Abstract: One exemplary aspect generally relates to public safety communication systems employing Distributed Antenna Systems (DAS) and/or a Digital Distribution System (DDS) as part of a distributed wireless network. More specifically, one aspect relates to a DAS/DDS architecture utilizing a software (re)configurable network. Even more specifically, one aspect relates to a DAS/DDS architecture having a redundant system topology as well as failover capabilities at one or more of the hardware/software level and/or the communication link level.

Abstract: A redundancy system for data transport in a Distributed Antenna System (DAS) includes a plurality of Digital Access Units (DAUs). Each of the plurality of DAUs is fed by a plurality of data streams and is operable to transport digital signals between others of the plurality of DAUs. The redundancy system also includes a plurality of Digital Distribution Units (DDUs). Each of the plurality of DDUs is in communication with each of the plurality of DAUs using cross connection communication paths. The redundancy system further includes a plurality of Digital Remote Units (DRUs). Each of the plurality of DRUs is in communication with each of the plurality of DDUs using cross connection communications paths.
