Industry Specification Group (ISG) Fifth Generation Fixed Network (F5G) Activity Report 2020
Chair: Luca Pesando (Telecom Italia)
Studying the evolution of the fixed network needed to match and further enhance the benefits that 5G has brought to mobile networks and to communications; defining improvements with respect to previous solutions and new characteristics of what represents the 5th generation fixed network.
We are entering a new era of communications where the evolution of fixed networks will play a vital role in the success of 5G and future mobile systems. Building on previous technology iterations, this ‘fifth generation’ of fixed networks will target three main goals of delivering full-fibre connection, enhanced fixed broadband and a secure, low-latency, reliable experience in both industrial and consumer applications.
For home scenarios, emerging services such as Cloud VR (virtual reality) and AR (augmented reality) video streaming or online gaming introduce the necessity for ultra-broadband, extremely low latency and zero packet loss. Business scenarios such as enterprise Cloudification, leased line, or POL (Passive Optical LAN) require high reliability and high security. Other industry sectors have specific requirements on the deployment of fibre infrastructures, including environmental conditions such as humidity, temperature or electromagnetic interference.
In February 2020 ETSI launched its Industry Specification Group dedicated to specifying the fifth generation of Fixed Network (ISG F5G). The group aims to study the fixed-network evolution required to match and enhance the benefits that 5G has brought to mobile networks and communications. It will define improvements with respect to previous solutions, opening up new opportunities by applying fibre technology to various scenarios and turning the ‘Fibre to the Home’ paradigm into ‘Fibre to Everything Everywhere’.
Issued in September 2020, a White Paper authored by ETSI members [ETSI White Paper #41] sets the scene for the evolution of on-premise, fixed access, and aggregation networks. The paper offers a general description of the main features and characteristics of ISG F5G, plus benefits in terms of network simplification, cost-efficient ODN buildout and end-to-end management,
Published in December 2020, the group’s first Group Report [GR F5G 001] examines the history of fixed networks and summarizes their development paths and driving forces, analyzing factors influencing the definition of fixed, cable and mobile network generations. It also explores the path of fixed network evolution, including transport, access and on-premises networks.
The group’s second deliverable, a further Group Report [GR F5G 002] detailing use cases for the 5th generation fixed network for both consumers and enterprise organizations, was completed and submitted for approval before the end of the year.
Other work items in development include: a specific collection of use cases/requirements for PON (Passive Optical Networks) for industrial applications; a technology landscaping and gap analysis document highlighting the requirements for F5G networks; network architecture; end-to-end management; and Quality of Service aspects for demanding services such as 8K video, interactive gaming and VR/AR.
