A Jammer is, fundamentally, a signal blocking device, which transmits synchronized radio waves on the same frequency range of the device that one needs to blur, therefore preventing devices from transmitting data in the chosen area.

First of all, just to make it clear, there are no such things as universal jammers, capable of blocking all of the existing frequencies. The only device that comes close to such a product is what we, usually, call a Bomb Jammer. But, there are several issues that have to be taken into account before handling bomb jammers.

Secondly, there is the size issue, because they might be a little bulky, since you cannot hold it in your hand or hide it in your pocket, either. The smallest, yet the most complete one can be carried in a backpack, even though its antennas do exceed your height!

In spite of everything, there is one thing that must be said out loud; there is surely no need to jam every frequency, unless you are part of a government body, in which case it may be understandable.

So, let´s skip to the third point. Before proceeding with the purchase, make sure you know exactly the distance and the jamming range that need to be covered. The output power of a jamming device is measured in terms of wattage (W), therefore the more Watts a cell phone jammer owns, the more the distance covered and its jamming range.

And finally, although it might seem less important than the previous 2 points listed above, there comes the installation and the dissipation(cooling system) of the jamming device. Depending on where the device will be installed, you may get the best out of it and exploit it to the nth degree. Moreover, the potential overheating of a car jammer results in a reduction of its performance, apart from being detrimental to its internal components.

Hence, it is highly recommended that you, absolutely, do not underestimate the importance of this last factor.
