Chapter 508: Feeling like flying, entering the 3G era ahead of schedule
Penyang arrived in Jiangzhou after a long journey.
Wang Xiang also led his team to greet the Penyang group at the airport.
Penyang was still quite surprised. He did not expect that the general manager and chairman of Changtian Technology would come to greet him in person.
Changtian Technology is quite generous. It directly rented a floor in a relatively good hotel in the center of Jiangzhou as a temporary accommodation for technical personnel from Penyang and Warwick.
After Penyang met Wang Xiang, he immediately had a sincere discussion.
The content of the discussion is also related to the construction plan of 3G base stations.
Including the location of construction, the number of base stations and the effects to be achieved, etc.
Penyang said very modestly: "This is also our first contact with 3G technology. The whole team is still in the trial and experimental stage. We still hope that Mr. Wang can bear with us."
Wang Xiang laughed and said: "Manager Pen, you are being polite. Warwick has rich 2G base station construction technology. This is a process of mutual learning and mutual promotion."
3G communication is not connected through satellites, but through base stations and optical fiber links one by one, which can ensure the fastest network and communication speed.
The construction of 3G communication network mainly includes several important structural components.
Core network (circuit domain, packet domain, signaling network and other related facilities).
Wireless network (base station controller, base station and other related facilities).
Bearer network (synchronous network, trunk transmission network, access transmission network and other related facilities).
Business network (intelligent network, SMS center, other business engines and business management platforms, etc.).
Support network, etc.
Main infrastructure equipment, including: transmission network, power system, machine room, tower mast, etc.
There is no big difference between 2G and 3G in terms of equipment.
The address where the core network is built must be at the Changtian Technology headquarters.
Chen Xiao spent more than two million some time ago to buy the entire building where Yangtze Technology's headquarters is located.
This building only has four floors, which is not too high. Considering the low housing prices in Jiangzhou, the price is not too expensive either.
Therefore, the core network construction address is also placed on the fourth floor.
According to Penyang's calculations, the best location for building base stations is the 2G base station that Huawei has built in Jiangzhou. After the 2G base station is modified, it can completely operate as a 3G base station.
Warwick has a total of three 2G base stations near the headquarters of Changtian Technology and is preparing to carry out a comprehensive transformation.
So now comes the problem.
To exchange data between the core network and the base station, it must pass through optical fiber.
The straight-line distance between the two places is 1 kilometer.
And if you take the municipal route, it will take 3 kilometers.
Whether it is taking the open line in the sky or the underground pipeline, it is very inconvenient.
In the end, Chen Xiao made the decision and directly bought an independent bungalow near one of the base stations and converted the bungalow into a core network workspace.
Work started immediately.
Chen Xiao left the matter to Wang Xiang and went back to school in good order.
The end of June and the beginning of July are exam weeks.
No matter how awesome you are, you still have to take a test.
Chen Xiao is also considered a relatively low-key person. Unless he has no choice but doesn't have time, he doesn't want to ask the school for special privileges for any reason.
On this day, Wang Xiang and Pen Yang took the technical team to inspect the construction site of the communication base station.
Xiangyang Street, Jiangzhou City, where the Huawei 2G base station closest to Changtian Technology Headquarters is located.
It stands to reason that Warwick is only the builder of the base station, and the ownership should be Xia Guo Mobile or telecommunications companies.
Therefore, the owner of this base station is Xiaguo Telecom, not Warwick.
However, with Warwick's communication, Warwick can transform these communication base stations and conduct experiments, provided of course that it does not affect Xia Guo Telecom's communication services.
Xiangyang Street, formerly known as Xiangyang Village, has vast farmland and private houses scattered among it.
Ten years ago, Jiangzhou's urban expansion was included in the scope of urban reconstruction. Farmland was expropriated and houses were demolished.
But the work of the masses is the most difficult.
Even if demolition solves your rental problem and social security problem, some people are still not happy.
The Wang Zhiqiang family, located 200 meters next to the base station, initially refused to be demolished for various reasons.
Now, 10 years have passed. His neighbors and surrounding farmland have been demolished and requisitioned, and roads and shops of varying heights have been built around them.
Only Wang Zhiqiang's family lived back from the street, and right under the iron tower, which was quite inconvenient.
Ten years later, Wang Zhiqiang's father and mother had passed away, and the house was dilapidated.
