Choosing increased complexity in management and troubleshooting efforts reflects a critical reality of virtualized Radio Access Network (RAN) environments. In such setups, various components and services are decoupled and run in a virtualized manner, which can lead to numerous interconnected parts working in tandem. This can complicate the task of monitoring and maintaining the overall system because issues may arise from multiple layers — such as the virtual machines, containers, or network functions — making root cause analysis more time-consuming and challenging.

The integration of different technologies and the use of software-defined networking principles can enhance flexibility and efficiency, but they also introduce new variables and potential points of failure. For example, interdependencies between virtualized functions, changes in network conditions, and the need for orchestration across diverse environments can make troubleshooting more complex. This complexity requires more sophisticated tools and skilled personnel, potentially increasing the burden on operators and technicians.

While reduced data throughput, limited scalability of services, and higher initial costs for deployment can also be concerns in some contexts or specific implementations of virtualized RAN, these are not as universally applicable or pressing as the challenges associated with managing and troubleshooting such complex systems. The management and operational aspects often define the efficacy and reliability of virtualized RAN environments.
