With the official announcement of the support for satellite communication of the two latest flagships, the Honor Magic6 and OPPO Find X7, it has also officially ended the monopoly of Huawei mobile phones in this technology. Although many people ridiculed that no manufacturer could figure it out before Huawei did not come up with satellite communications, as soon as Huawei got it, friends and businessmen also quickly figured it out. But it's certainly a good thing at the consumer level
After all, this is a life-saving function at a critical moment, turning ordinary mobile phones into satellite phones, and the range of use is much wider. However, there is still a problem at the moment, that is, whether it is Huawei or Honor OPPO mobile phones, although they all support satellite communication functions
However, they can only rely on the Tiantong-1 satellite of China Telecom, so only telecom cards can be opened. However, as we all know, the number of domestic telecom card users is not the most, not to mention that Unicom also occupies a large share, and the largest number of users is mobile cards. So even if you buy a mobile phone that supports satellite communication, you still can't use it without a telecom card. This is also a problem that plagues many people
But just today, there is good news that mobile has officially joined the battlefield. Recently, China Mobile Research Institute and the industry jointly developed a spaceborne base station based on the 3GPP R17 NR NTN standard, and completed the ground communication test and space environment adaptability test.
The so-called spaceborne base station not only supports the current satellite text messages and satellite telephones, but also supports the satellite Internet function for the first time! At present, the spaceborne base station has completed the mechanics, high and low temperature, thermal vacuum, aging and other tests and anti-radiation performance evaluation, and meets the operating conditions in orbit. In terms of network speed, the user download rate can reach 15Mbps when the 20MHz bandwidth is measured in the satellite mode
The upload rate can reach 822kbps, and the maximum loopback delay is 9.2ms, the performance is basically in line with expectations, and it can be optimized in the future, and finally realize satellite Internet access services for public mobile phones. Judging from the speed of this upload and download, there is no problem with general video calls and web browsing
However, it is unclear how long it will take for China Mobile to launch the service, and the cost is unknown. But this is good news, because having access to the Internet is much more useful in times of crisis than texting and phone calls. With the addition of mobile, China Unicom is expected to follow up in time. If nothing else, Xiaozhi boldly predicts that next year's mid-to-high-end mobile phones will be equipped with satellite communication functions as standard, and in 2025, there is also hope that the thousand-yuan machine will be used, and finally achieve universal popularity!
