People often complain about poor mobile phone signals and unstable indoor mobile phone signals. The signal problem is really annoying, but the reasons for the poor mobile phone signal are different in different situations. To improve it, we must first understand the reasons. If the signal amplifier is not installed in time, the mobile phone in the blind area of the signal coverage will cause the call to be interrupted or not in the service area. The reason for this phenomenon is that the network coverage of the base station in the blind area is insufficient, such as suburbs, rural areas and other places with low base station density. There is a reason and in the city, the signal is blocked by reinforced concrete. Such as in KTV private rooms, elevators, underground parking lots, etc. This situation can be improved very well through beecom Small Radius Cell Phone Blocker . Because the handover is unsuccessful, the mobile phone will also be dropped. cell phone jammer Mobile operators serve users by sending electromagnetic wave communications through base stations and mobile phones. Then, the base stations are generally cellular, with limited coverage, and there may be several different base stations in a large area at the same time. When the mobile phone terminal moves away from the coverage of the current base station, it needs to switch the base station, so as to ensure that the mobile phone can always receive the wireless signal of the network.
When a user passes from a cell covered by one base station to a cell covered by another base station during a call, the voice channel used by the user for communication should also be switched at the same time. However, once the base station service of the new cell is busy or has a temporary failure, so that there is no extra channel allocated to the new user, the handover of the base station will fail, and the call of the user will also be interrupted. In this case, only operators can increase base stations to improve, and users themselves cannot improve. Sometimes the signal is actually good, but the interference is too large to communicate. The principle of mobile phone communication is that the base station establishes a connection between the base station and the mobile phone by transmitting radio waves, so as to realize the call or data transmission. Therefore, once the electromagnetic wave encounters interference, it will have an impact on the mobile phone. Especially when the interference of some electromagnetic waves in the air exceeds a certain level, and the signal-to-noise ratio of the signal source is reduced below a certain range and cannot be recognized by the mobile phone, there will be no signal or frequent disconnection of the mobile phone. Check the surrounding signal sources and interference sources. In addition, sometimes due to some temporary network failures, or the network is very busy, such as when there are many people in the CBD, and Small Radius Cell Phone Blocker is installed, or when the call volume is extremely concentrated, the mobile phone will also be unable to communicate.
