The smartphone market, which has been silent for a long time, has attracted much attention because of the "Shangxin" satellite communication function. On June 6, Huawei released the Huawei mate 50 series, the first popular smartphone that supports Beidou satellite communication. The day before, Xingji times, a subsidiary of Geely, which acquired 79.09% of Meizu technology, announced that it would launch the world's first consumer mobile phone directly connected to low orbit satellites. According to media reports, the upcoming iPhone 14 series will also support satellite communication functions. What's the use of mobile phone supporting satellite communication? What are the pros and cons? Will consumers pay more for this? According to Yu Chengdong, CEO of Huawei consumer business, Huawei mate 50 series can still send messages through Changlian app if there is no network signal on the ground, such as in deserts, seas, mountains and so on. In addition, through the Beidou satellite message, Huawei mate 50 series can also generate a trajectory with one click and send it out, so that rescue personnel can obtain the location in time and accurately. The reporter noticed that at the press conference, Yu Chengdong did not give much introduction to this brand-new communication technology that he previously called "breaking the sky upward". In fact, satellite communication is not a new technology. It can even be said that it is quite mature and widely used. However, it is relatively new to integrate this technology into commercial mobile phones. Satellite communication, that is, sending and receiving information through communication satellites in the sky, such as text and voice, is often used in geological exploration, ocean transportation, forest patrol and other special fields and people. The communication efficiency is relatively low and the price is expensive. Satellite communication also requires equipment, such as high antenna power and strong anti-interference, so common satellite phones are basically equipped with a very long antenna, and generally can only be used in outdoor scenes. The application of satellite communication technology to smart phones can be said to make up for the lack of signal network coverage of operators. For example, in "signal desert" areas such as oceans and forests, satellite communication can enable mobile phones to make calls and send text messages without becoming a "brick". Is satellite communication on mobile phone difficult? The day before the release of Huawei mate 50 series, Geely's Xingji times company also announced that it would launch the world's first consumer grade mobile phone directly connected to low orbit satellites, so that people can "never lose touch". Earlier, Guo Mingyu, an analyst at Tianfeng international, broke the news that Apple's iPhone 14 series, which will be released on September 8, will also support the satellite communication function and complete the hardware test of the function before the press conference. According to media reports, Google also announced recently that the next generation Android system will also support mobile satellite communication functions, and the Android 14 developer preview is expected to be launched in March 2023. This means that all Android phones equipped with the Android 14 system are expected to support this technology in the future. Then, why do many mobile phone manufacturers announce to "update" the technology at this time? Is it difficult to connect mobile phones to satellite communications? What are the pros and cons? Fu Liang, a telecom analyst, told reporters that satellite communication technology is relatively mature, and it is practical to integrate this technology into mobile terminals, but both
