The PL-80M mobile signal jammer can block 2G/3G/4G/WIFI, Bluetooth and other signals within a radius of 1-30 meters (approximately 10-200 square meters), making it impossible for the phone to make and receive calls, send or receive text messages, but it will not interfere with the operation of other electronic devices, thus ensuring the quietness and confidentiality of the installation site. When the phone leaves the partition range, it can resume normal use without any damage to the human body. Widely used in school exam rooms to prevent cheating, student dormitory schedule management, conference room discipline in government agencies, confidentiality, maintaining quietness and solemnity in religious places, and improving production efficiency and reducing work-related injuries in factory workshops.
