In the process of consulting us about high-power jammers, some customers often put forward a more intuitive performance index requirement, that is: in the outdoor environment, the distance of shielding the mobile phone signal should reach 50 meters, or one more Level, the distance required to shield mobile phone signals reaches 100 meters. From the customer's point of view to analyze such requirements, the customer's understanding is that since the required shielding distance is doubled, the power of the corresponding high-power jammer should be almost doubled. It can also be inferred that the corresponding equipment cost must be There is a big gap, so, is the final conclusion really true?

The unfortunate result is: the ideas of these customers do not match the reality. In the outdoor environment, the effective distance for shielding mobile phone signals, the nominal distance of 50 meters and 100 meters, is actually not very different. Even for our high-power jammer manufacturers, products that meet the requirements of this index, We group it under the same indicator range.

Shielding mobile phone signals is based on various mobile phone signal shielding equipment. According to the classification method of power, we generally divide them into three categories: low-power, medium-power and high-power. Among them, the low-power type means that the transmit power of each shielding module is about 2-3W, and the main use is in the indoor environment. The medium power type means that the transmit power of each shielding module is about 10-20W, and the high-power type means that the transmit power of each shielding module is above 50W. Both the medium power type and the high power type are used in outdoor environments.

When used in an outdoor open environment, although the nominal distance of medium-power jammers sometimes exceeds 50 meters, in practical applications, due to the influence of the distribution distance of surrounding base stations, they often block mobile phone signals. The distance will be less than 50 meters, and the normal performance is about 20-30 meters. If you want to ensure that the distance of shielding mobile phone signals can reach more than 50 meters in most use cases when used outdoors, you must use a high-power jammer with a module power of more than 50W.

We also need to point out that: when evaluating the distance of shielding mobile phone signals, the value of the distance can only be a relatively broad approximate value, or a macro value, it cannot be very accurate, and the shielding signal is transmitting During the process, it is impossible to precisely locate a certain position. For example: When the shielded signal is transmitted around, its characteristics are somewhat similar to a loud shout. When the sound is transmitted to the outside world, it is definitely unlikely that the sound can be transmitted to a certain specified distance very accurately.
