Africa’s mobile and internet revolution is only just beginning, but one technical limitation could define the next decade of connectivity: low-band spectrum. Unlike high-frequency bands, low-band spectrum (typically below 1 GHz) travels farther and penetrates buildings better, making it the backbone for wide-area, reliable mobile coverage. For Africa, where vast rural areas and underdeveloped infrastructure dominate, access to low-band spectrum matters more than in almost any other region.
The continent’s geography and population distribution make this spectrum critical. Many countries have large rural populations scattered over wide areas. High-band spectrum — like 3.5 GHz or millimeter-wave 5G bands — can deliver high speeds, but only over short distances and with line-of-sight deployment. Without sufficient low-band spectrum, operators cannot economically provide consistent mobile broadband to rural communities, leaving millions digitally isolated.
Low-band spectrum also enhances affordability and inclusivity. Wider coverage reduces the number of cell towers needed to connect a population, lowering operational costs for mobile operators. This, in turn, can make mobile data plans cheaper and more accessible, which is crucial for Africa, where a significant portion of the population remains price-sensitive. Countries that efficiently allocate low-band spectrum enable more people to access education, financial services, healthcare, and commerce online.
Another factor is 5G adoption. While urban areas in developed countries can rely heavily on mid- and high-band 5G for speed, Africa needs low-band 5G first to provide stable, widespread coverage. Without it, the benefits of 5G — IoT, smart agriculture, telemedicine, and industrial applications — remain largely concentrated in cities, exacerbating the digital divide.
Regulatory allocation is also a challenge. Many African nations have yet to auction or free up sufficient low-band spectrum for mobile operators. Delays in releasing this spectrum not only slow digital infrastructure development but also limit competition and innovation. Countries that prioritize low-band spectrum now can accelerate rural connectivity and position themselves as attractive markets for investment in next-generation technologies.
Finally, the COVID-19 pandemic and rapid digital adoption have exposed the urgent need for reliable internet everywhere. From remote learning to mobile banking and e-commerce, the pressure on networks is higher than ever. Low-band spectrum is the most efficient way to ensure that even hard-to-reach communities stay connected in times of critical demand.
In short, low-band spectrum in Africa is not just a technical detail — it is the foundation for digital inclusion, economic growth, and technological leapfrogging. Allocating it wisely could determine which nations close the connectivity gap and which remain on the sidelines of the digital economy.
