In order to purchase a Gsm scrambler, in addition to the gsm network, you also need to shield the signal type, such as whether you need to shield the 3G and 4G network frequency bands. In this way, you can buy a cell phone blocker that can block all cell phone signals. In addition, since you have already purchased an electronic jamming device, you need to consider where to use it. Portable jammers are convenient for indoor and outdoor use, while desktop jammers use multiple antenna designs. As the name suggests, it will be widely used not only in individuals, but also in prisons, courts and other large venues. It has a wider interference range and more types of signal shielding. I personally recommend using an 8-antenna portable gsm encryptor. It is sufficient to meet your needs and provide a quiet reading environment when quiet is needed. For enterprises and important organizations, a powerful multi-antenna desktop jammer will be your better choice. In terms of functionality and interference radius, this is very obvious and is considered sufficient for large-scale applications.
The ISM 2.4G and ISM 5.8G frequency bands commonly used by humans and machines have the functions of forcibly shielding drones, interrupting graphics, signal positions, and approaching/returning/stopping. .. Teshinshin has developed a self-developed Drone jammer, which is powerful and can reach a distance of 1-5 km (depending on the use environment). Our company can shield the positioning signals of GPS satellites, as well as the 2.4G and 5.8G frequencies commonly used by drones, and can control the position of the drone’s remote control. Signal interruption forces forced/return/unstoppable. Have you heard of cell phone jammers? If you don’t ask, you may use your phone frequently. Of course, jammers are products that block the radio signals of electronic products (such as mobile phones, GPS and WIFI).
More specifically, a mobile phone jammer that suppresses communication with a mobile phone transmits interfering radio waves in the same frequency band as the frequency band used by the mobile phone and PHS, making the radio waves received by the mobile phone worse. This is to prevent the use of mobile phones in surrounding areas. Introduce in detail that WiFi jammers disable eavesdropping and SIM eavesdropping using mobile terminals (including smart phones and i-phones). Even if eavesdropping devices using mobile phone terminals (including smart phones/i-phones)/SIM card eavesdropping devices are installed inside or inside the vehicle, communication (out of service area/interference) will be blocked to prevent eavesdropping. By sending high-power RF signals in the same range as the mobile phone communication signal that needs to be blocked, interference may occur in mobile phone communication (in a certain area). This wifi jammer allows you to choose a cut-off frequency range and selectively block only these frequencies. It can be used to prevent GSM, CDMA, 3G/4G and other popular mobile standards from working properly.
