OpenRAN software developer Accelleran has contributed to the O-RAN Alliance’s Virtual Showcase with two demonstrations.
The third O-RAN Alliance Global Plugfest has seen OpenRAN interoperability testing in labs across Europe, Asia and North America. This is key to demonstrating the ability of OpenRAN elements to work together, alongside test centres such as SONIC in the UK

The tests of Accelleran’s dRAX 5G Centralized Unit (CU) and near real-time RAN intelligent controller (RIC), were conducted at the i14y Lab in Berlin, which acted as European Open Testing and Integration Centre (OTIC).
The first of the demonstrations focused on benchmarking the dRAX CU component load and scalability. This was undertaken on two separate test beds, based on emulator equipment from Keysight Technologies and TeraVM O-CU Tester from VIAVI Solutions respectively. Using these testbeds, a number of load scenarios covered different User Equipment (UE), radio unit (RU) and distributed unit (DU) configurations. The work confirmed the interoperability of Accelleran CU with different DU/RU/UE arrangements, as well as different prospective workloads, while using non-accelerated standard server hardware.
The second activity looked at the dRAX near real-time RIC, with a specific focus on O-RAN defined E2 interface. The test was conducted with VIAVI TeraVM O-RAN RIC Test, confirming that dRAX RIC E2 interoperability could be fully achieved. It also verified the ability of the accompanying xApps, developed using dRAX RIC SDK, to deal with data coming through this interface.
“These plugfest demonstrations clearly validate Accelleran’s ongoing contribution to the OpenRAN ecosystem and that we can live up to the industry’s expectations. It makes clear that our technology can work seamlessly with other vendors’ components via O-RAN specified interfaces.” states Arnaud Polster, CSO at Accelleran. “The demonstrations underline how we enable MNOs to gain differentiation via our software in the areas of standards-based RAN Intelligence, cloud-native CU scalability and hardware independence.”
