"Hello everyone, I am Ying Shu, the head of the communications engineering department of Jiuzhou Technology. In fact, I am not suitable to explain our company's communications engineering technology to you today, because the successful research and development of this technology is inseparable from Li Cun, Wang You, The efforts of people in charge such as Zhao Wei are also inseparable from the efforts of Zhan Kunhu, the head of the satellite R&D and manufacturing department under our aerospace department, and the engineers, scientists, mathematicians, and technical employees of the two departments.
What I personally know is only a general overview. If I go deeper, I am only a little good at projects such as data encryption, transmission and analysis and optimization of satellite communication projects. "
In his self-effacement, Yingshu did not mention his extremely impressive resume and academic status, nor did he mention his family background.
It's just that the old foxes present have automatically filtered out this self-effacing attitude. In their opinion, the person who can be entrusted by Gu Qing with important tasks in this most important project of scientific research and technology cannot be an ordinary genius.
Ordinary geniuses are the targets of competition for companies like ours...
After introducing himself, Yingshu did not directly introduce the PPT picture, but first said: "In recent years, mobile phone manufacturers, system research and development companies and other technology companies have launched satellite communication services for individuals. If this is technology decentralization, then It took decades for satellite communication services to be devolved to commercial and civilian use, which can already show how difficult this technology is.
In the current mobile Internet world, 4G/5G communication network speeds can already meet the daily Internet needs of ordinary users. However, the mobile Internet market is now approaching saturation, users are changing phones less frequently, and everyone is competing for the stock market.
5G has been available for several years, and there is no better application to be implemented now. Now Tesla President Musk’s Starlink plan, or the 6G communication technology that is still being debated in academia, can actually be regarded as broad satellite communication technology. "
Amid the disbelieving looks of senior executives of technology companies, Yingshu shook his head modestly and said: "Of course, the satellite communications currently mastered by Jiuzhou Technology are not 6G communications technology. It can even be said that in terms of use, it is worse than 5G. , because the cost of our Jiuzhou satellite communication technology is still a bit high.
In fact, after our Daxia official Tiantong-1 project satellite 01 was launched, a certain letter company in our Daxia released a Tianyi satellite phone. In addition to the same call charges and monthly fees as ordinary mobile phones, this satellite phone has In addition to renting, there is an initial installation fee of 1,000 yuan. The lowest rate for making/receiving calls is 1.8 yuan/minute, and the highest is 66.8 yuan/minute. The mobile phone data usage rate is as high as 16 yuan/Mb.
If users do not use satellite communication functions frequently, the cost of operating and maintaining satellites will become very high.
This dilemma may be rewritten in the next two years. "
After Yingshu said this, he directly turned the PPT on the main screen to the next page.
That's a picture of the hot surface of the sun.
We have had close exchanges with experts from the Space Environment Forecasting Center of the Daxia Academy of Sciences and learned that Blue Star is currently in the rising stage of solar activity, and the sunspot phenomenon is increasing day by day. Several large structures with complex structures have appeared on the sun in recent days. The sunspot swarm causes M-class flares to erupt almost every day, and occasionally X-class or higher flares are produced.
A sufficiently strong solar explosion will eject a large amount of energy and matter into the surrounding space. This energy and matter usually manifests itself in the form of electromagnetic radiation, high-energy charged particle flows and plasma clouds, and their impact on blue stars is no less than for some concept weapons.
In the past two years, our sun has erupted more than once with X2.2-level large flares. When a large flare erupted, our country happened to be on the sunny side in Daxia. Only ten minutes after the large flare erupted, it sharply intensified. The electromagnetic radiation reaches our Daxia area, causing sudden harassment of the ionosphere in the Daxia area, interfering with the propagation of wireless signals, and causing the attenuation of shortwave radio signals.
Internationally, X-ray flares are divided into five levels according to the magnitude of the peak flux of soft X-rays, namely A, B, C, M and X. The energy released increases by 10 times in sequence.
Flares below C level are small flares, M level flares are medium flares, and X level flares are large flares. Level X2.2 means that the peak flux of soft X-rays from the flare is 2.2×10-4 watts/square meter, which can release a huge energy of 1025 joules in 1 second.
The energy released by that flare was roughly equivalent to billions of giant green bombs exploding at the same time.
Our blue star is currently in the 25th cycle of sunspot activity. It is expected that by 2025, sunspot activity will reach its peak. By then, the sun that created us and raised us will burst out with frequent and intense energy.
Just like the moon's influence on tides and living things, the peak activity of sunspots will also affect every plant and tree on our blue star, and new drastic changes will occur.
When 3G, 4G, and 5G networks are subject to frequent disturbances and fluctuations, users often see news about natural disasters in the news, and even when the number of people experiencing natural disasters increases, satellite communications will be the biggest focus of communications engineering.
For military, commercial, and civilian purposes, satellite communications have transmission capabilities comparable to those of 4G communications projects. Kyushu satellite communications technology, which can be upgraded to close to the transmission capabilities of 5G communications projects in the future, will surely become a must-have technical function for smartphones in the new century. "
He is obviously a science and engineering man who has been obsessed with research and development all year round, but he doesn't know what happened to him, and he actually started to sell anxiety, which made many high-level people in technology companies twitch.
Perhaps this is the connection between trust and strength.
If an ordinary company were to engage in this kind of publicity to attract investment, no one here would be willing to invest money, and it is very likely that security would be called directly to pull out this person who is deceiving the public.
But this time it was what the senior project leader of Jiuzhou Technology said.
Even Mr. Xia Weiren, who had seen many big storms, could not help but frown and think deeply.
It was Xia Wei's long-term strategy to launch commercial and civilian communication technologies around the Daxia Beidou project. Although limited by geopolitical factors, this project can only be launched locally, but there will definitely be opportunities to expand its impact in the future. regional.
Now Jiuzhou Technology has also stepped in, and it seems that it is not a temporary initiative, but the technical achievements of many years of hard work have been implemented, which will be difficult to handle.
Is it like when we were developing smart phone systems, following Kyushu Technology to let the other party resist the pressure, and our own Hongmeng secretly develops?
