By Andrew Aroh

  • 5G is a technology that will push the boundaries of throughput and capacity further beyond that of 4G to enable newer types of applications and services in the domains of: Health, Transport (Land, Air and Sea), Entertainment, M2M, Security, etc.
  • 5G will lead to a huge shift towards a landscape dominated by wireless connectivity.
  • 5G is accompanied with deployment of Architectures (Fiber +Terrestrials wireless + Satellite leveraging Network Functions Virtualization (NFV) and Software Defined Networking (SDN) both at the core and edge of the Network. They will provide: increased computing power, scalability, reduced operating costs and business models to enable differentiation
  • 5G will enable instantaneous connectivity to billions of devices, the Internet-of-things (IoTs) and a truly connected world: smart cities, smart homes and smart schools, etc.
  • The satellite transport conduit will be integrated into the overall available communication map
  • Service providers will need to provide seamless connectivity between terrestrial and satellite
  • Traffic will be dynamically steered to the best transport options available (terrestrial/Satellite according to bandwidth, latency, network conditions and other application-specific requirements)
  • The interworking between terrestrial and satellite is now well recognized and promoted in the 3GPP standards.
  • Management of the NFV infrastructure will be performed through a management and orchestrator (MANO) Framework
  • This architecture allows easy integration of multiple applications
  • A virtual evolved packet core (vEPC) application would extend local call switching possibility.

A Mobile (Multi access) edge computing (MEC) platform could host different application like caching and multicast which can help reduce latency and improve qualify of experience (QoE) for the user.

  • Full integration within the virtualized architecture will apply to satellite as well, beginning with the network core and then expanding to the edge.
  • Satellite optimized Quality of service (QoS) and Operational Expense (OPEX) advantage will also remain key as the landscape becomes even more competitive.
  • New opportunities for extending satellites services in urban and rural areas will emerge for:
  • Covering white zones and ensuring a seamless connectivity plan
  • Emergency services
  • Broadcast/multicast and network offload schemes
  • Aero and Maritime mobility
  • Connected cars (software download)
  • Mobile backhaul
  • Newer low Earth Orbit (LEO) and Medium Earth Orbit (MEO) constellations will further expand the reach of satellite communications
  • Oneweb has launched its first batch of satellites that will provide internet access (using mobile/multiple access) Edge computing (MEC) platform to rural regions around the world.
  • Oneweb plan is to build a large network of satellites that will be hung in low earth orbit and beam down broadband internet to underserved areas. The company planned to put up 650 satellites by 2020, with a plan to expand to 900 as it expands its coverage. The network will be built over the course of 21 launches to deploy the satellites
  • Space-X is also building a global, broadband LEO constellation of satellites to provide broadband internet access, Interactive multimedia and high-quality voice, operating in the high Frequency ka-band of the radio spectrum.
  • Boeing is set to create a new Non-Geosynchronous (NGSO) Satellite constellation for broadband services using V-band for low-latency, very high data rate broadband across the United Stats and the world.

Between rising commercial demand and government-driven universal broadband service obligations, the company expects satellite could play a major role.

  • It really comes down to the insatiable demand for bandwidth that we are seeing in the market place. The amount of bits being required by all of us is growing on the order of 20 something percent a year, and in order to meet that demand there are certain areas where satellite has advantages over terrestrial approaches. Customers lack choice in the broadband provider options, especially in rural areas, meaning there is room for more satellite broadband players to compete.
  • In the spectrum front, the constellation could downlink information in the 37.5 to 40.0 GHz band on a shared access basis with the proposed Upper Microwave Flexible Use (UMFU) Service.

THE HIGH FREQUENCIES OF THE EM SPECTRUM

DESCRIPTIONFREQUENCYWAVELENGTH
HF3-30MHz100-10m
VHF50-100MHz6-3m
UHF400-1000MHz75-30cm
Microwave3×109 – 1011Hz10cm-3mm
Millimeter waves 1011-1012Hz3mm-0.3mm
Infra-red1012-6×1014Hz0.3m-0.5um
Light6×1014-8×1014Hz0.5um-0.4um
Ultraviolet8×1014-1017Hz0.4um-10-9m
X-Rays1017-1019Hz10-9m-10-13m
Gamman Rays>1019Hz>10-13m

 

Increased spectrum for 5G will provide:

