    Internal structure of mobile jammer

    Mobile jammer test report. The test items of the shield include appearance test, enclosure protection grade test, shielding signal function test, leakage current test, electrostatic discharge interference test, etc. The test report of the shield is complete    The installation position of the mobile jammer is also arbitrary according to the site environment. If there is a ceiling or a mo...

    Selection parameters of high  power signal jammer

    Power of high power signal jammer: power from equipment itself, antenna radiation (antenna gain, length, etc.), The shielding effect of indoor and outdoor highpower jammers is different: the generation, attenuation coefficient and reflective surface of cell phone signal and jammed data signal in the room are different Before interference, the compressive strength and quality of mobile phone signal...

    Mission of portable jammer

    The interference range of portable jammers varies according to the power of products. The interference radius of high-power portable jammers used in prisons can reach hundreds of meters, while the radius of low-power portable jammers suitable for examination rooms and meeting rooms is generally 1-10 meters, depending on the signal strength nearby and the distance of the base station.    ...

    Does the mobile phone have a signal when the radio jammer is running

    Over the years, radio jammer  have been used in various examinations in schools. When the radio jammer is started, what is the reason why the mobile phone signal is displayed?  1. There is a display signal on the mobile phone screen. When making a call, the mobile phone can still be used normally with good call quality and will not be affected. In this case, it is possible that the radio...

    Brief Introduction to the Defense Scheme of Handheld Jammer

    In order to achieve the comprehensive defense of UAVs, it is important to specify a comprehensive handheld jammer defense plan. In the early stage, we must fully communicate and understand the needs, conduct field surveys, recognize the problems of the site and the surrounding environment, and adopt a multifaceted scheme that combines a variety of equipment, such as handheld jammer anti gun, fixed...

    Change in number of Signal jammer

    With the development of signal jammer for decades, there are many kinds of jammers, which have different classifications in terms of power, types of jamming signals and jamming directions. Here, we focus on an important sub category of signal jammers: conventional low-power signal jammers. With the widespread application of mobile communication terminals, that is, mobile phones, low-power signal j...

    What brand of mobile phone signal will not be interfered by mobile jammer

    The principle of the mobile jammer is to transmit signals of the same frequency band as the signal base station through some shielding equipment, so that the communication equipment within a certain range can receive invalid signals transmitted by the jamming equipment and cannot receive effective signals transmitted by the signal base station, so that the signals of terminal communication equipme...

    Determinants of jamming effect of mobile jammer

    The mobile jammer is easy to install, and some small details before installation determine the interference effect of the mobile jammer in the future, the environment and height of the mobile jammer near the installation, and whether there is external interference damage. The interference signal is strong. Under normal circumstances, the installation of more than one meter and less than three mete...

    Tips for cell phone shield

    The cell phone shield the signal just like chatting with the base station. First, it sends a "hello" electromagnetic wave to the base station to show friendship. The base station responds after receiving the "hello", so the mobile phone receives the signal.  Shielding thecell phone shieldl is like a big speaker. When the mobile phone sends a friendly "greeting", it will send out an interferin...
