Customizable Multi-Band Frequency Signal Jammer for Conference Room Library Court

It takes about 8-10 weeks form order to shipping for a fully custom run—metal shell, 190×57×116mm, and adjustable range from 100 up to about 400 square meters depending on how dense walls are. We basically cover GSM, CDMA, 3G through 5G, and both 2.4 and 5GHz WiFi bands with multi-frequency blocking; it's not a single-band toy.

You'll want to mount it at roughly 2 meters height for best coverage, and keep the nearest base station around 200 meters away or so (closer than that and you might not get full suppression). 100% tested before it ships, every unit—no one's skipping QC here. That 45-60°C operating range means it can sit in an unventilated equipment closet without cooking itself.

Courts and libraries buy most of these, also some government conference rooms where off-the-record meetings actually need to be off the record. our company can do ODM/OEM on the housing color and power supply labeling (usually 2-4 weeks extra for that). But it's not designed for outdoor permanent installs—the metal shell handles indoor use fine, but weather sealing isn't there.

No interference with nearby computers or TVs somehow—what it does is block the handset-to-tower link specifically, not blast everything in the room. One buyer wanted it for a prison visiting area and teh range held steady at 200 square meters even with metal furniture everywhere; we don't have perfect specs for every layout though.

Any cancellation after production starts is forfeited because we build to your exact frequency and range specs. MOQ is around 50 units for a custom batch, but we can do smaller test orders with standerd tuning if you just need a handful to validate placement. Prices vary by quantity obviously—bigger order drops per-unit cost.
