Beidou Zhongxing Group and Huawei jointly developed a Beidou Huawei mobile phone with the following special functions:
1, calling is free. Beidou Huawei mobile phone uses our own card, not the mobile phone cards of China Mobile, China Telecom and China Unicom. (In the past, when watching foreign blockbusters, satellite phones often appeared like this. ) Because the Beidou Huawei mobile phone itself is a satellite phone.
Internet access is free. This may be a little difficult for some friends to understand, so let's explain it. Like city people, we have to pay for digital TV, right? But in some remote mountain villages, it is impossible to watch digital TV or even closed-circuit TV. So, as long as there is a pot cover, you can watch a lot of TV stations, right? This is satellite TV. Then Beidou mobile phone is like this, there is no mobile telecom Unicom, but it can also surf the Internet, and it is free.
3, the network speed is super fast. Everyone knows that the high-speed rail is very fast, right? Generally, we surf the internet on the high-speed rail, and the network will be unstable. However, this will not happen to the Beidou mobile phone, because someone has done the test. It only takes 17 seconds to download a blockbuster with Beidou mobile phone. I don't need to say more about its network speed.
4, the signal is super strong. Beidou mobile phone can be said to be a signal artifact, because there is no signal in a remote desert or on the highest mountain-Mount Everest. Whether there is a signal depends on the height of the tower. There is no higher place on earth than a satellite! )
At the same time, Beidou Huawei mobile phone also has intelligent alarm, physical examination, smart home control and other functions.
The Beidou satellite (BNS) is the lifeblood of China and one of the four major satellite systems in the world. There are more than 130 Beidou satellites above the earth. In 2020, the Beidou global system will be built to provide services to users around the world.
Beidou satellite navigation system consists of three parts: space segment, ground segment and user segment. It can provide high-precision and high-reliability positioning, navigation and timing services for all kinds of users around the world, and has the ability of short message communication. It has initially possessed the ability of regional navigation, positioning and timing, with positioning accuracy of 1m, speed measurement accuracy of 0.2 m/s and timing accuracy of 10 ns.
Beidou has one of the four satellite licenses approved by the International Telecommunication Union, including GPS in the United States, GLONASS in Russia, Galileo in Europe and BNS in China. We should use our own satellite navigation system to protect national information security and avoid being controlled by others in future wars. We can't live in the world of American GPS all the time. China needs to strengthen its international voice.
I hope I can help you! Thank you for your adoption!
