How to distinguish the quality of mobile phone signal jammers
When people choose mobile phone signal jammers, they often cannot confirm the quality of the signal blockers by just looking at the appearance, and they are worried that they will buy jammers of poor quality. Here is how to distinguish the quality of jammers.
First, the most intuitive way to distinguish the quality of mobile phone signal jammers is to disassemble the device, from the device shell to the internal components, whether the design is reasonable and scientific, and whether the product's availability, durability and practicality are fully considered. While seeing the internal structure of the device, you can also see whether it is a conscientious merchant and whether the components on the PCB board are second-hand devices. If it is such a merchant, you can directly enter the procurement blacklist.
Second, it is the brand of mobile phone signal jammers. There are many brands of jammers emerging on the market, but there are not many brands of jammers that are truly powerful and reputable. Consulting more companies and accumulating more professional knowledge can also play a vital role in distinguishing the quality of jammers. For example, the way jammers of different frequency bands interfere with wireless signals, the interference range, and whether special frequency bands can be used, or jammers can be customized for different application sites, etc.
Third, whether the relevant functions of the mobile phone signal jammer's peripheral products can be met. Different jammer products may have some differences in the functions of the jammer products according to different application sites. There are many mobile phone signal jammers with imperfect functions on the market, mainly because some circuits for optimizing signals, such as automatic gain control, etc., are cancelled. Some jammers that cut corners have relatively large functional differences, which will lead to some jammers failing to meet the requirements at some sites with special requirements.
Fourth, if there is a certain amount of professional knowledge accumulation and detection instruments, such as spectrum analyzers. You can use a spectrum analyzer to check the output waveform of the interference signal of different frequency bands emitted by the jammer when using the cell phone signal blocker, as well as some parameters such as signal strength. Or directly test the interference range of the jammer, and purchase it if it meets the requirements to avoid pitfalls.
