In 2020, the United States launched the unlimited traceability mechanism, when some people believed that after leaving Huawei's 5G telecom equipment, Musk's StarLink could cover the region as an alternative.

In the past 3 years, the number of StarLink in the United States has approached 10,000, and it provides services in the United States, Europe and other regions, and the user population has reached one million. In the future, SpaceX aims to expand the number of people it serves to 9 million.

Replacing 5G communication technology with StarLink sounds very sci-fi, but the reality is very bone-chilling. According to the information released by SpaceX, the main communication bands of Starlink satellites are KU, KA and V, and their operating frequencies are 10.7~80Ghz. At present, the 5G millimeter wave base station built in the United States will also have an operating frequency of about 30Ghs.

In terms of the density and area of service users, a satellite is much larger than a base station. A starlink can serve the Shanghai area, and it is obviously not possible to change to a base station, unless the low frequency band is used. However, satellites also have their own shortcomings, high operating frequency, weak signal penetration ability, and cannot provide services to users in cities and buildings.

5G base stations can not only provide high-quality communication technology, but also enable indoor and underground garage users to receive phone calls and access the Internet without obstacles. Judging from the current performance of StarLink, it can only provide services to the ground fixed antenna, and if it is moved and cross-regional Internet access, it will violate the starlink service usage rules.

Starlink has its own place of use, users live in deserts, islands with no obstacles to block the sky, or users of ships and planes on the high seas, which is a blessing. If it is a city, the value of StarLink will be discounted, and the United States will use it as a substitute for 5G telecom base stations, which will make it pick up a sesame seed and throw a watermelon.
