Radio frequencies are given off by nearly all cell Signal Blocking Cases, and these radio frequencies can be detected with the proper equipment. The most important factor to take into account when choosing a bug detector is finding equipment that repeatedly locates several types of spy devices. Different types of spy bugs give off a large range of frequencies and it is important for your detector to be able to locate as many devices as possible. The larger the range of frequencies detectable, the more likely your detector will locate hidden spy bugs. It is important to find a model that has a good display of the frequency that is being read and the strength that it is reading at.

Additionally, cell phone booster is not able to boost signal for long distances outside, as this could cause interference with cellular towers, and thus falls within the domain and jurisdiction of the cellular providers. There are a few things to keep in mind when choosing a cell phone signal booster.
