Up to 40m jammers provide strong coverage for medium to large spaces. They block mobile, WiFi, GPS, and Bluetooth signals, keeping areas secure and private. This range is ideal for exam centers, conference rooms, offices, and training halls where reliable control is required. Unlike short-range models, 40m jammers extend protection across larger areas while maintaining stable performance.
