Do you know what the shielding effect of the wireless WiFi signal jammer is related to?
The function of the wireless wifi signal jammer is to shield the signal, and it is used in many occasions. The most common use case we come into contact with is the examination room. When we use the wireless signal jammer, you will find that within a certain space, as long as you turn on the switch of the wireless signal jammer, there is no way for everyone's mobile phone to search for the signal, that is, if When you use a wireless signal jammer, you cannot use your mobile phone. So do you know what the shielding effect of the wireless signal jammer is related to? Let's find out together!
The power of the wireless signal jammer is certain. In a space without obstacles, the shielding range is determined by the path attenuation of the received signal and the signal level of the receiving base station. In order to realize the interference of the wireless signal jammer on the mobile network, it must be ensured that the signal field strength emitted by the wireless signal jammer is greater than the field strength in the interference area, because the closer the base station, the stronger the field strength and the shielding effect will be attenuated. On the contrary The farther the interference location is from the base station, the better the shielding effect of the wireless signal jammer will be.
It can be seen that within a certain power range, the shielding effect is mainly determined by the field strength in the interference area. No matter how large the power of the wireless signal jammer is, as long as the transmission power is a fixed value, the strength of the interference signal will increase as the distance increases. will gradually decrease, thus losing the shielding ability. Therefore, the shielding effect of the wireless signal jammer is related to the output power and the signal strength of the base station.
The reason why the mobile phone still has a signal after the wireless WiFi jammer is turned on?
After using the wireless jammer, if you want to know how it works, it mainly depends on whether the mobile phone shows a signal. If the signal is not displayed, the masking was successful. But what should I do if the mobile phone has a signal after using the wireless jammer? What is the reason? We can solve this problem by judging the following phenomena:
Phenomenon 1: If the call can be connected normally, it means that effective shielding has not been achieved in the shielding area. If there is no signal after the mobile phone is close to the wireless jammer, it means that there are base stations or signal amplifiers distributed there. In such a situation that the on-site shielding requirements cannot be met, some high-power shielding equipment can be added.
Phenomenon 2: The shielding effect of different mobile phones is good or bad. It shows that some mobile phones have relatively strong anti-interference performance, and such things will happen to mobile phones with high sensitivity.
Phenomenon 3: The mobile phone seems to have a signal, but the call cannot be made, indicating that this is a false signal. In fact, the mobile phone has been blocked, and there is no timely response. Just turn on the mobile phone data again, or make a call, and then find that the data signal turns gray.
These reasons may cause the mobile phone to still have a signal after using the wireless cell phone jammer for sale. It mainly depends on the signal strength of the scene. Where the signal is strong, the shielding distance of the wireless jammer will be shortened, otherwise the shielding effect will be very good. Therefore, you must adjust it when using it, and control the distance from the mobile phone if necessary.
