vRAN virtualizes radio access network functions on standard hardware, enabling flexible, software-defined wireless infrastructure for future networks.
Network Architecture
What is vRAN?
Virtualized Radio Access Network (vRAN) separates radio network software from proprietary hardware, running baseband processing functions on standard commercial servers. This architecture replaces traditional monolithic base stations with disaggregated, cloud-native components that can be deployed flexibly across edge and centralized locations.
How It Works
vRAN splits the radio access network into three main components: the radio unit (RU) at cell sites, distributed units (DU) for real-time processing, and centralized units (CU) for higher-layer functions. These elements communicate via open interfaces, allowing software functions to run on commodity x86 servers or specialized accelerators. The virtualized baseband processing can be dynamically allocated and scaled based on network demand, enabling operators to optimize resources across multiple cell sites from centralized pools.
Role in 6G/7G Networks
For 6G and 7G networks, vRAN provides the foundational flexibility needed to support diverse use cases from ultra-low latency applications to massive IoT deployments. The architecture enables AI-native network operations, allowing machine learning algorithms to optimize radio resources in real-time across virtualized infrastructure. vRAN's cloud-native design supports the network slicing and edge computing capabilities essential for 6G's vision of ubiquitous intelligence and seamless human-machine integration.
Current State
Major operators worldwide are actively deploying vRAN solutions, with companies like Dish Network building entirely cloud-native 5G networks using vRAN architecture. The technology has matured significantly, with established vendors and new entrants offering commercial vRAN platforms that meet carrier-grade performance requirements for current 5G networks.