He wanted to find a wife. When the woman saw that his family was so poor and lived in a leaky bungalow, she was even more unwilling to be with him.
Wang Zhiqiang, who is 38 years old this year, is alone. He works at a nearby construction site during the day, picks up some rotten vegetable leaves at the vegetable market at night, and returns to his bungalow to eat and be alone.
This is a bungalow. There was no electricity or running water 10 years ago, and there is still no electricity or running water 10 years later.
Wang Zhiqiang was quite envious when he saw that his neighbors all lived in resettlement houses arranged by the government, with electricity and water, and one household was divided into two or three rooms.
Moreover, his cousin Wang Zhigang, who used to be poorer than his family, also had social security and housing problems solved after the demolition, so Wang Zhiqiang regretted the birth of his daughter-in-law.
Wang Zhiqiang approached the government two years ago, hoping that the government could demolish his house.
His demands are not very high, as long as they are consistent with the previous compensation standards for his neighbors.
But it is a pity that the relevant departments have no corresponding demolition plan.
The reason why the original demolition conditions were so favorable was because real estate developers hoped to cash in by building commercial centers and some residences after the demolition.
These projects have ended long ago, and the real estate owners have all fled. How can the relevant departments have the funds and policies to demolish them for you?
Wang Zhiqiang regrets it!
This morning, Wang Zhiqiang went to the labor market with his tools, waiting for employers to hire him.
But from 6 a.m. to 1 p.m. no one took notice of me.
Wang Zhiqiang was very disappointed and returned home carrying his tools.
He was very hungry and his stomach was growling, but he had no work or income today, so he had to go to the street and buy two steamed buns to satisfy his hunger.
As soon as Wang Zhiqiang walked to the door, he found a group of people wearing clean suits and leather shoes pointing in front of his bungalow.
This time Wang Zhiqiang felt a little excited.
Wang Zhiqiang thought that staff from relevant departments were coming to demolish his home.
He threw down his working tools and walked over, asking: "Boss, are we going to demolish this place?"
Wang Xiang looked at Wang Zhiqiang and said, "Are you the owner of this place?"
Wang Zhiqiang nodded quickly and said excitedly: "Yes, yes, I am."
Wang Zhiqiang quickly found a pack of Tianxiaxiu that was wrinkled and yellowed from his bag, took out a few cigarettes from it, and handed them to Wang Xiang and the people in Penyang.
Penyang often supervises construction at the construction site, so if Huazi can smoke, so can Tianxiaxiu.
And Wang Xiang has quit smoking.
Wang Xiang said: "We are not here to demolish it, but we want to ask you if you are willing to sell this house to us?"
Wang Zhiqiang was immediately disappointed and said, "If it's not for sale, it's not for sale. Where will I live if it's for sale?"
Wang Zhiqiang still wants to wait for the demolition, because the demolition can solve his social security and also need to divide his house.
Wang Xiang laughed and said, "The price is 150,000 yuan."
Wang Zhiqiang was stunned for a moment.
150,000 is not a small number.
The resettlement houses in Zuo Ling Ju only cost at most 50,000 to 60,000 yuan each (the resettlement houses are located in the urban-suburban fringe, the quality is not high, and the price is cheap). For 150,000 yuan, you can buy two or three sets, and you can still have tens of thousands left.
.
These tens of thousands can be used to supplement Wang Zhiqiang's social security, and in addition, there is still money to marry a wife.
This is more cost-effective than demolition.
Wang Zhiqiang said very doubtfully: "Is it true or false?"
When he learned that Wang Zhiqiang did not have a passbook or bank card, Wang Xiang directly asked someone to bring cash.
The money can't be fake.
After two days of negotiations, Wang Xiang confirmed that the owner of this square building was indeed Wang Zhiqiang. The two parties signed a contract and completed the sale of the house (this is a parallel world, don’t think about it in real life, where homesteads cannot be bought and sold.
article).
Wang Zhiqiang took the money and quickly went to buy a house.
He probably didn't expect that his decision would bring him more unexpected surprises more than 10 or 20 years later.
Changtian Technology's Luban Construction Co., Ltd. (100% controlled by Changtian Technology) spent a week completely renovating the bungalow.
Not to mention, after the renovation, the house, the garden outside, and the surrounding private land look like a paradise hidden in a big city.
Of course, the final modification is the security system.
