First, it can block not only 5G LTE and 5G Wimax signals, but also CDMA, GSM, DCS, 3G and 4G signals. This is the perfect and powerful shielding device out there. Second, you can choose which bands to block. If you don't want to block one or two bands, you can turn them off and leave the others on. At the same time, Cell Phone Blocker Frequency Range can still interfere with signals in other frequency bands.
With the development of science and technology, 5G Cell Phone Blocker Frequency Range can cover more and more areas in the examination room. One set can cover a large area, which greatly reduces the cost. Judging from the volume of the examination room cell phone jammer , it is not very large and can be conveniently placed anywhere in the examination room. There is no need to open the center, there is no noise, and it will not be issued to candidates due to the use of mobile phone jammers. They have a big impact. Don't worry about its impact on other electronic devices, cell phone jammers mainly block cell phone signals. At the same time, it is used to cut off the communication between the mobile phone and the base station, and will not cause harm to the human body.
