At the beginning of the 21st century, cell phone has started its rapid proliferation. Eventually, its ubiquitous status has raised problems such as their potential use to invade privacy or contribute to egregious academic cheating. In addition, public wills were growing against the intrusive disruption of cell phones in daily life. While more and more civilians are suffered from chronically poor reception, such as high frequency noise. Fortunately, Portable Mini Mobile Signal Jammers are an alternative to more expensive measures against cell phones, such as the portable mobile jammers, which are mostly suitable for building a security environment. Cell phone jammers were originally created for the military and law enforcement to interrupt communications between criminals and terrorists. Some were designed to destroy the success of certain remotely explosives. The civilian applications were apparent too. So over time many companies design jammers for government use and at the same time sell them to private entities.
