Problems solved by technology

[0007] When operators set up indoor base stations, they need to consider and design complex wiring, such as the power supply lines of small base stations and the lines of the service bearer network; in order to lay out these lines, it is necessary to drill holes through the walls of the original buildings, not only the engineering quantity It is huge and destroys the original interior decoration and appearance of the building, resulting in high installation and layout costs
[0008] In addition, except for pico base stations for home use, most indoor base stations are centralized, requiring a lot of engineering work and professional equipment, often requiring a computer room or rack for installation, and have high professional requirements for builders and subsequent system maintenance personnel

Abstract

The invention discloses communication systems for realizing indoor wireless signal coverage and an air conditioning system. A communication system comprises an ODU and an IDU which are respectively set in an outdoor machine and an indoor machine of the air conditioning system. The ODU carries out corresponding processing on a downlink signal received from a core network or an outdoor base stationaccording to a current set working mode, then sends the processed signal to the IDU, converts the signal sent by the IDU into an uplink signal and then sends the converted signal to the core network or the outdoor base station. The IDU carries out baseband signal processing on the signal sent by the ODU, converts the signal into a radio frequency signal, then sends the signal wirelessly indoors, converts a received indoor radio frequency signal into a baseband signal, carries out baseband signal processing on the signal and then sends the processed signal to the ODU. A signal transmission linebetween the ODU and the IDU is laid out through utilization of a wiring pipeline between the indoor machine and the outdoor machine. Through application of the communication system and the air conditioning system, the indoor wireless signal coverage can be realized, when the communication system is mounted, complex wiring can be avoided, and original decoration and appearance in a building are not damaged.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a communication system and an air-conditioning system for realizing indoor wireless signal coverage. Background technique [0002] The indoor coverage of mobile communication wireless signals has always been a challenging technical problem due to its natural characteristics. From 2G to the current 4G system, providing reliable indoor signal coverage has always been a pain point that mobile operators need to solve. Office and home buildings in modern cities are getting taller and denser, and the radio signals that reach the room are attenuated sharply after encountering metal or concrete walls, making it difficult to communicate normally. For a high-rise building, the signal received in the lower space is usually weak, and there are some signal blind spots; while in its high-rise, there may be no signal coverage at all. The use of mobile terminals in this environment direct...
