The degree of 5G complexity at feature level is by no means any different from those of the previous generations; what makes it complex and challenging includes:
1) myriad of use cases and services, features and deployment scenarios that operators will have to design and configure their networks for and get full control over network and application performance;
2) by adding another ”G” to the pot, further complexity and challenges in managing network performance and quality of service will result across the “Gs ”;
3) operators will have to manage more data, different traffic types and a diverse set of applications and services, e.g. performance guarantee of network slices. As a consequence, operators need to transform operations by automating service provisioning, testing and management and using real-time insight to manage performance and customer experience.
4) new security landscape that could compromise operators’ networks and subscribers, and significantly impact 5G business plans dictating consistent automated and integrated security across network elements and services.
