Jammers became the second largest electronic device after mobile phones

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, perhaps we are most familiar with the use of mobile phones. That’s right, phone and SMS rely on gsm to provide stable network data types. But the gsm network is far more than we know. The gsm module is one of the directions that many electronic manufacturers are familiar with and carefully studied. It is used in many areas of life, but we do not understand it. General access control security system and GSM network car security system and robot have been applied to gsm module.

The technology world has entered the era of 4G mobile, and more and more operators are closing GSM and CDMA second-generation (2G) networks. According to a report by IDG News Agency, many GSM network operators around the world have gradually shut down and no longer provide services. GSM network functions affect people’s lives. Earlier, Telstra announced that it would shut down its GSM network by the end of 2016, while AT & T, the largest mobile operator in the United States, had announced that it would shut down its GSM network by January 1, 2017. Singapore’s three major mobile operators M1, Singtel and StarHub are the latest companies to announce a timetable for closing GSM. The two companies stated that they will shut down the GSM network on April 1, 2017. Three operators in Singapore said that the number of users currently using the GSM network is very small. For most mobile phone users, it does not matter whether the operator shuts down the 2G network.

GSM network functions affect people’s lives. This is not only the basis of mobile phone voice communication and short message service network, but online news recently said that the latest technology of cruise navigation and drone tracking in Russia using GSM network also has very important applications. Russia’s latest “defense” airspace monitoring system can use GSM networks to identify and track drones, cruise missiles and low-altitude aircraft, but can track airspace below 500 meters (less than 500Mm / s), and the latest monitoring system can be used to upgrade Civil aircraft to assist the rescue operation after the crash.

In addition to the innovation of new mobile phone baseband chip technology and the strong support of carrier network systems, today’s smartphones can also achieve smooth Internet access, watch videos, remote voice and other functions. 2G network calls, 3G network access to the Internet, and 4G networks can see video. With the continuous improvement of network formats, mobile phone functions have also undergone tremendous changes. Now, with 4G networks all over the country, operators and telecom operators have begun to actively allocate 5G, hoping to further expand the network format, but as the network continues to be updated, its portable jammer have also appeared to restrain it. , For example: mobile phone jammer, gps jammer, drone jammer, WiFi jammer, etc.
