Open Network Index: 2025 results

Open networks redefine how telecoms networks are built and operated. They create a vendor-agnostic, cloud-based, AI-driven foundation for greater automation, innovation and strategic independence. Telecoms operators have been on a long journey to achieve this vision, and they are now beginning to turn it into reality with tangible progress.

As the adoption of open networks in the telecoms industry grows, it is increasingly important to define and measure network openness to provide a clear benchmark for progress, foster ecosystem alignment and ensure that open networks fulfil their transformative potential.

Analysys Mason, in partnership with Dell, conducts an annual longitudinal study to understand operators’ strategies for open networks and measure their progress towards deployment. The results form our Open Network Index (ONI).

This report is based on the results of the 2025 edition of the ONI, using data from a survey of 50 leading Tier 1 operators worldwide, conducted between December 2024 and January 2025. It assesses the progress and key changes in operators’ open network transformations since the ONI 2024.1 In addition, the scope of the ONI has been expanded to include operators’ AI strategies in the network.
