Which aspect of Cloud RAN contributes to flexible scaling?

The aspect of Cloud RAN that contributes to flexible scaling is the abstraction of hardware resources through virtualization. This feature allows network resources to be decoupled from the hardware on which they run, enabling dynamic allocation and scaling based on demand. By employing virtualization, operators can effectively manage resource utilization, deploying additional computational power or storage as required without being constrained by physical hardware limitations.

Virtualization enables the deployment of network functions on general-purpose hardware, allowing operators to scale resources up or down quickly and efficiently in response to varying traffic loads or service requirements. This flexibility is crucial for adapting to changing conditions and optimizing network performance in real-time, which is essential in a modern telecommunication environment where demand can fluctuate significantly.
