Why is the mobile phone signal in the villa area so poor and cannot receive the signal?
The villa mobile phone signal enhancement helps you solve the problem of poor signal.
The editor summarizes the following three reasons for the poor mobile phone signal in villas:
1. The signal of the villa itself is poor, far away from the signal tower, and the mobile phone cannot receive the signal in the weak signal area.
2. The thick wall structure of the villa area causes signal blockage.
3. Bad signal due to interference.
Since the mobile phone receives signals to work through the propagation of electromagnetic waves, the base station establishes a connection between the transmitted radio waves and the mobile phone, so as to achieve the purpose of voice call. Therefore, the interference of electromagnetic waves can have a negative effect on mobile phones.
It is normal for the mobile phone to display a 4G signal and change to a 3G or 2G signal when making a call! It is not caused by a malfunction of the mobile phone or a malfunction of the base station. Here's an explanation of why this happens:
1. 4G has only one data channel (commonly known as Internet channel), while 2G and 3G have two channels, data channel and voice channel. So both 2G and 3G can access the Internet and make calls, while 4G can only access the Internet because it only has a data channel.
2. In the early days of 4G, in order to meet the needs of mobile phones when they can make calls when using 4G networks, a solution called CSFB (circuit domain fall) has been developed, which is that when the mobile phone uses the 4G network to make calls or receive calls, the network will automatically fall back from the 4G network to the 2G or 3G network and then start to make and receive calls. However, this technology has a disadvantage, that is, it cannot be connected to the Internet when making calls, so it is inconvenient for some users with more business.
3. Now that 4G technology has matured, in order to meet the better experience of mobile phone users, VoLTE (high-definition voice call) technology has been developed to use 4G network to make calls and access the Internet at the same time. Mobile phones use the data channel of the 4G network to make calls and surf the Internet, and the call quality is clearer than that of 2G and 3G calls.
4. Disconnection due to cross-zone handover failure. Network operators serve users by transmitting wireless signals from base stations, and the range of base stations is limited, so there may be many base stations in an area. All the base stations are combined into a network system, each base station has its own range, beyond this range, the mobile phone has to replace the base station, so as to keep the mobile phone always in the network.
If you want a good signal, you can choose to use a mobile phone on high ground, but it is not convenient. At present, the hot-selling villa mobile phone signal enhancement of Shenzhen ATNJ Communication Technology Co.,LTD. is very suitable for users in some residential areas, basements, villas, urban villages, elevators, sewage plants, etc. Villa cell phone boost can amplify the cell phone signal in our room, thus improving the quality of the network.
