Network Transformation from 4G to 5G
The evolution from traditional 4G to 5G is one of the few big challenges facing the telecom industry in the coming years. New 5G technology is expected to introduce flexibility and agility in the network that will address the needs of different services and industry verticals.
This course addresses and analyses the different strategies that can be utilised to transform network based on 3GPP R15. It covers an overview of the current situation on 4G or LTE networks, and the different options for migration to achieve final 5G solution in the radio access and core. In short, the network transformation applies end-to-end, on 5GC as well as NG-RAN.
Participants will understand the steps to migrate 5G RAN from Non Standalone (NSA) to Standalone (SA) using different flavours. It introduces cloud solutions in the RAN. For the Core network part, participants will learn a new solution called SBA (Service Based Architecture) and how to achieve maximum automation.
The course provides key features and functionalities of 5G New Radio (NR) and 5G Core Network, such as split architecture of NG-RAN, cloud RAN options, CUPS, Dual Connectivity and complementary technologies like network slicing, MEC as well as automation and orchestration.
Finally, this training presents an overview of network evolution and how to achieve network automation through technologies such as SDN and ONAP.
This course is designed for Network Design Engineers, Network Planning Engineers, Network Operations and Maintenance, Managers in the Radio and Core, and anyone interested to acquire knowledge of the 5G technology.
