A pragmatic assessment of Open RAN deployments in Africa — where it works, where it doesn't, and how to make the transition successfully.
Radio Access Network architecture is entering a new phase. For decades, mobile operators deployed RAN using tightly integrated solutions from a small number of vendors. This traditional model delivered stability and performance, but it also created vendor dependency, high upgrade costs, and limited flexibility.
Open RAN proposes a different approach. It introduces open interfaces, disaggregated hardware and software, virtualization, and intelligent control. The O-RAN Alliance defines its mission around transforming RAN toward open, intelligent, virtualized, and interoperable networks, with specifications covering AI RAN, open interfaces, functions, and procedures. Telecom Infra Project's OpenRAN program supports disaggregated and interoperable 2G, 3G, 4G, and 5G NR RAN solutions based on service provider requirements.
For African operators, the promise is attractive. Open RAN can diversify the vendor ecosystem, reduce dependency on proprietary platforms, support rural coverage models, and create more room for local integration and innovation. It can also align with software-defined operations and AI-driven optimization.
MTN's OpenRAN communication is a useful reference for Africa. The group highlighted OpenRAN as a way to modernize radio networks, expand 4G and 5G coverage, reduce power consumption, and diversify vendor dependency. MTN also stated that radio access networks represent a major part of mobile operators' capital and operating costs, making innovation in RAN architecture strategically important.
However, African operators should be pragmatic. Open RAN is not a universal replacement for traditional RAN in every scenario. Traditional RAN still has strengths: mature integration, optimized performance, established support, and predictable behavior in dense urban networks. In high-capacity environments, where spectrum efficiency and operational stability are critical, traditional integrated RAN may still be the safer choice.
Open RAN is more compelling in targeted scenarios. It can be useful for rural coverage, private networks, greenfield deployments, neutral-host models, enterprise campuses, and selective modernization projects. It can also help operators test new vendors without replacing the entire network.
The key challenge is integration. Open RAN introduces more components: radio units, distributed units, centralized units, RAN intelligent controllers, orchestration platforms, cloud infrastructure, and transport requirements. More openness means more interoperability testing. Operators must ensure that performance, synchronization, timing, security, and lifecycle management are validated end to end.
Security also deserves attention. Open interfaces create flexibility, but they also expand the architecture's exposure. Operators need strong hardening, certificate management, secure APIs, vulnerability management, and vendor accountability. Open RAN must be engineered as a secure telecom platform, not simply assembled from components.
A practical African Open RAN strategy should follow four steps:
- Select the right use case. Rural sites, enterprise private networks, or controlled greenfield zones are often better starting points than critical dense urban macro layers.
- Build an integration lab. Operators should test interoperability, performance, timing, failure recovery, software upgrades, and monitoring before field deployment.
- Define the operating model. Open RAN requires skills in cloud infrastructure, IP transport, Kubernetes or virtualization, automation, and security.
- Maintain a hybrid approach. Traditional RAN and Open RAN can coexist. The objective is better economics, flexibility, and coverage.
For Africa, Open RAN's value is not only technical. It can support a more diverse telecom ecosystem: local system integrators, local engineering skills, regional labs, and more competitive procurement. But success will depend on discipline. Operators that treat Open RAN as a shortcut may face complexity. Operators that treat it as a structured transformation can create long-term advantage.
ODDnet's view is balanced: Open RAN is promising, especially for targeted African deployment models, but it must be validated, secured, and integrated with the same rigor as any carrier-grade network.
