Laws about Cell Phones jammer and GPS Equipment 

In recent years, the number of websites offering “cell phone jammers” or similar devices designed to block communications and create a “quiet zone” in vehicles, schools, theaters, restaurants, and other places has increased substantially. While these devices are marketed under different names, such as signal blockers, GPS jammers, or text stoppers, they have the same purpose. We remind and warn consumers that it is a violation of federal law to use a cell jammer or similar devices that intentionally block, jam, or interfere with authorized radio communications such as cell phones, police radar, GPS, and Wi-Fi.Despite some marketers’ claims, consumers cannot legally use jammers within the United States, nor can retailers lawfully sell them.

As it was mentioned above cell phone signal blocker perfectly works with mobile phones. It blocks the GSM standard completely, which is using two frequencies: 850/1900 MHz for USA, Canada and Latin America as well as 900/1800 MHz for Europe and Asia. But mobile devices can operate not only those two frequencies. CDMA and 3G are also a really popular data transmission standard for smartphones and other portable gadgets. Jamming CDMA, 3G and GSM will not only give tranquility by blocking the reception of jib-jabbers around you. It will also make you invisible for modern tracking techniques such as cell tower triangulation.

Blocking the GPS and GLONASS frequencies is also meant for tracking prevention. Those global positioning systems are frequently used for these purposes due to a high autonomity of the gadgets used for tracking. Those trackers can live for months because they consume little energy. GPS uses three channels for positioning and their frequencies are: L1 – 1575.42 MHz, L2 – 1227.6 MHz, L5 - 1176.45 MHz and they are totally blocked. GLONASS is broadcasting in two channels: L1 - 1602-1615 MHz, L2 - 1246-1256 MHz and cell phone signal jammer frequency scrambler will also stop it.

Still, Humphreys kept on jamming for another year until two county sheriff deputies pulled him over. They were able to confirm his use of the cellphone jammer before they even searched his vehicle and found it behind a seat cover. As they approached his SUV, their two-way radios were disconnected from their dispatcher.
