The Black Technology Era of Xueba

Xiao Ming's big order here refers to Xia Guo's high-speed railway company preparing to apply quantum communication along Xia's high-speed railway.

In the process of high-speed rail, passenger cell phone networks rely on base stations along the line is the most common.

However, in the long journey and the fast running of the high-speed rail, signal instability is common, which also greatly affects the passenger experience and the reputation of the high-speed rail.

In recent years, the high-speed railway company has been discussing cooperation with the three major telecommunications companies in Xia Guo, trying to increase the number of base stations along various high-speed railway lines, and strive to achieve full access to key routes.

However, the foundation of the three major telecommunications companies is not so simple. The road conditions along the railway, future maintenance, etc. all need to be considered. The most important thing is the construction cost. A rough calculation is just to build the base stations of the main railway lines of the North-South Line. The budget cost is more than 30 billion yuan. The annual maintenance in the future will still require a certain cost.

High cost, large amount of engineering, and low efficiency are the main dilemmas of the current high-speed rail to achieve full signal coverage.

Another way is to deploy a central server on the high-speed rail train, deploy multiple APs in each carriage for full coverage, and let the high-speed rail form a local area network to provide passengers with free Internet access.

Some high-speed trains did this, but the effect was very bad.

The first is that the signal is also affected by the railway environment of the surrounding base stations. There are high and low, sometimes 4G signals, and more often 3G or even 2G signals.

In addition, the number of high-speed rail passengers is also small. When there are many passengers, the central server of the high-speed rail car group will basically be crowded. All passengers will be able to access WIFI, but no one will be able to access the Internet.

In this way, the high-priced rail server and the AP deployed in each train compartment are basically useless.

But quantum communication has given high-speed rail different options, and quantum communication services have no distance and speed restrictions. As long as a small base station for quantum communication is built on each high-speed rail, the small base station is connected to a server located in a large city. The base station then converts the data through a certain means, converts it into ordinary network signals, and then establishes them through APs distributed in each compartment. Internal LAN, then any signal network equipment of passengers can get online.

In addition, the quantum communication base station located in the compartment has no users and speed restrictions, and can meet the network needs of passengers during travel.

It is expected that the 30 billion contract will be awarded to the three major telecommunications companies to establish roadside base stations that do not know the effect and need to be maintained every year. It is better to hand over to Pangu Technology Quantum Communication Company to build small quantum service base stations on each high-speed train.

At present, the communication team of the high-speed railway company has already negotiated with Yu Hong and other high-level personnel in the park.

In addition, Yuhang Electronics Co., Ltd. (fictional) is also on its way to Jiangcheng. They are planning to discuss with Pangu Technology about the cooperation of quantum communication in Xia Guo space exploration technology.

Yuhang Electronic Technology Co., Ltd. has deep cooperation with Xia Guo's space and moon exploration projects. The research and development and production of various communication and sensing equipment of Xia Guo Space Detector have Yuhang Electronic Technology.

According to the speed of electromagnetic wave propagation, there will be a delay in the signal transmission from the moon to the earth. If the Mars, Jupiter, Uranus and even the edge of the solar system are farther away, this delay time will be longer.

It takes one light year for signals at the edge of the solar system to reach Earth. Such signal delays have greatly hindered the development of space exploration.

Imagine that if the space probe encounters difficulties in the deep solar system and requires human instructions to get rid of such difficulties, then it is particularly important to be able to transmit quantum communications in a timely manner without distance and geographical restrictions.

General Manager Liu of Aerospace said: "However, it is not the same with quantum communication equipment. The situation detected by the detector at the scene can be fed back to the ground command in time. Any instructions we have can be issued instantly. The quantum communication equipment on the detector The application can at least advance Xia Guo's space exploration technology to an era. "

President Liu even predicted the steps to explore the cosmic space in the summer of the future: "The first step must be Mars, followed by the asteroid belt, Jupiter, Saturn, and even the edge of the solar system. In our lifetime, we may be able to see with our own eyes what the outside solar system looks like. . "

Xiao Ming will not immediately refuse any cooperation, and will listen carefully to the cooperation agreement proposed by the other party.

What Xiao Ming is most interested in is Xia Guo's space exploration project. When micronuclear batteries came out a few years ago, Pangu Science and Technology will cooperate with the lunar exploration center to supply micronuclear batteries for lunar exploration equipment.

Today, Xiao Ming is happy to cooperate with related companies in space exploration.

However, Xiao Ming has a condition that the engineers of Pangu Technology will participate in the cooperative project.

This is of course no problem, and cooperation is achieved.

Under the instruction of Xiao Ming, Pangu Technology was officially listed on Pangu Quantum Communication Co., Ltd. ~ www.NovelMTL.com ~ Yu Hong is also the general manager.

Quantum Communication Co., Ltd. also quickly established an official website and announced contract information during this period.

"Pangu Technology Quantum Communication Co., Ltd. and Xiaguo High-speed Railway Group signed a quantum communication service order ... The contract value is 13 billion yuan."

"Pangu Technology and Aerospace Technology Co., Ltd. signed a research and development order for space equipment quantum communication ... The contract value is 500 million soft sister coins."

"Pangu Technology and Jiangcheng Airlines signed a quantum communication service order ... the contract amount is 200 million soft sister coins."

No communication company in the world can get orders of more than 10 billion soft sister coins in a very short time like Pangu Technology Quantum Communication Co., Ltd., and the market value quickly came to the fourth place in Xia Kingdom and the top 20 in the world.

"Yu Hong's men will add eggs this New Year!" Xiao Ming personally praised Yu Hong.

Western countries are horrified to see that quantum communication services are rapidly advancing in Xia, and their most worried thing has happened. Quantum communication can be applied to the aerospace field. Will it be used in the military field?

This kind of thing is only known to Xiao Ming himself.

Su Yi has been urged countless times during this period of time. She knows that she cannot continue to fish here and needs to quickly enter the core layer of the life science laboratory.

Su Yi needs to show his ability to excel.

In November, Su Yi formally proposed a biological separation waste classification and treatment technology.

This is a project that is being researched by the Rice Lab. Su Yi regards it as his name.

One week later, students collaborated to combine this method with phagocytosis II colonies and computer waste sorting to write detailed waste sorting and disposal methods.

The manuscript was delivered to Xiao Ming. Xiao Ming looked at more than twenty pages of simple papers and felt that it was necessary for him to look at the students' results.
