O-RAN compliant Distributed Unit High with RLC and MAC Layer 2 processing
High-performance Layer 2 processing for distributed RAN architecture
coRAN L2 (DU High) delivers a fully O-RAN compliant Distributed Unit High implementation supporting Layer 2 radio protocols including RLC (Radio Link Control) and MAC (Medium Access Control). Our solution enables disaggregated RAN architectures with flexible deployment closer to the radio for reduced latency and improved performance.
Designed for high-throughput and low-latency operations, coRAN L2 supports advanced scheduling algorithms, HARQ processing, and seamless integration with both proprietary and open DU-Low implementations via the O-RAN F1 interface.
