Product Description

LED Display New Generation Handheld Signal Jammer - Wide Shielding Range for Classroom Mobile Phone Restriction & Exam Anti-Cheating

Core Product Features

Full-Spectrum Mobile Signal Blocking

Covers all mainstream student mobile communication signals: 3G/4G/5G cellular networks, 3.6G & 5.8G WiFi, Bluetooth and walkie-talkie signals. Effectively prevents students from secretly making calls, sending messages, searching exam answers or sharing test content via phones in classrooms and exam halls.
Multi-RF Signal Suppression

Blocks GPS L1/L2/L5 positioning, wireless hidden spy cameras and remote control frequencies (315MHz, 433MHz, 868MHz). Eliminates hidden wireless cheating devices, such as wireless earpieces and mini spy cameras used for exam fraud.
Adjustable Shielding Coverage

Effective jamming distance adjustable from 5 to 30 meters, supports simultaneous multi-frequency signal blocking without mutual interference. Flexible for small regular classrooms and large unified exam venues of different sizes.
Built-In LED Digital Display

Clear LED screen shows real-time remaining battery power and working frequency bands. Teachers and administrators can quickly check the device's running status conveniently during classes or examinations.
Stable Stock & Smooth Delivery

Latest upgraded model with continuous ready stock. Expedited door-to-door delivery available to schools across Thailand, Vietnam, Indonesia, Mexico, Colombia, Guatemala and other regions. Complete customs documents provided for school and education department bulk orders.
Tropical Heat Resistant Design

Optimized heat dissipation structure ensures stable long-hour continuous operation under hot tropical weather. Suitable for non-air-conditioned classrooms and open-air exam venues in high-temperature tropical countries all year round.
Custom Frequency & Education Project Support

Frequency bands can be customized according to local national communication standards. One-stop OEM & ODM customized solutions for primary schools, high schools, universities and local education authority anti-cheating procurement projects.

Application Scenarios

Specially designed for campus mobile phone management and exam anti-cheating work: Daily teaching classrooms, midterm & final exam halls, college entrance examination venues, student self-study rooms, campus lecture halls, campus competition examination rooms, training institution testing classrooms.
