As the name suggests, the cell phone storage cabinet is only used for storing cell phones and does not protect the mobile terminal from communicating with the outside world. The cell phone jammer mainly protects the communication connection signal. Considering the storage situation of the mobile phone, it can effectively protect the mobile terminal and the base station (including GPS), Wiif, infrared, Bluetooth, etc.). In some places where the sound insulation is not satisfactory, once the cell phone is located and located or the microphone (camera) function is activated via the remote control, it can be used to steal sound information (picture) nearby, causing information to be leaked.
In daily work, in order to effectively prevent mobile terminal equipment from being brought into secret places, in addition to relying on the conscious handover by mobile terminal users, we may also need to use mobile terminal equipment. surveillance such as "cell phone detection doors" to get moving. It is further monitored if the person entering the secret location is wearing a mobile terminal.
It's just a way to stop cell phones from working. More and more organizations and businesses have adopted another method of blocking mobile phone signals, namely the use of mobile phone signal jammers.
The signal jammers are mainly intended for various examination rooms, schools, gas stations, churches, courts, libraries, conference centers, theaters, hospitals, governments, finance, prisons, military places and other places where the use of cell phones are prohibited. It is understood that cell phone signal blockers in the market can limit cell phone signals within 500 meters of the transmitting station. The armor radius is adjustable, covering an area of more than 30 square meters. The cell phone signal protection device can only protect the cell phone signal and will not affect other electronic equipment. Save energy, the power is 12W-480W. During operation, the protective cover sweeps from the lower end of the front channel to the upper end at a certain speed. The scanning speed will result in GPS scrambling text messages received by the mobile phone, and the mobile phone will not be able to detect the normal data sent by the base station, which will prevent the mobile phone from establishing a connection with the base station. The cell phone seems to be searching for the network, there is no signal, no service system, etc.
