Pocket mini jammer. It has many advantages:First of all, the design of this device is very portable. It has very small size (95mm*48mm*17mm), can be easily put into pocket or backpack. Second, the device has a very strong concealment. The device looks like a portable power source, can ensure that you are not easily perceived by others during your use. Third, although the device is very small, but it can also jamming multiple signals. Whether you need to block cell phone signals or WIFI signals or GPS signasl, this device can do it.
The device is one of the most popular handheld jammers. it is often used in classrooms, libraries, conference rooms, cinemas and so on. Because this device is small in size and easy to hide, so it is very popular among customers,It ’s worth getting started, you can try it if you are interested.
It also can be used to protect VIPs and groups, military security forces, special police forces, bomb squads, counter-terrorism forces, anti-drug forces, anti-riot forces, anti-explosive operations teams, checkpoints, hostage negotiations, border control, cars, trains, buses and more Most of them are locally engaged in these relatively hidden activities for a long time. The built-in Ni-MH metal hydride 2000mAH battery can work for more than 8 hours. This jammer is worth a try.
To understand how a jammer functions, we must first understand how the global positioning system (GPS) works. A GPS tracker receives microwave signals from an array of satellite transmitters orbiting the Earth at an altitude of approximately 20,200 km. Once the tracker receives signals from four or more satellites, it determines its position through a series of time calculations and trilateration.
A GPS jammer is a device used to conceal one’s whereabouts by sending radio signals with the same frequency as the GPS device. Once this occurs, the GPS device is unable to determine its position due to interference.
The GPS jamming unit itself is typically a small, self-contained, transmitter that generates a 1575.42 Mhz interference signal over a 5 to 10 meter radius.
Typically, the user plugs the car gps jammer into a cigarette lighter and places the unit close enough to a GPS tracker to disrupt the GPS satellite signal. Once powered up, they become fully operational in less than 20 seconds. The relatively low power and quick start up time allow the jammers to be used only when required. Criminals will switch them off as soon as possible to avoid detection. These jammers can be purchased cheaply on the Internet for less than $100.
