Next generation fixed networks
Defining the fifth generation of Fixed Networks that will complement the success of 5G, 6G and future mobile systems.
Our standards are foundational to the evolution of converged IT and telecommunication networks, enabling operators and service providers to optimise performance, enhance energy efficiency and reduce operating costs.
Why standards matter
ICT networks are becoming smarter and more autonomous, complementing the progressive evolution of mobile systems. Our standards reinforce the flexibility, sustainability, reliability and cost efficiency of today’s ICT infrastructures, embracing the opportunities of technology trends like cloud, edge and virtualisation to address tomorrow’s industrial and societal challenges.
Key activities and focus areas
Network virtualisation
Facilitating development of an open, interoperable ecosystem, enabling lifecycle management of virtualised network functions hosted on independently deployed and operated NFV infrastructure platforms.
Zero-touch networks
Evaluating requirements, defining specifications and demonstrating technologies for tomorrow’s zero-touch networks.
Sustainable ICT
Collaborating with industry stakeholder to enable the implementation of efficient and interoperable ICT services, increasing the sustainability of networks and devices, and improving the efficiency of energy management and ICT waste management.
