1 Scope
th
The fixed network has developed to the 5 generation and many new use cases have been introduced. Some supporting
technologies have been standardized and commercialized (e.g. XGS-PON and Wi-Fi 6), but enhancement and
optimization may be needed to implement the new use cases. These gaps need to be identified and addressed in
corresponding technical specifications.
The present document studies the technology requirements for the F5G use cases, explore existing technologies, and
perform the gap analysis. The technology landscape of F5G will be defined addressing also the relevant SDOs.
