How does a mobile phone signal blocker work? Why can it block signals?
During the operation of the mobile phone station, all operations in the mobile phone will be converted into data signals, and then the data will be transmitted to the base station using electromagnetic waves. The electromagnetic wave band links the mobile phone and the base station at a certain speed, and uses a specific link port and modulation method to complete the conversion and transmission of the database, while the signal base station and the signal base station implement the network solution based on the optical fiber circuit or microwave circuit.
The coverage area of the signal base station is very limited. If you happen to be at the edge of the coverage area, there will be a phenomenon of signal weakening. Mobile phone signal blockers generally block the electromagnetic waves emitted by the mobile phone and the signal base station connection. The communication between the mobile phone and the signal base station is interrupted.
Random event electrostatic induction or noise The transmission of random events within the frequency range of electrostatic induction or noise makes it impossible for machines close to the mobile phone signal blocker to connect to the signal base station. For example, if the sports car engine module is started, you will pass the phone. The local noise itself is very strong, which makes the mechanical equipment unable to connect normally, effectively blocking the normal operation of the mobile phone signal.
The cell phone blocker will also send out interference signals. The carrier communication frequency of this signal is the same as the carrier communication frequency of the communication base station signal. Therefore, it can cause error code effect when the mobile phone receives the signal. The mobile phone cannot detect which are the normal data information transmitted by the communication base station and which are the interference signals, effectively blocking the normal operation of the mobile phone signal.
