The principle of 4G5G mobile phone signal amplifier

　　The basic principle of a 4G5G mobile signal amplifier, also known as a signal booster or repeater, is to receive and amplify weak signals emitted by the operator's base station, and then retransmit them to enhance the signal strength received by the mobile phone. This type of equipment usually consists of three parts: outdoor antenna, amplifier host, and indoor antenna, forming a complete signal transmission link

　　1. Enhance signal strength: By amplifying the signal, a mobile signal amplifier can significantly improve the signal quality received by the phone, making calls clearer and network usage smoother;

　　2. Expanding coverage: In areas with weak signals, mobile signal amplifiers can expand the coverage of operator base stations, allowing more users to enjoy stable communication services;

　　3. Strong compatibility: 4G and 5G mobile signal amplifiers typically support multiple frequency bands and operator networks, with good compatibility to meet the needs of different users;

　　4. Easy installation: The device is compact in size, and the installation process is relatively simple. Users can complete the installation and debugging themselves.
