O-RAN compliant Layer 3 processing with advanced PDCP, SDAP, and RRC protocols
High-performance Central Unit for 5G/6G RAN architecture
coRAN L3 (CU) delivers a fully O-RAN compliant Central Unit implementation supporting Layer 3 radio protocols including PDCP (Packet Data Convergence Protocol), SDAP (Service Data Adaptation Protocol), and RRC (Radio Resource Control). Our solution enables disaggregated RAN architectures with flexible deployment options for both 5G NR and future 6G networks.
Header compression, integrity protection, and ciphering for user and control plane data
SDAP-based QoS flow management with 5QI mapping and traffic prioritization
Complete RRC state machine, mobility management, and connection establishment
"Built for cloud-native environments, coRAN L3 supports containerized deployments on standard COTS hardware, enabling operators to reduce costs while maintaining high performance and scalability."
