Abstract: A platform hosting a smart distributed antenna system (sDAS) includes a multi-radio access technology (multi-RAT) digital unit (DU) (mDU). The mDU includes a radio management unit (RMU) configured as a software multiplexer enabling broadcast of multiple technologies from a single radio and a single mDU, a field programmable gate array (FPGA) coupled to the RMU and receiving signals digitized in the mDU from analog signals from a wireless carrier, and the FPGA maps received and digitized signals to frequency bands. An optical fiber interface is coupled to the FPGA to provide signals to more remote radio units over a single optical fiber cable. The radio units are coupled to the mDU through only a single optical fiber interface using a daisy-chain configuration. Each radio unit de-maps received digital signals to a specified frequency, converts de-mapped digital signals to RF signals, and provides the signals to a distributed antenna for broadcast.
