Power level and application environment of wireless signal jammers

Power level and use environment of wireless signal jammer

Wireless signal jammers can be divided into three power levels according to the transmission power. The first level is low power, and the transmission power of each shielding module is below 2-3W; the second level is medium power, and the transmission power of each module is 10-20W; the third level is high power, and the transmission power of the shielding module can reach 50W or even 100W. Different application environments have different requirements for the power level of signal jammers.

High-power wireless WIFI signal jammers are generally used in open outdoor areas and larger spaces, while low-power jammers are suitable for indoor environments. Although it is not common to install low-power jammers outdoors, there are special cases where this is necessary. However, in most cases, when low-power jammers are used outdoors, their effective shielding range is limited to 2-5 meters due to their relatively low transmission power.

The actual shielding range of the jammer is closely related to the strength of the mobile phone signal in the area. The stronger the mobile phone signal, the shorter the effective shielding distance. In outdoor environments, mobile phone signals are generally more than 10dB stronger than indoor ones. This is why some low-power jammers can effectively shield more than 10 meters when used indoors, but when tested outdoors, the shielding distance of low-power jammers is only 2-3 meters.

In actual use scenarios, mobile phones may automatically select multiple channels with different characteristics. There are differences in indoor and outdoor signal strength. Factors such as the ground and metal objects will also affect the signal and produce complex interference effects. Therefore, the performance of the jammer will vary depending on these factors. On-site surveys help determine the signal field strength environment of different frequencies in the area that needs to be shielded, select a jammer with appropriate power based on customer needs, and optimize the working frequency band through instrument measurement.
