Types of Full Band Signal Jammers
Full band signal jammers can be classified based on their appearance into two categories: those with built-in antennas and those with external antennas. The full band signal jammer with an external antenna typically has a metal casing, while the one with a built-in antenna has a plastic casing. Additionally, based on the power output and coverage area, full band signal jammers can be further categorized into low-power and high-power variants. In outdoor settings where the distance between floors is significant, it is recommended to use high-power full band signal jammers for optimal performance.
Working Principle of Full Band Signal Jammers
The working process of full band signal jammers involves scanning frequencies from the lower end to the higher end of the forward channel at a certain speed. This scanning speed creates random interference in the received signal of mobile phones, preventing them from detecting normal data transmitted by base stations. As a result, the phones are unable to establish a connection with the base station, leading to phenomena such as network searching, no signal, or no service. In simpler terms, full band signal jammers emit frequencies that interfere with the normal frequencies received by mobile phones from base stations, rendering them unable to make or receive calls, send or receive messages, or access the internet.
It is important to note that when a full band signal jammer is activated, although the mobile phone may display a full signal strength, it will not have any actual signal during usage. Furthermore, the electronic devices other than mobile phones are not affected by the full band signal jammer. This is because the electromagnetic signals emitted by the jammer are confined within the frequency band specified by the country’s regulations and only disrupt mobile communication. Moreover, these signals remain relatively static and do not impact any other electronic devices.
Applications of Full Band Signal Jammers
Full band signal jammers find applications not only in examination halls but also in secure meeting rooms, prisons, and military facilities. Prisons, in particular, are required to be equipped with full band signal jammers to prevent inmates from having any contact with the outside world and to prohibit the use of mobile phones. In prison settings, it is recommended to use a combination of low-power and high-power full band signal jammers. Low-power jammers can be used in areas with signal blind spots, while high-power jammers are suitable for large coverage areas.
Conclusion
Full band signal jammers play a crucial role in maintaining security and integrity in various settings. By disrupting mobile phone signals, these devices prevent cheating during exams, unauthorized communication in high-security areas, and ensure compliance with regulations. Understanding the types, working principle, and applications of full band signal jammers is essential for effectively utilizing them in appropriate scenarios.
