Vehicle-mounted signal jammer equipment is an interference device installed on a vehicle. It is mainly used to shield or interfere with the signals of wireless communication equipment, such as mobile phone signals and remote control signals. During use, its interference effect is directly related to whether the task can be successfully completed, so it places very strict requirements on the vehicle-mounted signal jammer equipment itself. The factors that affect the interference effect of the vehicle-mounted signal jammer include the following aspects. signal jammer
1. Signal strength at the use site: The signal interference range of the vehicle-mounted signal jammer equipment is affected by the signal strength at the site. The on-site signal strength is mainly determined by the distance of the base station and is closely related to the strength of the mobile phone signal. However, different mobile phone operators also have different strategies for signal distribution, making signal quality difficult to predict. Therefore, when setting up a vehicle-mounted signal jammer device, the spectrum distribution and signal strength can be measured to select specific modules to maximize the interference range, or contact the operator to reduce the signal strength on site. For other remote control signals, the interference effect depends on the distance between the signal source and the suspected explosive, which is difficult to predict. Therefore, the focus should be on shielding the remote control signal so that the interference remote control signal module of the vehicle-mounted signal jammer device can interfere seamlessly.
2. The transmit power of the radio frequency module: The interference effect of the vehicle-mounted signal jammer device is also related to the transmit power of the radio frequency module. The greater the transmission power, the greater the interference range. However, if the bandwidth of the signal transmitted by a single module is too wide, the interference effect will also be affected. In order to achieve the best interference effect, high-power radio frequency modules should first be selected, and secondly, the frequency bandwidth of the signal transmitted by a single module should be reasonably allocated to maximize the interference range.
3. Adaptability of vehicle-mounted signal jammer equipment: The types and frequencies of wireless signals interfered by vehicle-mounted signal jammer equipment vary, so the adaptability of vehicle-mounted signal jammer equipment is particularly important. Vehicle-mounted signal jammer equipment should have interference adaptation capabilities for various wireless signal types and frequencies, so that it can exert the maximum interference effect in various environments and ensure the safety and stability of the equipment.
4. Interference from the vehicle itself: The vehicle-mounted signal jammer device itself will also produce a certain amount of electromagnetic wave interference, which may have an impact on other electronic equipment. Therefore, additional shielding or isolation measures are sometimes necessary to reduce the effects of internal interference in vehicle-mounted signal jammer devices.
