Abstract

The invention discloses a mobile communication indoor coverage system based on novel digitization, which comprises a baseband processing unit, a plurality of concentrators and a plurality of radio remote units, and is characterized in that the baseband processing unit is connected with the concentrators through CPRI interfaces, and the concentrators are connected with the radio remote units through the CPRI interfaces. The connecting medium of the concentrator and the radio remote unit of the system can be selected in various ways, the construction difficulty and deployment cost of the indoordistributed system are reduced, and the support of the indoor distributed system for the high frequency band is realized through different designs of the function positions of the physical layer.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and more specifically, relates to a novel digital-based mobile communication indoor coverage system. Background technique [0002] In traditional mobile communication indoor distributed systems, the RF optical cables and indoor distribution devices do not support the new 5G NR frequency band, and the deployment cost is high and the installation is limited. [0003] It usually takes two to three days to troubleshoot a problem in a traditional indoor distributed system, and requires regular on-site inspections, resulting in high maintenance costs. Contents of the invention [0004] The present invention provides a novel digital-based mobile communication indoor coverage system in order to overcome the defects of limited supported frequency band, high maintenance cost and difficult construction of the mobile communication indoor distributed system in the prior art. [0005] P...
