Import Adjustable 4 Band Desktop Mobile Phone Jammer — Buy in Bulk from Supplier in China

The Adjustable 4 Band Desktop Mobile Phone Jammer from Jammer Group is a signal-blocking device designed to disrupt mobile communications across four frequency bands. It features adjustable jamming strength, allowing users to tailor interference levels to specific security needs. The unit operates in environments where controlled signal suppression is required, with a compact desktop form factor for easy deployment in offices, examination halls or secure facilities.

Constructed for continuous use, the jammer targets GSM, DCS, CDMA and 3G bands with a typical output power range of 5W to 10W per band. Standard models cover frequencies from 850 MHz to 2100 MHz, with typical shielding effectiveness of 30 dB to 40 dB within a 10 to 40 metre radius, depending on local signal strength and obstacles. The housing is usually aluminium or ABS plastic for durability and heat dissipation, with standard cooling via internal fans to prevent overheating during prolonged operation.

Common applications include preventing cheating in exams, securing confidential meetings or restricting mobile use in sensitive areas like prisons or military sites. Buyers typically source these devices with FOB or CIF terms from Chinese suppliers, with packaging designed to meet air or sea freight standards. Lead times and MOQs vary by supplier and should be confirmed directly with Jammer Group for accurate planning.
