Wireless broadband access system and method

Abstract

The invention discloses a wireless broadband access system and a method, wherein the system comprises a building management unit, a BPL signal coupling unit and a user unit, wherein the building management unit comprises an Ethernet interface and at least one head end module, the Ethernet interface is used for providing an interface for receiving Ethernet signals to the outside; the at least one head end module is used for modulating and demodulating the received Ethernet signals into BPL signals and sending the BPL signals, and / or modulating and demodulating the BPL signals sent from the BPL signal coupling unit into Ethernet signals and sending the Ethernet signals; the BPL signal coupling unit is used for converting and sending the BPL signals sent from the building management unit and / or the user unit to realize the transmission of the BPL signals among coaxial cables and power lines; and the user unit is used for modulating and demodulating the BPL signals sent from the BPL signal coupling unit to realize the access of terminal equipment, and / or modulating and demodulating the received Ethernet signals into the BPL signals and sending the BPL signals.

Description

technical field [0001] The present invention relates to the communication field, and in particular, to a wireless broadband access system and method. Background technique [0002] At present, in order to overcome the problem of not being able to fully cover every corner of the indoor building caused by the difference in the distribution of indoor buildings, the indoor coverage of the wireless broadband system generally requires the use of low-power base stations and multi-point layouts. The transmission problem becomes a key issue. [0003] Building an indoor coverage system may face various environmental differences. For example, some buildings may only have power lines distributed, some buildings may have twisted pair cables distributed, a few high-rise buildings may be equipped with FTTH, and other buildings may be distributed with coaxial cables. Therefore, the indoor coverage system needs to make full use of existing resources, adapt measures to local conditions, quick...
