The mobile jammer of this high-end mobile phone is a special signal interference such as school identification. Taking into account the specific use of special schools, the mobile cell phone jammer has the following functions and is specially designed for the customized development of school products. The built-in antenna design eliminates the possibility of damaging the student antenna and avoids the trouble of the spiral antenna. The 8-channel shielding design is more accurate in the anti-interference ability: high-end mobile phone signal interference 6 and 8-channel design, radio jammer obstacle jitter, sometimes The obstacle method of SMS message that is completely shielded without any phenomenon, even when solving the obstacle of 3G mobile phone, the transmission distance with the base station equipment is relatively short. Used to send signals. Due to the multi-channel design, it will inevitably increase the cost of the product. The mobile phone jammers ordinary mobile phone signal jamming equipment may be inconsistent with this product, mainly for some high-end users, and its shielding effect is for all domestic 3G and 4G frequency bands. In the past two years, China Unicom, China Unicom, China Telecom, the only downlink interference signal will never be the electromagnetic environment pollution green mobile operator uplink signal, super mobile phone jammer mobile phone signal including the use of impact sub-shielding method.
