Nowadays, many users have installed and turned on cell phone signal blockers, and some of them will not be able to block mobile phones. After studying the main reasons, the distance from the base station in the area is a very noteworthy influencing factor. However, regarding mobile phone base stations, it is actually necessary to make a distinction. There are many types of communication base stations. What can affect the effect of mobile phone signal jammers? There are micro base stations and pico base stations.
Base stations are relatively easy to identify and are generally installed on large tower poles or large street lamp poles. The transmission power of macro base stations is also relatively large, and their coverage area can generally reach a level of more than 1,000 meters. If there is such a macro base station within a distance of two or three hundred meters near the application site of the mobile phone signal jammer, the impact on the shielding effect will be very large. Under abnormal circumstances, there is not even a little shielding effect.
The number of small base stations is larger than that of macro base stations. They are usually installed in urban areas with a relatively concentrated population, with macro base stations as the core. Their transmission power is lower than that of macro base stations, and the impact on the shielding effect is also very obvious. It is generally required that there should be no micro base stations within at least two or three hundred meters around the application site of the mobile phone signal jammer.
The transmission power of the pico base station is even smaller than that of the micro base station, and it is generally used for indoor installation. It is usually installed in the corridors of buildings or in shopping malls, cultural centers, etc. The appearance of the pico base station is very delicate and easy to be concealed. Even its appearance will be hidden, such as being made into the appearance of speakers, speakers, billboards, etc., so that people will not easily discover the real main purpose. Because the power of the pico base station is relatively small, the impact on the mobile phone signal blocker is relatively limited. Therefore, when encountering the application site of the pico base station nearby, sometimes it can be taken to immediately dismantle or turn off the pico base station in close range to ensure a better shielding effect.
