1 Scope
The present document describes the use cases to be enabled by the F5G Advanced network. The use cases in the present
document include services and applications for residential users, enterprises, vertical industries, network operation
optimizations, and evolved fixed end-to-end infrastructure, which were not supported by the F5G network. Use cases
will aim to introduce new technical requirements for the F5G Advance network along various characteristic dimensions.
The use cases will be used as input to F5G Advanced Technology Requirements and Gap Analyses activities to extract
technical requirements.
