Wireless signal jammers can be divided into three levels according to the power size, and different application environments can use different power levels of shielding. One is the low-power type, that is, the transmitting power of each shield module is below 2-3W. The second is the medium power type, the transmission power is 10-20W. The third is the high-power type, that is, the transmitting power of the shielding module reaches 50W or even 100W. signal jammer
High-power wireless signal jammers are typically used in outdoor open areas and larger open areas, while low-power types are used in indoor environments. In most cases, when the low-power network shield is installed outdoors, its effective shielding range is only 2-5 meters, after all, its transmission power is relatively low.
Power Strength: The power strength of the jammer is one of the key factors that affects the shielding range. Typically, the greater the power, the wider the shielding range. High-power jammers can cover a larger area and have a stronger impact on the target signal.
Frequency range: The frequency range of the interference signal emitted by the jammer also affects its shielding effect. If the jammer’s frequency range closely matches the frequency of the target signal, its shielding effect will usually be better.
Antenna Design: A jammer’s antenna design also affects its shielding range. A quality antenna design can improve signal transmission efficiency and coverage, thus extending the jammer’s shielding range.
Environmental factors: Surrounding environmental factors, such as buildings, topography, weather conditions, etc., will also affect the shielding range of the jammer. For example, dense buildings may impede the propagation of signals, limiting the jammer’s shielding range.
Target signal characteristics: The shielding effect of the jammer also depends on the characteristics of the target signal, including its power, frequency, modulation method, etc. Different types of target signals may respond differently to the jamming effects of the jammer.
Electromagnetic interference environment: In some cases, the surrounding electromagnetic interference environment may also affect the shielding range of the jammer. If there are other interference sources, it may interfere with the normal operation of the jammer, thereby reducing its shielding effect.
