However, a Huawei PR officer told the Global Times on Saturday that he has not received such information. China Mobile declined to answer the Global Times when asked. Ma Jihua, a senior analyst in the tech industry in Beijing, told the Global Times that the move to use satellites is natural as Huawei pushes up the layout of 6G networks, 50 times faster than 5G. Compared to building 5G networks that rely on base stations to transmit signals, 6G networks transmit higher frequencies, needing to use satellites for communication instead of base stations where there will be low penetration capacity, Ma explain. Illustration. Huawei’s rotating chairman, Xu Zhijun, announced at Huawei’s global analysts conference earlier this month that the Chinese tech giant will launch its 6G network by 2030 at the same time soon. Release of 6G white paper to explain what is 6G industry. In fact, in 2019, Huawei proposed launching more than 10,000 small satellites to provide 6G services worldwide, during the global 6G summit. China has made the biggest 5G footprint worldwide and is likely to go further in 6G development with efforts from giant Huawei, which has 5G technology outperformed. rivals and also leads in research and development 6G despite the US causing difficulties. According to Ma Jihua, the potential of 6G technologies is something no government or company can ignore despite the fact that it is still in the early stages of research and development. Satellite communication has shown increasing importance since last year with the proposal of new infrastructure. Ma Jihua also noted: “We need to know how to communicate in a satellite constellation as the country pushes forward with technology development along with Huawei’s new 6G satellite moves even though both use satellites.” China’s satellite constellation, such as the current projects in which Hongyun and Hongyan have been involved, aims to make online access available to residents and businesses in remote and remote areas in China. While the 6G satellite is used more widely for testing and data availability in popular metropolitan areas, Ma added. It is known that at the end of last year, China launched the world’s first 6G test satellite from the Taiyuan Satellite Launch Center in Shanxi Province, North China, marking a breakthrough in public discovery. terahertz space communication technology of China.

Qian was born when the last Chinese dynasty was about to be replaced by a republic. From a young age, Qian was gifted and eventually, he graduated with distinction from Shanghai Jiaotong University, winning a rare scholarship from Massachusetts Institute of Technology (MIT) in America. Qian Xuesen (Precursor of Ginseng) From MIT, Qian moved to the California Institute of Technology (Caltech), studying under one of the most influential Hungarian aeronautical engineers named Theodore von Karman. There Qian shares his office with another famous scientist, Frank Malina, who is a key member of a small group of innovators known as the Suicide Squad. Fraser MacDonald, author of “Escape from Earth: A Secret History of the Space Rocket”, said the group earned the nickname for its efforts. of them in building a rocket on campus and because of some of their experiments with volatile chemicals. At that time, rocket science was considered by MacDonald as “a tool of reelers and fantasies. No one takes it seriously – no mathematic engineer has risked their reputation in saying this is the future. But, that quickly changed when World War 2 began. The “suicide squad” attracted the attention of the US military and was funded for research on a jet-assisted takeoff method, where the boosters were attached to the wings of aircraft so they could fly. overhead from short runways. Military funding also helped establish the Jet Propulsion Laboratory (JPL) in 1943, with its director, Theodore von Karman. Qian, along with Frank Malina, is at the center of the project. Qian is a Chinese citizen but the ROC is an ally of America, so “there is no great doubt that a Chinese scientist is at the heart of America’s space effort,” said Fraser Macdonald. Qian is licensed to work in the classified weapons research department and even served on the US Government Scientific Advisory Board. At the end of the war, Qian was one of the foremost experts in jet engines and was sent with Theodore von Karman on an extraordinary mission to Germany, serving as a temporary lieutenant colonel. Their goal was to interview Nazi engineers, including Wernher von Braun, Germany’s top missile scientist. America wants to find out exactly what the Germans know. But, by the end of the decade, Qian’s sparkling career in America suddenly stopped. In China, Chairman Mao Zedong proclaimed the founding of the People’s Republic of China in 1949. Meanwhile, a new JPL director believed there was a spy group at the laboratory and shared the suspicions. about a number of employees with the FBI. It is in this atmosphere that the FBI accuses Qian, Frank Malina and others of threats to national security. The allegations against Qian are based on 1938 US Communist Party documents that show Qian attended a social gathering that the FBI suspected was a meeting of the Communist Party of Pasadena. Zuoyue Wang, a history professor at California State Polytechnic University, claims there is no evidence that Qian ever spied for China or was an intelligence agent while he lived in the US. However, Qian was stripped of his security passport and placed under house arrest. Caltech colleagues, including Theodore von Karman, wrote to the government pleading for Qian’s innocence but to no avail. In 1955, after Qian was under house arrest for five years, President Eisenhower decided to expel him to China. The scientist left by boat with his wife and two children born in America. Qian told reporters he would never set foot in America again and that he kept his promise. When he arrived in the US, Qian had very little knowledge of rocket science. But, 15 years later, he oversaw the launch of the first Chinese satellite into space. For decades, Qian trained a new generation of scientists, and his work laid the foundation for China to send people to the Moon. While most Americans know nothing about Qian and his role in the US space program, Tianyu Fang said many Chinese Americans and Chinese students in the US knew about him, why he had to leave. and they see similarities today. “US relations with China have become so much worse that they know they could be suspected of being like Qian’s generation,” Fang commented. In Fraser MacDonald’s view, Qian’s story is a warning about what happens when knowledge shredding. “The whole story of American science is that it was driven by people from outside.” MacDonald believes that JPL’s contribution to the American space program was far ignored compared to Wernher von Braun and other German scientists, who were secretly arriving in America shortly after von Karman and Qian’s visit. Braun was once a Nazi but his achievements are recognized. Whereas the achievements of Qian and others from the JPL are not. Qian’s life lasted for nearly a century. During that time, China has grown from an uneconomical country into a superpower on Earth and in space. Qian is part of that transformation. But, Qian’s story can also be a great American one – where talent can flourish wherever talent is found.

