Will full-screen segment signal jammers interfere with other devices when in operation?
Full-screen segment signal jammers are commonly used in a variety of occasions, but it is important to understand the impact of these signal blocking devices on other electronic devices. Generally, we know that full-screen segment signal jammers can interfere with mobile phone signals and are often used to prevent cheating during exams. However, to fully grasp the function of these jammers and their impact, it is crucial to understand the principles behind signal blocking devices.
Full-screen segment signal jammers have different variations based on their appearance and antenna configuration. There are models with internal antennas, as well as models with external antennas. These jammers can be classified as low-power or high-power, depending on the intended area of use and coverage requirements. When used outdoors or in large areas with large floor spacing, it is recommended to use high-power full-screen cell phone jammers.
The working principle of the full-screen segment signal jammer is to operate at a frequency lower than the wireless channel and combine it with high-speed scanning. The scanning speed affects the ability of the mobile phone to receive SMS format signals. By preventing the mobile phone from detecting stable data transmitted by the base station, the jammer disrupts the connection between the mobile phone and the base station, effectively blocking the mobile phone signal, causing the mobile phone to display information such as searching for network, no signal, and no service.
It should be noted that when the full-band signal jammer is activated, it only affects the mobile phone and will not cause harm to other electronic devices. This is because the electromagnetic signal emitted by the jammer is limited to the operating frequency band specified by the regulatory agency for the mobile phone. The signal only interferes with mobile phone communications and is relatively static, with minimal impact on other electronic products.
Full-band signal jammers are not only used in examination rooms, but also in confidential meeting rooms, detention centers, and military sites. In particular, correctional institutions require full-band shielding to prevent prisoners from using their mobile phones to contact the outside world. In order to achieve the best coverage effect, it is recommended to use high-power full-band jammers in conjunction with low-power full-band signal jammers in areas with shielding blind spots.
