Are Frequency Jammers Legal?

Reading about devices that can disrupt mobile and internet signals might have you intrigued and considering buying one of these devices for yourself. This is actually a pretty common thing for people to want since jammers have a lot of benefits that they can provide and these benefits are quite well documented for everyone to look into.
