Sometimes the signal is necessary, but sometimes it is not necessary. Sometimes GPS can help people, and sometimes GPS is not good. For example, it is used for tracking, so Best Portable Cell Phone Signal Blocker also comes in handy. 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 cell phone jammer on the market has been upgraded, and shielding 4G signals is almost standard. However, some of the cheaper mobile phone jammers on the market can only block 2G or 3G signals. In 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. For safety, mobile phone signal jammers can be used. This way you can prevent someone from getting the location.
People who don't know this industry are likely to be fooled very easily. The exam room Best Portable Cell Phone Signal Blocker that shields 4G signals must have at least eight antennas. At present, the eight-wire mobile phone signal jammers 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 cell phone jammers can block 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 the problem, we built a space to block 5G signals in the new mobile phone signal jammer in advance. In this way, even if the 4G era is over, there is no need to replace the hardware facilities. If the signal of the mobile phone is blocked, the general location will not be sent out, so blocking the signal of the mobile phone is not much different from blocking the GPS.
