What's the Working Principle of Phone Jammers


We all know the role of mobile phone jammer, here we will briefly introduce its principles, so you will understand some of the jammer precautions.

Before that, we talk about the principle of mobile phone (radio communication), as follows: in a certain frequency range, mobile phones and base stations are connected with each other through the radio waves with a certain baud rate and modulation to complete the data and sound transmission.

In view of the above communication principle, the jammers work at a certain speed from the low frequency of the forward channel to the high-end scan. The scanning speed can be generated in the mobile phone message to generate garbled interference,and the phone can not detect the normal data sent from the base station, so that it can not establish a connection with the base station. Mobile phone performance as no signal, no service system and so on. In short, it is like someone talk loudly so you can not hear what your friend said in the phone.Here the 'someone' means the jammer.

It's also the reason why the shielding effect is sometimes bad because the base station is relatively close, or the mobile phone signal is very strong.

In addition, please note that if the you use the small power jammer (such as handheld jammer) to interfere with the large power devices (such as high-power WIFI router, Bluetooth audio equipment, etc.),it will be poor or even can not work. Meanwhile between the jammer and the phone,there should not be something like metal or glass wall which can block the signal transmission.