  • Continuous connection
  • Greater capacity
  • More data
  • More users
  • Faster speeds
  • Faster Response Time (Lower-Latency) for connections
  • The increased spectrum in the mmW band will provide localized coverage as they only operate overshot distances
  • Future 5G deployments may use mmW frequencies in bands up to 86GHz
  • On the technology side, Boeing would want to taking its digital pay load technology from it GEO System and putting it into a Small Satellite Form Factor (SSFF). This is because there is a definite advantage in applying them to V-band NGSO System. The digital payload is SCALABLE and can be sized up or down as needed
  • The new trend is to shorten development cycles of satellites and make sure the next generation capabilities are brought up quickly and not have these long development cycles that have been in the past. The process involves continuous miniaturization in order to fit more transistors on integrated circuits (ICs), or essentially bringing Moore’s law to bear in space. This could dovetail well with the companies LEO ambitions, as satellites in this orbit typically have shorter life span and therefore require less radiation hardening compared to 15-year geostationary satellites.  

Features of SATCOM SOLUTIONS FOR 5G

  • Cost Effective
  • Plug and play
  • Enabling Mobile Operators and Network Vendors to accelerate 5G deployment across all geographies and multiple use cases
  • Creating new and growing market opportunities for SATCOM Industry Stakeholders
  • Integrating Satellite Links with heavy emphasis on standardization to allow trusted operation and to Facilitate industry adoption
  • Focus in on eMBB(enhanced Mobile Broadband) to fixed and Mobile Networks, including support for orchestration and slicing, with the satellite links providing backhaul connectivity either alone or in parallel (Multilink) connectivity with terrestrial links.
  • Platform which enables high efficiency, high performance, Virtualization and Multiservice capability parameter for 5G.
  • Consider the Successful Demonstration of 5G Connectivity over a LEO Satellite, Powered by Gilat using Telesats phase 1 LEO
  • At EuCNC 2019, Sat5G conducted six demonstrations showcasing 5G use case over satellite: Video Streaming, Content Caching, Airline Connectivity, 5G NR over satellite, Backhaul applications-1, Backhaul applications-2
  • In General, Testing campaign confirms LEO provides superior fiber-like performance for high end satellite services.
  • The ability to demonstrate Fiber-Like performance via satellite across a number of applications that perform poorly on GEO satellite backhaul is a testament to the capabilities of LEO network for 5G.
  • With its high-throughput links, ultra-low latency, and disruptive economics, LEO constellations offers an unparalleled value proposition to expand the reach of 4G and 5G networks.

Test Scenarios Included:

  • High definition Video steaming without interruption
  • Video conference with teams demonstrating consistent and voice transmission with user experience matching terrestrial and cellular connections
  • Remote desktop connection to seamlessly manage a remote computer
  • VPN connection without any delay or outages
  • FTP encrypted file transfers of 2GB in both directions
  • IPsec tuned encryption with no reduction in the performance of the link.

As satellite professionals plan, design and build offerings to provide best-in-class connectivity for 5G customers, we are eager to explore how cutting edge technologies like new LEO constellations can integrate with global connectivity infrastructure across every application to deliver an outstanding performance, with significant improvement over what we can achieve via GEO satellites today.

Therefore, to get super-high, multi-gigabit speeds, carriers are first turning to newer, much higher frequencies, known as millimeter-wave (mmW).

Airtel Africa Extends $100M Share Buyback Plan

Published

Kindly share this post

Airtel Africa has extended its $100 million share buyback programme, first launched in December 2024, in partnership with Barclays Capital Securities Limited. The scheme, aimed at improving shareholder returns, has so far returned $34.7 million through the repurchase of 14.2 million shares, with $20.3 million still to be acquired.

The initiative, now running until March 2026, follows the completion of an initial $50 million phase in April 2025 and currently includes a $55 million tranche.

The telecommunications group, listed on the Nigerian Exchange (NGX), is operating within regulations that restrict share buybacks to 15 percent of issued shares over two years. All repurchased shares will be cancelled, reducing the company’s share capital and potentially increasing earnings per share (EPS).

The buyback follows a strong performance in the first quarter of 2025, when Airtel Africa reported a 16-fold increase in EPS to 3.4 cents, supported by higher operating profits and lower foreign exchange losses. The company also raised capital expenditure by 27 percent, investing $737 million in 2024 to expand infrastructure and secure spectrum across its markets.

The extension of the scheme, according to Airtel Africa, also reflects its intention to provide consistent shareholder value while maintaining investment in its network. The partnership with Barclays ensures compliance with regulations during closed trading periods and seeks to limit market disruption.

