  In terms of sound signals, this seems to be a good signal shielding method.Put the mobile phone in a closed iron box, and soon the mobile phone will enter a state of no service.Of course, this method is definitely not feasible.Make each test room into a metal-enclosed classroom Obviously impractical, so what other methods can be used to achieve signal shielding simply, quickly and efficiently? We can imagine such a scene: in a very noisy factory, A tries to talk to B, but the surrounding noise is too great, B can only see A‘s mouth, but does not know what A is saying.

Jammer with portable design and rechargeable battery power

  Maybe now some people know little or nothing about it and don‘t realize how serious the problem is.With a portable design and rechargeable batteries for power, you can easily take the signal jammer where you want.No matter what you do, you feel like there‘s another eye looking at you.

  Various methods of signal shielding In middle school physics, we have learned about metal shielding.In the process of signal transmission, interference is formed, so that the mobile phone cannot detect the normal data sent from the base station, and thus cannot establish a connection with the base station, showing a state of no signal and no service.Do Prisoners Have Cell Phones During the working process, scan from the low frequency band to the high frequency band of the channel from the base station to the mobile phone at a certain speed, and receive messages on the mobile phone.So what about electromagnetic signals? The answer is yes.

  Active trackers use GPS to determine a location and transmit that location over a cellular connection, while passive trackers record and store location data.If you use the above method to find seriously or did not find, that also do not be discouraged oh, teach you a simple and rough method.Most GPS jammers are very small, so don't overlook any potential hiding spots.Note that trackers can be dirty and hard to see.Specialized equipment, such as electronic sweepers or bug detectors, may also be required in cases where simple visual inspection is inadequate.

  GPS locator is generally divided into two kinds, wired and wireless, and in the wired locator, the car GPS locator and the two-wheeler GPS locator installation position is different, but first of all, we should be clear, wired locator line, what is the line. Common vehicle positioner, generally up to 4 lines, in the design process, usually with different colors to distinguish. Take several meters of EV41 vehicle positioning terminal as an example. Red and black are positive and negative poles of power supply respectively, orange is ACC or key wire, and yellow is oil breaking wire. Knowing which vehicle interfaces each of the different colors of the wire will connect to, we can look at the differences in the installation positions of cars and two-wheelers.
