In addition to facilitating network automation, O-RAN provides several benefits, including:
* Agility in software-enabled architecture unification makes network suitable for existing, past and future generations;
* Deployment flexibility for disaggregation and software association makes the network flexible for installation, update and extension;
* Real-time responsiveness, since vRAN is service-specific network-oriented software that behaves based on the intended service to real-time services and requires very low latency from less critical services;
* Reduction in operating costs by estimating the plug-and-play feature of O-RAN; modern learning methods can reduce the maintenance cost dramatically when compared with traditional solutions. \\ \hline \hline \end{tabular}
