APX-JP-8B 8-Band Mobile Phone Signal Jammer (2-50m)

The APX-JP-8B is an 8-band mobile phone signal jammer with a 2–50 m effective range for meeting rooms, examination halls and secure areas. It blocks mobile signals across its bands so phones cannot connect inside the protected zone.

Its channels cover CDMA/GSM, TD, DCS/PHS, 3G, 4G, 4G/5G, WiFi, 5G WiFi and 5G, with RF output power up to 36 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 120 W power consumption in a 440 × 135 × 40 mm unit at 3.5 kg, the APX-JP-8B is a desktop jammer for fixed installation where mobile phones must stay silent.

Application Scenarios

1) Meeting Rooms & Conference Rooms

For meeting rooms and conference rooms, the APX-JP-8B blocks mobile phone signals across eight bands, so calls and messages 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-8B stops smuggled phones from connecting to the mobile network inside the protected area.

4) Government & Secure Facilities

For government buildings and secure facilities, the 8-band jammer blocks mobile signals in sensitive areas where phones must not be used.
