of being unbearable!

Thinking about it, he thought it was probably because Fang Chen was too angry and his mouth was too cheap.

"First of all, the cost problem, the mobile communication base station of the 2G network, the coverage radius is about 5-10 kilometers, and the coverage radius of the mobile communication base station of the 3G network is about 2-5 kilometers, which means that the same base station, a 2G network base station can cover the area, it takes four 3G network base stations to achieve, and the cost will increase by four times. ”

"This is no way to do things, 3G network wants to transmit faster, naturally it is inevitable to be higher than the 2G network, the frequency will be higher, which will inevitably lead to 3G network than 2G network wavelength shorter, short transmission distance, signal attenuation is larger, weak penetration, poor ability to wrap around. ”

"Then the construction of a large number of 3G network base stations is obviously very inappropriate for China's vast territory and barren economic conditions. ”

"If you really want to build a large number of 3G networks, you have to wait until the people have the wealth to match the 3G network, or the necessary needs. Fang Chen said slowly.

Hearing this, Dean Zhu couldn't help frowning slightly, feeling ashamed in his heart, this was something he really didn't take into account.

It is true that as Fang Chen said, the area of Huaxia is too large, and the people are too poor.

The existence of a cheap and affordable base station like a 2G base station that can solve the needs of most people to make mobile phones is the most needed existence in China now, and even in the next ten years.

If it is really just to reflect the progress of science and technology in China, and blindly build a large-scale 3G network, it is a manifestation of great success.

Looking at Dean Zhu's somewhat remorseful appearance in his heart, Fang Chen couldn't help but smile in his heart.

He relied on Dean Zhu's ignorance of the future and the development of communication technology to bully and bully Dean Zhu.

Compared with 2G base stations, the attenuation of 3G base station coverage is nothing.

If Dean Zhu knew about the attenuation of 4G base stations and 5G base stations, he would probably be scared to death.

In the 5G era, the coverage area of a base station is only 500 meters, and the coverage area is only 1/400 of the 2G base station, which means that the coverage area achieved by a 2G base station needs 400 base stations to reach in the 5G era.

However, it is precisely because of this consideration that the large-scale commercial 3G network in China will be four or five years later than that of Europe and the United States.

In addition, before 2009, when smartphones had not yet begun to become popular, most people around the world did not have the need to use high-speed Internet access, so it didn't matter if it was a few years later.

In addition, the reason why China is four or five years later than that of European and American countries is that in addition to the gap in demand and wealth, there is another very important reason.

First of all, European and American countries, especially European countries, are some small countries with high population density, but the more users in the coverage area of a base station, the lower the construction cost.

For example, if they are all countries with a population of one million, but the difference in area is ten times, then if a country with a large area wants to cover the whole country, the number of base stations that need to be built is ten times that of a country with a small area, and the cost is naturally high.

As the third largest country in the world in terms of territorial area, Huaxia wants to cover the whole territory of the base station, and the cost is obviously much higher than that of those small European countries.

As for the American side.

Although the territory of the United States is about the same size as that of China, the national conditions of the two countries are still different.

Huaxia construction of base stations, electricity, roads and other infrastructure related to people's livelihood, basically can be said to be costless.

For families living in the mountains, more than a dozen or even a few households, building power lines, building communication base stations, building roads, etc., this seems to be a matter of course in China.

But if you look at the cost and make a profit, these are very loss-making transactions.

This situation is even more impossible in Western countries, after all, their enterprises are all private, and private enterprises must consider profits, and it is impossible to do this kind of stupid thing that will not be able to recover its capital in a hundred years.

This also causes that in the 4G era, there is still a 4G network signal in the city, but as soon as you get out of the city, even if you take a subway, there is only a 2G signal, and there is even no signal.

But Huaxia did it without hesitation.

However, the cost of doing so will inevitably be paid by the whole people, which invisibly pushes up the construction cost of more advanced network facilities.

It is poor, and then the cost is still high, so Huaxia's interest in building 3G base stations is naturally not high.

That is, the rise of smart phones, the emergence of a large number of software applications, and the demand, which has made a large number of 3G network construction waves in China.

However, in later generations, Huaxia's 5G network construction also faced these two very embarrassing problems.

