For years, the telecom industry has fixated on two layers of connectivity: buried-fiber networks and orbit-based satellites. Yet, increasingly across Africa, the real game-changer for sustainable, cost-effective, and resilient connectivity is neither ground nor space, it is microwave and wireless technology.
Unlike fiber, which requires heavy investment, lengthy deployments, and complex rights-of-way, and satellites, which face high operating costs and latency issues, microwave solutions offer a faster and more flexible alternative. They deliver high-capacity connectivity across diverse terrains and underserved regions with greater efficiency and adaptability.
Operators that rely solely on fiber leave their networks vulnerable. A single line cut can bring entire systems to a halt. Microwave and wireless technologies not only provide robust primary connectivity but also serve as an essential layer of redundancy to maintain uninterrupted service. More importantly, they stand out as powerful enablers of digital inclusion, bridging the connectivity gap in rural areas, remote communities, and challenging terrains where fiber is impractical and satellite remains costly.
In Africa, where terrain, regulatory environments, cost-structures, and deployment timelines vary dramatically, microwave and wireless backhaul, fronthaul, and access solutions are not second-best; they are strategic.
Why Microwave and Wireless Matter Now
Several dynamics are converging to move microwave and wireless from “alternative” to “core”. Trenching fiber across long distances in remote or rugged terrain is expensive, time-consuming, and logistically challenging. Satellite remains a high-cost, high-latency solution. Microwave, by contrast, can be deployed quickly (months rather than years), with far lower capital outlays, and provides near-fiber capacity in many scenarios.
For example, Huawei’s 2025 Microwave Industry White Paper outlines how microwave is now evolving from strictly base-station backhaul to broad applications, including fiber-backup, enterprise private networks, and private lines. In Africa, the gradual liberalization of E-band spectrum is empowering operators to deploy high-capacity microwave links for short-haul applications.
Physical fiber cuts remain one of the largest causes of network outages in Africa. In contrast, microwave links offer flexible network architectures, serving as alternate paths, redundant routes, or even primary links with rapid failover capabilities. They are inherently less susceptible to disruptions stemming from excavation, civil works, or natural disasters, depending on the terrain.
Ericsson showcased this concept by delivering and deploying microwave E-band equipment for Safaricom’s transport network across Kenya. Todd Ashton, Vice President and Head of Ericsson East and Southern Africa, explained that by building an efficient microwave backhaul network with end-to-end performance, Safaricom achieved a “future-ready network with a new level of capacity, speed, and quality, allowing it to create and offer new services to customers and businesses.”
Rural, remote, and underserved regions across Africa frequently lack fiber connectivity due to high costs and challenging geographies. While satellite can fill some gaps, its expense often makes large-scale deployment impractical. Microwave and wireless networks represent the perfect solution to connect rural areas and remote villages that remain unserved by fiber or satellite.
Traffic demand across Africa is exploding, driven by video, mobile broadband, 4G/5G densification, fixed wireless access (FWA), and enterprise use cases. Microwave backhaul is no longer limited to hundreds of Mbps; multi-Gbps links are sprouting, linking the east and west coasts of Africa. For instance, Nokia’s trial with Algerian operator Djezzy achieved 8.5 Gbps over a 5.7 km microwave link. Notably, Huawei expects that more than 60% of mobile backhaul will still use microwaves, even in the 5.5G era.
Who’s at the Helm?
Huawei stands strong in its conviction that microwave is a core enabler of Africa’s broadband evolution, describing it as an “all-weather communication infrastructure” suited to diverse environments. The company’s advanced 5G microwave architecture delivers fiber-like capacity while reducing tower space requirements, reinforcing microwave’s role as both a foundation and backup for network resilience.
Ericsson continues to expand high-capacity microwave deployments with operators beyond Safaricom, such as AXIAN Telecom, through which the partners modernized Telma Madagascar and Tigo Tanzania’s networks in 2023. Its MINI-LINK 6600 provides efficient, scalable transport networks that support 4G and 5G transitions, particularly in regions where fiber deployment remains limited.
Nokia has demonstrated the potential of microwave carrier aggregation with Orange France in Europe, successfully delivering multi-gigabit backhaul capacity and proving that the technology can meet soaring data demands while accelerating network rollout in an African context.
Strategic Considerations for Operators in Africa
To apply global implementations to a localized context, operators should avoid a “single lane” mindset. Relying solely on fiber increases exposure to cuts, cost overruns, and delays. Similarly, relying solely on satellite garners higher OpEx and latency. As a result, many operators are increasingly adopting a hybrid model where fiber, microwave/wireless, and satellite each play defined but inter-linked roles. In this context, fiber is reserved for core rings and densified urban corridors, microwave for backhaul/transport in mixed terrain, wireless/millimeter-wave for last-mile or rural access, and satellite for ultra-remote or emergency fallback.
