When you buy a wifi jammer, you often cannot confirm the quality of the jammer by just looking at the appearance, and you are worried that you will buy a jammer of poor quality. Here's how to identify the quality of the jammer good or bad.
Steps to identify a wifi signal jammer
First, the most intuitive way to distinguish the quality of the wifi jammer device is to disassemble the device, from the device shell to the internal components, whether the design is reasonable and scientific, and whether the usability, durability, and practicality of the product are fully considered. While seeing the internal structure of the device, you can also see whether it is a conscientious businessman and whether the components on the PCB board are second-hand devices. If it is such a business, you can directly enter the purchasing blacklist.
The second is the brand of wifi signal blocker. Now there are many brands of jammers on the market, but there are not many jammer brands with real strength and reputation. Consult a few more companies and accumulate some professional knowledge, which can also play a crucial role in identifying the quality of jammers. For example, wireless wifi jammers in different frequency bands interfere with wireless signals, the interference range, and whether special frequency bands or customize jammers for different application sites, etc.
Third, whether the related functions of the peripheral products of the signal jammer can be satisfied. Different jammer products, depending on the application site, may have some differences in function of the jammer product. There are many imperfect wifi signal jamming devices on the market, mainly canceling some circuits that optimize the signal, such as automatic gain control and so on. Some of the jamming devices that cut corners have large differences in their functions, which will lead to some jammers that cannot meet the requirements in some use sites with special requirements.
Fourth, if there is a certain accumulation of professional knowledge, and there are testing instruments, such as spectrum analyzers. You can use a spectrum analyzer to check when the wifi blocker is in use, and you can intuitively see the output waveforms of the jamming signals in different frequency bands emitted by the jammer, as well as some parameters such as signal strength. Or directly test the interference range of the jammer, and purchase those that meet the requirements to avoid stepping on the pit.
