Indoor distribution system with CATV and a variety of wireless communication modes fused and implementation method thereof

Abstract

An indoor distribution system with CATV and a variety of wireless communication modes fused and an implementation method thereof are provided. The indoor distribution system comprises a near-end machine and a remote-end machine. The near-end machine receives CATV signals and multi-source radio frequency signals including TD-LTE MIMO signals, carries out combination, filtering and frequency conversion on the multiple signals and transmits the signals through a CATV line. The remote-end machine receives CATV signals and a variety of wireless communication signals including TD-LTE MIMO signals through the CATV line, separates the signals, carries out filtering, power detection and amplification on each signal, carries out power balance adjustment on the TD-LTE MIMO signals, and uniformly transmits the signals to access nodes. By adopting the method of the invention, coverage of all network signals is enabled to be basically consistent, a wireless signal of each wireless node is covered by an antenna, and the TD-LTE MIMO signals are respectively covered by a plurality of antennas. The CATV signals are output to a set-top box through the remote-end machine, high-quality interference-free wireless network coverage and TV function in the access nodes are finally realized, and the CATV signals are transmitted to a TV through a cable, thus ensuring normal TV program watching.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to an indoor distribution system and its realization method in which CATV and multiple wireless communication systems are integrated. Background technique [0002] For mobile communication networks, especially 4G networks and 3G networks, indoor coverage is a very important component. According to statistics, about 70% of services are performed indoors, and with the gradual increase of data service applications, the proportion of indoor services is still increasing. For Time-Division Long-Term Evolution (TD-LTE) networks, the performance of the indoor distribution system will greatly affect the experience of customers and the revenue of operators. [0003] In the 2G / 3G era, a large number of indoor distributed antenna systems (DAS) have been built, and TD-LTE indoor coverage can be quickly realized based on DAS. At present, "baseband processing unit (BBU) + remote radio unit (RRU)...

AI Technical Summary

Problems solved by technology

However, as mentioned above, the "BBU+RRU+Distributed Antenna System" solution cannot introduce signals into large residential areas, high-rise residences, hotels, large dormitory areas and other building rooms, but can only be laid in public areas such as corridors and corridors

Due to the barrier of the wall inside the room, the coverage effect is not good. However, due to the technical characteristics of TD-LTE, the space and the wall have a greater transmission loss to it. If the signal cannot be introduced into the room, the communication effect will be even worse, which seriously affects the communication quality, reducing user satisfaction
