Today's economy is developing faster and faster, and the most significant one is the development of high-tech. It is inevitable that the 4G era will replace the previous 3G and 2G. Nowadays, 4G has not yet covered the heat, and 5G has emerged again. However, at present, 4G signal may be the main one. Therefore, can the 4G signal be blocked by blocking the examination room signal?
This is a very important problem. In fact, the latest examination room signal jammers on the market at this stage have been upgraded to block 4G signals, which is basically standard configuration. However, some of the more cost-effective examination room signal jammers currently on the market can only block 2G or 3G signals.
Can the signal jammer in the examination room block 4G signals?
People who don’t understand this area can be easily fooled. The examination room signal jammer that blocks 4G signals must have at least eight wireless antennas. At present, eight-wire jammers are divided into two types, one with a DVD drive antenna and the other with a built-in antenna. It’s not easy to distinguish between the two types. The one with wireless antennas is similar to a wireless router, but it has more wireless antennas than a wireless router. For the built-in one, it is as big as a 4k set-top box. Plug it in immediately and it's ready to use. Most eight-wire jammers can block various types of signals. Some can even block 5G signals.
The 4G era will one day come to an end, but we have always been at the forefront of high technology. In order to help many users solve their problems, we have built in the latest signal jammer in advance to block the space of 5G signals. In this way, even if the 4G era is over, there is no need to replace the hardware again. Therefore, according to this method, customers can greatly save costs.
