8341-D8 enhanced signal blocker, unique custom high-gain antenna, efficient management chip shielding only shields effective signal reception, the coverage range of the high gain antenna can reach 10-30 meters (depending on the signal strength of the base station) shielding range shielding operators dual-mode 2G, 3G, 4G, GPS, WIFI and other signals. Completely disconnect all communications within the shielding range from the outside world; The communication network appears as no network or no signal, no service. With the development of science and technology, mobile phone information leakage, telephone detonating bombs, serious areas, etc., have caused social harm; Due to the increasing coverage of the current signal, the shielding effect of the shielding device is poor.
