Jamming range is one of the most frequently discussed topics on internet concerning different jamming devices. Every jamming device has a different working range and it’s thus really important to know a couple of things on this aspect if you’re sure that you need to purchase one of those blockers. The fact is that you can find the information you have been looking for on internet, so in this article we will try to explain why the jamming range stated in the manufacturer’s specification sheet is often different from the actual working range.
As a beginning, it should be mentioned that as soon as those jamming devices are created they get tested. Along with all the necessary tests such as transmitted frequencies, battery life and so on, the jamming range is also tested. And those devices are tested most often on empty field– that is why manufacturers always claim greater range than the actual. It’s obvious that the range is wider when there are no buildings and different concrete structures. But the fact is that most of us are living in big towns or cities and we are often surrounded by high buildings. This explains why you don’t have to be surprised if the blocking device you got can’t block the signal of a phone located 20 meters from you. There might be a lot of reasons for this, but the most reasonable one should be that the buildings making the range smaller as obstacles.
Certainly, there are many different types of signal jammers available on the market, so if you want to block any signal within a really big range then you will spend a small fortune for one of those devices. However if you have a tight budget and won’t be able to buy an expensive jamming device, then it’s okay you can get one of those low-powered devices. And they have a really decent working range especially if your main target is to block the people in the surrounding areas. In this case, I think an actual working range of around 5 meters will be quite enough, especially when you are using it on the bus and want to make people shut up for a couple of minutes. Then a signal jammer like this will definitely be helpful.
Also you should pay special attention to their battery life when it comes to portable/handheld jammers, because if you don’t have lots of money this is actually the most important thing you need to look for, along with the frequencies and jamming range. Every single jamming device is doing a great job and you should keep in mind that this is the easiest way to get people stop talking on their mobile phones. It’s necessary to have a knowledge of some basic things on those blocking devices, and in this way you can make the choice easily when actually purchasing one.
