Different connection methods:
1. Satellite communication uses data center - core network - ground station - communication satellite - transmission between satellites - receiving terminal;
(Terminal can be carried on cars, planes, ships) Mobile terminals generally can not receive satellite communications;
That is to say, if you want to use satellite communications, you need to buy a terminal that can accept satellite communications.

2. 5G communication uses data center - core aggregation access - base station AAU- mobile phone;
Now the base station directional antenna is used to receive information for transmission, and the base stations of major communication companies also cover a very comprehensive.

Different communication speeds:
1. 5G is characterized by high reliability and low delay, which can serve users with 1ms low delay based on the base station;
2, but the satellite communication transmission light ground-air-ground speed also needs 3.6ms, coupled with server and satellite transmission delay, is expected to reach more than 20ms and 5G communication speed is not comparable.
Satellite communication and 5G are two different communication technologies. Satellite communication is the transmission of signals through satellites and has a wide coverage, which is suitable for remote areas and places such as oceans that cannot be covered. 5G is a wireless communication technology that transmits signals through base stations, has higher transmission speeds and lower latency, and is suitable for urban and densely populated areas.
The cost of satellite communication is high, and the construction and maintenance cost of 5G is relatively low. In addition, the signal transmission distance of satellite communications is longer, while the signal transmission distance of 5G is shorter. To sum up, there are obvious differences between satellite communications and 5G in terms of coverage, cost and transmission distance.
