Which key performance area does 'user experience' in Cloud RAN focus on?

Focusing on 'user experience' in Cloud RAN highlights the importance of both quality of service and customer satisfaction. This area addresses how effectively the network delivers services that meet or exceed user expectations. User experience encompasses factors such as network reliability, responsiveness, and overall service quality, which directly impact how customers perceive and interact with the network.

Quality of service pertains to the performance characteristics of the telecommunications service, including data throughput, latency, and availability. These elements collectively influence customer satisfaction, as users are more likely to remain loyal to a service provider when they consistently receive high-quality experiences. Hence, 'user experience' is not just about speed but also about an encompassing service experience that ensures user needs are met effectively.

In contrast, while other areas such as server uptime and cost reduction are important operational metrics, they do not directly focus on the overall user experience as seen through the lens of service quality and satisfaction.
