This high-end mobile phone jammer is designed with the following features and custom development of the product school, considering the specific use of dedicated signal jammer special schools such as school specific.
The built-in antenna design eliminates the possibility of damage to the student's antenna and also avoids screw antenna troubles. The more accurate range is the anti-interference capability: High-end mobile phone signal interference 6 And -8 channel design is too close to radio jammer shielding jitter, sometimes none phenomenon completely masked SMS message shielding way, relatively from base station equipment transmission even when solving 3G cell phone shielding Close-range base stations secure a shielded room from mobile phones, even if multiple classrooms can be used to send signals. As a result of the multi-channel design, it is bound to make an increase in product cost, but the communication suppression device is a signal blocker of ordinary mobile phone, mainly for some high-end users, it may not match this product. Can, it is a shielding effect that is targeted for all domestic screenings 3G, 4G frequency band, mobile introduction for the past two years, China Unicom, Telecom, the only downlink interference signal is never electromagnetic environment pollution green Mobile operator uplink signals, mobile phone signals, including the use of ultra-strong jammer impact sub-shielding methods.
