ORAN is a concept that promotes the disaggregation of traditional monolithic radio access networks into modular and interoperable components. This allows network operators to mix and match components from different vendors, fostering innovation, flexibility, and cost-effectiveness.
Here are some technical aspects that might be associated with Ericsson ORAN:
- Disaggregation:
- Remote Radio Unit (RRU): In a traditional RAN setup, the RRU is a tightly integrated part of the base station. In an ORAN, the RRU is separated, enabling interoperability with different baseband units.
- Baseband Unit (BBU): The BBU processes the baseband signals and is typically separated from the radio unit in ORAN architecture. This separation allows for better resource allocation and scalability.
- Open Interfaces:
- Open Fronthaul Interface: ORAN promotes the use of open interfaces between the RRU and BBU, allowing for interoperability between equipment from different vendors. This is typically defined by industry standards like ORAN Alliance.
- Standardization:
- ORAN Alliance: The ORAN Alliance is an industry group that focuses on the development of open and intelligent RAN specifications. Ericsson may contribute to and comply with these standards.
- Virtualization:
- Network Function Virtualization (NFV): Ericsson ORAN solutions might incorporate NFV principles, allowing network functions to be implemented as software applications running on standard servers, providing flexibility in network deployment.
- Cloud-Native Architectures:
- Cloud-Native RAN: Ericsson ORAN solutions may leverage cloud-native architectures, enabling operators to deploy and manage network functions more efficiently and scale resources dynamically.
- Management and Orchestration:
- O-RAN Centralized Unit (O-CU) and O-DU (Distributed Unit): These components are part of the ORAN architecture and handle the management and orchestration of the radio access network functions.
