In this demonstration we will showcase the real-time fronthaul networking protocol provided with OpenAirInterface (OAI) software packages as well as it's use for experimental deployment of ultra-dense networks. We will provide a real-time demonstration using 4 time-division duplex (TDD) remote-radio units (RRU) connected to a centralized processing server unit using commodity 1Gb-Ethernet-based networking and x86-based signal processing both in the RRU and central unit. The demonstration will also highlight some of the technologies used for over-the-air synchronization and centralized signal-processing for ultra-dense deployments.
