When you buy a mobile phone signal jammer, you can't confirm the quality of the jammer just by looking at its appearance, and you are worried about buying a jammer with poor quality. Here is how to distinguish the quality of the jammer.

First, the most intuitive way to distinguish whether the mobile phone signal jammer is good or bad is to disassemble the device. Whether the design is reasonable and scientific from the device shell to the internal components, and whether the usability, durability and practicality of the product are fully considered. When looking at the internal structure of the equipment, we can also see whether it is a conscientious business, and whether the components on the PCB are second-hand components. If it is such a business, it can directly enter the purchase blacklist.

Second, it is the brand of mobile phone signal jammer. Now there are many jammer brands emerging in the market, but there are not many jammer brands with real strength and reputation. Consult more companies and accumulate more professional knowledge, which can also play a vital role in identifying the quality of jammers. For example, jammers in different frequency bands can interfere with wireless signals in ways and ranges, and whether special frequency bands can be used, or customized jammers can be used in different application sites.

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 the different application sites. There are many cell phone signal jamming devices with imperfect functions on the market, mainly eliminating some signal optimization circuits, such as automatic gain control. Some of the jamming devices that cut corners on work have quite different functions, which will lead to some jammers failing to meet the requirements in some use sites with special requirements.

Fourth, if there is a certain accumulation of professional knowledge, and there are detection instruments, such as spectrum analyzer. The spectrometer can be used to check the output waveforms of interference signals of different frequency bands transmitted by the jammer, as well as some parameters such as signal strength, when the mobile phone signal jammer is used. Or the interference range of the jammer can be directly tested, and those meeting the requirements can be purchased to avoid stepping on the pit.
