Currently, there are two forms of interference with mobile phone data signals:
1. One way is the same as the principle of Internet TV. Put your mobile phone into the packaging bag of the wire mesh product, and usually every electromagnetic wave will be shielded.
2. Another reason is that when we enter a range, there is no signal on the mobile phone.
In fact, wireless signal blocker manufacturers tell you how the shielding works - the wireless signal jammer area has the same electromagnetic wave emitting system as an automatic cell phone. The signal it emits can damage the signal in your phone. Currently, wireless signal jammer devices on the market work according to the second method. In fact, the basic principle is so simple, but it is illegal to use this frequency band without permission and it is not easy to cause economic benefits, but now schools have gradually used it to prevent it.
How wireless signal jammers work: What is the specific principle that harms the decline of mobile phone data signals? When a mobile phone is working, the mobile phone and the base station should be connected within a certain frequency range according to radio waves, and the transmission of information and sound effects should be completed through a certain baud rate and modulation. According to this communication principle, under the premise of working, the data wireless signal jammer in the mobile phone should output power at a certain speed to derive the high-end scanner of the channel. The scanning speed will damage the mobile phone's reception of protocol type data signals.
The mobile phone cannot detect the traditional data information transmitted by the base station, making it impossible for the mobile phone to establish a connection with the base station. Specific manifestations of mobile phone include website search, poor signal, no service system, etc.
Within a certain frequency range, the mobile phone and the base station are connected according to radio waves, and complete the efficient transmission of information and sound through a certain baud rate and modulation. During operation, the signal blocker for sale should scan from low power to high power of the trend wireless channel. The scanning speed will damage the error code in the data signal of the mobile phone receiving protocol type. The mobile phone cannot detect the traditional data information transmitted by the base station, making it impossible for the mobile phone to establish contact with the base station to ensure the purpose of shielding the mobile phone data signal.
