It’s arduous for many people to think about a world with out prompt, limitless web entry. Some have even argued that it ought to, alongside entry to scrub water and electrical energy, be thought-about a basic human right.
However the truth is solely 64.4% of the global population as of January 2023 are web customers. Asia and Europe are dwelling to most people who’re related.
Africa is available in third. Nevertheless, accessibility varies wildly throughout the continent. About 66% of individuals in southern Africa are web customers. In east Africa the determine is 26%; it’s simply 24% in central Africa. Folks in rural areas have far much less entry than these within the continent’s city areas.
Web entry opens up the world in some ways. It will possibly entertain, educate, allow funds and even bolster democracy.
That’s why advances in offering web entry to individuals in Africa are value celebrating. In January 2023, the US firm SpaceX, which manufactures and launches spacecraft and communication satellites, announced that its Starlink service was obtainable in Nigeria. This was a primary for the continent. It has additionally since grow to be obtainable in Rwanda.
Starlink is a satellite-based web service. It’s set to be rolled out elsewhere on the continent, together with the Democratic Republic of Congo (DRC), Kenya and Tanzania, later this yr. Extra protection is to return in 2024.
This might be an necessary technique to fill Africa’s connectivity gaps, which have arisen due to poor digital infrastructure and the excessive prices of investing in fibre optic cables or cell phone masts, notably in rural and distant areas. The United Nations has a strategy for reaching common entry throughout Africa by 2030, however this gained’t be attainable with out modern approaches.
Starlink is one such innovation. Since all its customers are tapping into the identical infrastructure, in area, there’s much less want for erecting cell phone masts or laying fibre optic cable on land.
Starlink is a community of 1000’s of satellites situated near the Earth – about 550km from the planet’s floor – that present broadband web entry.
After all, satellites are already used for web connectivity. However a conventional web satellite tv for pc is a single geostationary object; its place in orbit is fastened in relation to the Earth. These satellites are additionally situated greater than 35,000km from Earth, so it takes a very long time for the sign to succeed in the top person. As anybody who has tried to make use of the web in a distant space is aware of, the additional a sign travels, the more serious it will get, so conventional web satellites are typically gradual and could be unreliable. They aren’t in a position to adequately help actions like reside streaming, on-line gaming and video calls.

Starlink’s Low-Earth Orbit satellites are in a position to interconnect and relay alerts between one another, creating quick, steady web service. There are additionally a number of them: on 17 February 2023, SpaceX said it had launched 3,981 satellites in complete, with 3,639 at present operational.
The corporate can launch its personal satellites on demand and replace them with the newest know-how as required, which it says adds to their reliability.
A lot of Africa’s web entry is at present being supplied by cellular, wi-fi web – alerts are relayed from land-based towers. This has much less protection and is slower than satellite tv for pc web entry.
One space of concern with regards to Starlink is the associated fee. For instance, originally of February 2023, FiberOne, a broadband web supplier in Nigeria, was providing web with speeds of as much as 500Mbps, which is quick. The set up payment was N32,231 (about US$70) and the month-to-month subscription value round N100,000 (US$220). Starlink in Nigeria, in the meantime, costs about N276,000 (US$599) once-off for the equipment and set up, then fees a month-to-month subscription payment of about N198,000 (US$43).
Starlink is cheaper in the long run than each fibre optic and cellular web suppliers. However can an average rural Nigerian household with a month-to-month earnings of lower than N28,000 (US$60) afford it? On condition that common incomes are equally low in most rural and distant components of Africa, there’s a danger that Starlink’s focused customers on the continent gained’t be capable of use the service.
Analysis makes use of
These issues apart, there’s little question that quicker web can propel Africa ahead. Regardless of the shortcomings of cellular, wi-fi web, it has been credited with greatly advancing Africa technologically. Providers like Starlink may gas even better progress in a number of areas. These embody schooling, participation in democracy and governance, catastrophe danger discount and mitigation, well being, and agriculture.

As a researcher in planetary and area science whose work includes, amongst different issues, the usage of satellite tv for pc information for monitoring and modelling in relation to geology, I’m particularly within the methods these satellites might be used past web entry, for duties like remote sensing and Earth observations. I hope that Starlink’s arrival in Africa will assist usher the continent into a brand new section of technological improvement.
For example, satellite tv for pc pictures may give info on crop yield, serving to farmers to make higher selections on irrigation, fertilisation and harvesting. In addition they enable for widespread and efficient monitoring of reservoir ranges, in addition to growing transparency about how a lot water is out there, thereby offering early warnings of shortages and uniform information amongst nations with widespread water sources.
Governments, researchers and industries should purchase entry to specialised Starlink satellites referred to as Swarm for information they want for these sorts of tasks. The sheer quantity and velocity of Starlink’s satellites means they will collect a number of information, shortly, and supply frequent updates. Starlink’s arrival in Africa is a good alternative for the continent’s scientists, governments and industries to collaborate.
