Last year, the long-awaited Huawei Mate series returned to the consumer’s field of vision, along with the news of the Beidou satellite that Huawei has been researching and developing for many years.
Not long after the release of the Huawei Mate 50 series, the Apple iPhone 14 series also announced that it is equipped with satellite communication technology. The satellite communication technology field of smartphones has officially become a battleground for high-end models.
Recently, a news report made the Beidou satellite information technology carried by Huawei Mate 50 series attract widespread attention again: a donkey friend found wild animal footprints while hiking in the snow field, so he left the team to look for animals to take pictures.
However, due to the heavy snow and the complex environment, the visibility was too low. The traveler was lost and could not return to the agreed meeting place on time. At the same time, the mobile phone signal was missing in the extreme environment in the wild, so he could not get effective contact with the outside world. Therefore, the donkey friend used the Huawei Mate 50 mobile phone in his hand to send a distress signal to his teammates and was rescued.
In recent years, the environment has changed and adventure activities have become popular, and such outdoor lost contact incidents have emerged one after another. For their families, the torment of waiting is even more hopeless and helpless. The purpose of carrying the Beidou satellite message function on the mobile phone is to minimize the occurrence of such extreme “lost connection” situations.
Since Huawei mobile phones began to carry Beidou satellite news, this technology has been praised by countless netizens. This time, the successful escape of donkey friends is not the first time that Huawei mobile phones have played a role in practical applications.
Previously, a Huawei Mate 50 series user did not notify his family when he was fishing at sea. Since there was no mobile phone signal at sea, the user used the Beidou satellite communication function to send a message to his family, but his family mistook it for a distress signal and called the police.
Although there was no danger in this “Oolong incident”, for the functions related to life, it is better to go all out than to save one time by mistake.
At present, only some models of Huawei and the Apple iPhone 14 series are equipped with satellite communication technology on the market, but there are essential differences in the implementation of functions between the two.
First of all, the Beidou satellite communication technology used by Huawei is based on the Chinese Beidou satellite navigation system, as the name suggests, and the principle of communication is through the regional short message service supported by the third-generation Beidou navigation system.
In terms of satellite selection, Huawei’s satellite communication technology chose three Beidou GEO satellites, that is, geostationary orbit satellites. A satellite in geostationary orbit revolves on the equatorial plane of the earth, and the time for one revolution is exactly 24 hours, so it is a relatively stationary satellite for the ground.
At the same time, the three Beidou satellites will always be aimed at a certain area on the earth, and the equipment on the ground can fix the launch direction without frequent adjustments. These three satellites are located in the directions of 80°, 110.5° and 140° east longitude, which is the southern sky we are facing.
Under this premise, Huawei designed a brand-new star-finding guide UX, which uses a visual interface to reduce user learning costs. It can enable mobile terminals to automatically find the location of satellites, establish a more stable connection and better improve the performance of sending and receiving information. .
The advantage of this is that in the process of using satellite communication, the system only needs to guide the user to align the Huawei Mate 50 with the satellite, and the satellite communication can be realized at a fixed angle, instead of following the satellite’s moving trajectory to make corresponding angles. Adjustment.
The satellite communication technology used on the Apple iPhone 14 series is in cooperation with Globalstar. The low-orbit communication satellite of Globalstar is responsible for the Apple satellite communication function, and the low-orbit satellite faces many problems in the experience.
The biggest problem with low-orbit satellites is that they orbit the earth for a short period of time, which leads users to use iPhones to communicate with satellites. In addition to searching for satellites, users also need to follow the trajectory of satellites, so that the antenna on the mobile phone is always aligned with the satellites. When users use this function, they need to perform cumbersome operations.
Most importantly, Huawei’s Mate 50 series is the industry’s first mass-market smartphone that supports Beidou satellite news, which can be used by domestic users, while the iPhone 14 series is currently only available in the United States and Canada.
When the user is in an extreme environment, the Beidou satellite messaging technology supported by the Huawei Mate 50 series can help the user establish a life channel with the outside world, send text and positioning to the outside through the Changlian App, and support multiple locations to generate trajectory maps.
For most users, Beidou satellite communication technology is a function that they will never use in their lifetime, but once it is used, it is a real life-saving function.
Life is always above everything else. Therefore, in the research and development of satellite communication technology, Huawei has spared no effort. It took more than three years to go over mountains and mountains, and 20 years of star deployment to bring this life-related function to smartphones.
In addition, in order to cooperate with this technology, the Huawei Mate 50 series has also undergone all-round upgrades in terms of reliability. It not only pioneered the reshaping of the glass structure, but also brought stronger and harder Kunlun glass.
The drop resistance of the Huawei Mate 50 series has been increased by 10 times, and it is also the industry’s first mobile phone that supports constant temperature charging of the entire body, which can also be used normally in extremely cold environments. At the same time, IP68 dustproof and waterproof and emergency mode can bring users a full sense of security, and reduce battery life anxiety when traveling outdoors.
As the brand-new Huawei Mate 50 series, once launched, it once again set off a frenzy of buying by consumers, which has something to do with the product innovation concept that Huawei has been adhering to for many years.
For a long time, Huawei has always attached great importance to user experience, and regards the important task of promoting the development of the industry as its own responsibility, constantly breaking through itself to achieve technological innovation, bringing consumers the ultimate black technology, and all-round high-quality and secure experience.
The Huawei Mate 50 series is such a masterpiece of technological innovation, and it will continue to lead the industry in innovation and set a high-end flagship benchmark.