Airtel Africa has in recent years considered a separate listing of its mobile money business but postponed the initial public offering in 2025, choosing instead to direct capital into shareholder-focused measures such as the buyback.

Industry observers point out that buybacks may improve financial ratios by reducing outstanding shares, but they can also indicate fewer reinvestment options. Airtel Africa has argued that its programme complements long-term growth priorities, pointing to a 29.5 percent increase in mobile money revenue and a 24 percent rise in its customer base.

The company continues to weigh shareholder rewards alongside reinvestment, citing foreign exchange volatility and other economic pressures in its largest market, Nigeria.

Stakeholders Chart Strategic Path for MVNOs in Nigeria

Published

Kindly share this post

A decisive call for collaboration, strategic market positioning, and patient capital has been issued by key players in Nigeria’s telecommunications sector to unlock the dormant potential of Mobile Virtual Network Operators (MVNOs).

The resolution emerged from the sixth edition of the Telecoms Sector Sustainability Forum (TSSF) organised by Business Remarks at Ikeja, Lagos State, where stakeholders convened under the theme: Unlocking Nigeria’s MVNO Potential: Status, Trends, Investment, and Future Prospects.

The forum, which brought together major mobile network operators (MNOs), the Nigerian Communications Commission (NCC), and licensed MVNOs, served as a candid platform to diagnose the critical challenges stifling the growth of the MVNO sub-sector. The forum stressed that the sustainability of MVNOs in Nigeria is a collective responsibility. It called for unwavering collaboration between MNOs, the NCC, and the MVNOs to replicate the success stories seen in other nations, ultimately fostering a more diverse, competitive, and inclusive telecommunications market for all Nigerians.

In his keynote address, the Executive Vice Chairman of the Nigerian Communication Commission, NCC, Dr. Aminu Maida said the entrance of MVNOs is expected to provide competitive niche offerings as well as enhance digital communications ecosystem in Nigeria for the benefit of the subscribers and the Nigerian economy.

Ably represented by the Director of Licensing and Authorisation, Mr Usman Mamman, NCC noted that there are now over 1000 MVNOs globally, with more than 500 operating in Europe alone and 46 MVNO Licenses were issued in Nigeria by the regulator in the year 2023.

Addressing stakeholders, Maida stated that the Commission is not oblivion to the challenges faced by MVNOs in Nigeria, particularly in relation to commercial negotiations. He therefore pledged that NCC is working assiduously with Mobile Network Operators (MNOs) to improve network capacity.

Furthermore, NCC’s EVC encouraged MNOs to partner with MVNOs to target new verticals, drive margin growth as well as to monetize spare capacity, while urging MVNOs players to recognise the viability of the Nigerian market, invest boldly, and position themselves to reap the long-term benefits of their investments.

In his speech, the President of the Association of Telecommunications Companies of Nigeria (ATCON), Mr Tony Izuagbe Emoekpere, dissuaded MVNO Licensees from blindly adopting foreign MVNOs model for Nigerian local market and consumers. He urged players to conduct diligent market analysis and focus on service differentiation through specialized offerings. “MVNOs need to carve a unique niche specially designed for the Nigerian market,” Emoekpere said.

Speaking on this, the co-founder and executive director, Infratel Africa, Dr Tola Yusuf, stressed that MVNOs in Nigeria’s market must adopt a more strategic approach to succeed in rural and underserved areas. Categorically noting that there are immense potential in connecting these rural communities, Yusuf argued that MVNOs often focus on urban, high-density areas like Lagos, neglecting the vast majority of the population, estimated at over 25 million people who remain completely unconnected.

“The true winners in the MVNO space will be those who develop a clear strategy to serve these markets, even if it requires significant logistical effort, such as using horses or boats to reach remote communities,” he said. He also suggested that the current market might see future mergers and acquisitions, with some license holders potentially selling their licenses as they fail to compete effectively.

Citing examples of banks with MVNOs licenses in other climes, NCC’s Director of Licensing and Authorisation, Mr Usman Mamman during the panel session draws attention to how financial institutions have successfully entered the telecom space by understanding its customers’ needs and tailoring holistic lifestyle services accordingly.

While addressing the need to focus on providing niche services to specific customer groups, Mamman noted that unlike large mobile network operators, MVNOs are expected to be digital-first and flexible, which enables them to be innovative and quickly capitalize on underserved market segments.