Although the 5G network is advanced, there is no scenario where the 5G network must be used, and the short videos, live broadcasts, etc. that appear in the 4G era can still be well experienced by using the 4G network.

In addition, the construction cost of 5G base stations is high, which is three or four times that of building 4G base stations.

So much so that the tariff remains high, and people naturally have no interest and need to replace the 5G network.

The reason why a large number of 5G base stations are built in China can only be said to be taking precautions.

It's like building roads before you want to get rich.

Regardless of whether there is a need to build a road in this village, first build this road to the entrance of the village.

After all, only when the road is built first, some products and people in the village can go out.

Once there are 5G applications, Huaxia, which has already covered a large number of 5G networks, will completely ride the dust, leaving other countries 18 streets away.

However, the prosperity of Huaxia's short video application, the sailing of a certain sound, the right to speak, the influence, and even the unreliable blatant sanctions, are all related to the huge scale of Huaxia's 4G network construction.

It is precisely because Huaxia has built more than 60% of the world's 4G base stations and laid fertile soil for these short videos that these short video applications can come into being.

If there is no such a huge number of 4G network construction, there will naturally be no appearance of these short video applications.

"What you said is indeed reasonable, it seems that there is still a long way to go for China's future scientific and technological progress. Dean Zhu said self-deprecatingly.

He originally thought that Fang Chen said that he only started to use the 3G network in 2005, because of the technical strength of Qingtian.

But now, it's his problem.

It is he who has not changed the degree of economic development in China and the purses in the pockets of the people to the point where they can use the 3G network.

"Therefore, I think that compared with making 3G, how to reduce the cost of 2G network construction, so that more people can afford to use mobile phones, so that the Chinese people's phone bills are less, is the way we need to go in the future. Fang Chen said in a deep voice.

This is also the guiding goal he set for the R&D department of Qingtian Communications.

Now Ericsson's quotation for the cost of building a 2G base station is as high as 40 million, according to this price, if you want to cover a city in Yanjing, you need 12 billion.

If you need to cover the whole country, I'm afraid you need seven trillion.

Such a price is simply too high and too high.

In the previous paragraph, Shen Wei gave him, the construction cost of Qingtian 2.5G base station, under the condition of ensuring 30% profit, basically has to be reported to 32 million.

Although it is 8 million lower than Ericsson's offer, it can basically be said that it is quoted by stepping on Ericsson's cost line, but it is still a little expensive.

According to Shen Wei's survey of Ericsson's 2G base station cost, it is basically predicted that Ericsson's 2G base station cost will be about 30 million.

Then, the offer of 32 million will make Ericsson very uncomfortable.

After all, if they don't reduce the price, it means that they will not be competitive compared to Qingtian, but if they reduce the price to 32 million to compete with Qingtian, then there will be no profit at all.

The profit of 2 million is only 8% for the base station with a cost of 30 million.

As far as the management level of Ericsson and other Western countries is concerned, the profit margin of 8% is too small, and it is better not to do it and put the money in the bank to eat interest.

You know, even in Europe and the United States, the bank interest rate is about 7%, 8%, if Fang Chen and Soros snipe the pound and the like, the interest rate of the pound and the German mark can rise to more than 10%.

However, Qingtian's offer of 32 million has one thing that Fang Chen is very proud of.

Although the quotation of 2.5G network construction this time is much lower than that of the same type of foreign products of the same level, it is no different.

After all, other people's products come out earlier, have more audiences, higher recognition, better product quality and technology, etc., and in order to survive and develop, Qingtian has to offer a lower price than others.

For example, game consoles.

If the price of the DynaSky console is the same as Nintendo's.

Unless consumers have their brains pumped, they will not buy Nintendo's game consoles, but will buy Qingtian's game consoles.

But this time, the reason why Fang Chen quoted the price of the 2.5G base station as 8 million lower than Ericsson is not because the product is not good, the reputation is not big enough, and the technology is not advanced.

On the contrary, DynaSky's 2.5G network is more advanced in technology than Ericsson, and its product performance is stronger, and it is the mainstream of installation and use in major post and telecommunications offices.

Not to mention that as a Chinese enterprise, Qingtian itself also has a huge home combat advantage.

At the very least, Ericsson can't be like him, looking for Dean Zhu to give him a buff at every turn, right?
