Is there any way to prevent mobile phone signal jammers from blocking the signal?
Currently, cell phone signal jammers are used in many places everywhere, and there are also some places that will affect the use of mobile phones by people living nearby, so this problem is also a very serious matter. So is there any way to prevent mobile phone signal jammers from blocking the signal?
There are two things to pay attention to in this question. First, how many times do you use your mobile phone? 2 is whether there is a problem with the mobile phone itself. In daily life, the mobile phones we use are common devices on the market. Their power is generally specified, fully complies with national regulations, and has no impact on the body. The networks accepted by mobile phones are usually those of the three major operators (China Mobile, China Telecom, and China Unicom), so all current mobile phones can support the frequency bands used by the operators. Therefore, mobile phones generally cannot prevent mobile phone signal jammers from blocking signals. In fact, the jammer performs corresponding interference according to the frequency bands of the operator's base station, so that the mobile phone cannot operate in these frequency bands, and plays the role of blocking the connection with the base station.
There are two ways to block the work of the jammer:
1. Choose to use a frequency band that is not within the range of the signal jammer
2. Install base station signal amplifier beyond the use of ultra-high power communication
However, these two methods are extremely difficult to implement and are not supported by the three major operators, nor are they supported by self-made mobile phones. They both require the cooperation of base stations, so they are very difficult and almost impossible to implement.
