The GPS signal suppression device is the most suitable product for commercial vehicles. You can prevent GPS failures without worrying about someone tracking. During the work of the jammer, the portable WiFi jammer scans from the lower frequency band of the previous communication channel to the high end at a constant speed. When the mobile phone receives a text signal, this scanning speed appears garbled, that is, it is disturbed, and the smartphone cannot check the normal data sent from the base station. Similarly, to a certain extent, mobile phones will not be able to establish contact with base stations.
Mobile phones are experiencing phenomena such as network, no signal, no service system, etc., and cannot be used, so their use is prohibited. When the phone leaves the obstacle area, it can be used normally. The electrical signal sent by the portable jammer is undoubtedly an electromagnetic signal, but in the wifi jammer specialty store, this barrier will not affect any other equipment and data, that is, it will not interfere with other electrical equipment, and it is harmless to the human body.
Mobile phones in some hospital locations may adversely affect precision equipment. Also, ringing phones can be uncomfortable when people around you are quiet. Some people use their mobile phones in places where it is prohibited to carry them. In this case, use a WiFi signal blocker. There will be no phones in the area, and mobile phones leaving the area can communicate.
