People have not only regard them as the basic communication tool, they have treated them as the necessity even best friends in their daily life. They can do lots of things in it. Especially when we welcome the coming of smart era, smart machines, smart mobile phones, smart robot, etc. While behind the smart devices, people become more lazy, more indifferent, more cold and more strange. Sometimes we really need such selectable cell phone signal WiFi GPS jammer to get us back to the reality life.The GPS signal jammer works by sending out its own signal on the same frequency as the GPS unit, a noisy signal that prevents it from receiving or transmitting any useful information, either in bursts of sound or a continuous wave.Russia has very advanced capabilities to disrupt GPS. Over 250,000 cell towers in Russia have been equipped with GPS jamming devices as a defense against attack by U.S. missiles. And there have been press reports of Russian GSM jammer in both Moscow and the Ukraine. In fact Russia has boasted that its capabilities “make aircraft carriers useless,” and the U.S. Director of National Intelligence recently issued a report that stated that Russia and others were focusing on improving their capability to jam U.S. satellite systems.Etterretningstjeneste or E-tjenesten, did not believe that the GPS jamming was directed at the country specifically, according to the country’s state-run NKR radio service. East Finnmark is situated along the border with both Finland and Russia.That even state intelligence services have had difficulty in determining the source of the jamming and whether or not it was deliberate, highlights how effective these tactics can be even during an uneasy peace. With electronic and cyber assaults, Russia has found an effective way to disrupt the military and government activities of its regional opponents while maintaining a surprising amount of plausible deniability.GPS disruption isn’t limited to jamming, either. There are increasing reports that the Russians have been expanding their ability to spoof the system’s signals, point receivers at the wrong locations. In June 2017, we reported on the U.S. Maritime Administration's report about such incidents in the Black Sea in which ships’ navigation equipment was showing their location miles inland. Other reports of location errors had earlier cropped up in Moscow among players of the popular cell phone game Pokemon Go, which relies on a mobile device’s GPS-enabled location services.
