Broadband Satellites: Defining Efficiency and Flexibility to Drive 5G (Part 11)

By Andrew Aroh
USING KA-BAND BROADBAND SATELLITE FOR HIGH EFFICIENCIES AND FLEXIBILITY REQUIRED FOR 5G

- To obtain on-orbit flexibility as required for 5G there are certain stringent constraints that are required for commercial communications satellite payloads:
- Size
- Mass
- Cost
- Power consumption
- Reliability
- Technical risk
- In digital realization of the payload, we are looking at high-speed/low power characteristics while having radiation hardness.
- Microwave capabilities for SATCOM upper Microwave assemblies are advancing as designers have developed a number of integrated converters for frequencies up to 100GHz and more.
- Thus, the topology of a LEO-based Network has become very dynamic and uses fast-packet switching suitable for 5G
- For the Ka-band as well as the V-band systems, there are four main features required for high efficiency operations:
- Higher beam power
- Higher bandwidths
- Conduction cooling
- An enabling technology including AIS and ACM
- AIS (Automatic in route Selection) and ACM (Adaptive Code Modulation) enables a dynamic process through which the hub assess how much power the remote site needs to receive and send information in unfavourable weather conditions, enabling the highest efficiency of operations possible, all the time.
SPECIAL FEATURES OF ADVANCED COMMUNICATIONS SATELLITE PAYLOADS:
- Flexible multiple spot-beam combinations made possible by the large digital processor which provides.
- Switching and beam forming network with reconfigurable coverage
- Power flexibility between beams; a key technology for advanced Global Mobile Personal Communications (GMPCS); Broadcast and Military Mission.
- Multibeam active Antennas and onboard processing and switching make an ideal combination to provide the required full crossbeam connectivity and flexible traffic routing to drive 5G broadband LEO Satellites.
SUMMARY:
SATELLITE SWITCHING
Modern satellite systems frequently require multibeam operation to meet the link budget requirements. in these systems there is of course no guarantee that traffic originating in one uplink beam will be destined for the same downlink beam. The satellite transponder must provide interconnections between beams.
These connections must be selectable to allow for varying traffic patterns. In a TDMA system the time of arrival of an uplink signal at the satellite transponder determines its eventual destination; if the routing is defined on the satellite (i.e. satellite switched TDMA) the transponder must also perform a time-dependant beam switching.
ON-BOARD PROCESSING
The most advanced transponder types currently being designed may require additional forms of processing, for example, the so-called ‘switch-board in the sky’ systems move the central switching node of a communication system from the ground into space. In such a transponder, signals are demodulated prior to switching in complex time and space matrices.
When on-board processing is employed, it is possible to separately optimized up-and downlinks, by demodulating and then re-modulating in the transponder. Military transponders may require special forms of on-board processing to reject deliberate jamming by hostile forces.

New Investment Fund Targets Acceleration of Emerging Technology in Nigeria

The International Rescue Committee (IRC) has announced the formation of Airbel Ventures, a new humanitarian impact investing fund aimed at accelerating the introduction and scaling of breakthrough technologies in crisis-affected communities.

The fund will invest in companies whose ideas have the potential to change humanitarian response, including digital infrastructure for frontline health systems and climate-resilient agriculture.
The launch of Airbel Ventures follows a period of rapid innovation at the IRC, despite the humanitarian sector facing record funding cuts.
In the past year, the IRC’s Airbel Impact Lab has advanced more than twenty Artificial Intelligence (AI) and technology initiatives—from anticipatory action tools powered by climate and vulnerability data, to frontline service delivery using safe, orchestrated AI systems, to breakthrough diagnostic tools for emerging diseases.
Airbel Ventures’ first impact investment is in Signalytic, a company delivering solar-powered computing devices that ensure reliable electricity and connectivity for remote health facilities.
Following the investment, the IRC will pilot Signalytic’s technology with its Nigeria Health team, demonstrating the viability of next-generation digital infrastructure in humanitarian settings.
“We know breakthrough solutions already exist—what’s missing is the path to scale in humanitarian contexts,” said Dr. Jeannie Annan, Senior Vice President for Research & Innovation at the IRC and head of the Airbel Impact Lab.

