An outdoor distribution system and its networking method

Abstract

This invention discloses an indoor distribution system and its networking method, in which, the system includes BBU, RHUB providing routes for baseband information and RRU to realize a requirement supporting indoor cover of large volume, which is convenient for expanding volume and reducing operation cost. This invention also provides a networking method.

Description

technical field [0001] The invention relates to base station technology, in particular to an indoor distribution system and a method for forming a network through the system. Background technique [0002] The buildings in modern cities are getting taller, more and more dense, and the radio signals of wireless communication are blocked and attenuated. Most modern buildings use reinforced concrete as the skeleton, plus fully enclosed exterior decoration, Radio signals are severely shielded and attenuated, making normal communication difficult in such buildings. [0003] In addition, in the lower floors of high-rise buildings, base station signals are usually weak, such as underground parking lots, underground shopping malls, subways, tunnels, etc. Therefore, the signals entering the room are usually messy and unstable, especially in the middle and high-rise buildings of some high-rise buildings that are not completely enclosed. , Reflection, diffraction and other means of en...

Problems solved by technology

The performance of passive system equipment is stable and easy to maintain. However, after the signal passes through the power splitter, coupler and line attenuation, the strength of the signal reaching each antenna is different, resulting in uneven coverage. Specifically, the passive system has the following problems :

[0012] In some large buildings, the use of RRU-based ADAS generally requires dozens of low-power RRUs for remote coverage, and when each RRU is an independent cell, supporting dozens of RRUs requires a lot of time Baseband resources are not economical enough for practical application. At present, the maximum number of cells supported by a macro base station is generally 12 to 24, and the coverage scale is relatively small. In addition, the interface between the BBU and the RRU is dedicated and not open, so it cannot provide multiple operations. business sharing
