Why does the mobile phone still have a signal after the wireless jammer is turned on

Why does the mobile phone still have a signal after the wireless 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 signal 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: Different mobile phone shielding effects are 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 jammer. 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.

Install jammers scientifically and effectively Persons detained in prisons, detention centers and other supervision places are not allowed to exchange any information with the outside world without permission, especially they are absolutely not allowed to carry or use mobile phones. Important information is likely to be leaked and cause serious consequences. Supervision sites require jailhouse jammers to carry out scientific and effective control and prevention, and

eliminate potential security risks caused by illegal use of mobile phones. Product features of jail cell phone jammer: ①Effective segmentation, only interferes with the downlink and does not interfere with the base station; ②Imported chips ensure quality and stability; ③Built-in power supply prevents criminals from maliciously destroying and guarantees the service life of the machine; Intermittent and sustainable work; ⑤ Green and safe, no threat to health. When installing the jail blocker, in order to shield the inner area of the building, it is necessary to consider how far the residents (schools) and other public facilities around the building area are, and also refer to the distance and signal strength of the surrounding communication base stations, so as not to affect Normal communication of cell phone signals in surrounding utilities. At the same time, the requirements for full coverage and shielding of mobile phone signals within the scope of the detention center should also be considered. Large-scale outdoor detention center jammers can be used to evenly arrange and cover the walls to ensure full shielding of mobile phone signals in the required area. At the same time, the blind spot and

leakage point that may exist in the building of the detention center is installed in the supplementary manner, so as to give full play to the product performance and greatly improve the effect of the detention center shield.
