5G signal jammer



The application of 5G communication technology has been widely deployed and popularized in various cities in the past three or four years, and mobile phone end users have almost completed the process of upgrading from 4G to 5G mobile phones. This is like a spear and a shield. , In places where the use of mobile phones needs to be restricted, the upgrading of 5G signal jammers is also being carried out simultaneously. However, according to the information fed back to us by many dealers and customers, during the installation and commissioning of the mobile phone signal interference project, the thorny problems encountered are obviously much more than in the previous 3G or 4G era, especially in the bustling major cities in the city. This is especially the case in urban areas. Here we will summarize the pain points and difficulties of installing and using 5G signal jammers in cities, and propose corresponding analysis and solutions.

According to the construction and deployment information of 5G base stations disclosed by major operators, we can clearly know that in the main urban area of the city, the construction density of 5G base stations is much higher than that of previous 3G and 4G base stations. Moreover, from the perspective of 5G spectrum division applications, 2600MHz and 3600MHz in the high-frequency band are mainly used. Compared with the 1.8GHz frequency band and 2.1GHz frequency band used by 3G and 4G a few years ago, this is a higher frequency. One step further. The higher the frequency, the worse the diffraction ability of radio frequency information, the worse the anti-interference ability, and the shorter the transmission distance. In order to ensure stable transmission of 5G signals and reliable data transmission rate, various communication operators can only build 5G base stations more densely. This has brought huge trouble to whether the 5G signal jammer can exert the ideal jamming effect. The closer the 5G base station is to the 5G signal jammer, the worse the interference effect of the jamming device will be. If the construction density of 5G base stations is less than 500 meters apart, or even reaches a distance of two to three hundred meters, the use of conventional low-power 5G interference devices will indeed hardly cause much interference.

Due to the excessive construction density of 5G base stations, the impact on the 5G signal jammer cannot ensure sufficient interference range. The solution is usually tried in the following ways: for the 5G frequency band on site, separately increase the high-power module of the corresponding frequency band; Or replace the original omnidirectional antenna with a lower gain value with a directional antenna with a higher gain value.
