Fiber Optic Cables and the Coming 5G Revolution

In the near future, Nigeria, like every other country, will require the mass adoption of fifth-generation (5G) technology to get ahead. To achieve this, it will require supporting infrastructure.

Here, we explore why fiber optic cables are a crucial part of this infrastructure, one that Nigerian homes, districts, and cities should acquire.
In recent times, there’s been much talk about 5G technology and the possibilities that it could afford its users. The world anticipates the coming revolution that it will bring: ultra-fast connectivity, a much greater number of connected devices, and support for the Internet of Things (IoT).
Coincidentally, concrete moves towards testing and rolling out 5G across the world have come at the same time with a global spike in the demand for data-hungry services. This event, involving the increased use of video-streaming and video teleconferencing applications, has been driven by the COVID-19 pandemic and the restrictions on physical meetings that have come in its wake.
Nigeria has shown much enthusiasm about 5G. In 2019, it became the first country in Africa to initiate 5G network trials. And in May 2021, its upper legislative house approved the deployment of the technology nationwide.
However, a crucial question remains: do Nigeria’s homes, businesses, districts, and cities possess the infrastructure required for them to make the most of the technology?
5G Network Infrastructure: The Existing Gaps
5G infrastructure consists of a network of large and small cell base stations that possess the edge-computing capabilities needed to make 5G cellular networks functional.
The main infrastructure includes 5G small cell infrastructure and Radio Access Network (RAN) towers. Multiple-input, multiple-output (MIMO) antennas also have to be deployed in large numbers; fiber optic cables play a role as well.
How the Infrastructure Work as a Whole: The service area of 5G networks is divided into cells. Devices in each cell communicate through radio waves with local antennas, transmitters, and receivers. The antennas are connected to transmission electronics, which are in turn connected to switching centers in the telephone network by optical fiber.
Due to the costs involved in building new infrastructure from scratch, 5G is often made to utilize existing structures that have served older generation networks. However, some components may have to be upgraded or replaced for the technology to function as it’s designed to.
One of these components is cabling. In the past, 2G and 3G had relied on copper coaxial cables for carrying telecommunication signals over their networks. The bandwidth demands of 4G meant that they became less desired as a cabling option. They will be unable to support the even higher demands of 5G.
Why Fibre Optic Will Be Important for the 5G Revolution
As has already been hinted at, the major drawback for coaxial cables is the limited speeds that they can support. Until fairly recently, they were adequate for the 3G-dominant telecommunications landscape. But they have since fallen out of favour in quarters seeking faster speeds.
Coaxial cables can achieve speeds of between 10Mbps (Megabytes per second) and 1Gps (Gigabyte per second) and have recorded upload speeds of between 3Mbps and 50Mbps. Optical fiber, on the other hand, can attain speeds exceeding 10Gbps.
A major factor contributing to these differences in speed is the type of transmission carried out by coaxial and fiber optic. While optical fiber transmits signals as light, coaxial moves them in the form of electrical signals. The medium through which they are transmitted plays a role too. Optical fiber is made of glass and plastic; coaxial is primarily made of copper.
When compared to the telephone network generations they are supposed to support, it becomes clear why fiber optic cables are the preferred option for 5G. For instance, 3G devices can connect to the internet at a maximum speed of 21Mbps; 5G speeds can reach 1Gbps.
5G, Fibre Optic, and Last Mile Solutions
Earlier in this article, we referred to the benefits of 5G that homes, districts, and whole regions could access in the near future. Smart buildings, communities, and cities will become a reality, and high-speed connectivity will enable the integration of various economic sectors and drive innovative business models.
As has already been emphasized, the older copper-based transmission lines will not be able to keep up with the data demands of this new reality. Homes already utilizing this older technology may have to upgrade to fiber-optic cables if they are going to enjoy the comforts that 5G will bring.
The smart home will need much faster speeds to make its data-hungry, data-churning environment function optimally. Fiber optic cables could be one of the pillars on which a domestic, fully operational Internet-of-Things (IoT) will rest.
A key strength of fiber optic is that it’s built to last decades, and accommodates an ever-growing demand for data. Even if the much anticipated 5G revolution is slower in coming than expected, current users of fiber optic will find it easier to plug into that revolution when it happens than those without it.
Already, there’s been some movement in the direction of setting up high-speed fiber-optic infrastructure on a city-wide level. In 2020, the government of Lagos began installing fiber optic cables across the city. So far, over 3,000km of fiber optic cables have been deployed, according to the government’s own reports.
As 5G gains traction, it is expected that the provision of fiber optic cables at the level of individual homes will gather pace.
A Fiber to the Home Solution That Works

