Although a mobile phone is a wireless communication device, it is used everywhere, but there are invisible wires dragging it, that is, the mobile phone base station. Whether making or receiving a call, the first step is to establish contact with a nearby cell phone base station. If you hold a mobile phone in each of your left and right hands, and use the left-hand mobile phone to dial the right-hand mobile phone, the electromagnetic waves of the mobile phone are not directly from the left-hand to the right-hand, but from the left-hand mobile phone to a distance of several hundred meters. The cell phone base station, and then send back to the right hand cell phone in a large circle (except for the bluetooth function). Under normal circumstances, the base station brother and the mobile phone brother are chatting in full swing. The radio signals sent by the two sides come and go, but when Cell Phone Signal Blocker 70 Feet is turned on, it will "beat gongs and drums" around the phone, and the signal power is much higher than the received base station signal. Double the "noise" radio wave signal, the phone can't hear what the base station is saying, can't receive the base station's signal normally, and the connection between the two is cut off.
The community has been handed over since the beginning of this year, and there are currently 74 households. "In the usual management, we have not received the problem that the residents report that the mobile phone signal is not good." So, are there any other residents who report abnormal signals? Is there any serious disturbance from Cell Phone Signal Blocker 70 Feet in the area? If cell phone jammer does have an impact on communication frequency, will the mobile company take further measures next? , School cell phone jammers have been installed for some time, mainly to prevent school students from playing with their phones at night. "The mobile phone jammer is activated every night from 10:00 pm to 4:00 am the next day, and is currently in normal use." As for the installation of mobile phone jammers, do I need to file with the local radio management department? The school is not responsible for the installation of this equipment, so the specific process is unclear. Reporters are advised to consult the local radio management department.
