Cell phone signal jammers can only block cell phone signals and have no effect on other electronic devices. The electromagnetic signal emitted by the mobile phone signal jammer is completely within the specified working frequency band, and can only block the communication signal. And such a signal is always in a relatively static state and will not affect any electronic equipment.
During the working process, the cell phone signalblocker scans the low-end frequency of the previous channel to the high-end frequency at a certain speed. This scanning speed will cause garbled interference in the information signal received by the mobile phone, and the mobile phone cannot detect normal data from the base station, resulting in failure to establish a connection with the base station. The phenomenon presented by the mobile phone is a paging network. The mobile phone has no signal and no service system.
Currently, signaling inhibitors are all bands. Can block all 2G3G4G signals, 2.4GWIFI signals and Bluetooth signals The principle is to interfere with mobile phone reception. The frequencies sent by base stations and wireless routers are shielded.
Therefore, other electronic devices other than the above frequencies can work normally.
But if the frequency is too close to the frequency of the mobile phone signal jammer, it will also be interfered, such as about 700M wireless microphone. This is very close to the frequency of CDMA (870-880MHz), so that the wireless microphone cannot work properly at this time.
