SATCOM: Creating End-to-End Efficiency for IP Trunking and IP Backbone Networks for 5G

By Andrew Aroh
- Efficiency and more throughput are at the core of emerging technologies for IP at the core of emerging technologies for IP Trunking and IP Backbone networks and applications to drive 5G.

- The latest technology is based on DVB-S2 and S2 Extensions standards and combines a set of innovative technologies in order to fully optimize the Trunking and Backbone Links. These technologies are:
- Adaptive coding and modulation (ACM)
- Cross-layer Optimization
- Bandwidth cancellation
- Clean Channel Technology
- Automated Uplink Power Control (AUPC)
- Wideband in GBs
The Dedicated technologies enhance the data throughput up to record breaking speeds in a large set of IP point-to-point or point or point-to-Multipoint networks.
- Adaptive Coding and Modulation (ACM)
- The tranking business is a highly competitive market with continuous pressure on pricing and profitability.
- The implementation of ACM translates directly into new business opportunities for ISPs, satellite service Operators and Satellite Operators.
- ACM increases the customer base within the same bandwidth. At the same time it introduces ways to reduce OPEX costs and increase the profitability of one’s business. Resulting in a quick Return-on Investment.
- ACM combines DVB-S2 and S2 Extensions with different technologies to get as much data through the same satellite bandwidth as possible.
- ACM will auto-adaptively set modulation parameters to the optimal point and overcomes distortion, noise and variation in the satellite link.
- Through ACM the data rates between uplink and remote sites (for both point-to-point and point-to-mattip networks) can be doubled in the same bandwidth without the need to acquire extra satellite capacity. As such a quick Return-on-Investment can be achieved in a matter of months.
- Optimal Service Availability through ACM
- Communication lines over satellite need to be available at all time to exchange critical information and to keep customer satisfaction at a high level.
- However, fading conditions could seriously disturb the satellite transmission and lead to temporary link losses.
- Fading conditions could be due to different circumstances:
- The choice of satellite/frequency and (Geo, Leo, Meo/C-,X-,Ku-,Ka-,V-band)
- Environmental Conditions (rain, dust, etc.)
- Interference (between two adjacent Satellites)
- Due to the auto-adaptive technology incorporated inside ACM, these fading conditions will no longer interrupt the transmission between the hub and remote nor result in the loss of data.
- In fading conditions, ACM will switch to a more robust modulation and provide optimal availability.
As soon as fading conditions are over, ACM technology automatically switches back to maximum efficiency,
- Moreover, Service Priorities (e.g video, data, voice) and Quality-of-service policies can be auto-adapted on-the-fly depending on the bandwidth availability through cross-layer optimization technology.
- Network Traffic Optimization
- Network congestion reduces the customer experience and the overall throughput over the communications link
- In order to Enhance Speed and Save on bandwidth, Service Providers can easily add Network Optimization to their Trunking Links.
- Network Optimization Consists of the Latest TCP/IP Acceleration and Compression Technologies which increases the efficiency of the satellite link on top of technologies such as ACM.
- Network Optimization is available as option in the Hubs or can added as separate equipment or software.
- Network Optimization technology offers up to 35% bandwidth reduction for typical applications such as file download, web surfing and content streaming.
- The reduction of traffic in both Volume and Number of packets is up to 20% in the forward and up to 90% in the return.
- Network Optimization technology improves customer Experience and results in important bandwidth gains.
- Bandwidth Cancellation:
- Uses Bandwidth Canceller
- Return traffic uses the same bandwidth as the forward traffic
- Implements Superior Cancellation Performance
- Bandwidth gain up to 33%
- Flexible network scenarios are used (SCPC, MCPC)
- Best efficiency with ACM
- Automated Equalink
- Performs Pre-distortion to compensate for the effects of imperfections in the filters and amplifiers of the satellite
- Supports Linear & Non-Linear Links
- Supports Saturated Transponders
- Supports 16/32/64 APSK
- Bandwidth Gain up to 10% (or 2GB)
- Clean Channel Technology:
- As a result of drive for standards, key players in the satellite industry have called for a new satellite transmission standard (S2 Extensions) to expand the existing DVB-S2 standard, specifically for professional satellite links.
- Open Standards such as DVB-S2 and S2 Extensions allow for:
- Interoperability and avoid vendor lock-in
- Increase in the profitability of the industry by creating an economy of scale and reducing the cost of sitcom equipment
- Today S2 Extensions already provide gains up to 37% compared to DVB-S2 through implementation of clean Channel Technology. These gains exceed the results by proprietary systems in the market
- Clean Channel Technology involves 7 improvements in S2 Extensions:
- Smaller Roll-offs
- Advanced Filtering of Satellite Carriers
- Increased Granularity in MODCODs
- 64APSK support
- Linear and Non-linear MODCODs
- Better implementation of MODCODs
- Wideband Support (up to mbaud)
- Clean Channel Technology can be offered as a software field upgrade so that customers can immediately field upgrade so that customers can immediately benefit up to 15% gain compared to DVB-S2 through implementing a lower Roll-off factor (5/10/15%) and an advanced filtering technology.