Because the core network is to be built here, there is only one door for entry and exit, and the rest of the place is equipped with surveillance cameras, alarms and barbed wire.
Warwick began to build the core network and lay optical fiber from here to the base station.
Chen Xiao's decision to buy the land was a very wise choice.
Because from the square to the base station, the entire pipeline network route will pass through Wang Zhiqiang’s former private land.
Even if it is excavated, it will not disturb others.
In mid-July, all renovations were completed.
The construction of the 3G communication experimental network is completed.
Warwick directly dispatches technical personnel from Shenzhen City to stay at the core network points to assist in debugging related networks.
Chen Xiao, Ren Fei, Wang Xiang, Penyang and other senior executives from Changtian Technology and Warwick were all there.
Today is the day to test the domestic 3G network.
Even though Ren Fei was on vacation, he came all the way from Shenzhen City.
Both Chen Xiao and Ren Fei have a mobile phone in their hands.
Chen Xiao is a 3G mobile phone from Nokia.
This is because the mobile phone was sold in Xiaguo and was blocked from the 3G network.
The technicians of Changtian Technology have restored the 3G function of the mobile phone.
In Ren Fei's hand is a Motorola A1000.
This was given to Ren Fei from Motorola.
This phone is a 3G phone with a large touch screen. It is equipped with the Symbian UIQ system and can install Java programs.
These functions are quite awesome.
Ren Fei often travels overseas on business, especially to the United States, so his mobile phone already has 3G capabilities.
However, after returning to China, because there were no 3G communication base stations and service providers did not provide 3G services, the 3G functions were basically abandoned there.
Chen Xiao smiled and said, "Mr. Ren?"
Ren Fei was in a very excited mood at this time.
If this test is successful, it means that Warwick can independently master 3G communication technology.
This is very meaningful for Warwick's global competitiveness.
Ren Fei and Chen Xiao both opened their phones at the same time and inserted the 3G card made by Changtian Technology into the phone.
Chen Xiao’s phone number is 0001 and Ren Fei’s phone number is 0002.
Their mobile phones can only make calls to each other and are not connected to the national communication network.
But you can connect to the core network and access the Internet by linking to the base station.
The two began testing.
The first is to make a phone call.
There was no problem making phone calls, the line was clear and very stable.
The two of them actually made a 3G video call through the phone's built-in video call function, and there was no lag at all.
Warwick technicians have been testing the mobile phone data of the two people.
Both the call quality and the network data surprised Warwick's technical staff.
This kind of quality completely exceeds the existing 2G network.
Chen Xiao tests downloading and uploading files.
Relevant data soon appeared in the technician's backend.
The uplink rate is 6.13Mbps and the downlink rate is 7.98Mbps.
Uplink (MHz) 1920-1980, downlink (MHz) 2110~2170.
Shock!
Warwick's technical staff were extremely shocked.
Changtian Technology's 3G technology uses the relatively mature FDD modulation method, but both the call quality and network efficiency are better than those of Nokia, Alcatel, Ericsson, Cisco and other communication companies.
It can be said that this test almost directly established the advanced position of Changtian Technology's 3G communication technology in the world.
It should be invincible!
Warwick's technicians cheered, screamed, and hugged each other excitedly.
How could they not be excited?
In order to break through 3G technology, they spent countless days and nights overcoming difficulties, but with little success.
But today they succeeded.
And this success is completely different from directly spending money to buy technology from the West.
They achieved success through close cooperation with Changtian Technology and unreserved cooperation, which gives them a sense of accomplishment.
Chen Xiao also breathed a sigh of relief.
Not because of anything else, but because after being reborn for so long, I can finally use my mobile phone to surf the Internet relatively smoothly.
Finally, I don’t have to use a junk feature phone anymore.
Ren Fei's eyes were a little moist and his forehead was covered with sweat.
He took out a square towel from his bag and wiped the sweat from his forehead.
"Mr. Chen, congratulations!" Ren Fei said.
Chen Xiao also smiled happily and said, "Mr. Ren, congratulations."
Ren Fei joked: "Next step, the two of us can discuss how to divide the spoils."
Warwick actually has several 3G projects that can be discussed, but because he does not have the relevant technology, he dare not discuss this kind of business.
But it's different now.
Now that the technology is available, so is the experience.
Ren Fei is certainly confident.
Chen Xiao laughed and said: "How about setting up a communications service company in Warwick and popularizing the 3G network first?"
