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 jammers 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 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 shield wireless signals, the shielding range, whether special frequency bands can be used, or the jammers can be customized for different application sites, etc.
Third, whether the relevant functions of the peripheral products of the mobile phone signal jammer 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 shoddy shielding equipment has relatively large functional differences, which will lead to some special requirements in some use sites where some jammers cannot meet the 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 it, as well as some parameters such as signal strength. Or directly test the shielding range of the jammer, and purchase it if it meets the requirements to avoid pitfalls.
