This kind of interference device exists. Previously, due to technical limitations, the 4G and WIFI signals could not be interfered at the same time. But now, as technology advances, the problem has been solved. Of course, with 5G coming, this problem could come back. After all, 4G jammers can't shield 5G
At present, France, Japan, China and other countries have used this cell phone jammer on a large scale. Used in education to prevent students from cheating and using mobile phones during class. In addition, some business owners also purchase such equipment for meeting rooms and office areas. In addition, many libraries, movie theaters and concert halls are now using these devices.
