The most widely used mobile phone standard today is our gsm global mobile communication system. GSM standard equipment accounts for more than 80% of the current global cellular mobile communication equipment market. It is widely used, and perhaps we are most familiar with the use of mobile phones. Yes, calls and text messages rely on gsm to provide stable network data types. But the gsm network is far more than what we know. The gsm module is one of the directions that many electronics manufacturers are familiar with and carefully researched. It is used in many areas of life, but we do not understand. General access control security system, GSM network car security system and robots have been applied to gsm modules.
GSM also supports indoor coverage. The power of the outdoor antenna can be distributed to the indoor antenna distribution system through the power divider. This is a typical configuration scheme used to meet the high-density call requirements in the home, which is common in shopping malls and airports. Indoor coverage can also be achieved through wireless signals in buildings, but this can improve signal quality to reduce interference and echo.
Driverless cars will surely have a larger market in the future, but the premise is that there are many possible safety issues. We know that driverless cars need to use GPS, and GPS signals are susceptible to interference. Whether it is a magnetic field or equipment, gps blocker will make GPS unable to work properly. This is one of the problems that driverless car researchers need to solve. This problem cannot be solved, and driverless cars will not be able to drive safely on the road, because in life, GPS jammers are also very important anti-tracking devices for people. You may feel uneasy about where you need to go.