SpaceX denied claims that the Starlink and OneWeb satellites almost collided In a filing submitted to the US Federal Communications Commission (FCC) after a meeting between representatives of SpaceX, OneWeb and FCC, SpaceX said that, in fact, the probability of a collision never exceeds the allowed threshold and the satellite will not be able to collide even if it is active. They have also corrected records regarding recent press releases regarding the physical coordination between SpaceX and OneWeb. Meeting between the parties took place the day after the flyer The Wall Street Journal published an article titled “Elon Musk’s satellite Internet project is too risky,” in which OneWeb made allegations that the Starlink satellites had approached other satellites alarmingly two. times in the past two years, including the last which took place on April 2, when a satellite Starlink Send a request to a OneWeb satellite to take collision avoidance measures. Sheet The Wall Street Journal quoted Chris McLaughlin, OneWeb’s director of legal and government relations, saying, “While working with OneWeb, SpaceX disabled the automated collision avoidance system supported by artificial intelligence (AI) to allow OneWeb to steer its satellite away from other satellites. It is unclear exactly why SpaceX disables the collision avoidance system when the Starlink satellite is within 57 meters from the opponent’s satellite. SpaceX has not yet commented on this issue. In a filing filed with the FCC on April 21, SpaceX said: “OneWeb recently made clear and inaccurate statements to the media about recent coordination. Specifically, Mr. McLaughlin of OneWeb told the newspaper Wall Street Journal that SpaceX has powered off the automatic satellite collision avoidance system. In reality, however, SpaceX and OneWeb have worked well together on a technical level. And OneWeb itself has asked SpaceX to temporarily turn off the AI ​​system to allow them to control the satellite as agreed by the parties. SpaceX’s automatic collision avoidance system has been and still works well at all times. According to SpaceX, OneWeb admitted wrongly and offered to withdraw its false statements during the meeting with SpaceX and FCC. SpaceX expressed its disappointment to the FCC that OneWeb officials chose to make public false information about the coordination’s plight. Successful coordination depends on trust and transparency among satellite operators. Also in the filing to the FCC, SpaceX confirmed that the possibility of collisions between satellites is very small. Other data also showed that “probability of collisions between satellites is below the permitted threshold and continues to decrease”. OneWeb launched satellite launch operations on April 3, and the satellites are eventually more than 1,000 meters apart. The probability of a collision happening is extremely small.

The technology giants like Amazon, SpaceX, OneWeb continuously pour money to invest in satellite Internet. Photo: TechCrunch In recent years, satellite broadband is becoming an increasingly popular way to connect to the Internet. Major space companies are also in the race to build ultra-high-speed Internet services through orbiting satellites. Now, the field is forming a model similar to the “Seven Warring Heroes”. The companies are all moving towards a common goal: competing to be the biggest brand in broadband satellite and SpaceX’s position with Starlink dominance is being challenged. SpaceX’s Starlink project SpaceX boss – Elon Musk Of all the companies, SpaceX is the one involved with the most satellite launches. Its Starlink project has more than 1,350 satellites in orbit and plans to launch 42,000 satellites by mid-2027. Eventually, SpaceX hopes to have thousands of satellites around the Earth to establish a global network. Starlink’s Beta “Better than Nothing” was launched last October and attracted more than 10,000 users in six different countries. Starlink’s business model connects customers directly with satellites without the intervention of telecom companies between the two parties. Users register for Starlink service through the website. Once the order is accepted, Starlink will send the hardware set to the customer, which includes a tripod, WiFi router and satellite antenna. Monthly subscription fee is $ 99, and maximum download speed can reach 210 Mbps. Starlink is expanding rapidly and plans to install antennas on vehicles and connect them to satellite networks. According to the test of Internet analytics service developer Ookla, the download speed when using SpaceX’s satellite Internet is 95% faster than the normal Internet in the United States. Project Kuiper from Amazon The Amazon project is named Kuiper In 2018, Amazon’s Kuiper Project was revealed. At that time, government documents showed that the tech giant was working to build global space-based Internet services. The goal of the project is to launch 3236 satellites into a 630 km long orbit, very close to the 550 km altitude of the Starlink satellite. In January of this year, the US Federal Communications Commission approved the Kuiper