If the outdoor environment needs to be shielded, or the indoor area is large and relatively transparent, such as mining areas, oil depots, outdoor areas of supervision sites, large conference rooms, lecture halls, theaters, etc., high-power mobile phone jammers can be used. For high-power machines, due to the large transmission power of the machine itself, the shielding range will be correspondingly larger. The field strength of the outdoor mobile phone signal is normally stronger than that of the indoor one. If you use a low-power machine, it will definitely not work indoors. Therefore, in the outdoor transparent environment, it is more suitable to use high-power machines.

In some relatively large production workshops, large conference rooms, lecture halls and other places, medium-power mobile phone jammers can be used to interfere with mobile phone signals. These areas are basically transparent environments. If you use low-power mobile phone jammers , the middle area is easy to leak signals, resulting in blind spots for shielding, and the middle area cannot be installed with low-power shielding devices normally. It is not suitable to use low-power machines in such areas. At this time, you can choose medium-power mobile phone jammers, both The shielding effect can be guaranteed, and the number of installations is relatively small. A little beautification will not affect the overall decoration environment.
The police jammer can selectively open different frequencies according to different usage scenarios. There are also different types of police frequency jammers, such as portable drag box type, vehicle type, backpack type and backpack type. Among them, the portable box-type and vehicle-mounted jammers can quickly replace the modules, but the jammers are not randomly replaced when replacing the RF module. The following points should be paid attention to.
Jammer FrequencyFirst, before replacing the radio frequency module of the police jammer, be sure to turn off the power first. Although the host device has taken sufficient safety protection measures, when replacing the radio frequency module, please be sure to power off the power first to ensure safe operation and avoid cause personal injury, and also to protect the police frequency jammer.
Second, when replacing the radio frequency module of the police jammer, pay attention to the sequence. First, use a wrench to unscrew the connecting feeder from the radio frequency module, then unscrew the screw fixing the radio frequency module, and then remove the radio frequency module from the host. Pull out. During the pull out process, pay attention to the appropriate force, and then insert the RF module to be replaced into the module compartment, pay attention to the direction of the module, and match the power supply interface of the host module to the power supply interface of the module. Use brute force, then secure the module screws and finally screw on the feeders.
