"Huawei leads again: China Mobile completed a satellite Internet test with a speed of 5 Mbps"！
The Internet is an important part of modern society, and its form is changing due to the progress of science and technology. Satellite network is a new technology that has emerged in recent years, and it is gradually coming into our sight.
In this regard, Huawei has once again proved its leading position in science and technology through the "Star Network" experiment with China Mobile.
China Mobile Communications Research Institute announced some time ago that the company has carried out in-vehicle mode tests with its partner companies, and jointly developed the in-car network kernel and"Star element system"。One of them is Huawei, and one is Huawei's Mate60 as the final product.
This technological breakthrough not only marks an important step forward for China to go online on satellites, but also indicates that most ordinary mobile** will be able to use "satellite Internet" in the future.
So, where do you need to focus on this exam?
i.Space Central Network: An important piece of equipment for satellite networks around the Earth.
As the most basic Internet equipment for low-earth orbit satellites, the spaceborne communication system is responsible for the transmission of information in orbit. It can quickly and efficiently process data on the ground and transmit it to all parts of the world.
The satellite backbone network jointly developed by Huawei and China Mobile Research Institute (CMRI) has high spatial stability and reliable performance.
2. Technology leadership: SBA solution for 5G core network.
According to the specific needs of aerospace applications, China Mobile takes SBA 5G as the research object to study a highly reliable and flexible on-orbit reconfigurable software and hardware system. The system should not only make full use of the characteristics of the space environment, but also take into account both scalability and scalability.
Taking China as an example, this project uses domestic materials and combines domestic Linux systems to ensure China's scientific and technological support in this regard.
iii.Large-scale test: Satellites are carried out at an altitude of 550 km**.
Huawei and China Mobile Research Institute have conducted a number of experiments on the spaceborne backbone network to test its ability to work under various communication conditions. They not only carried out the satellite at an altitude of 550 km, but also built an end-to-end connection from the test terminal, ground-based 5 G base station, ground-based signal gateway station, spaceborne radio transmitter and other terminals to the spaceborne backbone network.
On this basis, the feasibility study of high-dynamic, large-delay narrowband cable and wireless low-earth orbit satellite communication is carried out.
Outstanding performance: 5 Mbps** speed.
Through practical tests, the system has good network characteristics. The research results of the project will achieve a downlink of 5 Mbps, an uplink of 1 Mbps, a spaceborne delay of 230 Mbps and a spaceborne delay of 1 ms.
v.Industry effect: Broadband brings a large number of mobile and industrial terminals.
In the future, most mobile phone users will be able to use mobile phones to access the Internet, and it will be more convenient and faster. Whether they are in a distant place, or by plane, ship or other means of transportation, people can access the Internet at any time and anywhere to get the information and services they need.
Without the technological innovation and breakthroughs of other companies such as Huawei, this dream would not have been possible. Huawei is a leading enterprise in China's telecommunications industry and has always been committed to providing high-quality communications equipment and services to customers around the world.
With its strong scientific and technological strength and independent R&D advantages, Huawei has once again proven its leading role in the satellite network industry. The cooperation with China Mobile Communications Research Institute will effectively promote the construction of satellite Internet in China, and will enable more people to enjoy more convenient and efficient Internet services.
Epilogue. The smooth development of Huawei and China Mobile Research Institute will strongly promote the construction of China's "satellite network". We can foresee that with the development and extension of science and technology, the future satellite network will become more convenient and effective.
However, in the process of development, there are also many challenges and opportunities. To this end, we must continue to strengthen research and development to support the development and application of China's satellite network.
