20–50m range jammers offer balanced coverage for medium-sized spaces. They block mobile, GPS, WiFi, and 5G signals, ensuring privacy and control. This range is ideal for offices, exam halls, classrooms, and small conference rooms where stability matters. Unlike compact 10–15m models, these devices provide extended coverage without reaching the scale of high-power units. At JammerX, you can choose from portable Jammers like Iron 12 and desktop Jammers like Shield 6 in the 20–50m range.

In addition, models such as the Shield 8 Indoor Jammer deliver reliable performance for all environments. Visit our Blog to explore practical use cases and tips for choosing the right jammer.
