Portable Jammers

Advantages of built-in portable jammer compared with external signal jammer:

In terms of energy saving and heat dissipation, the built-in mobile phone portable jammer cannot be compared with the external mobile phone signal jammer. From the external structure, the built-in portable jammer integrates the transmitting antenna, the power supply and the heat sink in an external plastic shell, which is more beautiful and convenient from the appearance. Power supply and other advantages, in some school examination rooms, conference rooms, confidential places, the flow of people is easy to manage or frequently moving areas have great advantages.

Then the external mobile phone signal jammer is made of thick pure aluminum alloy through oxidation paint and other processes to combine the circuit board with the shell and make full use of the shell to achieve good heat dissipation effect. Because the antenna adopts the SMA head outside The external power supply is not conducive to long-term mobile use, the operation is cumbersome, and the installation is inconvenient, but its own advantages are also particularly strong. The external heat dissipation effect is better due to the built-in mobile phone signal jammer, and the better matching of the external transmitting antenna and the signal jammer The use effect will be better, because the external mobile phone signal jammer power supply and the host are also separated, it will not add an additional burden to the host and can work better and stable for a long time. Combining the above advantages, the external mobile phone signal jammer is actually more suitable for school classrooms, student dormitories, churches, troops, prisons, detention centers and other fixed places that require continuous work and stable use for 365 days.

Factors that should be considered in the selection of mobile phone signal jammer equipment:

The choice of portable jammer for mobile phones is good for you. Whether the portable shielding device is qualified can be seen from the company's various certifications, materials used, and debugging processing technology. There are some basic requirements for the selection of a mobile phone signal jammer. If there is a formal company registration, whether there is a registered trademark, etc., you can ask the manufacturer to provide a mobile phone signal jammer debugging photo, internal structure photos, etc. are all to judge a mobile phone signal jammer Basic standards. From the debugging photos, it can be seen whether the frequency of a portable jammer is square and there is clutter, whether the frequency debugging width and power are qualified, is it true that there are 5 outputs in the 8 outputs outside, and we have dismantled many of them and found many unscrupulous merchants in the market. Low prices attract customers to adopt this method. Through the above methods, at least it can be judged that it is not produced in small factories and small workshops, and the quality is relatively guaranteed.

Working principle of portable signal jammer:

The portable scrambler scans from the low-end frequency of the forward channel to the high-end frequency at a certain speed during operation. This scanning speed will cause garbled interference in the SMS signal received by the mobile communication (mobile phone), and the mobile communication (mobile phone) cannot detect the normal data sent by the base station, resulting in the mobile communication (mobile phone) unable to establish a connection with the base station. Mobile communication manifests itself as searching the network, no signal, no service system, etc. The portable frequency jammer is multifunctional and can completely shield 2/3/4G signals, including current 5G signals, as well as GPS, WiFi, and GSM signals.
