5G Intricacy - Pivotal Technical Aspects

The diagram below provides a high-level overview of the major technical aspects of 5G that differ significantly from the previous generations, in particular from 4G. It is apparent that 5G will introduce not only, due to its service based architecture, new challenges but also a deployment paradigm significantly diverse and in a way quite inhomogeneous that in its own right poses new/unknown (!) challenges that for sure will be surmountable but will take time and fatalities!

In 2019, we will carve up the technical aspects shown below from various perspectives and shed lights on the comments made above.

5G Intricacy

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.
