Should nations prioritize the development of new military communication and drone technologies?
NATO recently concluded its Digital Backbone Experimentation 2026 exercise in Latvia, testing 5G network slicing and resilient communications across multi-national forces. The event, which involved over 60 technology partners, focused on operational interoperability for grey-zone security scenarios.
Why it matters
The experiment accelerates the integration of private 5G and satellite infrastructure into defense networks to ensure data continuity during signal disruptions. This focus on resilient, scalable connectivity is critical for managing potential grey-zone threats that fall below the threshold of traditional military conflict.
The exercise validated the use of a private 5G network slice on host-nation mobile infrastructure to maintain data transmission. This approach was tested alongside satellite links and troposcatter links—a method for transmitting data over long distances via atmospheric scattering—to ensure failover reliability.
The players
NATO
An intergovernmental military alliance currently prioritizing digital modernization and multi-domain operational interoperability.
LMT Defence
A defense technology firm that served as the technical integrator for the Digital Backbone Experimentation 2026 exercise.
General Alexus G. Grynkewich
The SACEUR leader who visited the exercise site in Latvia to review the integration of new communication technologies.
Edgars Rinkēvičs
The President of Latvia who met with military leadership to discuss the outcomes of the multi-national technological experiment.
European Union
A political and economic union currently planning the 2027 rollout of pilot European Drone Technology Hubs.
The details
The Digital Backbone Experimentation 2026 exercise utilized mobile 5G infrastructure to create a dedicated network slice, providing a secure, virtualized path for military traffic. To ensure data persistence during potential jamming, engineers integrated satellite communications and troposcatter links as redundant channels. LMT Defence, the technical integrator, coordinated these efforts across the participating national forces to test interoperability. The experiment specifically addressed passive object detection and resilient communications against electronic interference.

The Tech Race
This exercise reflects an ongoing effort to bridge the gap between commercial 5G innovation and the requirements of secure, high-resilience military communication architectures. It aligns with broader international initiatives to standardize interoperability for unmanned systems and data backbones in contested environments.
The transition to private 5G network slicing for military applications provides a blueprint for secure, high-speed data transmission in civilian sectors facing infrastructure instability. Industry partners and regional security stakeholders should monitor the 2027 launch of the new European drone hubs for emerging technical standards.
The takeaway
NATO is successfully shifting its technical strategy toward modular, software-defined networks that can survive intermittent link availability. Observers should track the 2027 opening of the European Drone Technology Hubs to see how these experimentation results translate into regional operational standards.
What happens next
The establishment of two pilot European Drone Technology Hubs in Latvia and the Netherlands is scheduled for 2027.
