Private 5G networks adopt a lightweight architecture for industry: vRAN and 5G Core in the edge era Published on 28 September 2026 by Christ-loisele (3 min read)
Private 5G networks now integrate hybrid solutions combining lightweight virtualization and edge computing, with technologies such as vRAN and 5G Core optimized for critical industrial applications. This evolution addresses the needs for ultra-low latency and enhanced security of businesses, while simplifying their deployment.

Private 5G networks are evolving toward more agile and resource-efficient models, relying on components such as vRAN (Virtualized Radio Access Network) and 5G Core . Unlike traditional infrastructures, these solutions enable businesses to deploy dedicated networks with near-instantaneous latency and massive connectivity for IoT, while ensuring complete control over their security and data.
According to the Ubuntu blog , this hybrid approach combines the advantages of public and private networks: it provides unified connectivity, optimized services, and customizable security within a defined perimeter. For example, a factory or port can thus isolate its critical communications while benefiting from performance tailored to its specific needs, such as robot synchronization or managing connected fleets.
Private 5G networks allow businesses to control and secure their own data while optimizing their infrastructure for exclusive needs, a revolution for demanding industrial sectors.

Deploying private 5G networks at the edge presents major technical challenges, particularly in terms of energy consumption, cooling, and physical space. To address these, the industry is turning to lightweight virtualization solutions, such as system containers and KVM virtual machines optimized for lightweight kernels. These technologies, combined with tools like MicroCloud (which integrates LXD for containers, MicroCeph for storage, and MicroOVN for networking), enable the creation of autonomous and automated private cloud environments, suited to edge constraints.
Ubuntu emphasizes that these architectures reduce complexity while improving responsiveness. For example, a real-time kernel such as the one integrated into Ubuntu with PREEMPT_RT ensures the predictability essential for latency-sensitive workloads, such as industrial control systems or real-time augmented reality applications.
Performance close to raw hardware
To achieve performance levels comparable to those of dedicated hardware, private 5G deployments leverage advanced techniques such as DPDK (Data Plane Development Kit) , eBPF (extended Berkeley Packet Filter) , and XDP (eXpress Data Path) . These tools accelerate network packet processing, essential for applications like real-time 4K video or managing massive IoT data streams. Additionally, hardware features such as NUMA awareness (Non-Uniform Memory Access), hugepages , CPU affinity, and SR-IOV (Single Root I/O Virtualization) enable network functions and AI workloads to achieve performance close to bare metal.
These optimizations are crucial for sectors like healthcare, where connected medical devices require latency below one millisecond, or the food industry, where real-time traceability of production lines depends on ultra-reliable networks.
What this changes here
For businesses and government agencies in Benin and West Africa, the adoption of private 5G networks could transform strategic sectors such as autonomous ports, special economic zones, or smart electrical grids. For example, a port like Cotonou could deploy a vRAN to synchronize automated cranes and container management systems in real time, thereby reducing waiting times and logistical errors. Hospitals, on the other hand, could secure their medical data exchanges with isolated 5G Core networks while benefiting from AI-assisted diagnostics with minimal latency.
Lightweight virtualization solutions, such as those offered by MicroCloud, would also allow local SMEs to equip themselves with private networks without investing in costly infrastructure. Governments, meanwhile, could secure sensitive data (such as voter registries or mobile payment systems) by leveraging confidential computing technologies and transactional updates via Ubuntu Core, thereby limiting cyberattack risks.
Finally, integrating these networks with local resource management tools, such as sovereign cloud solutions under development in West Africa, could accelerate adoption while respecting digital sovereignty constraints.
