Proliferation of antennas installed by Global System for Mobile communications (GSM) operators and microwave equipment by Code Division Multiple Access (CDMA) counterparts have been condemned by environmentalist not only because it distort environmental esthetics by also its health implications. This report looks at the health concerns of using mobile phone or living close to microwave equipment

The liberalization and revolution being experience in the telecommunications sector has been greeted with mixed feelings, while greater percentage of Nigerians are celebrating for breaking the jinxes of access to telephone service that was exclusively reserved for the rich, very few are expressing concerns over fear of radiation from microwave equipments installed by operators in their base stations as well as handsets.

Radiation is electromagnetic and it consists of waves of electric and magnetic energy moving together through space at the speed of light. We live in a world of radiation and we are exposed to both natural and man-made radiations, every second of our life, we are exposed to all forms of radiation such as ultraviolet light from the sun and radiowaves from radio and television broadcasts.

Dr. M. A. Aweda consultant medical physicist department of radiation biology and radiotherapy

College of Medicine of the University of Lagos, said there are two major effects of microwave radiation exposures that includes heating effect manifested in form of temperature increase and indirect effect which is when microwave interacts with water molecules to break it down to hydroxides, peroxides, superoxides, acqueous electrons, radicals which are very reactive chemically. "These products are toxic to living cells," he said.

These concerns have been wide spread that some state governments are attempting to regulate the deployment of base stations by telecom operators citing radiation effect as reason. A case in point is the running battle between Lagos State Infrastructure and Maintenance Regulatory Agency (Lasimra) and telecom operators.

Aside the taxation issues in the attempt by Lasimra to regulate deployment of base transmitting stations the agency has cited health implications on the people living close to Base Stations. Mr. Jeo Igbokwe, general manager, Lasimra had relied on a report on a research which he alleged is "still gathering momentum" in the Daily Mail London of 7th August last year implying that there is a casual connection between cancer patients and the fact that they live close to mobile mast installations and in order words that proximity to mobile installations such as masts can cause cancer. He went further that the Lasimra proposes shortly to set up a research team who will undertake research into the effects of telecoms Base Stations in Lagos State.

Perceived health concerns over proximity of humans to telecommunications installations / equipment and use of mobile phones are unfounded though it has remained an issue of concern to both the general public globally and the global telecoms industry.

Telecoms operators in Nigeria are registered and responsible members of the global Industry body, the GSM Association (GSMA), the International Telecommunications Union (ITU) and the Code Division Multiple Access (CDMA) Group. Thus, all Nigerian operators benefit from a huge body of research undertaken independently by the different industry bodies in conjunction with international bodies such as the World Health Organization (WHO) and the European Union (EU).

Past and ongoing research and studies have been conducted by the GSMA independently and in collaboration with WHO as well as by several other international organizations on possible effects on human health of proximity to telecommunications installations and equipment and use of mobile phones. These studies and research till date have failed to show any casual link between adverse health effects and telecommunications installations and equipment, and use of mobile phones.

In 2002 vodafone, a GSM operator in Britain had sought to install mobile telephone antennae in the towers of the Churches of St. Margaret, Hawes and Holy Trinity, Knaresborough, in the leads area of England. This action resulted in objections from residents within the vicinity of the Churches, primarily on the grounds of health risks from living close to the antennae. Vodafone petitioned the leads combined Court in the recent English cases of St. Margaret Hawes (No. 215 of 2002) and Holy Trinity Knaresborough (No. 233 of 2002).

The issue for determination before the Court was whether radiation from a telecommunications base station may affect the health of humans in the vicinities of such base stations and was resolved by determining the appropriate base station radiation emission threshold.

Vodafone’s case was based on the recommendation that the International Commission on Non Ionizing Radiation protection (ICNIRP) guidelines is the most widely accepted and should therefore be applicable. The objectors preferred the "Salzburg Resolution "(a different standard) which has lower thresholds than those of the ICNIRP guidelines.

Both vodafone and the objectors agreed that base station radiofrequency field are not strong enough to damage chemical bonds in the human body and are not cumulative over time. The parties also agreed that base stations radiations are less intense than those from a basic domestic appliance like the microwave and therefore cannot heat up (have a thermal effect on) a human body like such appliances could.

