Usually we will receive inquiries from customers, saying how is the full-band signal jammer in your home so much higher than the hundreds of dollars on the Internet? Therefore, we unconsciously want to ask, do you think the full-band cell phone signal jammer that costs hundreds of dollars on the Internet is reliable?
Let's talk about the conclusion first, it's not reliable! Next, let's analyze the specific reasons.
When the mobile phone is working, it communicates with the base station within a specific working frequency range.
In view of 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 the working process. In the process of communication between the mobile phone and the base station, garbled characters are formed, causing the mobile phone and the base station to fail to communicate normally. The mobile phone appears to be searching for the network, no signal, no service system, etc., so as to achieve the effect of interference.
The interference range of the full-band signal jammer depends on the transmit power of each module of the full-band signal jammer and the signal field strength of the base station in use.
Theoretically, the greater the transmit power of the full-band signal jammer, the greater the jamming range.
The stronger the signal from the base station to the use site, the smaller the interference range of the full-band signal jammer.
The full-band signal jammers that can be bought for a few hundred dollars on the Internet generally have fewer modules and lower transmit power, and can only interfere with one or several frequency bands, and the interference effect cannot be guaranteed. The frequency band signal jammer cannot interfere with the mobile phone signal.
If you want to buy a reliable full-band signal jammer, it is best to choose a professional full-band signal jammer manufacturer. As a professional manufacturer focusing on mobile phone interference for 17 years, topsignaljammer Technology Co., Ltd. has many years of experience in product development and production, as well as decades of experience in on-site survey, deployment, installation and acceptance.

The signal jammer will also emit electromagnetic interference signals. The carrier frequency of this signal is the same as that of the base station signal. Therefore, it can form garbled interference when the mobile phone receives the signal. The mobile phone cannot detect which are normal data sent by the base station and which are It is an interference signal, effectively blocking the normal operation of mobile phone signals.