Starlink Rolls Out V2 Satellites for Direct 5G Connectivity to Smartphones, Eyes Nigeria’s Rural Gaps

Starlink, owned by American billionaire Elon Musk, has unveiled plans for its next-generation Mobile V2 satellites, poised to beam full 5G cellular service directly to ordinary smartphones, bridging vast connectivity voids in Nigeria and beyond.

Starlink
The company, in an official website statement, described the V2 satellites as the pinnacle of satellite-to-mobile technology, powered by proprietary SpaceX silicon and phased-array antennas generating thousands of beams for 20 times the throughput of earlier models.
This leap enables unmodified phones to access high-speed internet for video calls, streaming, podcasts, and remote work, rivaling terrestrial 5G in most settings, Starlink said.
Seamless Integration with Local Networks
The satellites will partner with telecom firms, allowing handsets to toggle effortlessly between space-based and ground signals. In Nigeria, where rural blackspots persist, this could revolutionise access.
The Nigerian Communications Commission (NCC) backs such Direct-to-Device (D2D) innovations in its draft Spectrum Roadmap (2025-2030), hailing them for reaching riverine, border, and underserved communities without costly towers.
“D2D satellite services will extend voice and data to areas beyond mobile towers’ reach while bolstering resilience against fibre cuts, outages, and crises,” NCC stated.
African Telecom Giants Onboard
Deployment hinges on operator alliances. Airtel Africa inked a pact with SpaceX last year to roll out Direct-to-Cell across 14 countries, including Nigeria, filling terrestrial gaps.
MTN Group is advancing talks with Starlink and rivals to serve unnetworked regions, underscoring satellites’ role in affordable expansion.
As global telecoms chase ubiquitous coverage sans infrastructure overhauls, Starlink’s V2 could fast-track Nigeria’s digital economy targets.

Education Priorities to Help Young People Shape Africa’s Future

By: Juan Visser, Regional Director, Sub-Saharan Africa, International Education,
Today’s young people are navigating a world that is changing fast. From advances in artificial intelligence (AI) and technology to the impacts of climate change and global politics, they’re preparing not just to face uncertainty, but to shape what comes next.

