Liu Ping's voice was very clear, and he said: "It's 15:24:12 Yanjing time. ”

When Liu Ping was reading the time, the people in the control room were also staring at the time on the big screen, and the time was exactly 15:24:12.

Chen Nuo asked Sun Ze and Liu Ping to transmit signals at the same time to detect communication delays, and came to the conclusion that there was no delay in the communication signals between the two IICE devices, which were thousands of miles apart. Even if there is a theoretical latency of less than microseconds, it cannot be tested by current human technology.

Sun Ze couldn't hold back the joy in his heart and said, "The news is synchronous!" ”

Chen Nuo's expression was still unfazed, and he said: "Liu Ping, now the headquarters needs to video with you, what is the light on your side?" ”

Because of the time difference, the time in Yanjing is more than ten hours faster than the time on Azure Island, so it should be early in the morning on Azure Island now.

Liu Ping said: "I have turned on the lights here, and there is no problem with the video screen. ”

With that, both parties turned on the video equipment of the IICE at the same time.

The principle of IICE's video equipment is to present a virtual camera in front of the user through the principle of cross-emission of light, and the virtual camera collects the user's appearance and then transmits it to the device.

Almost instantly, Chen Nuo and Liu Ping saw each other at the same time.

Liu Ping almost jumped up with joy, and he said, "Boss, the signal is so good, I can see every detail of Professor Sun's face." ”

Sun Ze hurriedly adjusted the distance, afraid that Liu Ping would see his black head.

Sun Ze walked back and forth in the control room with the IICE equipment, and the picture on Liu Ping's side did not have any delay or stuttering.

Liu Ping was also walking over there, and the picture signal was quite stable.

Sun Ze's inspection data also came out, and the video and voice were perfect and free.

The experiment on the Lanxin-1 quantum satellite was basically declared a success.

The last test is the test of data transmission, which is what Chen Nuo pays the most attention to.

Liu Ping has prepared a data package, the content of which is all the data about the construction of Bilan Island from the beginning of construction last year to the present, including the basic data of each building and the geography, climate and temperature data of Bilan Island.

If you follow the algorithm of the binary in the past, the total size of the data is 1.5 TB.

Liu Ping clicked Send here, and Sun Ze clicked Accept on the IICE device.

All data will be transferred to the supercomputer through the IICE equipment in Sun Ze's hands.

Transmission in seconds!

Almost instantly, all the data treatment on Liu Ping's side had been transmitted to Jiangcheng.

Sun Ze immediately asked the technicians to check the integrity of the data packet, and ten minutes later, he learned that the data integrity of the data packet was not missing, because of the special transmission method of the quantum satellite, the data packet also has its own encryption performance.

Sun Ze secretly clenched his fists and said to Chen Nuo: "Master, the experiment is complete, everything is within our expectations." ”

Chen Nuo, who had been expressionless, showed a smile at this time, and he said, "Liu Ping, your task is complete, go back and sleep well." ”

After Liu Ping finally checked the IICE equipment, he turned off the video.

The task on the side of the blue island is complete, and the intense work in the central control room is still ongoing.

Because of the different algorithms, the data carrying capacity of quantum satellites cannot be measured by how many data nodes are transmitted per second.

Chen Nuo adopted the algorithm of the Blue Star World, a quantum satellite with 100 billion quantum entanglement pairs, which can cover 1 billion people and communicate at the same time. Communication base stations can be divided into large and small sizes, and can carry 100 to 5 million quantum devices. The earth only needs six to ten Lanxin quantum satellites at the level of tens of billions of entangled pairs, and the establishment of communication base stations of different sizes in different places can fully meet the communication functions on the earth.

In fact, according to the communication rules of quantum devices, humans can build large-scale quantum communication devices on the ground without launching satellites.

However, there are several absolute disadvantages compared to space on the ground, that is, the infringement of equipment by the natural environment.

Rain, strong winds, earthquakes, microbial invasion and human destruction will make the life of large-scale quantum communication equipment very short, in contrast, launching a quantum satellite and hanging the device in low earth orbit, the device will avoid the harmful variables on the ground, which is why Blue Star World will launch the satellite into low earth orbit and ensure that it will still operate for 50 years to provide communication services for mankind.

If the technology of quantum satellites continues to develop in the future, and develops to the trillion-level entanglement pair, Chen Nuo cannot imagine how the history of communication data will change.

Sun Ze checked the operation of the satellite and the base station, and everything was normal.

The next step of the experiment is to implant the existing devices in everyone's hands into the quantum communication components to see if multiple devices can communicate smoothly.

The quantum components in the communication equipment can be bound to the base station, and there are tens of millions of pairs of quantum entanglement with the base station.

A week later, a total of more than 100 mobile phones, more than 40 laptops and tablets were reinstalled with quantum communication components.

A large-scale video conference of hundreds of people was held.

Chen Nuo set a theme for this meeting, that is, to speak casually, transfer files casually, and download documents at will.

At the same time, he asked his employees to conduct experiments in various places where the signal was worst.

Someone was in the basement (in the past, there was no communication signal except for IFI).

There are people in the mountains and forests, and there is no signal in the past.

Someone is directly in the metal room, and according to the shielding principle, all signals will be blocked in the closed metal room.

Under such harsh conditions, the video conference was held at the beginning.

Sun Ze: "After the meeting, there were a total of 134 people, everyone signed in first, and then spoke freely. ”

After everyone signed in, they began to speak casually.

"I'm in the back mountain now, there has never been a signal here, and now I can actually go online! Our tech! ”

"I'm in the basement, I've turned off the IFI, and now I'm able to access the Internet, it's so cool!"

"Now you don't need to display the icons of China Mobile, China Unicom and China Telecom on your mobile phone, it's so cool!"

"By the way, when will our Lanxin communication also set an icon."

"If Lanxin Communication serves the outside world, the three major communication companies in Huaguo will be cold."

Some people take photos of their surroundings, some people transmit huge amounts of virtual reality game clients, and some people even send their own private high-definition videos.

"Who sent that video just now? 4GB of video in seconds! ”

"Kneel down and beg for a little more just that!"

Seeing that everyone was talking more and more excessively, Sun Ze hurriedly controlled public opinion: "Quickly retract the unhealthy video, and the boss is also in the group!" ”

"Scare the pee!"

Chen Nuo did not blame the employees who were excited, and he ordered Sun Ze: "In the next six months, we also need a satellite to meet the communication needs of Huaguo." ”
