The shielding device is the most important part of your cell phone signal jammer. The right selection of shielding devices can ensure that your cell phone signal jammer works well in all circumstances. There are many different types of shielding devices, such as metal and carbon shields. The metal shield is the most common type and is the best choice for you if you want to find an effective cell phone signal blocker that can block all kinds of signals from phones or similar devices without affecting other equipment nearby.

A high-power signal blocker is designed to block all kinds of wireless signals within its effective range. It means that wherever you place or carry this device, there will be no radio frequency (RF) waves around for others to detect or use their mobile devices. For example: if someone uses WiFi in an office building with a high-power signal blocker nearby, their WiFi connection will not work properly until they move away from its effective range (usually between 10 meters).
