VIRTUAL RADIO ACCESS NETWORK USING SOFTWARE-DEFINED NETWORK OF REMOTES AND DIGITAL MULTIPLEXING SWITCHES

A system for routing signals in a Distributed Antenna System (DAS) includes one or more Base Band Units (BBUs). Each of the one or more BBUs has one or more digital outputs. The system also includes aplurality of Digital Multiplexer Units (DMUs) coupled to each other and operable to route signals between the plurality of DMUs. Each of the plurality of DMUs is operable to receive one or more digital inputs from the one or more BBUs. The system further includes a plurality of Digital Remote Units (DRUs) coupled to the plurality of DMUs and operable to transport signals between the plurality ofDRUs and one or more of the plurality of DMUs. 种用于在分布式天线系统(DAS)中路由信号的系统包括个或多个基带单元(BBU)。所述个或多个BBU中的每个都具有个或多个数字输出。该系统还包括多个数字多路复用器单元(DMU)，其彼此耦合并且可操作以在多个DMU之间路由信号。所述多个DMU中的每个都是可操作的，以接收来自个或多个BBU的个或多个数字输入。该系统还包括多个数字远程单元(DRU)，其与所述多个DMU耦合并可操作以在多个DRU和多个DMU中的个或多个DMU之间传送信号。
