Sometimes the signal is necessary, but sometimes it is unnecessary. Sometimes GPS can help people, and sometimes GPS is bad, for example, when it is used for tracking, so GPS Jammers are also used. use.
The current society is developing faster and faster, and the most obvious thing is the progress of science and technology. It is inevitable that the 4G era will replace the past 3G and 2G. Now that 4G hasn't covered the heat, 5G is coming up again. However, 4G signals still exist as the mainstream. So, can the test room signal shielding shield 4G signals? This is a very critical issue. In fact, the new test room signal jammers currently on the market have been upgraded, and shielding 4G signals is almost standard. However, some of the cheaper test room signal jammers currently on the market can only shield 2G or 3G signals.
The rapid development of these operating industries, mobile phone GPS is becoming more and more accurate, dual-frequency GPS is also widely used in mobile phones, which facilitates life but also exposes the location. GPS signal jammers can be used for safety. This way, you can prevent someone from getting the location. So you know How to quickly track the GPS signal of a mobile phone.
People who don't understand this industry are likely to be fooled very easily. The test room signal jammer that shields 4G signals must have at least eight antennas. At present, eight-wire shields are divided into two types, one with an external antenna and the other with an internal antenna. The two are well distinguished. The one with antennas is similar to routers, but there are more antennas on them than routers. The built-in one is as big as a set-top box. Just plug it in and it can be used. Most eight-wire GPS jammers can shield multiple types of signals. Some of them can even shield 5G signals. The 4G era will eventually come to an end, but we have always been at the forefront of technology. In order to help our customers solve their problems, we built a space for shielding 5G signals in the new signal jammers. In this way, even if the 4G era is over, there is no need to replace hardware facilities.
The signal of the mobile phone is shielded from the general location and cannot be sent out, so shielding the signal of the mobile phone is not much different from shielding the GPS.
