Indoor Cellular Signal Jammers

The indoor cellular signal jammers, or cell phone jammers can disrupt mobile phone communication. They support jamming twelve frequency bands in 2G/3G/4G/5G network modes. The devices won't interfere to other electronic products which don’t use cellular signals, and do no harm to human beings.

1. Support jamming 12 frequency bands of all network modes (2G/3G/4G/5G).

2. The device synchronizes with the time slots of 5G, TDD-LTE and TD-SCDMA networks, and only jams downlink signal without interfering to operator’s base stations.

3. The synchronization sensitivity is -110dBm.

4. The antennas are external and removable.

5. Models with different channel powers are available (eg. 2W/channel, 5W/channel, 20W/channel).

6. The device has a slow start design which can avoid the phenomenon of IDE ignition. The slow start time is less than 3 seconds, and the jamming effect can be achieved within 120 seconds after powering on the device.


Application Scenarios


The jammer is suitable for small and medium indoor spaces such as conference room, court, church, library, school, examination room, cinema, hospital, gas station, oil depots, prisons, securities, command center and so on.
