Ensuring no mobile communications occur within the vicinity of critical infrastructure keeps vandalism attempts and terrorist activities at bay. These devices act as a security enhancement.
Key Specifications
Core Features Vary Based on Usage These devices typically cover several frequency bands, isolating numerous mobile networks and wireless communication types. Most models range from 300 MHz to 3 GHz. This guarantees broad-spectrum jamming for various cell phone and GPS signals. The blocking range also varies by form. The handheld and desktop jammers range between 5 and 100 meters. However, larger installations can jam signals over several kilometers. Signal power output is another core specification. Signal strength is critical in blocking range and effectiveness. Most GSM signal jammers have output powers between 10 and 30 watts. Power source indicates whether the blocker is portable or fixed. Many portable jammers are equipped with rechargeable batteries, while desktop and custom blockers are powered by AC sources.
How To Install/Use
GSM signal jammers and blockers require careful placement in the right areas for effective signal isolation. Here are several steps for users to take when using these devices. Identify the Area to Jam:The first step in using a GSM signal jammer is identifying the area needing signal blocking. This could be a meeting room, vehicle, or particular outdoor space. Choose the Right Device:Pick out a jammer based on the kind and range of signals that need to be blocked. Handheld jammers are ideal for portable use, while desktop jammers should be used in fixed locations. Several high-powered jammers can be mounted outdoors for wide-area coverage. Proper Placement:Ensure that the signal jammer is placed in the middle of the area needing isolation. In large rooms, this may mean moving it several times before the jammer can cover the full space. For outdoor settings, mount wireless jammers at vantage points for best performance. Turn On/Adjust Settings:Once the jammer is in position, turn it on and adjust the settings as required. Many devices will let users control power output levels or switch between different frequency bands.
