We prohibit the use of mobile phones in various examination rooms, schools, gas stations, churches, courts, libraries, conference centers (rooms), theaters, prisons, etc. In some occasions, if you are not careful, the mobile phone will be turned on and brought in, so a technology is urgently needed to shield the mobile phone without affecting the use of other electronic products, so Cell Phones Block Public Calls came into being. For the installation of Cell Phone Jammer , everyone has always had such a question, that is, whether the mobile phone signal jammer has a good built-in shielding effect or an external one? First of all, there is no doubt that the external transmitter is better than the built-in one in terms of effect.

External Cell Phones Block Public Calls First of all, the antenna is separated from the RF components and will not affect each other. The antenna is configured according to the frequency, with high gain and good transmission effect. The disadvantage is that the installation is troublesome and the external antenna is easy to break. The built-in mobile phone signal jammer integrates the switch to convert the power supply, the power motherboard, and the antenna into one space. If it cannot be properly optimized, the frequencies will be intertwined with each other, and the power supply will interfere with the signal source, so the shielding effect will be poor. Therefore, the purchase priority is to choose the brand, the regular manufacturer, the qualified, and the three no products are rejected. We are your preferred manufacturer. The mobile phone signal jammer is a new type of information security product. It uses a specific electromagnetic signal to form an electric fence in the place that needs to be protected, so that the mobile phone cannot receive the data of the signal tower, and cannot establish contact with the signal tower, thereby eliminating the generation of mobile phones. negative impact, play a role in safety protection. The wireless mobile phone signal jammer only works for mobile communication, and it is harmless to the human body without shielding other electronic equipment.
