OpenAirInterface (OAI) Software Alliance broadly focuses on the evolution of 3GPP Cellular stack (eNB + UE + Core Network) on general purpose processor architectures (Intel/ARM) with the goal of establishing generic interfaces with 3rd party RF platforms like EURECOM Express MIMO, National Instruments/Ettus Research USRP, Nuand BladeRF, SoDeRa Lime SDR platforms. The alliance also ensures that several projects conducted within the framework of the alliance are capable of running on Commercial-Off-The-Shelf (COTS) hardware platforms, for example Intel x86 and ARM. The figure below shows the conceptual architecture of OAI and how it relates to several hardware RF platforms.

The Alliance engages itself in projects that enhances the core software (eNB/UE and Core Network) with the goal of running it across several platforms, while at the same time evolving towards future 3GPP standards.

OpenAirInterface (OAI) System Architecture

Since, the evolution of 5G is still under discussion within academia/industry, we plan to identify different areas in which different members of the alliance create projects. The projects are created with the goal of furthering these strategic areas within the alliance and making sure the output of the project is merged back with the main repository at some point. The strategic areas of the alliance ratified by the board are listed here.

  1. 5G Modem
  2. Software-defined 5G system
  3. Heterogeneous 5G Network
  4. Large-scale Emulation
  5. Internet of Things (IoT)
  6. Test and Measurement