Juan Visser, Regional Director, Sub-Saharan Africa, International Education
How effectively they do this will depend in part on their education, which has a crucial role in equipping students with the skills, knowledge and behaviours to thrive in the future.
Education is always evolving, but at this time of profound global change, we must keep asking ourselves if it is keeping pace. That’s what prompted the International Education group at Cambridge University Press & Assessment to undertake a large-scale research study with over 3,000 teachers and almost 4,000 students across 150 countries, including in Africa, to find out how they are experiencing education today.
Several priorities emerged in the Preparing Learners to Thrive in a Changing World study, highlighting a high degree of common thinking among students and teachers globally about where more action is needed in education to help students be ‘future-ready’.
1. Subject knowledge should be valued more in the AI era – not less
In an age where AI can deliver information within seconds, attitudes to the importance of subject knowledge are shifting.
When presented with a list of skills categories, knowledge and values, both teachers (81%) and students (73%) considered subject knowledge to be critical for students’ next step in education, but subject knowledge was the least selected option by both teachers and students when considering what is important for life beyond education.
This suggests that subject knowledge is often seen as a short-term asset for passing exams or progressing to higher education, rather than a lifelong asset. However, AI is not a shortcut to knowledge – and a solid foundation of subject knowledge is critical in helping students spot misinformation and use AI effectively.
To thrive, students need future-ready competencies such as adaptability and critical thinking – and here, subject knowledge and skills go hand in hand. We need to help students see that subject knowledge is something concrete they will draw on in the future, enabling them to assess information critically and make informed decisions.
2. Help students develop stronger self-management skills
Developing self-management skills – such as the ability to focus, prioritise tasks and regulate behaviour – emerged as a critical factor in helping students prepare for the future and adapt to changes in how we live and work. These skills can also solve some of the challenges created by digital technology, helping students to set boundaries for device use. While technology is embraced as a benefit to both teaching and learning, 70% of teachers said digital distraction and reduced attention span are challenges that technology creates in preparing students for the future. Students also voiced concerns about how their use of technology might affect them, with 66% worrying that they get distracted easily and 59% worrying about excessive screen time.
In Africa, the situation is complicated by inconsistent digital access. Many students are limited in opportunities to use technology to support learning, while those who have access, particularly via personal mobile devices, face the same struggle with distraction, such as access to social media, that students across the world are grappling with.
It’s clear that students would benefit from having more opportunities to practise self-management in school, not only to strengthen their focus but also to build resilience and help them deal with stress and anxiety. If students feel better able to manage themselves today, we are empowering them to manage new situations in the future.
3. Create safe and structured places to practise communication skills
Technology has transformed how we communicate with each other, yet the need to communicate effectively in person is not diminished. The research found that both teachers and students view communication skills, including social skills and empathy, as critical for future success.
However, the research also showed that concerns about getting communication wrong – which can be amplified in online spaces – are holding students back, with 61% of teachers saying fear of judgement is a challenge in helping students develop their interpersonal skills. Interviews with students also revealed that they may avoid disagreement due to fear of social repercussions, such as being the ‘lone voice’ or facing social judgement.
Schools can help students overcome these fears by creating a safe environment where they can develop their communication skills and build meaningful relationships.
Africa’s multilingual and diverse cultural contexts offer unique opportunities for developing communication skills.
Many African educational traditions emphasise oral communication, storytelling, and collective knowledge sharing, which support the development of communication skills in a context that students can relate to.
The tradition of active participation in African oral storytelling engages the audience, inviting them to ask questions, interact, and share their thoughts.
By incorporating African oral storytelling traditions into the curriculum, educators can create more inclusive, engaging and culturally relevant learning environments and help students develop key skills in listening, critical thinking and empathy.
4. Help students recognise when and how they are developing vital skills
With so much change in the world, it is perhaps not surprising that the research revealed students feel underprepared for the future. Only 48% of students feel prepared for their next step in education, and 45% for their future beyond it.
We also asked teachers to reflect on how well prepared they feel their students are for their futures. 67% feel students are well prepared for their next step in education, and 59% say students are well prepared for life after education.
These findings have profound implications for workforce development across Africa, where youth unemployment remains high despite growing economies.
If students don’t recognise their own readiness, they may not pursue opportunities they’re actually qualified for.
The underestimation may arise because students do not always see the skills they are developing alongside subject knowledge, nor do they understand how their school experiences can translate into future success.
To counter this, educators need to signpost students through their learning so they recognise the skills they are developing and understand how these skills may serve them in the future.
This will give them a stronger belief that they are prepared for the future and empower them to shape it.
Measuring impact: focusing on outcomes
With just under five years remaining to realise the 2030 education targets set by the United Nations, it is crucial that investments in education directly impact the UN Sustainable Development Goal 4.
Learning quality remains a major concern, and most countries are off track to meet education targets for access, completion and learning outcomes. In sub-Saharan Africa, upper-secondary school completion rates are hovering at 28,9%, far from the targets identified in 2015.
Many African education systems face resource constraints, making every investment count. The move from measuring inputs to focusing on outcomes is key to accelerating progress.
Initiatives like the HP Cambridge Partnership for Education EdTech Fellowship also provide a space for policymakers to strengthen the skills, knowledge and network needed to drive digital transformation in education systems.
The future of African education depends on embracing both the challenges and the unique opportunities presented by technology, evolving skill sets, and the continent’s rich cultural diversity.
Accelerating digital education is vital in Africa, but at the same time, educators must help students develop the skills and knowledge to use technology wisely.
By prioritising subject knowledge as well as skills development, strengthening self-management and communication skills, and helping young people to recognise all the ways in which they are prepared, educators can help empower them to thrive in a rapidly changing world.

