Even if there is no mobile phone jammer to shield the data signal, it is very likely that other safer and more environmentally friendly inspection methods will be used. Therefore, it is better to express these ideas more appropriately. Before deciphering the data signal of the mobile phone signal jammer, you need to know its basic principle: Cell Phone Jammer Pcb Layout According to the shielding style, it is divided into omnidirectional and fixed-type. The omnidirectional type is an olive type, and the fixed-type type is an olive type. Sector type, so omnidirectional cell phone signal jammers have a larger shielding range than fixed-type cell phone jammers; cell phone jammer It is to cause certain radio waves to affect the decline of its mobile signal. If the output Power of the jammer exceeds the output Power of the local mobile signal, there will be no signal on the mobile phone. If the output Power of the mobile phone jammer is lower than the local mobile signal output Power . The output Power of the mobile signal will show the data signal on the mobile phone.
Although the mobile phone signal jammer is called a jammer, it does not actually shield the data signal, but looks like a data Cell Phone Jammer Pcb Layout . Generally speaking, the communication between the mobile phone and the smart phone will be based on the communication base station, that is, the mobile phone-the communication base station-the mobile phone. The mobile phone signal jammer will affect the communication between the mobile phone and the communication base station, causing Unable to send normally. However, the communication base station is public on the mobile phone within a certain range, so it often happens that there is no data signal in the examination room and the normal application is not possible. Nowadays, mobile phone signal jammers on the market can be limited to data signals with a half-length of >20 meters beyond the transmission tower 500M meters. The shielding radius is adjustable. It only shields the data signal and does not cause harm to other electronic products. So if you are not in the test room in the near future, the data signal is not very good, don't worry about blaming the mobile phone signal jammer, it may also be your own mobile phone problem.
