Near the college entrance examination, many schools are busy preparing for the examination. According to the experience in the past few years, the problem of "cheating" has always been a headache. So, how to choose a reasonable signal jammer to avoid some problems in the exam?

You can see the actual floor area to be shielded on site. The working range of different interference devices is also different, which can be selected according to the size of the classroom area. It can also test the signal strength of the site. The actual signal strength is more related to the signal amplifier installed nearby and the base station. At this time, it is recommended to select high-power interference equipment to improve the effect of interference signal. Due to the different models of signal jammers, the parameters set by different shielding machines are different, and the application environment is also different. Be optimistic about the installation position in advance, and select special signal interference equipment to reduce uncertain factors and ensure to play a greater role. When the equipment arrives, detect the jamming equipment in advance. When selecting the signal jammer, test the on-site shielding effect in advance. Use several mobile phones of different brands and operators to estimate the working range of the jamming equipment.

When selecting signal jammer, repeatedly verify whether it meets the shielding requirements and whether it works stably for a long time in combination with the current situation. The above is my summary of signal jamming equipment. I hope it can help you.
