Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a base station and an air conditioning system for implementing indoor wireless signal coverage.
Background
Indoor coverage of mobile communication wireless signals is a challenging technical problem due to its natural characteristics, and providing reliable indoor signal coverage is always a pain point to be solved by mobile operators from 2G to current 4G systems. Buildings in offices and homes in modern cities are higher and denser, and radio signals arriving indoors are attenuated sharply after encountering metal or cement walls, so that normal communication is difficult. For a high-rise building, the signal received by the low-rise space is generally weak, and partial signal blind areas exist; at its high level, there may be no signal coverage at all. When the mobile phone terminal is used in such an environment, poor voice quality, serious call drop phenomenon and frustrating data communication are directly caused to the customer experience. In addition, the indoor signal quality is also related to the capacity of the base station, and in some indoor buildings with very high temporary population density, such as stadiums and large conference places, the problems of traffic jam, no access and the like can be caused only by depending on the service coverage of the outdoor base station.
In the upcoming 5G era, the international standards organization defined two large frequency bands as the frequency spectrum used by 5G. The frequency band below 6GHz is higher than that of the existing mobile system, and the frequency band of millimeter waves is as high as 24.25-52.6 GHz, so that the penetration capability of wireless signals on barriers such as building outer walls, inner walls and the like is weakened. In addition, the larger bandwidth required for high-speed data transmission of 5G directly results in a reduction in the effective transmission distance of wireless signals. It is expected that the problem of indoor signal coverage will be more serious in the 5G mobile system.
From the mobile service perspective, most wireless services are generated indoors, and 80% of wireless communication services (including WiFi and mobile networks) are completed indoors in 2016 according to the ABI Research statistics of an authoritative global consulting agency. Therefore, improving indoor signal coverage, providing reliable communication quality and sufficient communication capacity is a service pain that mobile operators are trying to solve, and is an important content of engineering construction and network optimization work.
To solve the above indoor coverage problem, the current method is to deploy an indoor base station. And transmitting signals through the small base station in each indoor area to form indoor small base station coverage, and extending the service bearing network to the indoor. By the extension of the macro base station network, the purposes of eliminating an indoor coverage blind area and providing stable and reliable signal coverage and system capacity for indoor mobile communication users are achieved, so that the users can enjoy high-quality personal communication services indoors. The bearer network extending indoors may be based on wired or wireless technology.
Indoor small base stations can be divided into a micro base station (Picocell) and a pico base station (Femtocell), namely a home base station, according to the sizes of the transmitting power and the capacity of the indoor small base stations; the system can be further divided into an independent small base station (standard) or a Centralized small base station (Centralized) system according to the network deployment mode of the small base stations. However, when deploying a small base station indoors today, the following challenges and problems are prevalent:
when an operator sets up an indoor base station, complex wiring needs to be considered and designed, such as a power supply line of a small base station and a line of a service carrying network; in order to lay the lines, the original building needs to be perforated through the wall, so that the engineering quantity is huge, the original decoration and appearance of the building are damaged, and the installation and laying cost is high.
