If it is used in a regular environment, it is not complicated to install and debug the signal blocker. Generally, you only need to turn on the host switch after powering on the device, and use the mobile phone at different positions away from the shielding device to observe the working status of the mobile phone, which can be very intuitive. Determine the interference effect. However, once you encounter a complex usage environment and need to perform signal analysis on site or formulate an adjustment plan, you need to use a spectrum analyzer to help. At the same time, it can also fully reflect the importance of the spectrum analyzer for the installation height of the signal shield.
The complex usage environments we are talking about here can generally be divided into two categories: 1. In the on-site environment, the base station signals transmitted from the mobile phone base stations have various formats and large differences in signal strength, resulting in the interference effect of the signal jammer. Some cell phone signal jammers work very well, but others seem to have no interference at all.
At this time, if there is a spectrum analyzer on site, technicians can quickly know through signal retrieval which format of base station signal is stronger in such a site environment, or analyze and determine which mobile phone frequency band signal jammers Complete signal suppression is not achieved. Feedback of this analysis result to the signal jammer manufacturer will help quickly find solutions to unsatisfactory mobile phone signal interference.
In the on-site environment, the layout of the building is complex, there are many partition walls or obstacles, and the signal coverage of the signal jammer is uneven. In such a field environment, if you have a spectrum analyzer, you can receive the interference signal from the signal jammer through the receiving antenna and display it on the spectrum analyzer, and then observe the amplitude of the waveform in each frequency band or read the signal strength. value, accurately grasp the signal coverage strength of the shielded signal in each area, and further adjust the installation position of the signal jammer or the antenna orientation to obtain the expected signal interference effect in the corresponding area.
