We all know the importance of modern communication. Mobile phones now play an irreplaceable role in our lives. The first thing people do when they wake up every day is to pick up the mobile phone and double it. When we use a mobile phone, we will find a The biggest problem is that sometimes when using a mobile phone to go to some remote areas or mountains, there will be no signal, so satellite communications have always been desired. Advanced satellite communication networking has the advantages of flexibility, wide coverage, and freedom from geographical environment. It can be said that it is very useful. We may need satellite communication support in field exploration, border patrol, and earthquake relief. Now CONQUEST conquers and releases the S18 Tiantong satellite mobile phone. With such a mobile phone, our calls will not be affected by the signal and will not be restricted by the signal. But is the S18 Tiantong satellite mobile phone really so good, and is there any disadvantage? I consulted the CONQUEST staff, but they didn't know. Later, I saw that the original satellite mobile phone on Tiantong No. 1 was not perfect. Satellite phones can make calls as long as they can see the sky, and they are domestically autonomous systems with high security and will not be overheard by foreigners. However, because the satellite is relatively far from the ground, the signal is weak, so the Internet is slow, and you cannot talk indoors. The most important thing is that satellite phones are more expensive. After reading the detailed introduction of satellite mobile phones on Tiantong No. 1 online, I felt that I had a better understanding of satellite mobile phones, and the demand for satellite mobile phones became clearer. Although there are some shortcomings, when we need emergency, it is worthwhile for Tiantong satellite mobile phone to be expensive, because it can save lives.
