Problem addressed

Limited choice of network equipment, high CAPEX and low deployment flexibility of equipment. Network resources not efficiently utilised, affecting user experience.

Innovation
  • O-DU fronthaul interface (between O-DU and O-RU) in 5G O-RAN standard.
  • O-CU and O-DU F1 interface in 5G O-RAN standard. O-RAN F1 interface provides means for interconnecting O-CU and one or more O-DUs.
  • E2 interface (between RIC and O-DU/O-CU) in 5G O-RAN standard enables AI/Machine Learning (ML) to cover non-real-time RIC.
  • 5G FAPI interface between L2/L3 software and L1.
Key impact
  • MNOs can use equipment from multiple vendors and still ensure interoperability.
  • The open environment is widening the ecosystem, expanding the number of vendors, innovations and options available.
  • AI can be introduced to optimise the network for different use cases.
  • New features can be added quickly for end users.
Award
