    Hello Warren! Navizon Indoor Triangulation System is the newest development of the Navizon company. They are calling it the first global system of micropositioning which can operate both indoors and outdoors but all its advantages may be fully seen only indoors. It uses GSM, GPS and WiFi signals to make indoor triangulation and locate any smartphones, laptops, tablets and other electronic devices. As you can see, this indoor triangulation system is very precise, effective and impressive. It uses many frequency bands in its work. In order to hide from its ubiquitous triangulation you need to use Navizon Indoor Triangulation System signal jammer because it can effectively block GSM, GPS and WiFi signals at the same time. If you need to jam this system outdoors, you have to use GPS/GSM jammers with WiFi jammers in combination, but for stationary protection use desktop jammer mentioned above.
