MULTIPOINT-TO-MULTIPOINT INTELLIGENT INDOOR SIGNAL COVERAGE SYSTEM

摘要

The present invention relates to a multipoint-to-multipoint intelligent indoor signal coverage system, mainly comprising AU units, an iHUB unit, and remote units (RUs). (1) After each AU unit accesses multiple signal sources, digital signals are packaged and framed to form standard CPRI signals, and are connected to the iHUB unit by means of an optical fiber so as to achieve a multipoint signal source, and in particular, convergence and access of signal sources at different physical site addresses; (2) the iHUB unit converges the AU unit access signal source and local access signal sources such as local Wi-Fi, RFID, IOT and monitoring to form a "signal source pool", schedules and allocates the "signal source pool" according to the difference in signal coverage requirements of each RU, and allocates "required signal sources" to different RUs by means of a transmission medium, so as to achieve accurate coverage of the signal sources of each RU; (3) the RU performs digital-to-analog conversion/analog-digital conversion and radio-frequency amplification on the signal sources allocated by the iHUB unit, and then performs indoor signal coverage. The beneficial effects of the present invention are: the present invention provides multi-signal source access, and in particular, access and convergence of signal sources at different physical sites, so as to form a "signal source pool", and schedules and allocates the "signal source pool" according to the respective coverage requirements of multiple coverage points, thereby achieving the intelligent coverage function of multipoint signal sources to multipoint signals.
