Blocking Your Cell Phone Number Verizon Blocks Specific Areas

Specifically, our communication network consists of a base station. The coverage of these base stations is a circle. Considering the repeated coverage at the edge, the actual coverage of these base stations is one hexagon after another. Therefore, our mobile network is also called a "cellular mobile network" and each of these coverage areas is called a "cell". Each cell will use several channels in its coverage area, one of which is called a broadcast control channel, denoted as BCH, and the other channels are called traffic channels. In the standby state, the mobile phone intermittently starts the receiving circuit to receive the BCH of the cell where it is located. Once there is an incoming or outgoing call from a mobile phone, the first step is to request instructions from the core network through BCH. The core network handles the calling party or the called party. The core network allocates service channels to mobile phones according to the channel conditions in the coverage area, so that the mobile phone jumps from the BCH to the service channel to realize the call. In order to make the phenomenon that there is no network or the mobile phone cannot access the network in a certain area within the coverage of the mobile network signal, it is necessary to start by destroying the BCH in the cell. If the signal of the same frequency as the downlink frequency of the cell BCH is artificially transmitted in this specific area, and the signal field is stronger than BCH, the mobile phone in this area cannot receive the BCH signal, so that the mobile phone in this area cannot access the network. , Blocking Your Cell Phone Number Verizon is made according to this principle.

The cell phone jammer interferes with digital signals in the frequency band by sending high-power triangular waves. If the antenna is placed unreasonably, or the distance is too far, or there are obstacles in the middle, it will affect the interference effect. First test to see if the phone is also getting interference near the antenna. If you can talk normally here, it means that Blocking Your Cell Phone Number Verizon is faulty or the antenna is connected incorrectly. Of course, it may also be set incorrectly.
