Signals are sometimes necessary, but sometimes unnecessary. GPS jammer can sometimes help people, but sometimes GPS is not good. For example, it is used for tracking.
Nowadays the society develops faster and faster, the most obvious is the progress of science and technology. It is inevitable that the 4G era will replace the 3G and 2G of the past. Now, before 4G is hot, 5G is coming. For now, however, 4G signals are the mainstream. So, can 4G signal be blocked in the test room? This is a crucial question. In fact, the new test signal shielding device on the market has been upgraded, and shielding 4G signal is almost standard. But, on the market at present some relatively cheap examination room signal shielding device can only block 2G or 3G signals.
With 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 makes life convenient but also exposes the location. In order to be safe, GPS signal shielding device can be used to avoid people from obtaining the location.
People who know the industry can easily get screwed. At least eight antennas will be used to block 4G signals. There are currently two types of eight-wire shields, one for external antennas and one for internal antennas. The two are easy to distinguish, the one with the antenna is similar to the router, but it has more antennas than the router. The built-in one is about the size of a set-top box. Just plug it in and use it. Most eight-wire shields can block many types of signals. Some can even block 5G signals. The 4G era will eventually come to an end, but we’re always on the cutting edge of technology. In order to help customers solve their problems, we have built a space for 5G signal shielding in the new signal shielding device in advance. That way, even if the 4G era ends, there will be no need to replace the hardware.
