If the area to be shielded is large and empty (such as warehouses squares auditoriums and conference venues, etc.), large outdoor jammers can be considered. If the area to be shielded is a small and medium-sized indoor environment with a simple structure (such as classroom examination room office meeting room lounge bathroom, etc.), and the actual area is not more than 100 square meters, then choose a small and medium-sized indoor shielding device Suitable. Relatively, its production cost and selling price are also lower. The former is smaller than the latter in terms of volume and actual output power of the interference signal. If the power of the jammer is less than the local The power of the base station signal will be signaled by the mobile phone.įirst of all, the types of signal jammers that should be selected for different shielding areas are not the same: in general, signal jammers are divided into indoor and outdoor types. If the power of the jammer is greater than the power of the local base station signal, then the mobile phone will have no signal. In layman's terms: When the mobile phone signal jammer is working, it will send out the frequency to interfere with the downlink signal of its base station. The mobile phone appears to search the network, no signal, No service system, etc. This scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station and achieve the purpose of shielding the mobile phone signal. The jammer scans from the low end frequency of the forward channel to the high end at a certain speed during operation. Within a certain frequency range, the mobile phone and the base station are specifically connected by radio waves, and data and sound transmission are completed with a certain baud rate and modulation method. It would be great if there was a jammer at this time! When you concentrate on reading, there is a loud phone ringing in the quiet library and your reading is interrupted, which is very frustrating. Schools use jammers to ban students from using mobile phones on campus to reduce disruption to normal classroom order and cyberbullying. Have you been interrupted by phone calls during the meeting? Does anyone send text messages or play with smartphones during the meeting? You need a cell phone jammer to prevent these things from happening. At this time, we should use some equipment to safeguard their legitimate rights and interests. Illegal activities of unscrupulous detainees who continue to use drugs for smuggling.Ĭinemas and theaters should have been places where quietly enjoy the art, but always some people will use the phone to break the quiet here. Prisons use cell phone signal jammer to block cell phone signals from local prisons to prevent This means that a jammer can block more and more frequencies.įrequency jammers can help people protect their privacy and avoid the threats caused by mobile phones, wifi signals, drones and other signal equipment. Of course, the design of jammers is increasingly inclined to comprehensive performance. Each of them is designed to work in a specific frequency range. It was invented to help people solve various problems from mobile phones, radio signals and wireless connections. Our cell phone jammer is suitable for all aspects of you.Ī signal jammer emits a device that emits a signal that is the same frequency as that used by a mobile phone to produce some form of interference to prevent signal transmission or reception. These devices have different sizes, colors and mechanical specifications, and most customers can adapt. Here we have 100% safe, stable and high-quality suppliers. High-performance cell phone blockers are needed whenever and wherever possible. We can guarantee that the quality of our products is in a leading position among the peers. They are all manufactured by our manufacturing technology team through the use of professionalism. Among the jamming devices are mobile phone jammers, GPS jammers, GSM jammers, wifi jammers and high-end drone jammers. Faced with the threat of information leakage from wireless networks, mobile devices, etc., our store provides you with professional signal jammers to block the signal frequencies required by mobile phones and other devices. The rapid development of mobile communication equipment and wireless networks today undoubtedly brings us convenience, but at the same time it also brings a lot of life problems, and even brings security risks.
