Technological Changes and Telecom Access Issues
One major challenge in telecommunications development in countries especially, those referred to as third world is providing telecommunications access to semi urban cities as well as rural areas.
To most operators in these countries, providing access to people living in those areas is not always a priority, basically because they are not commercially viable. Operators of telecommunications services are in the business to make profit and therefore could not afford to spend investors’ money on projects that does not have return on investment such as providing services to rural underserved areas.
In most developing economies, efforts at increasing access to people living in rural but underserved areas are pioneered by government through its agency saddled with the responsibility of regulating the sector. What the authorities does is to grant operators incentives that motivate them to expand their operations to those commercially none viable areas.
Over the years, telecommunications sector like any other sector in the economy are witnessing technological changes each time there is a new technology operators invest money in upgrading its equipment to the new technology.
Unfortunately, most of the new technologies instead of assisting operators in their effort to increase access to less developed areas through making the cost of providing services to such areas cheaper, concentrate more on service efficiency and network capacity to deliver several services.
More so, as these happens it increase cost of acquisition of hardware equipment required to access such service. For instance, when Global System for Mobile communications (GSM) operators upgraded their network from 2.5 Generation to third generation which allows subscribers to use voice, data and video simultaneously, the cost of handset that makes this possible were nowhere near average Nigerian.
Overview of technological changes
Although, Nigeria started late in the business of telecommunications, it has witness some technological upgrade by operators in the industry, all geared towards improvement of service delivery but none that seek to address access concerns to rural areas as well as making such service within the reach of a common man.
The first set of GSM operators that launched services after the industry was liberalized in 2001 used second generation technology to deliver services. Second generation 2G cellular telecom networks were commercially launched on the GSM standard in Finland in 1991. Three primary benefits of 2G networks over their predecessors were that phone conversations were digitally encrypted, 2G systems were significantly more efficient on the spectrum allowing for far greater mobile phone penetration levels; and 2G introduced data services for mobile, starting with SMS text messages.
After 2G was launched, the previous mobile telephone systems were retrospectively dubbed 1G. While radio signals on 1G networks are analog, and on 2G networks are digital, both systems use digital signaling to connect the radio towers (which listen to the handsets) to the rest of the telephone system.
According experts, digital systems were embraced by consumers for several reasons, which included, the lower powered radio signals require less battery power, so phones last much longer between charges, and batteries can be smaller.
The digital voice encoding allowed digital error checking which could increase sound quality by increasing dynamic range and lowering the noise floor.
The lower power emissions helped address health concerns. Going all-digital allowed for the introduction of digital data services, such as SMS and email. With analog systems it was possible to have two or more "cloned" handsets that had the same phone number.
A key digital advantage not often mentioned is that digital cellular calls are much harder to eavesdrop on by use of radio scanners. While the security algorithms used have proved not to be as secure as initially advertised, 2G phones are immensely more private than 1G phones, which have no protection against eavesdropping.
However, its shortcoming includes in less populous areas, the weaker digital signal may not be sufficient to reach a cell tower. This tends to be a particular problem on 2G systems deployed on higher frequencies, but is mostly not a problem on 2G systems deployed on lower frequencies. National regulations differ greatly among countries which dictate where 2G can be deployed.
Analog has a smooth decay curve, digital a jagged steppy one. This can be both an advantage and a disadvantage. Under good conditions, digital will sound better. Under slightly worse conditions, analog will experience static, while digital has occasional dropouts. As conditions worsen, though, digital will start to completely fail, by dropping calls or being unintelligible, while analog slowly gets worse, generally holding a call longer and allowing at least a few words to get through.
While digital calls tend to be free of static and background noise, the lossy compression used by the codecs takes a toll; the range of sound that they convey is reduced. You’ll hear less of the tonality of someone’s voice talking on a digital cellphone, but you will hear it more clearly.
2.5G is a stepping stone between 2G and 3G cellular wireless technologies. The term "second and a half generation" is used to describe 2G-systems that have implemented a packet switched domain in addition to the circuit switched domain. It does not necessarily provide faster services because bundling of timeslots is used for circuit switched data services (HSCSD) as well.
International Mobile Telecommunications-2000 (IMT-2000), better known as 3G or 3rd Generation, is a family of standards for mobile telecommunications defined by the International Telecommunication Union, which includes GSM EDGE, UMTS, and CDMA2000 as well as Dect and WiMax. Services include wide-area wireless voice telephone, video calls, and wireless data, all in a mobile environment. Compared to 2G and 2.5G services, 3G allows simultaneous use of speech and data services and higher data rates (up to 14.0 Mbit/s on the downlink and 5.8 Mbit/s on the uplink with HSPA+). Thus, 3G networks enable network operators to offer users a wider range of more advanced services while achieving greater network capacity through improved spectral efficiency.
4G refers to the fourth generation of cellular wireless standards. It is a successor to 3G and 2G standards, with the aim to provide a wide range of data rates up to ultra-broadband (gigabit-speed) Internet access to mobile as well as stationary users. Although 4G is a broad term that has had several different and more vague definitions, this article uses 4G to refer to IMT Advanced (International Mobile Telecommunications Advanced), as defined by ITU-R.
A 4G cellular system must have target peak data rates of up to approximately 100 Mbit/s for high mobility such as mobile access and up to approximately 1 Gbit/s for low mobility such as nomadic/local wireless access, according to the ITU requirements. Scalable bandwidths up to at least 40 MHz should be provided. A 4G system is expected to provide a comprehensive and secure all-IP based solution where facilities such as IP telephony, ultra-broadband Internet access, gaming services and HDTV streamed multimedia may be provided to users.
LTE Advanced (Long-term-evolution Advanced) is a candidate for IMT-Advanced standard, formally submitted by the 3GPP organization to ITU-T in the fall 2009, and expected to be released in 2011. The target of 3GPP LTE Advanced is to reach and surpass the ITU requirements. LTE Advanced should be compatible with first release LTE equipment, and should share frequency bands with first release LTE.
The Mobile WiMAX (IEEE 802.16e-2005) mobile wireless broadband access (MWBA) standard is sometimes branded 4G, and offers peak data rates of 128 Mbit/s downlink and 56 Mbit/s uplink over 20 MHz wide channels. The IEEE 802.16m evolution of 802.16e is under development, with the objective to fulfill the IMT-Advanced criteria of 1000 Mbit/s for stationary reception and 100 Mbit/s for mobile reception.
UMB (Ultra Mobile Broadband) was the brand name for a discontinued 4G project within the 3GPP2 standardization group to improve the CDMA2000 mobile phone standard for next generation applications and requirements.
Engr. Bayo Banjo, general manager, Disc Communications, said that technological advancement in telecommunications are products of research carried out by especially equipment vendors, and that these vendors invest in research and development with the idea of making profits from the sale of products of such research.
He added that the guiding principle is demand of the product which often time has a global outlook and such would not want to invest in product whose demand is low. He explained that why technological advancements in telecommunications industry are not looking at a way of making equipments for network roll out that will be cheaper and may not require some basic infrastructure is because such equipment vendors are using their home countries which has such infrastructure as basis for producing any product.
He regretted the situation in the country where 60 per cent of telecommunications activities are centred around cities like Lagos, Abuja and Port Harcourt because government has failed in its effort to provide adequate infrastructure such as electric to the citizens there by forcing operators to concentrate in the cities where residents can provide generators to use their telecommunications equipment required to enjoy telecommunications services.
He noted that presently, telecommunications equipments for network roll out are getting cheaper as a result of economic meltdown and emergence of Asian vendors such as Huawei.

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

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

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.

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.
