High power portable GPS jammer, a powerful solution to completely block all nearby mobile phones, both standard GSM but also newer 3G models, as well as WiFi networks. It can be used all over the world.
Powerful and efficient, this handheld gps jammer disables all nearby WiFi and 3G networks, as well as other mobile phone signals (GSM, CDMA, DCS, PHS bands) without interrupting other electronic devices. Compact in size, with an easy-to-access activation button, which allows users to quickly turn the device on or off for immediate jamming of portable signals.
High quality jammer is the inevitable product of the growth of the security industry because the industry occupies a central position. The known signal jammer blocks the barrier, but also extends the open portable signal jammer, portable jamming, ceiling jammer, electric jammer and others.
The first contact is interference many years ago, when the function is used in some business interference. Followed by the rapid growth in technology, different wireless jammer are opened, using the categories also followed to improve product quality is extended to several industries, airfield hospital, library, college entrance examination hall and and so on.
It is very variable, some people are disappointed; because they expect too much.
In my opinion, that is what it is. As a general rule, and logically, the stronger the network, the more difficult it will be to jam the signal.
on the outside it's not even worth a try, except being glued to the phone you want to jam.
indoors, it all depends on the structure of the building and the strength of the signal it lets through. I have had good results in supermarkets; for example.
in public transport: it also depends on the signal strength at time T; I had excellent results on trains and buses, but not in stations, more in the countryside.
