Call Blocking For Att Cell Phones Makes The Phone Without Network
Cell phone jammers emit jamming signals just like the frequencies the cell phone takes over. It just hinders the connection between the mobile phone and the base station, so that the mobile phone is always in the state of no signal search, and will not cause damage to the mobile phone! Call Blocking For Att Cell Phones When turning on the phone, the electromagnetic waves of the mobile phone and the outside world must not be interchanged. So the phone loses the signal and keeps looking for it, which reduces power consumption. The working principle of mobile phone jammer: The mobile phone and the base station are connected by electromagnetic waves, and the Cell Phone Jammer works from the low-end frequency of the channel to the high-end frequency. Scanning, scanning speed creates garbled characters in the message signal that the phone takes over. The mobile phone must not be able to detect stable data received from the base station, so the mobile phone must not be able to establish a connection with the base station. The mobile phone appears to search the network, no signal, no service system, etc.
Recently, the Jingdezhen Mobile Branch complained to the Municipal Radio Administration, saying that there was unknown signal interference near Jidu Town, Leping, and the base station could not communicate normally. According to his preliminary judgment, the interference location area is in the Yang Zian area, with a range of about 3 kilometers. On February 16, the Municipal Radio Administration organized technicians to rush to the interference site as soon as possible to investigate the interference. Due to the large interference range, the technicians used the portable spectrum analyzer PR100 to monitor the village on foot according to the characteristics of the rural interference area. The direction was measured at a higher position near Chuanxian Village, and it was found that the signal had a trend of increasing in the northeast direction. . Tracking on foot in this direction, it turned out that outside the fence of a farmyard, the signal suddenly became larger, and the noise floor of the base station operating frequency band was raised. Apparently, Call Blocking For Att Cell Phones is being transmitted.
