Technology has become so familiar that we barely think about what makes it work.
We make video calls, stream movies, use AI, send files across continents and access information within seconds.
Behind these simple actions is a vast system of radio frequencies, microchips, fibre optic cables, data centres and communication networks.
On Saturday, April 25, 2026, Engr Uzodimma Odimuko, Class of 2000, revealed this technological system to DIAA members through his presentation “Beyond the Handset: Scaling Networks to Connect Machines and Intelligence“.
Here are five lessons from the presentation.
1. Successful Companies Continue to Adapt
Nokia is remembered by many people as one of the companies that dominated the mobile phone industry.
Uzo explained that Nokia had operated in industries such as paper and rubber before becoming one of the world’s major telecommunications companies.
The ability to change is important.
A company can become very successful at one technology and still struggle when the market changes. Nokia experienced this when smartphones transformed the mobile phone industry.
The company lost its dominant position in handsets, but Nokia did not disappear. It shifted its attention to telecommunications infrastructure, networking equipment and cloud technology.
Past success gives us experience and resources. It does not guarantee future relevance.
Markets change. Customer behaviour changes. Technology changes.
We have to keep watching what is happening around us and develop the ability to respond before change makes our existing skills or business models less valuable.
2. The Technology We Use Every Day Depends on Enormous Infrastructure
A smartphone appears simple when we hold it in our hands.
But the system behind it is not simple.
Uzo explained how telecommunications begins with the electromagnetic spectrum. Governments regulate this spectrum and allocate frequencies to telecommunications companies and other users.
Those frequencies allow information to travel wirelessly.
Then there are microchips.
Modern chips contain billions of tiny electronic switches known as transistors. These transistors form the logic gates that allow computers and other electronic devices to process information.
The cloud is sometimes described as though information floats around the internet. Uzo explained that the cloud consists of physical infrastructure: huge data centres containing servers, storage equipment and networking systems.
These data centres are connected across countries and continents through high capacity networks, including submarine fibre optic cables running along the seabed.
When you send a WhatsApp message from Lagos to someone in London or New York, several layers of infrastructure are involved.
What appears effortless to you depends on decades of scientific research, massive investments and technological equipment spread across continents.
3. Microchips Have Become Part of Global Politics
Advanced computer chips contain billions of microscopic transistors.
Uzo discussed ASML, the Dutch company that produces the extreme ultraviolet lithography systems used in manufacturing the world’s most advanced semiconductors.
That technology has become important because advanced chips power AI systems, telecommunications infrastructure, military technology, data centres and many other critical industries.
Countries have started treating access to semiconductor technology as an issue of national security.
The United States and some of its allies have restricted China’s access to certain advanced chipmaking technologies as competition between the two countries expands into artificial intelligence.
This tells us something about the modern economy.
Resources that determine national power are changing.
Oil, minerals, factories and military equipment are still important. Computing power, semiconductors, AI, telecommunications infrastructure and data are increasingly important too.
Technology is now shaping international politics as much as international politics is shaping technology.
4. The Next Communication Revolution Will Connect Machines
3G made mobile internet possible.
4G helped services such as YouTube, Instagram, Spotify and other data intensive applications become part of everyday life.
5G is taking communications in another direction.
Mining companies can operate enormous autonomous trucks. Ports can automate parts of their operations. Warehouses can use autonomous mobile robots to move goods.
These machines need to communicate quickly with other machines and computer systems.
The future of telecommunications extends far beyond people making calls or browsing the internet.
Factories, vehicles, robots, sensors, ports, mines and other infrastructure will increasingly communicate through networks.
The handset may eventually become only one small part of a much larger connected world.
5. Young People Need Depth, Curiosity and Strong Foundations
Uzo mentioned subjects like data science, networking, cybersecurity and DevOps as areas young Dorityans should study if they want careers in the global technology industry.
He advised young people to choose an area of study and build deep knowledge in that area instead of trying to pursue everything at the same time.
New courses, certifications, programming languages and career opportunities appear every week.
Trying to learn everything can produce shallow knowledge of many subjects.
Curiosity helps us explore. Focus allows us to develop expertise.
Much of the science behind Uzo’s presentation could be traced back to concepts taught in secondary school physics.
Students may sometimes wonder why they have to learn subjects that appear disconnected from their future careers.
Years later, those same concepts may become the foundation for understanding telecommunications, engineering, computing or another profession.
