5G is the most important "weather vane" in the current global mobile communication competition, and 5G has always been a hot spot. After all, in the information age, there is no difference between mastering communication and mastering life. Among them, the second seed is satellite communications. Musk's starlink program includes sending 12,000,000 satellites to the Earth's orbital plane in satellite constellations, providing 24-hour high-speed communications to the world, and incorporating remote areas that once could not receive signals---- oceans, forests, deserts and other ---- into the information Internet. This is also one of the main reasons why it is so popular.
Starlink satellite network communications
Although the mainland has long realized the connection between villages and villages and permanent residents through the Internet, compared with the densely populated eastern and western deserts, northern grasslands, northeast forest farms, and snow-capped mountains, these vast and sparsely populated areas, whether mobile or telecommunications, have no confidence in achieving full coverage, and still stay on the "communication all rely on shouting", which is really abuse. For example, a group of climbers was hit by an avalanche, and without a communication base station, it was difficult for rescuers to reach the scene in time and accurately. Satellite Internet is not important, satellite phones are the most convenient communication tool on Antarctica research ships, so when mobile communications on the ground "can't go anywhere", people will look up at the sky.
This time, under the leadership of the State-owned Assets Supervision and Administration Commission, the establishment of China Satellite Network Group Co., Ltd. can undoubtedly give full play to the advantages of state-owned enterprises, that is, to twist the people's hearts into a rope, focus on the mission, and become bigger and stronger. Because, long before the "rope" was tightened, the continent began experimenting with satellite constellations, which had attractive names such as geese, clouds, the Milky Way, and so on. Instead of trumpeting themselves outside the professional world, these companies quietly launched groundbreaking satellites and tested them again and again. Today, the SASAC has moved in, and the formerly fragmented satellite network will be integrated into a new ubiquitous satellite network under unified planning.

Here, some viewers may wonder if the continent will start too late because of Musk's Starlink program, which has been launched more than 1500 times. It's not too late. The Starlink project sounds like something out of a science fiction movie, but in reality, satellite communications will play a long-term supporting role in the communications arena. In terms of information transmission, if "StarLink" uses as much as 5G, the gap in hardware resources will cause the transmission speed of the former to be only one thousandth of the latter.
Data released by the Ministry of Industry and Information Technology shows that in the next few years, 5G will be widely used, and it is expected that there will be 446446744744 number of base stations, and the tens of thousands of satellites planned by Xinglian are simply not enough to cover 5G. In addition, in the real world, satellite communications must have a receiving antenna capable of receiving signals at 20Ghz frequencies, and 5G signals will inevitably pass through that spectrum, potentially causing mutual interference.
Viewers can measure the difference between satellite communications with a latency of 500 milliseconds, video loaded in minutes, and 5G with a 1-millisecond delay that the human eye does not perceive at all. The former is $99 per month, the latter is a pillar of the state and can be installed for free. Now that these two signals are "fighting", which one do you prefer?
Most importantly, satellites are resource-constrained systems. The universe is vast, but with technology, there is a limit to how many orbits you can orbit. Musk certainly wants as many satellites into orbit as possible, but because of the prime location, he can't go alone like a businessman. This is where the advantages of the continent lie. There are many satellite communications companies in the United States, and there is not much room for too many homogeneous competing constellations, and by the time businessmen find ways to eliminate their opponents, state-led plans have long been a holistic approach.
In terms of maintenance, manually repairing 5G base stations is cheaper than replacing satellites, and launching satellites to a designated location and completing the replacement of old and new satellites is more difficult than engineers climbing up to the base station. At present, the scrap rate of Starlink's satellites is 3%, that is, nearly 50 satellites, which have become space junk, can never be recycled, and are quietly used as dangerous substances.
If satellite communications have so many drawbacks, why would the mainland launch its own starlink program? The answer is simple. The satellite Internet is not a subversion, nor is it a replacement for terrestrial cellular communication networks, they have their own main track, and to meet the needs of different user groups, the relationship between the two must be complementary, on the mainland. Densely populated areas such as cities are the base camp for 5G, while remote areas such as forests, oceans, and deserts are the base camps for satellite communications.
It can be said that the complementarity of the two means of communication has led to the effect of "one plus one". As the doctor mentioned before, the orbit of the satellite is limited, if we do not have our own "star chain", the sky will be someone else's, Musk's slogan is the global dead-end service is as great a threat as the world he sees. As a result, more and more countries are starting to be vigilant and take corresponding precautions, after all, who has no little secrets that musk can invade his privacy at any time and anywhere? It's far from it. Think of prism gates, where the United States is spying on other countries.
Businessman Musk's Starlink program, in addition to making the country's privacy security "uncomfortable", has also had some negative impact on other businesses and the country's aerospace industry. We just talked about 5G and satellite communications interfering with each other's signals, and that's what happened. Starlink had just taken off from the ground, and many companies were receiving erratic signals. SpaceX, a near-monopoly company, made Musk $50 million at the start of the project. In response, other communications companies have even formed anti-Starlink alliances.
To make matters worse, Musk relies heavily on small satellites to keep costs down, and when they are in a vantage point and other countries want to launch again, they have to wait for SpaceX to agree to shoot them down. Existing satellites will no longer be safe after satellite launches become "needles in the haystacks".
Musk Starlink Program
In 2019, the European Space Agency plans to launch a new satellite to replace its technologically backward meteorological observation satellite, but in the event of Fengshen's rise, it collided with the "Starlink 44" European Space Agency as designed, had to temporarily change orbit, and silently undertook additional launch and maintenance costs. What happened to the European Space Agency seems to be a wake-up call for other companies or countries, and if you just watch Musk's launch without taking action, it's like watching a movie and buying the same tickets, with people sitting in the middle and huddled around a corner.
So, is Musk's Starlink program an exclusive plan for Scorpion Tail? Of course not, as early as 2015, China Aerospace Science and Industry Group and China Aerospace Science and Industry Group began to build their own low-orbit satellite communication projects - the Hongyan Constellation " system and the Red Cloud Project. Compared with Musk's 42,000 satellites, our other satellite, the "small target" of the Internet of Things project, is only 80, and the first phase of the project has been completed in 2020, and after the completion of the entire system, it can not only meet the wishes of the "Belt and Road", but also provide a certain degree of security for our sky.
Meanwhile, with the massive commercialization of 5G, with the evolutionary frequency at which mobile communications are updated every 10 years, the researchers will add 6G to their daily task list. The vision of 6G development is very beautiful, in addition to building a ground communication network, it is also necessary to integrate satellite communication networks and deep-sea ocean networks, and promote the development of barrier-free global communications in the nine days of the moon, September, five oceans to catch turtles, and five seas. Therefore, now the mainland promotes the development of satellite communications, echoes and collaborates with 5G, and can also provide data for 6G research and lay a solid theoretical foundation.
Upcoming 6G
Therefore, building "StarLink" and deploying "Internet +" is more like China's infrastructure construction than the so-called "Musk Bidding", which is an important step towards the maturity of China's aerospace industry chain, and it is also a necessary measure to protect satellite orbit resources under the interference of Starlink. The construction of the mainland satellite communication system has the same motivation as the construction of the Beidou satellite navigation system, we have independent intellectual property rights and privacy rights, no matter what happens in the future, we have cards to play, will not be seen by others, will not be controlled by others, behind the huge challenges, there are greater opportunities.
