APX-JP-12B 12-Band Mobile Phone Signal Jammer (2-50m)

The APX-JP-12B is a 12-band mobile phone signal jammer with a 2–50 m effective range for meeting rooms, examination halls and secure areas. The extra bands cover more phone and data frequencies than the 8- and 10-band models, blocking calls, messages and data on twelve channels at once.

Its twelve channels cover CDMA, GSM, TD, DCS, TD-F, 3G, 4G, WiFi and three 5G bands, with RF output power of 30–35 dBm per channel. The shielding area of 2–50 m depends on mobile network signal density, so one unit covers a meeting room or an examination hall.

With 60 W power consumption in a 305 × 235 × 60 mm unit at 6.3 kg, the APX-JP-12B is a desktop jammer for fixed installation where the widest band coverage is needed.

Application Scenarios

1) Meeting Rooms & Conference Rooms

For meeting rooms and conference rooms, the APX-JP-12B blocks mobile phone signals across twelve bands, so calls, messages and data cannot interrupt a confidential discussion.

2) Examination Halls

For examination halls, the jammer's 2–50 m shielding range covers the hall, preventing candidates from using phones to communicate or look up answers.

3) Prisons & Detention Centres

For prisons and detention centres, the APX-JP-12B stops smuggled phones from connecting to the mobile network inside the protected area.

4) Government & Secure Facilities

For government buildings and secure facilities, the 12-band jammer blocks mobile signals in sensitive areas where phones must not be used.
