Pain points and difficulties in installing and using mobile phone signal jammers in cities

In the past three or four years, 5G communication technology has gradually become popular in various cities, and mobile phone users have basically completed the transition from 4G to 5G. However, this also brings challenges to places where mobile phone use needs to be restricted, and mobile phone jammers need to be upgraded. According to feedback from dealers and customers, the installation and debugging process of mobile phone signal shielding projects is more difficult than the previous 3G or 4G era, especially in prosperous urban areas. This article will analyze and solve the pain points and challenges of installing and using Cell Phone Jammers in cities.

Through the 5G base station construction and deployment information provided by major operators, it can be seen that the density of 5G base stations in the main urban area is much higher than the previous 3G and 4G base stations. In addition, in terms of 5G spectrum allocation, it is mainly concentrated in high-frequency bands such as 2600MHz and 3600MHz. Compared with the 1.8GHz and 2.1GHz bands used by 3G and 4G in previous years, 5G is developing towards higher frequencies. Higher frequencies lead to a decrease in the diffraction ability of radio frequency signals, a weakened anti-interference ability, and a shortened transmission distance. In order to ensure stable 5G signal transmission and reliable rate, communication operators have to build 5G base stations at a higher density. However, this poses a huge challenge to the shielding effect of mobile phone signal jammers. When the distance between the 5G base station and the signal jammer is too close, the shielding effect of the device will be affected. If the interval between 5G base stations is less than 500 meters, or even only two or three hundred meters, the traditional low-power 5G shielding equipment will not be able to provide sufficient shielding.

The density of 5G base stations is too high, which has a great impact on the effective range of mobile phone signal jammers. For such situations, several solutions are usually tried, including adding a high-power module suitable for the on-site 5G frequency band, or replacing the original omnidirectional antenna with a directional antenna with a lower gain value and higher gain.
