With the continuous development of science and technology and the realization of the information age, the wireless Internet, as a symbol of informatization, is considered to be more and more inseparable from the wireless wifi network. It has also become one of the indispensable tools in people's daily life and works.
Signal transmission between wireless networks is transmitted through routers, which are communication signal relay stations in wifi communication. wifi has brought convenience to my life.
The current wifi jammer is full frequency bands, which can block all 2G 3G 4G signals, 2.4G WIFI signals, and Bluetooth signals under the three operators of China Mobile, China Unicom, and China Telecom. To interfere with the mobile phone to receive the frequencies sent by the base station and wireless router, so as to achieve the purpose of shielding them.
The specific interference frequency bands of the wifi signal jammer are as follows:
1. CDMA frequency band transmit frequency 870-880MHz
2. DCS/PHS frequency band transmission frequency 1800-1920MHz
3. GSM frequency band transmission frequency 925-965MHz
4. TD-SCDMA frequency band transmission frequency 2005-2035MHz
5. WCDMA/CDMA2000 frequency band transmission frequency 2110-2175MHz
6. 2.4G frequency band transmission frequency 2400-2500MHz
7. 4G1 frequency band transmission frequency 2300-2390MHz
8. 4G2 frequency band transmission frequency 2550-2660MHz
