The police in many cities are basically equipped with a signal jamming vehicle. The main core component in the signal jamming vehicle is the jamming host, which is composed of multiple RF modules. The signal jamming vehicle can also selectively turn on some RF modules according to different tasks.

Then, it is a professional question to choose which RF modules to turn on according to the different tasks to be performed. Let's answer this question for you.
In case of mass incidents, the signal jamming vehicle shall be dispatched to control the trend of public opinion and communication control. At this time, the signal jamming vehicle shall turn on the mobile communication module and WiFi module. And it is best to park the signal jamming vehicle at a relatively high position, and raise the antenna before supplying power to the RF module.

When it is necessary to perform the task of anti-terrorism and anti explosion, dispatch the signal jamming vehicle to jam all suspicious signals of all suspected remote-controlled bomb frequencies. In order to prevent incomplete coverage of wireless signals, it is necessary to turn on all 20-6000mhz RF modules of the signal jamming vehicle and seamlessly suppress all common wireless modules to ensure that the bomb removal task is safe
