Huawei's Mate 60 Pro mobile phone listed in advance is a bit subversive to Xiaobian's cognition. In the past two days, Huawei, which has been sanctioned by the United States, carefully selected the moment of the US Secretary of Commerce to visit China, and launched a new flagship mobile phone, which is quite a bit of the taste of the J-20 frontal Gates, and it is Wang Fried as soon as it is shot, whether it is the first pure domestic CPU of the 7nm process, Hongmeng 4.0, or 5G + network, crushing camera performance, all witness the historical moment of pure domestic mobile phones. However, the most attractive thing is its ability to support satellite voice calls.
You know, Huawei Mate60 Pro packaging box is written on the satellite mobile terminal, not a traditional digital mobile phone, obviously, it is certified as a satellite mobile terminal. Support for satellite voice calls is Huawei's Mate60 Pro's biggest innovation, which is said to use the 36,000-kilometer Tiantong high-orbit communication satellite, which can not only make and receive satellite calls when there is no ground network, but also freely edit satellite messages and select multiple location information to generate trajectory maps.
The certification passed is a satellite mobile terminal
However, in our traditional perception, mobile phones are directly connected to satellites, which is somewhat fanciful. The orbital altitude of SpaceX's "Starlink" satellite is only five or six hundred kilometers, and the antenna of the communication terminal is as large as a wok, and it also uses phased array beamforming to increase the gain, so how does Huawei Mate60 Pro directly connect to a satellite with an orbital altitude of 36,000 kilometers with a small mobile phone? Can your phone find a signal 36,000 kilometers away?
Starlink is currently unable to do direct mobile phone connection
The answer is actually known to many people, first of all, there are indeed phones that can directly connect to satellites, and the volume has been similar to ordinary mobile phones, which is not a rare thing, but they all have a long antenna exposed. What Huawei Mate60 Pro does is to overcome this antenna barrier and implant the antenna inside the mobile phone. Of course, implanting the antenna of the satellite phone into the mobile phone is not as simple as imagined, because in addition to passing the antenna pass, it also has to pass the processor pass, and it is necessary to add a high-power PA.
The selling price of a regular satellite phone
However, the maximum transmission power of general satellite phones is more than 2 watts, and the wireless transmission power of mainland civilian consumer electronic products, FDD limit is up to 200 milliwatts, TDD limit is up to 400 milliwatts, Huawei Mate60 Pro in satellite communication, whether the transmission power exceeds the limit of civilian consumer electronic products, the most important thing is that there will be radiation?
There are currently only three high-orbit communication satellites in Tiantong
In fact, Huawei Mate60 Pro direct satellite is not carried out all the time, only when you need to choose to open, will increase the power, this time life is far more important than radiation. In addition, satellite phones have been invented for decades, there are many high-frequency users, but no one died because of radiation, and even the group of people who played routers specifically went to brush the firmware, unlock the limit, and increase the power N times, much more powerful than satellite phones, and no one was killed by radiation.
Since as an ordinary person, you don't often use satellite phones, so Huawei Mate60 Pro supports satellite voice calls, is it just a gimmick? In fact, although the mobile phone-sized satellite phone can be purchased directly online, the price is often more than 10,000 yuan, and Huawei Mate60 Pro as long as less than 7,000 yuan, it comes with one, which can be described as a great value, even if this function is idle, its price is not higher than the flagship of other brands.
And for the group in need, not everyone knows to go in advance to buy a satellite phone, Huawei Mate60 Pro directly supports satellite voice calls in the form of mobile phones, to the extent that everyone is now inseparable from the mobile phone, it is equivalent to a cheap satellite phone, if it can be listed early, 3 people who crossed Lop Nor some time ago, may be able to avoid death, what do you think?
