The speed of astronauts using their mobile phones on the space station is comparable to 5G. How does the Internet enter the space station?

Communication between the space station and the ground mainly relies on ground measurement and control stations, data transmission receiving stations and Skylink relay satellites.

China, Russia and other countries are planning lunar missions: it is estimated that about 100 spacecraft or spacecraft will reach the moon by 2030. Of course not all will come to fruition, but this will only delay the almost inevitable end result: the establishment of inhabited bases and a permanent human presence on Earth's natural satellite. The task will not be easy: the staff will need a reliable and comfortable place to live, with all the due benefits of civilization.

The communication between them was far from the last. In our country, the communication between the space station and the ground mainly relies on ground measurement and control stations, data transmission receiving stations and sky link relay satellites. Among them, the sky link relay satellites can ensure uninterrupted communication. To put it simply, to realize network interconnection between the space station and the ground, we need to rely on artificial satellites and other auxiliary equipment. However, SpaceX founder Musk once mentioned a plan to launch about 40,000 artificial satellites. Through artificial satellites, all Internet users on the earth can communicate with each other on WiFi at any time, thereby saving a lot of traffic costs.

Although Musk’s Starlink project can benefit mankind, it unfortunately has some flaws, that is, so many satellites orbiting the earth will hinder the observation of the starry sky. Careful netizens discovered that astronauts are equipped with smartphones and can make normal calls and video communications. The data transmission rate is similar to that on the ground, using Huawei's p30. Later, official news confirmed that it was a Huawei P30 mobile phone, which was indeed brought to the Chinese Space Station by our astronauts to upgrade to the Hongmeng system.

In addition, according to official documents, the wireless network technology of the space station uses Huawei's 5G technology. The smart home solution of the space station is the same as Huawei's Hongmeng system smart home solution, both of which are implemented through the Hongmeng system platform. The "Internet of Everything". Astronauts can only adjust cabin lighting and other equipment through mobile apps. In fact, Chinese astronauts are not only equipped with Huawei smartphones, but Huawei also provides a variety of technical support, including a data sharing service platform.
