Signal reconnaissance and location, take the initiative to lock the source, if things are said to be perfect now. Is that right? Even if it covers 2G, 3G and 4G, as well as Bluetooth and WiFi, it also shields bone conduction and invisible headphones. However, there are still newcomers who want to be able to crack the mobile cell phone signal jammer, and the method they use is a communication method with a custom frequency band. The walkie-talkie has become the only possibility. Custom frequency band means to jump out of mobile phone communication and Wi-Fi, Bluetooth and other frequency bands, and find a custom segment outside the frequency band covered by mobile jammers. In this case, it is bound to be developed for this purpose. Dedicated hardware equipment. Including signal generator and signal receiver.
According to the purpose of use, it is generally necessary to consider various factors such as signal attenuation and refraction. At present, some technologies on the market are mainly concentrated in the frequency band that can be received by the walkie-talkie. Some people with ulterior motives have also developed a transmission system that can break through the jammer of a flat phone based on the walkie-talkie frequency band. Whether it is cheating on exams or other illegal purposes such as eavesdropping, they are all targets of such communication systems. In this scenario, the mobile phone signal jammer cannot play a corresponding role. UAVs are used to detect and locate signal sources, but we are not helpless. The best way to deal with this scenario is actually signal detection and location, proactively attacking signal sources in specific frequency bands and arresting suspects. Therefore, during the normal college entrance examination, all the radio waves near the college entrance examination hall are actually recorded. Once there is an unrecorded signal, this radio wave will be quickly locked by the active detection system. Arrested by police officers. Multi-point positioning can determine the location of the signal source
