IT House reported on September 12 that Huawei Mate 60 Pro / Pro+ series of mobile phones were quietly launched recently, which immediately triggered a buying spree. The two new phones have launched the satellite phone function, with the corresponding services of the operator, you can make phone calls without a base station signal.

Following Huawei's Mate60 Pro, other domestic mobile phone manufacturers will also support satellite calls in their products by the end of this year, according to Science and Technology Innovation Board Daily.

According to people familiar with the matter, the domestic Volkswagen smartphone directly connected to the satellite function, there are a number of original technological breakthroughs, mainly developed by China Telecom and Huawei. There are still some technical difficulties such as antenna miniaturization in satellite mobile phones as a whole. In addition, the concurrent communication capacity of satellite calls is also limited, so it is difficult to compare with the capacity of ground cellular communication.

He believes that considering that more mobile phone manufacturers will provide terminal access in the future, there may be an increase in the number of people using satellite calls at the same time.

People in the industry chain also said that on the one hand, satellite communications services will monitor the utilization rate of mobile satellite calls to determine whether to expand capacity; on the other hand, various agencies are also increasing satellite launches, and the problem of communication capacity is expected to be resolved in the future. The person further said that there is a great demand for smartphones with satellite calls, but it is still limited by production capacity.

According to IT House's previous report, China Telecom has taken the lead in launching the "mobile directly connected satellite" service, which allows users to install directly connected satellite services on the basis of their ordinary mobile phone card packages. All telecom packages can be handled without changing cards or numbers, and the directly connected satellite function can be used immediately.

China Telecom said that the mobile phone direct connection satellite service is for China Telecom to give full play to the exclusive operational advantages of Tiantong-1 satellite, support ground-based 4G, 5G and Tiantong-1 satellite communication capabilities, and achieve "5G + satellite" integrated communications. The coverage area of Guangtiantong satellite signal covers all of China's territory and territorial sea. Terminals that can use satellite direct connection function need to support satellite direct connection service.
