Overview

Our Classsroom Cell Phone Jammer is the nemesis of wireless cheating devices such as mobile phones, Wi-Fi, Bluetooth, and electronic watches. It serves as a security guard and purification expert in the confidential meetings and standardized examination venues.

The jammer is an omnidirectional full-band communication signal disruptor, all of which are seventh-generation green signal jammers. It adopts an aluminum alloy casing and has fast heat dissipation. The military-grade anti-drop and anti-collision design has powerful performance. 

And it combines the advantages of portable and desktop jammers, and has the characteristics of easy portability and high-power interference. The total power of 120W can quickly and effectively eliminate signal threats within the interference range. But they only block the reception of on-site mobile phone jamming devices and do not affect surrounding base stations at all.

With its unique and discreet design, this classroom cell phone jammer is ideal for indoor environments like classrooms and conference rooms where blocking cellphone or Wi-Fi signals is essential.

Precautions:

1. Factors affecting the actual shielding range include signal field strength, base station distance, mobile phone format, obstacles, installation height, installation specifications, etc.
2. It is normal for the host to heat up after working for a long time. If the temperature is too high, please turn off the power and contact your local dealer
3. The normal installation height is 1.8m～2.5m, try to choose the place where there is no obstacle between the target shielding area. The wall-mounted installation requires the antenna to be vertically upward. When using on a desktop, the antenna can be folded 90 degrees and then vertically upward. There should be no AC power lines or other audio and video lines within 0.2 meters of the antenna.
4. In order to avoid possible interference with some electronic equipment, please try to keep 1~2 meters above the following common equipment: audio, wireless microphone, radio, computer, TV, Wi-Fi router, Rcied, etc.

Applications:

①Confidential meeting places such as party and government organs and enterprises;

②Courts, detention centers, and large, medium, and small prisons;  

③College entrance examination, high school entrance examination, judicial examination, civil service examination, CET-4/6 and other places where mobile phones are prohibited.
