Medium-sized Mobile phone WiFi signal jammer for with jammer radius up to 40 meters
Mobile phones basically use radio frequency signals in a specific frequency range to transmit voice/data through wireless media in order to communicate with other mobile phones. These signals are coordinated by cell towers in the area covered by mobile phones.
In most cases, mobile phones use one frequency to send signals and another frequency to receive signals. The frequencies used by major telecommunications standards such as GSM, CDMA, 3G/4G, DCS, PHS, etc. are fixed and large areas. Therefore, by sending a high-power RF signal that needs to be blocked in the same range as the mobile phone communication signal, it is possible to produce shielding in the mobile phone communication (in a specific area).
To do this, people may need a small device called a'cell phone jammer' (with a transmitter, antenna and other electronic circuits). When someone turns on this device, high-power radio frequency signals are generated and sent out (within a certain coverage area), thereby shielding real cellular voice/data signals, thereby effectively blocking/interrupting them.
30 - 40 Meters Medium-sized signal jammers
This 8-band desktop signal jammer adopts advanced manufacturing technology. In view of the diversity of the signal spectrum, it can meet the signal shielding needs of different users.
