It is understood that mobile phone signal jammers on the market can limit mobile phone signals that are 500m away from the launching station and have a radius of >20m. The shielding radius is adjustable, it only shields the mobile phone signal without affecting other electronic devices. Save power, the power is 20W-480w.
When the mobile phone works, it is within a certain frequency range, the mobile phone and the base station are connected by radio waves, and the data and sound transmission are completed with a certain baud rate and modulation method. In view of this communication principle, the mobile phone signal jammer scans from the low end frequency of the forward channel to the high end at a certain speed during the working process. The mobile phone is manifested as a search network, no signal, no service system and other phenomena.
The standard mobile phone signal jammer can shield all the 2G 3G 4G signals, 2.4G WIFI signals and Bluetooth signals under all three operators of China Mobile, China Unicom and Telecom. Its principle is to interfere with the mobile phone receiving base station through its own frequency. And the frequency sent by the wireless router, so as to achieve the purpose of shielding them. Their frequencies are as follows:
1. CDMA frequency band transmission frequency 870-880MHz
2. DCS/PHS frequency band transmission frequency 1800-1920MHz
3. GSM frequency band transmitting 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 transmitting frequency 2550-2660MHz
