The focus of the ORCA project was to set up open experimentation facilities to promote wireless innovation in market segments which require low-latency communication and real-time interactions, including manufacturing, automotive industry, healthcare, ambient assisted living, public events, home automation, and utilities. End-to-end networking experimentation was realized going from Software-Defined Radio (SDR), with Software-Defined Networking (SDN) to Dynamic Spectrum Sharing (DSS). One of the outcomes was an open source full-stack real-time SDR Wi-Fi on FPGA with embedded ARM and Linux, eventually becoming openwifi.