First Batch of Nigerian Undergraduates Emerged in Airtel Africa Foundation Scholarships Programme

Airtel Africa Foundation has inducted the first Nigerian cohort of the Airtel Africa Tech Fellowship that offers fully paid scholarships for students pursuing undergraduate courses in science, technology, engineering and mathematics across the continent.

During a ceremony held at Airtel Nigeria headquarters in Lagos, Airtel Africa Foundation’s Chairman, Dr Segun Ogunsanya, alongside Airtel Nigeria’s CEO, Dinesh Balsingh, presented the full-ride scholarship awards to 70 students from universities across Nigeria.
The undergraduates studying technology courses, were drawn from the University of Lagos, Obafemi Awolowo University, the University of Benin, Tai Solarin University of Education, the University of Ilorin, Ahmadu Bello University, and the University of Nigeria.
Selected from thousands of applicants through an independently managed process, which took nearly six months, these fellows are beneficiaries of Airtel Africa Foundation’s continentwide financial aid programme, which covers tuition, laptop computers, living expenses, and essential learning resources. The Nigerian cohort joins a prestigious network of Airtel Africa Foundation fellows currently studying in Tanzania, the Democratic Republic of Congo (DRC), Uganda, and India.
In his address, Dr. Ogunsanya, emphasised the need for initiatives such as the Airtel Africa Foundation’s undergraduate tech scholarship for the future of the continent.
The Airtel Africa Foundation Chairman said, “True legacy is not measured by the awards we win or the volume of SIM cards we sell; it is measured by the lives we save, the people we feed, and the students we support when the line between success and failure is at its thinnest.
At the Airtel Africa Foundation, we believe that lifting people out of poverty is the ultimate benchmark of a great company. Today, we are writing that legacy by tilting the balance in favour of the brilliant but underserved, ensuring that the fourth industrial revolution, driven by AI and Data Science is built by African talent for the African continent.”
Dr Ogunsanya further revealed that this fellowship, executed through Airtel Nigeria, is designed to bridge the gap where funding, skills, and opportunity often fail to meet. In addition to the N500,000 yearly budget for the fellows’ four-year or five-year courses, each fellow would be integrated into a structured support system for academic guidance and career mentorship, intended to ultimately transition students from the classroom to the global tech workforce.
Addressing the students, Mr Balsingh emphasised that youth development is a strategic imperative for Airtel.
He said, “At Airtel Nigeria, we view youth development as essential nation-building. When young people succeed, innovation accelerates, and social stability improves. By connecting these brilliant scholars to knowledge, skills, and confidence, we are fulfilling our core mission to connect people to opportunity.
“To our recipients: you earned your place here through merit and discipline. You are now ambassadors of excellence, and we expect your leadership to be defined by your conduct as you help shape a more inclusive digital future for Nigeria.”
The initiative underscores a broader commitment to technology education, youth development, and Nigeria’s digital economy. By aligning academic excellence with industry requirements, Airtel Africa Foundation and Airtel Nigeria continue to demonstrate their dedication to skills as the new currency in a rapidly evolving global market.