For operators calculating the best route from a cost perspective, the focus has pivoted to total cost of ownership (TCO) and speed of deployment in light of terrain, rights-of-way, power supply, backhaul needs, and future-proofing scenarios. Across Africa’s rural corridors, from Kenya, Ethiopia, Uganda, and DRC’s highlands, to the inland stretches between Nigeria, Niger, Ghana, and Burkina Faso, and down through cross-border routes such as Zambia–Malawi and Botswana–Namibia, microwave is proving to be more cost-effective than fiber.
Microwave performance, especially at E-band (70/80 GHz), or even higher, depends on the availability of spectrum and regulatory clarity. Having demonstrated clear technical advantages in 5G backhaul construction, E-band spectrum has been allocated in 86 countries, including eight in Africa, with Nigeria leading by opening up 70/80 GHz for terrestrial service providers.
The Rural Imperative: Inclusion Over Air
One of the most compelling arguments for microwave adoption in Africa is inclusion. The digital divide still looms large. Many communities lack broadband connectivity simply because fiber is too expensive or logistically unfeasible. Microwave links and wireless access, including point-to-multipoint and fixed wireless access, provide a bridge.
In rural corridors, a mobile tower may already have solar power and a microwave link can connect to the core network in weeks, rather than the months or years fiber might take. Once connected, local access, via wireless, WiFi, and fixed wireless access, can be delivered affordably.
From an operator perspective, this means that rural “last-mile” is no longer the barrier; the obstacle is the “middle mile” or transport/backhaul link. Microwave solves that. And once rural communities are brought into the fold, new service models can consequently emerge, such as digital health, agriculture platforms, IoT, remote education, local caching, content delivery networks (CDN), and so on.
Microwave’s adaptability also means that, as traffic grows, additional capacity is available via modulation upgrades, spectrum expansion, and the aggregation of further hops, culminating in “affordable first-mile, scalable future-mile” connectivity options.
Challenges and Mitigations
All technologies have caveats. For microwave and wireless deployments, these include:
- Line-of-sight (LoS) and Tower Infrastructure: Microwave links require clear paths, and tower infrastructure may need reinforcement or site access. Careful path planning, use of non-LoS or near-LoS technologies, horizon clearing, and multi-hop design will mitigate this.
- Interference and Spectrum Congestion: At lower microwave bands, there may be interference from other services. This is where licensed bands (E-band), link-budget margin design, and channel planning serve as solutions.
- Power and Reliability: Most sites in Africa lack stable power or backup, an issue that was highlighted at MWC Kigali 2025 and demands more attention, according to policy makers and investors.
By recognizing these issues and actively planning around them, operators can make microwave not just an interim solution but a strategic backbone.
Outlook and Strategic Recommendations
Looking ahead, key trends will shape how microwave/wireless takes center-stage in Africa’s telecom infrastructure.
Historically, microwave was seen as the “last resort” or backup to fiber. Now, microwave is being designated a primary transport option in many rural and suburban zones, with fiber reserved for high-density urban cores. Vendors are pushing 10 Gbps+ microwave solutions, and African operators are deploying them.
Fixed wireless access is gaining traction in Africa as a means to deliver broadband to homes and SMEs. But FWA requires robust transport links, exactly what microwave provides. Operators bundling FWA roll-out with microwave backhaul planning in Africa include MTN Group, Safaricom Kenya, and Vodacom South Africa.
Strategic Recommendations for Operators
Before implementing microwave and wireless solutions, using successful use cases as a point of reference, operators should conduct a transport audit, map node-to-core connectivity, and identify sites where microwave could reduce cost/time as opposed to fiber.
By designing hybrid architectures—merging fiber, microwave, and fixed wireless access, according to cost, terrain, and deployment timeframe—a robust implementation can be achieved.
Operators cannot deploy infrastructure with only today’s demand in mind. The traffic growth curves, densification of 4G/5G, FWA, IoT, and enterprise connectivity all point to escalating backhaul/transport needs. Microwave vendors are already delivering 10G+ and even trialing D-band (130-175 GHz) for ultra-capacity. To ensure continuity, operators should choose microwave systems that support capacity upgrades to handle future traffic and opt for parallel microwave paths or ring architecture to achieve resiliency alongside fiber networks.
The Overlooked Backbone
African telecom operators are navigating mounting pressures, from CapEx limitations and rapid traffic growth to rural inclusion mandates, sustainability goals, and fierce competition, making infrastructure choices more strategic than ever. While fiber remains essential and satellite retains its niche, the true catalyst for scalable, resilient, and cost-effective connectivity lies in microwave and wireless technologies, as demonstrated by Huawei, Ericsson, and Nokia, and their affiliated partnerships.
Africa’s connectivity will be defined not by what’s buried underground, but by what travels through the air, across towers, antennas, and wireless links. This is the pathway to bridging the digital divide, powering 5G and 6G services, and realizing the continent’s full digital potential.
