Satellite phone can be described as the killer function of Huawei Mate60 Pro and other models, and consumers pay close attention to it. However, according to CNMO, the implementation of satellite call function is not an easy task.

A blogger revealed that Telecom had visited a number of mobile phone manufacturers to seek cooperation in satellite calls, but in the end only Huawei took over the difficult task.

Recently, an aviation blogger revealed (the news may come from the 2023 China Radio Conference) that after Telecom Satcom (China Telecom Group Satellite Communications Co., Ltd.) had the idea of connecting mobile phones directly to satellites, he visited many mobile phone manufacturers and experts. but they all said it was too difficult and impossible, and in the end only Huawei accepted the cooperation.

The blogger also revealed more details. It is reported that the Tiantong-1 series of satellites cooperated by Huawei was developed by the Fifth Institute of Aerospace Science and Technology, with a total of three, and Tiantong's commercial operation is only the responsibility of China Telecom Group Satellite Communications Co., Ltd. China Satcom is only a listed company under the Aerospace Science and Technology Group. Huawei Mate60 Pro has achieved mobile phone direct connection to satellite, Telecom and Huawei are very powerful, and the Fifth Academy of Aerospace Science and Technology, as a satellite developer, has quietly done a lot of cooperation in this process, but also very powerful.

According to experts, there are many difficulties in mobile phone directly connected satellite technology. For example, on the chip side, satellite baseband chips are often too large, energy consumption is very high, if directly miniaturized, it will not be easy to dissipate heat. Therefore, the solution is to improve the process, integrate baseband, radio frequency and storage, and adopt new technologies such as intermittent transceiver to reduce energy consumption.
