Can the signal blocker in the examination room block the 4G signal of the mobile phone?
Today's society is developing faster and faster, the most obvious is the progress of science and technology. It is inevitable that the 4G era will replace the past 3G and 2G. Now 4G is not hot, and 5G is emerging again. However, 4G signals still exist as the mainstream. So, can the signal shielding of the exam room shield the 4G signal? This is a very critical question. In fact, the new test room signal jammer on the market have been upgraded, and blocking 4G signals is almost standard. However, some of the cheaper test room signal blockers on the market can only block 2G or 3G signals.
People who don't know this industry are likely to be fooled very easily. The test room signal blocker that shields 4G signals must have at least eight antennas. At present, eight-wire shields are divided into two types, one is an external antenna, and the other is an internal antenna. The two are well differentiated. The one with antennas is similar to the router, but it has more antennas than the router. As for the built-in, it is the size of a set-top box. Just plug it in directly. Most 8-wire shields can shield many types of signals. Some can even block 5G signals. The 4G era will come to an end one day, but we have always been at the forefront of technology. In order to help our customers solve their problems, we built a space to block 5G signals in the new signal blocker in advance. In this way, even if the 4G era is over, there is no need to replace the hardware facilities. Therefore, in this way, the cost can be greatly saved for the customer.