The Court held that research and scientific studies on human health and the relationship between exposure to radio frequency (RF) fields and different types of cancer, reproductive problems, congenital anomalies, epilepsy, headaches and suicide etcetera do not provide any conclusive evidence of adverse health effects. Further, the Court held that the balance of evidence to date suggests that exposures of RF radiation below the thresholds set by the UK National Radiation Protection Board (NRPB) and ICNIRP guidelines do not cause adverse health effects to humans.

However, all deployed telecoms equipment, installations, terminal equipment, mobile handsets and customer premise equipment sold by all Nigerian telecoms operations in their varied bundled promotions are type-approved by the telecommunications industry regulator, the Nigerian Communications Commission (NCC), in compliance with the electromagnetic field (EMF) thresholds set by the ICNIRP guidelines, the ITU, institute of Electrical and Electronic Engineers (IFEEE), amongst other industry standards setting bodies and as such do not pose any health threats.

At the Nigerian Communications Commission’s (NCC) monthly Telecoms Consumer Parliament held in Maiduguri on 2nd May 2006, Dr. Bashir Gwandu, executive commissioner, Licensing and Consumer Affairs, NCC, who represented Engr. Ernest Ndukwe, executive vice chairman of the commission in response to an enquiry by a learned Professor of the University of Maiduguri, made a clarification amongst others, to the effect the "there is no known conclusive Scientific evidence at present to indicate that radiation from telecommunication masts or handsets could cause such dangerous diseases as cancer among humans.

Mobile phone

The widespread use of mobile phones is a recent phenomenon. The use of cell phones and related technologies will continue to increase for the foreseeable future. Wireless devices such as cell phones, utilize radio waves (radiofrequency or electromagnetic fields) to transmit information.

Naturally, reports that suggest cell phones radiation may impact children’s health would raise questions in the minds of parents.

Dr. O.B. Eletu, managing director, MMSL said that the use of mobile phones by children is increasingly widespread and commencing at a younger age.

According to him pre-adolescent children can be expected to be (potentially) more at risk in the use of cell phone than are adults because the absorption of microwaves of the frequency used in cell phones is greater in an object about the size of a child’s head – the so-called head resonance – than in an adult’s. Thinner skull of a child allows more penetration of the radiation into the brain than in an adult.

The developing nervous system and associated brain-wave activity in a child are more vulnerable to the pulses of microwaves used in GSM than in a mature adult

The increased mitotic activity Eletu said in the cells of developing children makes them more susceptible to genetic damage.

"A child’s immune system is generally less robust than that of an adult, so that the child is less able to cope with any adverse health effect provoked by (chronic) exposure to such radiation," he said.

Dr. Eletu quoted chairman of the National Radiological Protection Board (NRPB) conclusion that there was no proven health risks associated with mobile phones but that children should minimize their use as a precaution. He added that May 2001 research in America which suggested that children’s brains absorbed 50-70 per cent more radiation from handsets than adults because their skulls were smaller.

More so, NCC had stated that research so far conducted have indicate that the use of mobile phones and proximity to telecommunications installations and equipment including base Stations, masts and antennae amongst others do not pose a risk to human health.

Nigeria, Others Stuck on WiFi 4 As World Adopts WiFi 6, WiFi 7

Published

Kindly share this post

Nigeria among other African countries are falling “dangerously” behind the rest of the world in the adoption of WiFi technologies, with nearly half of the continent’s internet users still relying on the ageing WiFi 4 standard, while developed markets increasingly transition to WiFi 6 and WiFi 7.

This is according to Ookla’s Global State of WiFi 2026 report, which analysed speed test data from Android devices worldwide and found a widening gap between Africa and leading global markets.

The firm used these devices to track the prevalence of different WiFi generations (WiFi 4 through WiFi 7), the spectrum bands being used (2.4GHz, 5GHz and 6GHz), and the installed base of customer premises equipment connected to those devices.

While WiFi 6 has become firmly established across much of the world, Africa remains heavily dependent on legacy wireless technologies that were introduced more than a decade ago, the report finds.

