Hence, 5G systems are envisioned to become flexible and versatile network infrastructures that can be leveraged through a wide range of service-delivery models (e.g., neutral network hosting, network as a service, and private networks) and operators can customize for different applications and customer needs using network slicing.Peer Reviewe
