News on January 12th, the first satellite mobile communication system self-developed and built by China-Tiantong System officially provided services to the community from yesterday, which marked the beginning of the era of autonomous satellite mobile communication in China.
The commercial Tiantong satellite mobile communication system used this time was the "Tiantong-1" satellite launched in 2016. As an independent satellite communication system construction from satellite research and development to terminal production, the Tiantong system fills the lack of China's autonomous satellite communication field. In addition, the Tiantong satellite system also has the advantages of wide coverage and stable weather signals, which can provide users with various services such as data communication or location positioning.
As a type of microwave communication, the main purpose of creating a satellite communication system is to achieve "seamless" information coverage on the ground. Because the coverage and signal strength are much larger than those of a general mobile communication system, satellite communication will be one of the most important communication methods in the future information age. As early as March 2018, the Tiantong satellite communication system was tested in the country, providing data services based on the Tiantong satellite communication for various fields. Up to now, there are 25 different types including handheld terminals in the country. Tiantong satellite terminal equipment has obtained the network access license of the Ministry of Industry and Information Technology.
In January 2020, Shenzhen Kangkaisite Communication Equipment Co., Ltd. launched the Conquest S18 Tiantong satellite mobile phone to cooperate with China Telecom's Tiantong satellite business. It is a mobile phone that supports satellite calls and breaks through the performance of previous satellite mobile phone configurations. The short board is equipped with an eight-core 2.3GHz processor, and has internal and external IP68-class rugged defense capabilities. 6G operating memory and 128G storage memory also support a maximum 2TB expansion card, BOX sound cavity speakers, and so on. More importantly, the S18 is equipped with the Tiantong satellite communication technology with independent intellectual property rights in China, which has taken a big step towards the nationalization of satellite communication.
Once it has independent intellectual property rights, the communication fee can be greatly reduced. Originally, the high satellite communication cost of 10 yuan per minute was only 1.6 yuan per minute on the S18 Skycom satellite mobile phone. Many people can afford satellite phones.
Some people may think that satellite phones are not very useful, because the radius of your life is where there is signal coverage. But for donkey friends, outdoor adventure enthusiasts or sailors, they often move in places where there is no mobile phone signal, and there are not a few people who are in danger due to lost contact each year. Therefore, the CONQUEST brand launched the S18 Tiantong satellite phone The significance is extraordinary. If you carry an S18 satellite mobile phone at this time, you can make an emergency call for help at a critical moment, and you will be shocked.
Considering the convenience of daily use, the CONQUEST S18 supports three cards and three standbys, and one Tiantong card and two public network cards are usually the same as ordinary rugged mobile phones. And when traveling, you only need to bring the Skycom satellite card, and you can also contact the outside world when you are in a no-signal area. I believe that due to such excellent performance, the CONQUEST S18 Tiantong satellite mobile phone may become the standard mobile phone for many outdoor enthusiasts.