While countries such as South Korea, Japan, Singapore and the US are rapidly migrating toward WiFi 6 and WiFi 7, Africa remains largely anchored on WiFi 4.

South Africa remains one of the continent’s most advanced broadband markets, yet the country is struggling to gain traction with the latest WiFi technologies, states Ookla.

The report notes: “WiFi 4 – a standard finalised back in 2009 – still accounted for 48.8% of Africa’s WiFi samples in the first quarter, with WiFi 5 a fast riser at 34.4%, up from 19.9% four years earlier. WiFi 6 climbed from 1.6% to 16.8% over the same period, while WiFi 7 barely registered at 0.1%.”

Ookla’s findings show a divide between advanced broadband markets and developing regions when it comes to next-generation WiFi adoption.

By comparison, WiFi 6 has already captured 27% of the global market, up from just 6% in 2022.

“WiFi 7 has also begun establishing a foothold globally, accounting for nearly 2% of worldwide connections. Meanwhile, older WiFi 4 and WiFi 5 technologies continue to decline globally, falling to 34% and 39%, respectively,” says Ookla.

The strongest uptake of WiFi 6 and WiFi 7 is concentrated in technologically-mature markets such as the US, Canada, South Korea, Japan, Singapore and several Western European countries, where fibre broadband penetration is high and consumers upgrade smartphones, routers and home networking equipment more frequently, according to the report.

“These markets have also moved more aggressively to open up the 6GHz spectrum needed to support WiFi 6E and WiFi 7 services, helping accelerate adoption of newer wireless technologies.”

WiFi 7, the next evolution of the WiFi network protocol, promises to be a substantial upgrade over its predecessor – surpassing the speeds of Ethernet cables, and significantly improving connection reliability and latency over WiFi 6.

While SA’s market is still in the early stages of migration to next-generation wireless technologies, research firm 6Wresearch forecasts strong growth in SA’s WiFi 6 and WiFi 6E ecosystem over the next few years, driven by increasing demand for high-speed connectivity, fibre expansion and growing use of connected devices.

Legacy spectrum dependency

The report also highlights Africa’s continued dependence on older wireless spectrum bands.

The congested 2.4GHz band remains the dominant carrier of internet traffic across Africa, accounting for 52.4% of all WiFi samples during the first quarter of 2026.

Although this represents a significant improvement from the 76.4% share recorded in 2022, the continent still lags behind regions where users have largely migrated to higher-capacity spectrum, the report states.

The 5GHz band has expanded rapidly across Africa, growing from 23.6% of samples in 2022 to 47.6% in 2026. However, the newer 6GHz spectrum, which is critical to unlocking the full capabilities of WiFi 6E and WiFi 7, remains virtually non-existent across the continent.

“The congested 2.4GHz band remained the continent’s majority carrier at 52.4%, down from 76.4% in 2022, with the 5GHz band the chief beneficiary, rising from 23.6% to 47.6%.”

One of the starkest findings in the report is Africa’s complete absence from the global shift towards 6GHz WiFi.

Across the continent as a whole, the 6GHz band accounted for a flat 0.0% share of WiFi samples during the first quarter of 2026. South Africa was the only market to record any meaningful activity on the band, but even then usage reached just 0.2%.

The report states: “Just 0.2% of WiFi connections in South Africa ran over the 6GHz band in the first quarter of 2026. In a market where households keep routers and handsets for years, and where service providers have been slow to bundle 6GHz-capable customer premises equipment, an allocation on paper turns into real-world use only gradually.”

According to forecasts from Grand View Research, SA’s demand for WiFi 6 and WiFi 6E technologies is expected to accelerate sharply over the remainder of the decade, driven by enterprise digital transformation, smart-home deployments and increasing bandwidth requirements.

Device readiness

The Ookla report suggests that consumer devices are no longer the primary barrier to WiFi upgrades globally and in SA.

According to Ookla, 61.4% of Android devices sampled worldwide already support WiFi 6 or newer technologies. This indicates that many markets now possess the device ecosystem needed to support more advanced wireless networks.

