Accelleran dRAX: Your Open RAN, delivered

Accelleran’s dRAX™ delivers proven virtualised software components to enable real-world deployment of multi-vendor, disaggregated Open RAN. Containerised and ready for deployments on 21st Century network infrastructure, dRAX is fully integrated with popular orchestration platforms.

dRAX: Cloud-Native Open RAN software

Accelleran’s dRAX is our cloud-native, O-RAN aligned product, comprising a loosely coupled (CUPS) CU, a distributed near-RealTime/non-RealTime RIC, and a RAN-oriented SMO/Dashboard with xApp/rApp SDK.

dRAX offers an open software framework for 5G RAN control plane functions, closely aligning with Open RAN principles.

Its architecture is rooted in cloud-native principles, utilising containerised microservices that communicate asynchronously.

Each key RAN component, whether it’s CU-CP, CU-UP, nRT-RIC/nonRT-RIC, SMO, or xApp/rApp SDK, is disaggregated into distinct service entities. 

dRAX integrates with several OpenRAN ecosystem DUs/RUs, accommodating both Split 7.2 and Split 2 architectures.

dRAX: e/gNodeB Software

Enabling the full functionality of an e/gNodeB, this software package delivers an integrated software solution, including all the essential components: Layers 1, 2 and 3 of the RAN function and the necessary OAM and security features.

The  optimised multi-platform carrier-grade small cell software has been designed with portability and flexibility at its core. Currently available for operation on Marvell 71xx and 73xx silicon platforms, this software ports across multiple silicon platforms, and supports different Open RAN splits, from a fully embedded traditional Small Cell to virtualised C-RAN architectures.

The xNodeB software enables OEMs, ODMs and system integrators to use their hardware platform of choice.


While open standards are prerequisite to delivering truly interoperable products, integrating the individual components into a working solution remains a task cut out for our experts. Providing test environments and services necessary to integrate a multi-sourced Radio Access Network, dLAB delivers on the Open RAN promise.

With our experience of integrating hardware and software network functions, from Radio Units, over Distributed and Central through the RAN Intelligent Controller, we offer an effective path towards a fully operable and integrated Radio Access Network, both on premise as well as in our own labs.