MTN Nigeria Suffers 9,218 Fibre Cuts in 2025 as Vandalism, Theft Cripple Network

MTN Nigeria, the country’s largest telecommunications operator, recorded a historic surge in network disruptions in 2025, suffering 9,218 fibre cuts as of December 31, alongside 211 base station sites affected by theft and vandalism, incidents that disrupted mobile and data services relied upon daily by millions of Nigerians.

The data was revealed by Dr Karl Toriola, chief executive officer/managing director, MTN Nigeria via a social media post titled ‘MTN Nigeria 2025 Wrapped’.
The scale of the damage highlights the growing vulnerability of Nigeria’s telecommunications infrastructure, which has come under increasing pressure from road construction activities, cable theft and deliberate acts of vandalism.
MTN said 5,478 fibre cuts occurred within just the first seven months of 2025, with 760 incidents recorded in July alone, underscoring the intensity of the challenge.
Some of the incidents had wide-ranging consequences, knocking out connectivity across multiple states simultaneously and affecting voice calls, data services, digital payments and enterprise operations.
The company described the situation as a national infrastructure problem, rather than an isolated corporate issue, given the economy’s deep dependence on mobile networks.
“These gaps were shaped by real operational challenges such as fibre cuts, theft, and vandalism. Their impact is felt directly by customers and reflected in what they tell us,” Toriola,
The disruptions were reflected in customer feedback volumes, as MTN handled an unprecedented number of complaints during the year. The operator said it resolved 1,624,263 customer complaints in 2025, spanning call centres, social media platforms, emails and physical service centres nationwide.
Despite the setbacks, MTN pointed to signs of operational resilience. The company retained its ranking as Nigeria’s best network by Ookla, returned to profitability after a challenging period, declared an interim dividend, and expanded its subscriber base to over 85 million users by September 2025.
The figures show that while Nigeria’s telecom operators continue to invest heavily in network expansion and customer service, infrastructure sabotage remains a major drag on service quality and operating costs.
MTN acknowledged that performance improvements remain a work in progress. “We are not where we want to be yet. We see you. We hear you. We exist because of you. And we will get better,” Toriola said.
As the company enters its 25th year of operations in Nigeria, Toriola said MTN is doubling down on customer-centricity, treating every piece of feedback as a guide for improvement, while also stepping up engagement with government agencies.
The CEO renewed calls for stronger regulatory and legal protections for telecommunications infrastructure, urging policymakers to classify fibre cables, base stations and other critical assets as national infrastructure and criminalise vandalism to deter repeat attacks.

NCC Licences Six New ISPs to Challenge Telcos, Satellite Giants

Nigerian Communications Commission (NCC) has granted operating licences to six new Internet Service Providers (ISPs), effective January 1, 2026, raising the total number of authorised ISPs in the country to 231 from 225 recorded in December 2025.

NCC
The newly licensed firms are Intellvision Technologies Limited, Granet Technologies Limited, Fiber Sonic Limited, Dasol Solution Services Ltd, Boost ISP Limited, and Amazon Kuiper Nigeria Limited.
Five of these companies are headquartered in Lagos, while Granet Technologies Limited operates from Owerri in Imo State, highlighting the persistent concentration of broadband infrastructure in major commercial hubs like Lagos, Abuja, and Port Harcourt.
This development intensifies competition in Nigeria’s broadband market, which faces pressure from dominant mobile network operators such as MTN and Airtel, alongside rapid expansion by satellite providers like Starlink.
Traditional ISPs continue to grapple with shrinking customer bases, aggressive data pricing from telcos, and satellite disruptions, even as NCC data from Q2 2025 showed Spectranet, Starlink, and FibreOne controlling about 65 per cent of the 313,713 active ISP subscribers.
The inclusion of Amazon Kuiper Nigeria Limited marks a significant entry of global satellite broadband competition, building on Nigeria’s recent approvals for other low Earth orbit providers to enhance connectivity in underserved areas.
Industry analysts view the licences as a strategic push to improve internet quality amid rising demand for digital services, though geographic clustering underscores ongoing infrastructure challenges outside urban centres.
NCC’s move aligns with broader efforts to foster a competitive telecoms sector critical to Nigeria’s digital economy ambitions.
