The higher the output power of the wifi jammer, the better the actual effect, I don't think that is the case. The output power of the wifi signal jammer is in the category of safety output power.
What are the factors that affect the effect of a wifi blocker?
1. Power
Characteristics of wireless antenna radiation (gain, specificity, etc. of the wireless antenna)
2. The method of shielding at work
Nowadays, mobile phones are all analog signals, and the anti-shielding ability of analog signals is very strong. Usually, the technical effect of shielding analog signals with analog signals is weak. Therefore, it is necessary to use analog signals to shield analog signals, and large numbers of the same output power to shield them. The actual effect of shielding the data signal on the mobile phone is completely different from that in the simulation.
3. The room is different from the outdoors. The analysis of the generation, attenuation coefficient and reflection surface of the mobile phone signal and the shielded data signal in the room is more complicated.
4. Before being shielded, the compressive strength and quality of mobile phone signals in the local indoor space will cause great harm to the shield. Different mobile phones have different actual effects. Usually, mobile phones with a strong ability to accept weak data signals can resist shielding. The effect may not be good.
5. The orientation and spacing of the video signal and the orientation of the mobile phone shielding area also endanger the actual effect of shielding.
6. The characteristics of shielding distance and wireless telephone data signal transmission distance. Now, the attenuation coefficient of wireless telephone data signal transmission in free space is used to easily discuss shielding distance. According to the basic theoretical relationship of transmission, every time the electromagnetic wave transmission distance doubles, the signal intensity attenuation coefficient is 6db (the output power of the data signal is reduced by 4 times). Then people take a wireless wifi jammer GSM 800MHZ as an example, if the mobile phone signal strength in a certain area that must be shielded is -60dbm, and the reasonable shielding distance of the shielding device is 12 meters, the change of the mobile phone signal strength will immediately affect the shielding distance. of near and far.
However, the shielding distance of the jammer is not fixed. According to the local signal environment, the stronger the mobile phone signal, the shorter the shielding distance, and the weaker the signal, the longer the shielding distance. Before buying, be sure to measure the signal strength of the place where you use it. If you want to block any signal, you can contact us!
