- RAN Flexibility & Scalability: Moving towards more flexible and disaggregated RAN architectures (Distributed Units - DU, Centralized Units - CU) requiring optimized integration.
- Stringent Transport Requirements: Demands for significantly higher bandwidth, lower latency, and precise synchronization across fronthaul, midhaul, and backhaul segments.
- Operational Efficiency: Managing increasingly complex networks while controlling CapEx and OpEx.
- Diverse Service Support: Supporting varied performance requirements for eMBB, URLLC, and mMTC use cases simultaneously.