- Best-of-Trade-Equipment
- Emerging Hubs and Modems support medium and high rate data communication based on the DVB-S2 and S2 Extensions
- Each Equipment embeds the latest innovative technologies to fully optimize IP Trunking and IP backbone networks over Integrated Satellite/Wireless/Fiber Solutions for 5G.
- No extra or new ground infrastructure (antenna or amplifier) needs to be acquired to enable higher efficiencies.
- Next to hubs and moderns, peripheral equipment such as redundancy Switches and Frequency Converters provide the Trunking and Backbone networks with extra stability and
- Hubs and Moderns are installed on each side of the link.
- Networks in Point-to-Point, Point-to-Multipoint (star) or Multipoint-to-point configuration are supported through Single-channel-per-Carrier (MCPC) technologies.
- Within the same Carrier different Services such as data, video, voice, voIP, Wifi, WiMAX, GPRS, 3G/4G can be aggregate using MAP.
- Through the multi-service hub, Service providers with their respective customers are connected with a common forward carrier.
- The return technology can be SCPC or MF-TDMA depending on the return rate, the size of the remote or the network configuration.
- By aggregating the data traffic in a common forward carrier and combing equipment in a single hub, important CAPEX and OPEX savings can be made.
- Extra bandwidth gains are achieved by implementing ACM, clean channel Technology and Cross-Layer-Optimization technologies on top of the Multi-Service network.
- The Multi-service network also allows the service provider to provider IP access service provider to provide IP access service on a direct way or an indirect way (Backhaul, Trunking) to the end user.
- The hub provides internal and interface (RF, IP power Supply)
- The internal redundancy is conceived as two fully redundant chains.
- When there is a failure an automatic switch over to the other chain is performed.
- Even during service windows there is limited downtime since upgrades can be performed on one of the chains with the other chain active in a previous version.
- A failure in the RF path is resolved by switching to the alternative RF interface.
- Multiservice Access Platform (MAP) is a scalable, integrated system that can provide a wide range of voice, video and data services in a single chassis.
- A MAP can be located at the customer premises, in the local Loop/ Last mile or at the carrier’s point of presence (POP).
- Efficient Carrier Grade Gateway and Consumer Terminal Concept
- A typical Broadband solution is based on the Sat3play platform
- The platform provides the means to establish an “always-on” two-way IP Connectivity.
- The basic IP connectivity between Hub and Modem is extended with Quality-of-Service (QoS) in forward and return allowing the deployment of different services.
- QoS is the capability to provide better service to selected network traffic over various technologies such as Ethernet, frame relay, ATM or IP.
- The gateway contains management functionalities to monitor, configure and control all worldwide remotes.
- The Gateway provides all necessary infrastructures to receive and transmit IP data from and to the terminals.
- The Gateway has redundancy on all layers (user, control, management) equipment; RF signal and mains supply inputs.
- Gateways are points of entrance and exist from a communication network.
- Viewed as a physical entity, a gateway is that node that translates between two otherwise incompatible networks or network segments.
- Gateway performs code and protocol conversion to facilitate traffic between data highways of differing architecture.
- A GATEKEEPER is a device that manages an IP network, supporting all gateways, and a gatekeeper e.g low average-to-peak ratios in the traffic Profile. This results in high broadband user experience.
- Unique Design:
- The design of the compact modem and the lightweight low power outdoor equipment; the cost and “Look and Feel” of the terminal is in line with the consumer market requirements
- Lowest Consumer Acquisition Cost:
- With the lowest terminal cost on the market and a unique Do-it-yourself installation, the total customer acquisition cost is not a deterrent factor for capturing new subscribers.
- Self-Installation at Zero:
- Value Added Logistics
- Terminal Customization
- New Business Models, Retail outlet Channels and e-commerce
- Zero CAPEX Internet Service Providers Satellite System
- The require satellite system is Operated as Single-Service-Provider Platform AND Multi-Service-Provider Platform
- On a multi-Service-Provider Platform, new ISPs can start with a Zero CAPEX and the ability to rollout services immediately
- Different Service Providers Share the same HARDWARE and CAPACITY while they are capable of managing their own Customer base and Service Configuration.
- Unlimited Scalability: the total number of users in the Satellite system scales without System limitation. The addition of capacity in order to accommodate more users or offer better QoS comes with an almost linear increase of investment result.
On the other hand, satellite capacity represents the largest cost element in the total cost of Ownership (CTO). Efficient usage of satellite capacity is therefore mandatory.
- The End-Customer is expectation for Satellite broadband offerings are:
- Monthly rate on par with terrestrial broadband services
- Volumes as needed
- True broadband experience-Implementing FUP which assures that all broadband customers enjoy the same experience and have access to quick and reliable service at all time.

