Multipoint-to-multipoint intelligent indoor signal coverage system

Abstract

The invention relates to a multipoint-to-multipoint intelligent indoor signal coverage system. the system comprises an AU unit, an iHUB unit and an RU unit; after being accessed into the multi-path signal source, the AU unit is framed as a standard CPRI signal through digital signal packaging to connect with the iHUB unit through an optical fiber so as to realize the multipoint signal source; the iHUB unit is used for converging the AU unit access signal source and the local access signal sources such as local Wi-Fi, RFID, IOT and monitoring to form the signal source pool; the RU unit is used for performing A-D / D-A conversion on the signal sources distributed by the iHUB unit, and cover the signal indoor after the converted signal sources are amplified by the radio frequency. The system disclosed by the invention has the beneficial effects that the multi-signal source access is provided, in particular, the signal source pool is formed through the convergence of accesses of the signal sources at different physical sites; the signal source pool is dispatched and distributed according to respective coverage requirement of each coverage point, thereby realizing the intelligent coverage function of multipoint signal sources to multipoint signals.

Description

technical field [0001] The invention belongs to the field of mobile communication network optimization, and relates to a multipoint-to-multipoint intelligent indoor signal coverage system. Background technique [0002] With the rapid development of the mobile Internet, indoor signal coverage will show the following trends in the future: (1) 2G, 3G and 4G multi-operator, multi-system, multi-standard, multi-band situation will coexist for a long time; (2) Wi-Fi, RFID, IOT, monitoring and other signals will also be gradually integrated into the indoor signal coverage system; (3) For the smooth evolution of subsequent capacity expansion, precise positioning, local monitoring and other functions, more signal sources will be connected to the indoor signal coverage system; The aggregation and access of signal sources, the intelligent scheduling of multiple sources and the reasonable allocation to multi-point coverage networks will greatly optimize the network performance of the ind...

AI Technical Summary

Problems solved by technology

[0003] At present, the traditional indoor distributed antenna system (DAS: Distributed Antenna System) mainly has the following problems: (1) It only realizes point-to-multipoint signal coverage. It is difficult to achieve access to different geographical locations, especially signal source access scenarios; (2) only have operator signal access, without considering the subsequent Wi-Fi, RFID, IOT, monitoring and other signal access; (3) only complete Source point-to-multipoint coverage, no source selection, distribution, and fixed-point coverage functions, and no subsequent intelligent scheduling, precise expansion, and monitoring functions after multi-source access (especially access to sources with different physical addresses)
