Usually, we receive inquiries from customers asking why your signal blockers are so much higher than those that cost tens of dollars online? So, we unconsciously want to ask, do you think the tens of dollars worth of full band mobile signal blockers sold online are reliable?
Let's get to the conclusion first, it's not reliable! Let's analyze the reasons in detail below.
When a mobile phone is working, it communicates with the base station within a specific operating frequency range.
Given this communication principle, the full band signal jammer scans from the low end frequency of the forward channel to the high end frequency at a certain speed during operation. During the communication process between the mobile phone and the base station, garbled code is formed, resulting in the inability of the mobile phone to communicate properly with the base station. The mobile phone appears to be searching the network, without signal, without service system, etc., in order to achieve interference effect.
The interference range of a full band signal jammer depends on the transmission power of each module of the full band signal jammer and the signal field strength of the base station used.
In theory, the higher the transmission power of a full band signal jammer, the larger the interference range.
The stronger the signal from the base station to the location of use, the smaller the interference range of the full frequency signal jammer.
A full frequency signal jammer that can be purchased online for a few hundred yuan usually has fewer modules and lower transmission power, which can only interfere with one or several frequency bands, and the interference effect cannot be guaranteed. The frequency band signal blocker cannot interfere with mobile phone signals.
Signal jammers also emit electromagnetic interference signals. The carrier frequency of this signal is the same as that of the base station signal. Therefore, when receiving signals, mobile phones may form garbled interference. Mobile phones are unable to detect which are normal data sent by the base station and which are interference signals, effectively blocking the normal operation of mobile phone signals. If you want to purchase a reliable full band signal shield, it is best to choose a professional full band signal shield manufacturer.