“However, Africa faces a different reality. The continent’s slower replacement cycle for smartphones and routers, combined with high equipment costs, and slower deployment of advanced customer premises equipment, continues to delay migration to newer standards,” notes the report.

Other obstacles include regulatory and spectrum availability constraints, as a result of the full 6GHz spectrum still being debated by the Independent Communications Authority of South Africa and local telecoms operators.

Widening connectivity gap

The Ookla findings suggest Africa risks falling further behind as the rest of the world accelerates toward WiFi 6, WiFi 6E and WiFi 7.

While the continent has made notable progress by shifting traffic from the overcrowded 2.4GHz spectrum to the more capable 5GHz band, the overwhelming dominance of WiFi 4 and the near absence of 6GHz adoption highlight the scale of the challenge ahead.

While SA can function without widespread WiFi 6 and WiFi 7 adoption, there are significant economic, technological and competitiveness consequences if the country falls too far behind.

“These include reduced return on fibre investments, challenges supporting artificial intelligence and data-intensive applications, lower business competitiveness, persistent network congestion, slower smart city and internet of things development.”

Yuno, the global financial infrastructure platform, today announced a strategic partnership with Onafriq, the leading Pan-African payments network, to bring Africa’s most expansive payments infrastructure to merchants worldwide. Through this integration, Yuno’s clients gain instant access to Onafriq’s network spanning 43 African markets, nearly 1 billion mobile wallets, 500 million bank accounts, and 2,000 cross-border payment corridors, all through Yuno’s single, developer-friendly API.

Yuno Partners with Onafriq to Unlock Pan-African Payments for Global Merchants

As businesses increasingly look to Africa as a high-growth frontier, the partnership addresses one of the most persistent friction points in cross-border commerce: the complexity of connecting to fragmented, local payment rails across dozens of markets. By combining Yuno’s payment infrastructure capabilities with Onafriq’s deep-rooted African network, the two companies aim to dramatically reduce the time and technical overhead required for merchants to go live and scale across the continent.

Onafriq’s infrastructure supports the full payment lifecycle, from real-time disbursements and omnichannel collections to card issuance, treasury management, and stablecoin settlement, all underpinned by local regulatory licences and ISO 27001 and CMML3-certified security. For Yuno’s merchant base, this means the ability to pay out to mobile wallets, bank accounts, or cash pickup points, and accept payments across channels, without managing multiple integrations or compliance frameworks independently.

“Africa represents one of the most exciting growth opportunities in global commerce, and yet too many merchants are still locked out by payment infrastructure that wasn’t built for scale. Our partnership with Onafriq changes that,” said Juan Pablo Ortega, Co-Founder and CEO, Yuno. “By bringing their unmatched African network into our infrastructure layer, we’re giving our clients a single path to a continent-wide ecosystem with the reliability, compliance, and local depth they need to grow with confidence.”

The partnership is part of Yuno’s broader strategy to build a truly global platform that connects merchants to every meaningful payment method and network, regardless of geography. Following successful expansion in the Middle East, Europe, and Asia, Africa is a key pillar of Yuno’s next phase of growth.

For Onafriq, the integration with Yuno extends its reach to an entirely new segment of global merchants who now benefit from a streamlined entry point into African markets. The partnership reinforces Onafriq’s mission of making borders matter less, bringing together mobile money operators, banks, fintechs, and enterprises into one connected payment ecosystem.

“Africa’s payment landscape has never lacked ambition or momentum, what it needed is the right infrastructure that matches its pace. Our partnership with Yuno changes the equation for global merchants who want to be part of this growth story” said Dare Okoudjou, CEO, Onafriq. “Through a single connection, global merchants can reach consumers and businesses across Africa more seamlessly than ever before, while more people across the continent gain access to the digital economy on their own terms. For us, this is what making borders matter less looks like in practice.”

The integration is now live and available across Egypt, Ghana, Kenya, Nigeria, Cameroon, Cote D’Ivoire, and Uganda. Yuno’s clients can access Onafriq’s capabilities, including mobile money disbursements and collections, card issuance, and FX treasury services, directly from the Yuno dashboard with no additional contract or integration required.
