Application of signal jammer in the world
Drone jammer be used in RussiaRecently, one of Russia’s biggest weapons maker - “kalashnikov” konzern “army” held in Moscow oblast international military technology BBS exhibited for the first time a specially designed to shoot down drone type electromagnetic gun - REX - 1 against uav electromagnetic gun.
One prominent feature of the electromagnetic gun is that it can not only disable unmanned aerial vehicles, but also disable explosive devices that can be detonated by remote control such as telephone or text messages. The electromagnetic gun can block all external signals so that the engineers have enough time to arrive at the site, dismantle the explosive device and eliminate the threat completely.
The electromagnetic gun can also shield all wi-fi, 3G and 4G communication signals within a radius of two kilometers by emitting an invisible electromagnetic beam. These functions are what the current counterterrorism operations require.
It is reported that the British government to popularize this technology, can let smartphone into the car automatically entered into a state of not connected to the Internet, and both the Internet and telephone network, cannot use. That would prohibit drivers from using their phones while driving. But others have raised questions about the wifi jammer in the car, making it impossible to use the phone.
Cell phone jammer in prisonsIn the face of such high volume of illegal communications devices in prisons, it is astonishing that interventions such as signal gsm jammer technology are not already in use in prisons.
Stopping drones is difficult. “Technological solutions to detect and disrupt drones are in their infancy,” Rosenstein said, adding that the Justice Department supports regulatory changes that would make it easier to deploy interdiction technology and cellphone jamming.
Phones are attracted to a fake network. It is selective - staff or nearby residents’ phones can be put on an unaffected “white list”. Success can be quantified - phones, and their owners, can be identified. Illicit phones can be monitored rather than blocked. It is more expensive than blanket jamming.
The test was conducted to determine if micro-jamming could prevent wireless communication by an inmate using a contraband device at the individual cell housing unit level
