Whether it is a large signal jammer device or a small signal blocker device, its principle is to interfere with the mobile phone to receive the normal frequency sent by the base station through its own frequency, so that the mobile phone cannot contact the base station, so as to achieve the purpose of shielding. The principle of blocking WIFI is actually that the wifi jammer will send out the corresponding frequency when it is working to interfere with the mobile phone to receive the normal frequency sent by the router so that the mobile phone cannot connect with the router and cannot surf the Internet normally. Wifi signal jammer, which can generate specific electromagnetic signals and cover GSM two frequency bands at the same time. The three main frequency bands of one frequency band of CDMA.
The wireless wifi jammer transmits on three main frequencies to block all nearby wifi network activity, Bluetooth devices and wireless camera signals. Wifi, Bluetooth and espow wireless jammers for worldwide use.
How to choose a suitable wifi signal jammer?
Whether it is used indoors or outdoors, from power matching, and style matching, such as whether hundreds of units can be managed online, unified control, etc. Different needs are naturally different, and the environment for different jammers is different. , according to different signal strengths to match the wifi jammer device, choose the jammer with low power in a small area, choose multiple stacking shields in a large area, or choose a higher power wifi jammer.
At present, the technical routes adopted by the existing domestic and foreign shielding devices are mainly two kinds of co-frequency sound interference and electromagnetic radiation interference.
