Desktop mobile phone jammers are relatively stable

Before buying, you need to know which signals you want to block. Ordinary mobile phone signals (2345G) can be selectively blocked. If you only block 2G or only 345G, this can be adjusted before leaving the factory. In addition, there is 2.4GWIFI, 5.8GWIFI, VHF, UHF and other frequency bands. Here we need to explain the function of each signal frequency band. Simply put, 2G is the frequency band for making phone calls, and 2345G is the frequency band for mobile phones to surf the Internet, so it depends on the specific requirements for shielding the frequency band. The appearance of the mobile cell phone jammer The mobile phone signal jammer can be divided into an external antenna and an internal antenna. In general, the external antenna extends outward because the antenna is external, so it occupies a larger space than the built-in antenna. Larger; because of the antenna that extends outward, the effect of the external antenna is more stable.

The end of semester, high school entrance examination, college entrance examination time, and security have become hot topics again. Among them, security inspection doors, hand-held mobile phone jammers and other equipment for detecting security inspections need to be further updated and upgraded. As a security inspection door manufacturer, I hope to provide more reasonable security inspection programs and configuration technologies. The school uses security inspection gates, mainly to conduct security inspections on candidates, check violations and tools, if there are suspicious situations, use handheld mobile phone jammers to perform a second scan inspection, and then to maximize the inspection of electronic equipment that affects the safety and fairness of the test , So many candidates. Sensitivity requirements: Due to the relatively low metal content of some electronic equipment, the metal sensitivity inspection requirements of school security gates are not low, and they must reach the inspection level of at least one 1 cent coin size metal object. This is the best check.
