Abstract

With the development of economy, the improvement of people's living standard has been increasing and the
construction of buildings is becoming more demanding. These buildings are large in scale and of good quality and
have a strong shielding effect on mobile phone signals. In the middle of the large-scale buildings, underground
shopping malls, underground parking and other environments, the mobile communication signal is weak hence the
phone cannot be used normally and forming a mobile communication blind area and shadow area. In the middle
fl oor, due to the surrounding diff erent base station signal overlap, the ping-pong eff ect, frequent switching of mobile
phones and even dropped calls are seriously aff ecting the normal use of mobile phones. In the building's higher fl oors,
due to the height of the base station antenna, it has abnormal coverage and there is also mobile communication blind
spot. In addition, in some buildings, although the phone can answer normal call but the user density, base station
channel congestion and mobile phone line is diffi cult. In particular, the network coverage, capacity and quality of
mobile communication are the key factors for operators to gain competitive advantage. Network coverage, network
capacity and network quality fundamentally refl ects the mobile network service level and is the theme of all mobile
network optimization work. The indoor coverage system is produced under this background. According to the relevant
statistics in some areas of indoor traffi c in the total traffi c accounted for a higher proportion. Therefore, strengthening
the indoor coverage is of great signifi cance to improve the quality of mobile communication.
