In exam halls or confidential meetings, even a single unmonitored phone or wireless device can ruin everything. Cheating, secret recordings, or unauthorized communication don’t just cause temporary disruption—they can lead to complaints, investigations, exam retakes, legal trouble, and serious damage to your organization’s reputation.
This 110W Portable Signal Jammer solves the problem at its root. By completely blocking 2G–5G cellular networks, WiFi (2.4G / 5.2G / 5.8G), and optional V/U walkie‑talkie bands, it establishes a 10–80m controlled signal‑free zone where unauthorized communication is technically impossible.

Why Choose Our Portable Signal Jammer?
-
Standardized manufacturing and testing ensure consistent signal-blocking performance.
-
Professional design for exams, secure meetings, and controlled communication environments.
-
High power output and wide coverage for reliable, long-term operation.
-
Employs UHF jamming technology for complete wireless signal jamming.
-
Modular multi-channel output ensures stable performance and efficient interference.
-
Advanced directional antenna array extends jamming range up to 80 meters (depending on ambient signal strength).
How Does Our Portable Signal Jammer Work?

The S-110W uses a directional antenna array and multi-channel segmented output to generate strong jamming signals across multiple communication bands. This prevents mobile devices, WiFi devices, and other wireless transmitters within the coverage area from sending or receiving signals, effectively isolating them from external networks.
