How To Use Cell Phone Jammer
The principle of the mobile phone signal jammer is: within a certain frequency range, the mobile phone and the signal tower are connected by radio waves, and the data and sound transmission is completed with a certain baud rate and modulation method. In view of the above communication principle, the How To Use Cell Phone Jammer scans from the low-end frequency of the forward channel to the high-end at a certain speed during the working process. This scanning speed can cause garbled influence in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the signal tower. cell phone jammer So that the mobile phone cannot establish a connection with the cell tower. The mobile phone is manifested as a search network, no signal, no service system and other phenomena. Eventually, the mobile phone has no signal and cannot receive text messages or calls.
The effective shielding range of mobile phone jammers will be different in different use scenes. This is closely related to the field strength of the signal on site. The shielding range of mobile phones of different standards in the same site is not necessarily the same; the factors that affect the shielding range include but are not limited to: distance from the base station, orientation, obstacles, the wall material of the site building, How To Use Cell Phone Jammer the installation height , Installation specifications, etc.; each antenna has a frequency band identification, which must correspond to the frequency band identification on the host one-to-one. Before the mobile phone jammer is turned on, it must be ensured that each antenna is connected reliably. It is never allowed to turn on the device without connecting the antenna;
