With the development of mobile Internet technology, mobile phones have become an important channel and tool for us to contact the outside world and obtain information. The biggest feature of the army is its closed management. Compared with outsiders, soldiers know less about what is happening in society and lack relevant information. This doesn't really matter when you're in service, but when you're discharged from the military, it's huge.
Retired soldiers will feel that they are seriously out of touch with society in society, and it is more difficult to find jobs and interpersonal relationships, and will not be able to reintegrate into society for a long time. In view of the general social phenomenon that mobile phones are becoming more and more close to people's lives and have an increasing impact on people's lives, military personnel can use mobile phones (including smart mobile phones), but this also adds more uncertain risks to the military's security management work. Therefore, installing a full-band signal shielding device can effectively prevent criminals from stealing secrets through mobile phone intrusion.
By installing a full-band signal jammer to shield the mobile phone signal, according to the communication principle of the mobile phone, the corresponding interference equipment can scan from the low-end frequency of the forward channel to the high-end frequency at a certain speed during the working process. This scan can form garbled codes in the signal sent by the base station received by the mobile phone, the mobile phone cannot receive the letter from the base station, the mobile phone cannot search for the network, no signal, no service system, etc.
