OEM ODM Mobile Communication Jammer for Examination Halls and Libraries with Adjustable Radius

Basically what it does is block phone signals in places like exam halls and libraries, with a jamming radius you can adjust form 1 to 20 meters depending on the room size. It covers 2G through 5G across 20-6000MHz, so pretty much any modern device is out of range when it's on.

aluminun-alloy casing is IP65-rated, which means it handles dust and moisture better than most indoor units we've seen. We've had these running for months in humid library basements without any corrosion issues. What it also does is use special tech to avoid frequency band interference—something cheaper jammers often struggle with. The built-in directional antenna is wall-mountable, so you can aim it precisely at the target area and leave the rest of the building alone. That 12W total RF output is enough for a standard hall, but don't expect it to punch through thick concrete walls.

It's not really suited for outdoor use or large open spaces beyond 20 meters—the radius is designed for controlled indoor environments. Most buyers go with the wall-mounted setup for permanent installation, though we can do OEM/ODM if you need custom branding or adjustments.

To order, we typically need your target frequency bands confirmed (some regions have specific 5G bands), and we'll quote base on your MOQ—usually 50 units or so for OEM. Lead time is about 20 days give or take, but we usually have stock for standdard models if you're in a rush. COA and SDS are included with every batch, and our company can provide HPLC data on request (check lead time for that).

So anyway, just let us know your exact specs and we'll get you a quote. The 5L drum is easier to handle than the bulk packaing for smaller setups.
