Take a look at “6 antenna high power adjustable WiFi 3G 4G signal jammer for all mobile phones”, and learn more about this Bluetooth 4G mobile signal jammer, you will find that this Bluetooth 4G signal blocker is a high power adjustable jammer for all mobile phones Designed to block both ordinary 2G 3G 4G mobile phone signals and Bluetooth. This WiFi 3G 4G full cell phone signal jammer has an adjustable design so that operators can decide which frequency bands will all be blocked. And because of the high output power of 15W, the interference radius of all high-power adjustable mobile phone jammers can reach 40 meters, depending on the signal strength in a given area. The car charger also enables the WiFi 3G 4G all mobile phone signal jammer to be used directly in the car.
Mobile phone jamming devices were originally developed for law enforcement and the military, and are designed to interrupt communications between criminals and terrorists. Bombs that bombed commuter trains in Spain in March 2004, as well as explosions in Bali in October 2002 and Jakarta in August 2003, relied on mobile phones to trigger explosives. According to extensive reports, in December 2003, a cell phone wifi jammer prevented an assassination attempt on Pakistani President Musharraf. When President Bush visited London in November 2004, the British police reportedly considered using jammers to protect the President ’s convoy through London.
It comes with a car charger that is easy to carry and operate. When you want to interfere with GPS tracking, please put the car using the jammer in the cigarette and connect the antenna. The GPS signal will be disturbed immediately, and the car using the jammer will start to work with GPS prevention, tracking and positioning prevention functions. Is there working power protection? Of course, there is an overvoltage protection design for interference, which can prevent the danger of abnormal voltage. Seeing the case, there are many heat dissipation holes to ensure a stable working temperature inside. Therefore, GPS jammers can work for a long time and have a long life, and can also have stable performance when working. Moving the antenna away from the jammer is the way to end the interference. If you want to continue, put the antenna back to its position.
After doubting whether you are using your phone for tracking, the first response is to put the phone in airplane mode. I don’t want to scare you, but that won’t work. There are two operating systems in each mobile phone, one for cellular phone flight mode only prohibits the second function, and can do nothing to connect the mobile phone and the network. The network connection is still active. Even if you do not send GPS coordinates, you will still be tracked and discovered. Related to the base station, you have been tracked.
