The built-in antenna design eliminates the possibility of student antenna damage and the trouble of screw antenna. The more accurate range of 8-channel shielding design is the anti-interference ability: high-end mobile phone signal interference 6 and -8 channel design, Cell Phone Blocker Movie Theater shielding jitter, sometimes completely shielding SMS shielding method has no phenomenon, even if the 3G mobile phone shielding is solved, the base station is far from the base station equipment transmission. relatively close. Multiple base stations protect your phone from a shielded room, even if you can use it to send a signal. Due to the multi-channel design, the product cost is bound to increase. Communication suppressor common cell phone jammer may not match this product.
The key of the mobile phone signal jammer is suitable for various examination rooms, universities, gas stations, main churches, courts, public libraries, international conference centers (rooms), cinemas, hospital clinics, government departments, financial industries, prison cells, public security organs, Places where the use of mobile phones is strictly prohibited in areas such as the National Defense Center. According to statistics, the Cell Phone Blocker Movie Theater on the market today can limit the data signal of 500M meters and 20 meters away from the transmission tower by half. Shielding semi-warping adjustable type, only shielding data signal, will not cause damage to other electronic products. It is mainly aimed at some high-end users. Introduction, Unicom and Telecom, the only downlink interference signal is always the uplink signal of the green mobile operator that pollutes the electromagnetic environment, super blocking the mobile phone and affecting the mobile phone signal, including the use of sub-shielding.