On his part, the Director USK Mobile, Dr Chidi Ajuzie, called attention to the capacity constraints by the host MNOs and the revenue- sharing model that can limit profitability. Ajuzie

According to him, “Tier 5 MVNOs are expected to build their own core infrastructure and billing systems (BSS/OSS), but they still rely on the MNO’s radio access network. This creates a bottleneck. Even if a Tier 5 MVNO has excellent billing systems, it can’t offer unlimited data or guaranteed high speeds if the MNO’s network is already at capacity,” he stated.

Ajuzie, however, said some higher-tier are now looking for innovative ways to go beyond the constraint by securing acquiring additional licenses, such as Internet Service Provider (ISP) or Public Licence (PL) licenses.

He also emphasized the
need for a significant expansion of the existing infrastructure, particularly by MVNOs who are now integrating their own fixed infrastructure, such as fiber networks. This expansion, he says, is the only way to “expand the pipe” and create a truly competitive and viable market for all players.

Also speaking ipNX Director of Startegic Business Initiative, Mr Olusola Teniola argued that the nation’s 40,000 telecom towers are grossly insufficient for a population of over 200 million, especially when compared to the United Kingdom’s 75,000 towers for a much smaller population. He stated that unlike developed nations where public funds initially built a robust telecom backbone, Nigeria’s infrastructure was financed by a few dominant mobile network operators (MNOs) who have invested billions.

Teniola posited that the lack of widespread infrastructure, particularly outside major cities like Lagos, Abuja, and Port Harcourt, presents a major challenge for new MVNOs, which were intended to serve the millions of unconnected Nigerians, particularly in rural areas. He also warned that without substantial new investment to expand the network, the MVNO business model will struggle to succeed, with only those that can survive a long-term, 7-to-10-year investment cycle likely to see a return on their capital.

In her welcome address, the Convener who also doubles as the Managing Editor of Business Remarks, Bukola Olanrewaju, said the Nigerian telecom market is growing at an incredible pace and the level of success recorded in each country with MVNOs is largely dependent on the regulatory enforcement and interventions, wholesale agreement, spectrum access, and on how effectively MVNOs players can navigate these hurdles.

“To succeed, Nigeria must collectively build an ecosystem that is both competitive and sustainable,” Olanrewaju remarked as she brought into focus MVNOs operations in South Africa, Thailand and Argentina.

The forum, TSSF 6.0, stressed that the sustainability of MVNOs in Nigeria is a collective responsibility. It called for unwavering collaboration between MNOs, the NCC, and the MVNOs themselves to replicate the success stories seen in other nations, ultimately fostering a more diverse, competitive, and inclusive telecommunications market for all Nigerians.

Nigeria has recorded an 84 Percent  decline in spam SMS after Airtel Africa deployed its Artificial Intelligence-powered spam detection tool, Spam Alert.

Airtel AI Blocks 84 Percent of Spam SMS in Nigeria

According to Airtel, the free service has flagged over 205 million fraudulent and unsolicited messages across 13 African markets within six months.

Nigeria registered the sharpest decline, while Kenya recorded the highest flagged spam volume with 68 million messages, followed by Tanzania with 47 million and Zambia with 33 million.

Spam Alert prefixes suspicious SMS with “SPAM Alert,” providing users with real-time protection against phishing scams and nuisance texts without requiring extra applications.

Sunil Taldar, CEO, Airtel Africa, said the solution demonstrates the company’s commitment to tackling digital fraud as smartphone penetration expands across Africa.

Currently active in 13 of Airtel’s 14 markets, including Nigeria, Uganda, Zambia, and Tanzania, the service has cut overall spam SMS by 12% across the continent. Seychelles will join soon, Airtel confirmed.

In Nigeria, Airtel reported that between March 13 and May 20, 2025, the system intercepted more than 9.6 million suspicious messages, of which over 9.1 million originated from off-network sources. T

he AI-powered system scans all SMS in real-time using 250 parameters, including sender identity, link structure, and regional anomalies, processing each message in under two milliseconds without storing content.

The Nigerian Communications Commission (NCC) welcomed the innovation.

Dr. Aminu Maida, executive vice chairman, said the initiative strengthens consumer protection at a time when spam and fraud are growing more sophisticated. He stressed the need for more collaboration between operators and regulators to reduce digital risks.

The NCC’s 2023 Industry Risk Report had ranked phishing and bulk unsolicited messaging among the top threats facing subscribers, especially in rural areas and among first-time smartphone users.

Airtel’s initiative is expected to ease these concerns by reinforcing trust in mobile communications.
