Some customers have asked us: In the process of performing the task of fleet safety protection, what is the interference effect of the vehicle-mounted frequency jammer in the driving state? Will the actual interference effect be affected by the speed of the vehicle?
The above-mentioned application scenarios are usually aimed at government leaders or important VIP customers. In the convoy where the vehicle is located, a vehicle-mounted frequency jammer is installed, starting from the departure of the convoy until reaching a safe destination. Here During the entire journey, regardless of whether you encounter parking, traffic jams, low-speed driving, high-speed driving, etc., always keep the vehicle-mounted frequency jammer working continuously to ensure that the entire fleet, especially the vehicles of important people, can be fully and reliably protected. Eliminate and prevent terrorists from detonating roadside bombs, car bombs, etc. by remote control.
When the vehicle-mounted frequency jammer is parked (stationary state) or driving at low speed, it is relatively easy to detect its interference effect on various signals, but if it is in the fleet and driving at high speed, its effective interference range will remain unchanged ?
According to our past experience in delivery acceptance and comprehensive testing, the interference effect of the vehicle-mounted frequency jammer at high speed (vehicle speed ≥ 100Km/h) is slightly lower than the test results at rest, and the decline is about 10%~20%, the overall impact is not large.
However, customers also need to be reminded that: for different signal types, the interference distance and effect of the vehicle-mounted frequency jammer will be affected by many factors. For example: For remote control or intercom signals, etc., the difference in the test results is not large when driving at low speed and high speed. For mobile phone signals of various standards, the difference is more obvious. This is mainly because the interference distance of the vehicle-mounted frequency jammer to the mobile phone signal is closely related to the distance from the mobile phone base station. When testing in a static state, the test results are relatively It is relatively stable. When driving at high speed, due to the continuous passing of the base station along the way, the mobile phone will also switch the base station signal intermittently due to the distance from the base station, resulting in the strength of the mobile phone signal always changing. Therefore, during the driving process of the vehicle-mounted frequency jammer, the interference distance to the mobile phone will always be in a dynamic state.