Project to launch Amazon satellites into space before July 2029, and connect them to antennas on Earth to provide translation. Internet service. As of July 30, 2026, 50% of the project’s satellites will operate. Like Elon Musk, Jeff Bezos, the boss of Amazon, also owns a private rocket and space service company called Blue Orgin. Although no specific plans have been announced, the company is believed to be in charge of bringing the Kuiper satellite into orbit. OneWeb The Soyuz-2.1b carrier missile carries 36 OneWeb satellites that take off from the launch pad of the Vostocini launch pad. OneWeb is a UK owned broadband satellite provider. It currently has 146 satellites in orbit, 1,200 km from the ground and plans to launch a total of 648 satellites to provide global Internet service. In November last year, the company got out of bankruptcy thanks to the British government and India’s Bharti Group. OneWeb hopes to provide Internet services to the entire UK by June. Its latest service will cover the highest latitudes in the world, including Alaska, Canada, Greenland, Russia and Nordic countries. This British company provides a B2B model, provides satellite Internet to telecom companies, then the telecom companies deliver services to customers. Both SpaceX and OneWeb launched satellites into space on March 25, clearly showing a race between the world’s two leading powers in space technology. Hughes Net Satellite team Hughes Jupiter 2 Hughes Net is the largest satellite Internet provider in the United States. It relies on geostationary orbit (GEO) satellites 36,210 km away to transmit the Internet back to earth. The main difference between a satellite operating in low Earth Orbit (LEO) and a geostationary satellite is that GEO satellites can cause delays in video calls and public calls. other technology. However, the GEO satellites are in a fixed position, so unlike LEO satellites, they will not travel in orbit but target a specific area. The Hughes Network has more than 1.5 million users and six satellites in orbit, covering different areas of North America, South America and Canada, including Mexico, Brazil and Chile. The last satellite that Hughes launched was in June 2018 and its goal is to put another satellite, called Jupiter 3, into orbit by the second half of 2022. It is said that this will be a commercial satellite. the biggest ever. Hughes’ satellite service costs range from $ 59.99 to $ 149.99 per month and download speeds of 25Mbps. The kit is priced at $ 249.99, and the installation costs $ 199. The company also offers public WiFi hotspots for rural Latin America for people who cannot afford subscription fees. Telesat Daniel Goldberg, CEO and President of Telesat, Canada’s satellite operator Telesat has 15 GEO satellites at an altitude of 35,000 km above Earth. The company also plans to build an LEO Internet called “LightSpeed”. The first 298 satellites built by Thales Alenia Space are scheduled to launch in early 2023 and provide global services by 2024. According to reports, Goldberg confirmed at the 2021 LEO Satellite Digital Forum on April 6 that the LightSpeed ​​project would cost $ 5 billion. This is much cheaper than the projects of SpaceX and Amazon, which are more than $ 10 billion. Goldberg recently stated that Telesat has the best pricing in the market. In 2019, Telesat signed a launch agreement with Blue Origin to use New Glenn rockets to send LEO satellites into orbit. David Wendling, Telesat’s chief technology officer, revealed that the company has three other startups underway. ViaSat ViaSat application on smartphone ViaSat is headquartered in California, USA, operates five GEO satellites at an altitude of about 35,000 km from the Earth’s surface. The company will put three extremely powerful GEO satellites into orbit by the beginning of 2022 and achieve globalization goals until 2023. ViaSat also plans to put 288 satellites into orbit LEO by 2026. ViaSat executive chairman and co-founder Mark Dankberg said the GEO and LEO satellites would complement each other. ViaSat is working hard to create a “multi-orbit satellite Internet where users can seamlessly use GEO satellites and LEO satellites.” In December 2020, Viasat asked the FCC to study Starlink’s potential environmental impact. In response, Musk wrote on Twitter: “Obviously, Starlink is a ‘threat’ to Viasat’s profits.” Eutelsat Eutelsat is Europe’s satellite operator with 39 GEO satellites at an altitude of 46,000 km. The company now provides Internet services to the regions of Europe, Africa and the Middle East, and plans to launch another satellite called Konnect VHTS to cover the rest of Europe. Michel Azibert, Executive Vice President of Eutelsat, said: “Konnect VHTS will change the rules of the game and allow Eutelsat to seamlessly deliver powerful Internet services to users at prices comparable to the above operators. ground.” Azibert says Eutelsat’s satellite service “is much lower than Starlink, very well suited to the rural markets we’re targeting in Europe, the Middle East and Africa.” Eutelsat was founded in 1977 and launched its first satellite in 1983.
