With the continuous popularity of smart phones and mobile Internet, people use mobile phones and networks more and more frequently. China's mobile phones communicate through signal base stations on the ground. Affected by geographic environment and construction costs, some remote areas have unevenly distributed base stations, which results in no signal or poor signal in some areas.
The development of technology has brought us satellite mobile phones. Now the phrase "not in the service area" will no longer be a problem for communication. It is a thing of history to want to contact each other, but it is no longer possible. Satellite mobile phones have no blind areas nationwide. It can realize barrier-free communication and bring security for outdoor travellers. It has become a good partner for people to travel. Satellite mobile phones rely on launching satellites for signal transmission and information communication. Satellite mobile phones are different from ordinary mobile phones. Satellite mobile phones do not need to be connected to a telecommunications network through a base station set up on the ground, but directly communicate data with satellites. Transmission. The satellite mobile phone has good communication signals, wide coverage, small and light, and is extremely suitable for carrying out; in addition, the satellite mobile phone has fewer transmission links, high reliability, and is not affected by geographical conditions and weather, and can obtain high-quality communication signals; satellite communications The cost of the system does not increase with the increase of the communication distance, and the satellite mobile phone is no longer limited to the communication signal of the use area, and the applicability is extremely strong. Satellite mobile phones are very common in outdoor hiking, vehicle positioning, marine positioning, unmanned area exploration and other fields. Ordinary mobile phones are often unable to be used in remote areas and at sea because of no signal. Satellite mobile phones allow communication without blind spots. It comes in handy; small and light, easy to carry, satellite mobile phone allows you to communicate anywhere, anytime, anytime, anywhere. CONQUEST S18 Tiantong version has an independently developed satellite communication module, equipped with Tiantong satellite communication technology, to achieve signal coverage and barrier-free communication in China, whether you are in the vast ocean, mountains, grasslands, forests, Gobi, desert, as long as The mobile phone can see the sky and can make calls and send text messages one day and one day. For those who love outdoor adventures, there is no need to worry about the loss of contact, and their own safety is also more guaranteed.
