During secret negotiations, it is particularly important to monitor the surrounding radio frequencies in all directions. The cell phone signal suppressor is designed to meet such challenges. It covers all frequency bands from 2G to 5G (including NSA and SA) and WiFi. Whether it is voice calls or data transmission, it can be blocked within the range of 5-40 (the best effect is 200 meters away from the base station).
In a complex wireless communication environment, it is particularly important to monitor the surrounding radio frequencies in all directions in highly confidential occasions such as secret negotiations. This box style multi-band 5G phone signal jamming device is designed to meet such challenges. It can quickly identify and respond to abnormal signals and effectively build a solid confidentiality barrier.
The device covers all frequency bands such as 2G, 3G, 4G, 5G (including NSA and SA) and WiFi. It interrupts the communication link between the mobile phone and the base station by transmitting wireless signals that match the target frequency band. Both voice calls and data transmission can be shielded within the specified range.
The soft start circuit design avoids the sparking phenomenon caused by excessive instantaneous current shock when turning on or off, which damages the device or circuit.
The built-in temperature monitoring system dynamically adjusts the fan speed according to the real-time temperature to optimize the heat dissipation efficiency. The fan noise is extremely low and no obvious mechanical noise is generated during operation.
1. After startup, the radio interference signal of the specific frequency band of the target device is emitted.
2. The interference signal covers the target area, preventing the normal transmission of mobile phone signals.
3. The mobile phone cannot establish a connection with the base station, thus losing voice calls, text messages and data connection functions.
In addition, the device has a built-in high-efficiency filter module to filter out excess interference bands to ensure that signals outside the target frequency band (such as wireless microphones, etc.) are not affected.
The convenience of one-button start reduces the threshold for use. There is no need to adjust the frequency in advance. Just turn on the power and turn on the device to put it into use.
In order to achieve the best performance, it is recommended to use the device in an area 200 meters away from the mobile phone base station. When it is less than 200 meters, the closer to the base station, the shielding effect may be limited to a certain extent. At this time, the number of signal jammers can be increased to expand the interference coverage and improve the shielding effect.
