Europe's 6G KVI Research Moves from Vision to Real-World Evidence

For several years, discussions about 6G have focused on ambitious technical improvements such as higher data rates, lower latency, improved energy efficiency, integrated sensing and artificial intelligence. However, an equally important question is whether these improvements will translate into meaningful benefits for people, businesses and society. This is where Key Value Indicators (KVIs) come into the picture.

We have previously explored this topic on Free 6G Training, including our article on The 79 Projects Shaping Europe's 6G Vision with KPIs and KVIs. That article looked at the European Smart Networks and Services Joint Undertaking (SNS JU) research programme and how Key Performance Indicators (KPIs) and KVIs are being used to guide the development of future networks.

A new October 2026 white paper, titled 6G KVIs – SNS Projects Target Values and Survey Results 2026, takes this discussion further. Produced through the 6G-IA Test, Measurement and Validation Working Group, the 110-page report brings together updated definitions, targets, evaluation methods and early experimental results from European 6G research projects. More importantly, it shows how researchers are beginning to move from discussing the potential value of 6G towards actually measuring it.

To briefly recap, KPIs measure the technical performance of a network, including throughput, latency, coverage, reliability and energy consumption. KVIs attempt to measure the wider benefits of that performance, such as improved quality of life, reduced environmental impact, economic productivity, digital inclusion and trust. A faster network is a technical achievement, but whether that speed improves healthcare, reduces water consumption or helps businesses operate more efficiently is a different question.

The new report continues to use the 12 Key Value families established in earlier research, covering environmental, societal and economic sustainability alongside areas such as privacy, trust, knowledge, digital inclusion and personal health. Rather than introducing another set of definitions, the focus is increasingly on connecting these values to measurable results.

One of the most interesting examples comes from the 6G-PATH project, which has been conducting trials across several sectors. In a precision-agriculture use case, the project reported a 42% reduction in water consumption against an initial target of 10%. The research connects technical capabilities such as reliable video transmission, sensing accuracy, uplink capacity and edge processing with better detection of crop water requirements and more precise irrigation.

This is a useful illustration of the difference between KPIs and KVIs. The technical performance of the communications system is important, but the actual value comes from using that system to reduce unnecessary water consumption. At the same time, this is an early project-specific result, and it would be misleading to attribute the entire saving to 6G connectivity alone. The sensors, analytics, application design and farming practices all contribute to the outcome.

Healthcare provides another example. The 6G-PATH project reports a fall-detection use case that achieved an alert latency below two seconds, alongside positive user feedback on emergency response and quality-of-life benefits. Here, the relationship between technical performance and societal value is relatively easy to understand. Faster and more dependable detection can enable quicker intervention, potentially improving patient safety. Nevertheless, the longer-term health benefits still need to be demonstrated through broader deployment and evaluation.

Perhaps the most revealing finding in the report comes from a public protection and disaster relief (PPDR) use case. Despite experimenting with advanced communications technologies, the majority of respondents reported low satisfaction because established TETRA/TETRAPOL systems performed better in the tested context.

This highlights an important point that is sometimes overlooked in discussions about future networks. Introducing newer technology does not automatically create additional value. For mission-critical users, reliability, availability and predictable behaviour may matter considerably more than peak data rates or other impressive technical specifications. A system that fails to meet the performance expectations established by existing technology may actually reduce trust and user acceptance.

The report consequently identifies reliability as a fundamental condition for realising value, rather than simply another technical metric. Improvements in speed and latency may be useful, but they cannot compensate for unreliable service when the application depends on continuous connectivity.

Economic sustainability is another important area of research. Projects are examining whether future networks can reduce capital expenditure (CAPEX), operational expenditure (OPEX), manual effort and service delivery costs, while also creating new business opportunities.

For example, SUNRISE-6G reports that more than 80% of surveyed users believe that reductions in CAPEX and OPEX are achievable through advanced 6G technologies. A similar proportion believe that productivity improvements exceeding 20% are possible compared with 5G baselines. These are encouraging findings, but they represent stakeholder expectations rather than verified financial savings.

Other projects are introducing more specific targets. The iTrust6G project, for instance, defines measurable objectives for faster security operations, reduced manual workload, improved threat response and stronger network availability. By linking operational measurements with outcomes such as reduced user burden and increased trust, such work provides a more structured basis for evaluating the benefits of automation.

Artificial intelligence is also becoming increasingly important in this research. AI-assisted network management, automated orchestration, distributed intelligence and edge computing are being examined as ways of improving efficiency, resilience and service delivery. However, AI introduces additional concerns about fairness, transparency, explainability, accountability and privacy. The report recognises that technical improvements alone are insufficient if users cannot trust the systems making decisions on their behalf.

Despite these advances, measuring societal value remains challenging. Some outcomes, such as reduced water consumption, energy savings or faster emergency alerts, can be measured relatively directly. Others, including digital inclusion, improved wellbeing, social trust and wider economic benefits, are much harder to quantify. They often depend on factors beyond the communications network, including organisational practices, user behaviour, local conditions and public policy.

The report also identifies a significant lack of consistency between projects. Different research teams use different definitions, baselines, questionnaires and validation methods, even when investigating similar values. This makes meaningful comparisons difficult. A positive user-satisfaction result in one trial, for example, cannot necessarily be compared directly with a result from another project using a different assessment method.

The authors therefore emphasise the need for more harmonised evaluation frameworks, common benchmarks and longer-term validation. They also acknowledge that early trials are primarily useful for testing measurement methods and identifying promising relationships, rather than proving that widespread deployment of 6G will deliver particular societal outcomes. The white paper itself is a research survey, not a set of mandatory KVI requirements or certification benchmarks.

In our view, this is an important development in the evolution towards 6G. The industry has become very good at measuring communications performance, but demonstrating the wider value of connectivity remains more difficult. The European research initiatives are beginning to address that gap by combining technical measurements with user feedback, operational results and environmental or economic assessments.

There is still a long way to go before KVIs become sufficiently mature and consistent for widespread comparison. Nevertheless, the shift from defining desirable outcomes to testing how those outcomes can be measured is significant. Ultimately, the success of 6G should not be judged only by how much faster, more intelligent or more efficient the networks become, but also by whether those improvements deliver benefits that people, businesses and society can recognise and measure.
