In an era where connectivity is the backbone of economies and everyday life, a young Nigerian innovator studying in the United Kingdom is developing a solution that could reshape how the world thinks about network reliability. Oluwafemi Clement Adeusi, a UK-based Nigerian and Network Security Analyst currently pursuing a master’s degree in Computer and Network Security at Staffordshire University, Stoke-On-Trent, has co-founded a start-up, Clefemad Tech, and is building what he calls the Clefa Modem—a technology designed to eliminate network instability, a problem that has long plagued Nigeria and other emerging economies.
In a recent virtual interview with TechBullion, Mr. Adeusi shared his journey, the origins of the idea, and the potential of the Clefa Modem to impact not just Africa, but the United Kingdom and the global digital economy.
Adeusi revealed that the concept for the Clefa Modem was born out of conversations with his friend, Nsikak Monday Akpan, back in 2019. “We talked extensively about the problems of fragmented networks in Nigeria and how unreliable connectivity was holding back entire sectors,” Adeusi recalled. “At that time, I felt it was just an idea. But two years later, in 2021, I decided it was time to take a step. Nsikak believed in the vision and agreed to assist in bringing it to fruition.”
The modem, which is still in its development stages, is designed to autonomously switch between multiple mobile networks in real time. Unlike traditional dual-SIM devices, the Clefa Modem uses software-defined intelligence to evaluate network signals and automatically connect to the strongest available option. This, Adeusi explained, could solve many of the longstanding connectivity frustrations Nigerians face daily.
For Adeusi, the project is not just technical, it is deeply personal. He recounted a terrifying experience during his undergraduate years in Nigeria, when poor network coverage almost cost him his life.
“On my way from School in Okitipupa, Nigeria, sometime in 2018, I was trapped in a vehicle hijacked by kidnappers. At the most critical moment, when I needed to reach out for help, my phone simply could not connect to any network,” he said solemnly. “The helplessness of that moment left an indelible mark on me. I knew then that unstable networks are not just an inconvenience; they are a threat to human safety and security.”
That incident continues to fuel his determination. “Clefa Modem is not just about faster internet. It is about ensuring no one is left stranded in dangerous circumstances because they cannot get a signal.”
Adeusi’s pursuit of a master’s degree at Staffordshire University has provided the academic reinforcement needed to refine his invention. His studies in advanced cryptography, network security, and cloud systems have allowed him to embed cutting-edge features into the modem design.
“The program has been a huge boost. I now understand better how to integrate cloud-based control, secure firmware updates, and low-energy efficiency into the Clefa Modem,” he explained. “The UK’s academic environment, with access to resources and mentorship, is giving me the tools to transform this idea into a commercially viable solution.”
By combining real-world problems from Nigeria with academic and technical expertise in the UK, Adeusi represents a new generation of innovators bridging continents.
“The Clefa Modem will be designed to unify fragmented networks into a seamless experience,” Adeusi emphasized. “If implemented at scale, it will reduce transaction failures, increase confidence in digital banking, and strengthen Nigeria’s reputation as a digital economy.”
The Bigger Picture: Nigeria, the UK, and Beyond
While Clefa Modem is first being developed for Nigeria, Adeusi believes the solution carries implications far beyond its borders. “In Nigeria, it will directly impact education, healthcare, banking, and security. For the UK, it opens the door to collaboration in manufacturing, software design, and export to emerging markets,” he explained. “Globally, this could become a model for solving connectivity problems in other countries facing similar issues, from parts of Africa to South Asia and Latin America.”
By improving reliability and reducing the cost of connectivity, Clefa Modem could also play a role in the global network security industry, particularly in securing mobile financial transactions and expanding broadband access in underserved regions.
Adeusi is confident that the invention, once finalized, will not only boost Nigeria’s digital economy but also establish the country as a serious player in global network innovation. “The UK has always supported groundbreaking ideas,” he noted. “I hope this will be one of those innovations that strengthens collaboration between our two nations.”
For many, unreliable mobile networks are an inconvenience. For Oluwafemi Adeusi, they are a problem worth solving on a global scale. His vision for the Clefa Modem goes beyond technology—it is about saving lives, empowering economies, and bridging divides.
As Nigeria battles with network instability and as the world increasingly relies on seamless connectivity, Adeusi’s invention may very well mark the beginning of a new chapter in the global network security industry.
