Indoor coverage device and multi-standard coverage system

Abstract

The invention provides an indoor covering device and a multi-system covering system. The device comprises a baseband expansion module, and a plurality of multi-system distributed modules which are arranged in the covering area; the baseband expansion module in a downlink is used for receiving a downlink baseband signal output by a baseband data processing module of a small base station, performing bit width conversion for the downlink baseband signal and distributing to each multi-system distributed module; the multi-system distributed modules are used for receiving the downlink baseband signal from the baseband expansion module, performing bit width module for the downlink baseband signal, and performing radio frequency processing to obtain a downlink radio frequency signal for achieving signal covering. According to the device, the baseband expansion module is used for performing bit width conversion for the downlink baseband signal and distributing the downlink baseband signal to each multi-system distributed module in the covering area, then the multi-system distributed module is used for converting the downlink baseband signal into the radio frequency signal for achieving network covering, and therefore, the network coverage range can be expanded, and medium and large size scenes can be covered with the signal well.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an indoor covering device and a multi-standard covering system. Background technique [0002] Nowadays, urban buildings are getting taller and denser, and the radio signals of wireless communication are blocked and attenuated. It is difficult to carry out normal communication in such buildings. In the lower floors of high-rise buildings, base station signals are usually weak, such as underground parking lots, underground shopping malls, etc. are usually blind spots; in the central areas of large and medium-sized cities, base stations are usually dense, such as the average station distance is less than one kilometer, so the signals entering the room are usually It is relatively messy and unstable, especially in some high-rise buildings that are not completely enclosed. The strong and sometimes weak is unstable, and the interference from adjacent cells is serious. W...

Problems solved by technology

[0005] Based on this, it is necessary to provide an indoor coverage device and a multi-standard coverage system for the problems that the existing small base stations have a small coverage area and the signal coverage of medium and large scenes is poor.
