A signal jammer emits a device that emits a signal that is the same frequency as that used by a mobile phone to produce some form of interference to prevent signal transmission or reception. It was invented to help people solve various problems from mobile phones, radio signals and wireless connections. Each of them is designed to work in a specific frequency range. Of course, the design of jammers is increasingly inclined to comprehensive performance. This means that a jammer can block more and more frequencies.

The working principle of signal jammer

5G telephone signal blocker

Within a certain frequency range, the mobile phone and the base station are specifically connected by radio waves, and data and sound transmission are completed with a certain baud rate and modulation method. The jammer scans from the low end frequency of the forward channel to the high end at a certain speed during operation. This scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station and achieve the purpose of shielding the mobile phone signal. The mobile phone appears to search the network, no signal, No service system, etc.

In layman's terms: When the mobile phone signal jammer is working, it will send out the frequency to interfere with the downlink signal of its base station. If the power of the jammer is greater than the power of the local base station signal, then the mobile phone will have no signal. If the power of the jammer is less than the local The power of the base station signal will be signaled by the mobile phone.

How to choose the most suitable jammer?

First of all, the types of signal jammers that should be selected for different shielding areas are not the same: in general, signal jammers are divided into indoor and outdoor types. The former is smaller than the latter in terms of volume and actual output power of the interference signal. Relatively, its production cost and selling price are also lower. If the area to be shielded is a small and medium-sized indoor environment with a simple structure (such as classroom; examination room; office; meeting room; lounge; bathroom, etc.), and the actual area is not more than 100 square meters, then choose a small and medium-sized indoor shielding device Suitable. If the area to be shielded is large and empty (such as warehouses; squares; auditoriums and conference venues, etc.), large outdoor jammers can be considered. If the area to be shielded is a large indoor space and the structure is more complex, the most ideal The shielding scheme is generally a combination of size: that is, a certain number of mainframes are deployed in a cellular manner to cover a large area, and a certain amount of minicomputers are used to eliminate blind spots, so as to achieve the most ideal shielding effect within a reasonable budget.
