Nowadays, there are many hidden dangers in wireless wifi networks. Some professionals want to eavesdrop on private ones, and they can easily eavesdrop through software. If you want to prevent your private data from being leaked while surfing the Internet, you need to install a wifi jammer.
1. The domestic network, due to European restrictions on our exports, has not opened the encryption function, and the transmitted data is not;
2. The inherent loopholes in the security mechanism of GSM and CDMA - one-way, that is, only the network identifies the mobile phone, and the mobile phone absolutely trusts the network, making it possible to pretend to be a legitimate user to intercept;
3. The radio waves emitted by the mobile phone can cross-modulate and transmit the electromagnetic wave information of the surrounding electronic equipment, causing leakage;
4. The mobile phone is just one, and the mobile phone in the call state will send all the surrounding sounds to the receiver; even if the mobile phone is turned off, as long as the battery is not removed, the surrounding sounds can be acquired by the proprietary eavesdropping device one by one;
5. The main technology and internal chips of mobile phones are imported, and it is difficult to guarantee that there are no technical secret doors in these mobile phones. These background technologies include remote switching on and off the phone, reporting the location of the phone without displaying it; making calls unknown to the user, and even recording the content of the call and sending it to a third party;
6. The United States has established a global electronic monitoring network system. People use mobile phones to talk, and almost all of them have to go through "filtering".
The wifi 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. This scanning speed can cause garbled interference in the received message signal of the mobile phone, and the mobile phone cannot detect the normal data sent from the base station so that the mobile phone cannot establish a connection with the base station, and the mobile phone appears to be unable to search the network.
