4iG Group selects Nokia for network modernisation

September 19, 2025

4iG Group has signed an agreement with Nokia to modernise and unify its IP access and DWDM transport backbone networks in Hungary. The objective of the development is to establish a next-generation ready, energy-efficient, and secure network infrastructure that handles increasing data traffic, supports the growth of digital services, and ensures sustainable operations in the long term.

The collaboration of 4iG Group and Nokia is expected to commence later this year.

Leveraging Nokia’s network solutions, the new system delivers fast, stable and secure connectivity in supporting the country’s AI infrastructure buildout. This will satisfy both current and future capacity requirements, thereby establishing the bedstone for next-generation services including the substantial growth in connectivity needs driven by AI and data centre connectivity. In addition, the implementation of a fully automated, cloud-native service model enables service providers to deliver enhanced levels of service to both residential and enterprise customers.

“Our partnership with Nokia goes beyond technology: together we aim to build a network infrastructure that will strengthen our role in shaping the region’s digital development in the coming years. We are not just building a network but laying the foundation for an ecosystem in our customers and partners can plan their future with confidence and security,” said Péter Fekete, CEO of 4iG Group.

“Our collaboration with 4iG Group marks a significant step in advancing secure, high-performance connectivity across Hungary and our latest win in this region. As AI continues to reshape how industries and individuals consume digital services, building a robust, future-ready, secure network foundation is essential. Our shared vision with 4iG is to deliver a resilient, secure, energy-efficient, and scalable network that enables innovation and supports the digital ambitions of both businesses and communities,” added Matthieu Bourguignon, Senior Vice President for Network Infrastructure Europe, Nokia.

To enable the rollout of next-generation digital services, the new infrastructure is based on Segment Routing over IPv6 (SRv6), a future-ready routing technology and the latest generation of high-speed DWDM optical technology. At the same time, it remains fully compatible with existing optical and IP/MPLS-based systems. In addition to these, Software-Defined Networking (SDN) allows centralised configuration of network elements, optimising processes and reducing the risk of misconfiguration. This allows telecom operators to access network services in a fully automated, cloud-native environment.
