GPS jammer suddenly returns you to primitive society

“If the report is accurate, the [North Koreans] may have acquired a more powerful gps jammer, capable of affecting navigation systems over a wider area, (potentially) impacting a host of activities, from intelligence collection to precision weapons applications,” one former U.S. Air Force intelligence officer notes.

Now it appears that North Korea, determined to drive U.S. forces off the Korean Peninsula, may have successfully jabbed at this Achilles’ Heel. Despite Pentagon denials, South Korean military reports contend that covert jammers in the North Korean hilltops likely triggered a U.S. spy plane’s “emergency landing.”“It’s a wake-up call,” said David Last, a British GPS specialist and University of Wales professor emeritus who has consulted with South Korean officials.

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.

In this modern society, with the fast development of internet, the function of computer and mobile phone has developed, too. 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.
