A mobile phone jammer is a device that blocks the communication between mobile phones and base stations by emitting radio waves of a specific frequency to interfere with mobile phone signals. It is usually used in places where mobile phone use needs to be restricted, such as examination rooms, conference rooms, theaters, and prisons.
Choose a suitable cell phone jammer
Frequency band coverage: Choose the appropriate frequency band coverage according to actual needs. Most mobile phone jammers are able to cover 2G, 3G, 4G, and even 5G bands, and some can block WiFi and Bluetooth signals.
Coverage: Choose an appropriate coverage range according to the size of the area to be shielded. Small jammers usually cover a range of several meters to tens of meters, while large jammers can cover hundreds of meters.
Brand and quality: Choose a reputable brand and manufacturer to ensure product quality and after-sales service.
Install a mobile phone jammer
Site selection: Choose a suitable installation location. Generally speaking, a mobile phone jammer should be installed in the center of the area where the signal needs to be shielded to ensure uniform signal coverage. Avoid installing the device in places with metal products or large electromagnetic interference.
Height: The installation height of the device should be as high as possible. It is usually recommended to install it at a height of 2 to 3 meters so that the signal can be better transmitted.
Fixed: Choose a suitable fixing method according to the type of device. Small devices can be placed directly on the desktop or wall, while large devices may require professional mounting brackets for fixing.
Power supply: Make sure there is a suitable power supply. Most mobile phone jammers need to be plugged in to work. Make sure the power interface is safe and reliable, and avoid long or damaged power lines.
Operation and use of mobile phone jammer
Start the device: After connecting the power supply, turn on the power switch. Usually the device will have an indicator light to show the working status of the device.
Debug the device: Some devices may need to adjust the frequency and power to ensure the best shielding effect. Make corresponding settings according to the instructions to ensure that the device works properly.
Monitoring effect: Use a mobile phone to test within the shielding range to ensure that the mobile phone cannot receive the signal. If the shielding effect is not ideal, the device position or frequency setting can be adjusted appropriately.
Regular maintenance: Regularly check the working status and power connection of the device to ensure long-term normal operation of the device. Clean the surface of the device to avoid dust accumulation affecting heat dissipation and signal transmission.
