Description

Technical Field

[0002] With the continuous acceleration of urbanization, more and more high-rise buildings have sprung up like mushrooms after rain. These skyscrapers have not only become an important part of the city skyline, but also greatly alleviated the pressure on urban living and office space. However, with the increase in building height and the complexity of internal structure, the problem of communication quality inside the building has gradually become prominent and has become an important issue that needs to be solved urgently. Traditional building communication systems often do not fully foresee the special requirements of modern high-rise buildings for communication signals at the beginning of design. Therefore, in practical applications, these systems often cause unstable communication signals when transmitting inside the building due to various factors such as signal attenuation, multipath interference, and the shielding effect of building materials on signals. This instability is not only reflected in the decrease in clarity of voice calls and frequent disconnections, but may also lead to a decrease in data transmission rate, affecting the user experience of modern communication methods such as video conferencing and online office.
