The cell phone jammer can be roughly divided into three grades according to the power. The first grade is the low-power type, which means that the transmit power of each jamming module is below 2-3W. The second gear is the medium power type, which means that the transmit power of the interference module is 10-20W. The third gear is the high-power type, which means that the transmission power of the interference module reaches 50W or even 100W. Different application environments can correspond to mobile phone signal cell phone jammers of different power levels. Then some customers asked, is it effective to install low-power cell phone jammers outdoors?

Under normal circumstances, high-power cell phone jammers are selected for outdoor open areas and large-scale open areas, while low-power cell phone jammers are selected in indoor environments. If you choose the other way around and install the low-power type outdoors, this situation is very rare, and it can only be done in very special circumstances. In most cases, when low-power cell phone jammers are installed outdoors, their effective jamming range is only 2-5 meters. After all, its transmit power is relatively low. If it only interferes with such a small distance, it will definitely not be recognized by customers.

We all know that the actual interference range of the cell phone jammer is closely related to the strength of the mobile phone signal on site. The stronger the mobile phone signal, the shorter the effective interference distance will be. The mobile phone signal strength in the outdoor environment is generally at least 10dB higher than that in the indoor environment. This is why some low-power cell phone jammers can effectively interfere with a distance of more than 10 meters when used indoors. As a result, when they are tested outdoors, they will find that the interference distance will be severely shortened.

When installed and used outdoors, the interference distance is only 2-3 meters. If large-scale coverage is required, it must be densely installed through cellular networking, which is obviously inappropriate. First, it is necessary to purchase a large number of mobile phone signal cell phone jammers, and second, it will bring a lot of trouble to the power supply and installation of the equipment.