Court Dismisses N1Bn Suit against MTN, Awards N3m Costs

A Federal High Court in Lagos has dismissed a N1 billion lawsuit filed against MTN Nigeria Communications Plc by Walls and Gates Ltd and Okechukwu Udeichi, its managing director, over alleged copyright infringement, breach of confidentiality, and trademark violations arising from MTN’s 20th anniversary promotional campaign.

Delivering judgement on Tuesday, Justice Ayokunle Faji held that the plaintiffs failed to establish any legally protectable right in their proposal titled “20 for 20”, describing the action as frivolous, speculative, and vexatious.
The court dismissed the suit in its entirety and awarded N3m in costs against the plaintiffs.
The plaintiffs instituted the action under Suit No. FHC/L/CS/1935/2021, alleging that MTN unlawfully used their “20 for 20” proposal, which they claimed to have submitted to the telecoms company on 17 September 2019, ahead of MTN’s 20th anniversary celebration in 2021.
They argued that MTN’s anniversary promotion, in which 20 sport utility vehicles were given out to subscribers, emanated from their proposal and amounted to infringement of their copyright, confidential information, and trademark.
Based on those claims, the plaintiffs sought N1bn in damages or, alternatively, an order directing MTN to render an account of revenue generated from the promotion and remit 50 per cent of it to them.
MTN denied the allegations, contending that the proposal was an unsolicited business idea that imposed no contractual or confidential obligation on the company.
The telecoms firm maintained that its 20th anniversary programme was independently developed and that the plaintiffs’ document was merely a general business concept not protected under Nigerian copyright law.
MTN further argued that the plaintiffs lacked a valid registered trademark and failed to demonstrate access to or copying of any protected expression.
In resolving the dispute, Justice Faji noted that the plaintiffs conceded during oral submissions that they failed to prove their claim of trademark infringement, leaving only the issues of alleged breach of confidentiality and copyright infringement for determination.
On confidentiality, the court held that no confidential relationship existed between the parties.
Justice Faji observed that before sending the proposal to MTN, the plaintiffs had already submitted it to the Nigerian Copyright Commission and relied on it for a trademark application, thereby placing the document in the public domain.
The judge further noted that after transmitting the proposal to MTN, the plaintiffs admitted circulating it to other organisations, which extinguished any claim to confidentiality.
According to the court, MTN had no obligation to respond to an unsolicited proposal in the absence of a contractual, fiduciary, or business relationship, or a non-disclosure agreement.
On the allegation of copyright infringement, the court held that registration with the Nigerian Copyright Commission does not confer copyright, stressing that Nigerian law protects expressions, not ideas or business concepts.
Justice Faji ruled that the plaintiffs’ “20 for 20 Millennium Promotion” amounted to no more than an idea of rewarding customers during an anniversary celebration and lacked the originality and intellectual effort required for copyright protection.
He described the proposal as a bare business concept devoid of original qualities capable of attracting copyright. The judge also held that MTN’s use of the phrase “MTN 20th Anniversary” was a natural description of an anniversary event and did not originate from any protectable work of the plaintiffs.
He further relied on evidence showing that MTN affiliates in other jurisdictions had implemented similar anniversary reward ideas before the plaintiffs’ proposal.
Justice Faji characterised the suit as a “gold-digging exercise” aimed at forcing a commercial relationship on MTN. He criticised the plaintiffs for using MTN’s trademark in their proposal without authorisation and then seeking to ground a billion-naira claim on the same document, adding that the case wasted valuable judicial time.
While affirming that citizens should have access to the courts, the judge stressed that such access must be limited to suits with prima facie merit.
He therefore awarded N3m in costs in favour of MTN, holding that costs must follow the event.
The court accordingly dismissed the suit in its entirety and ordered the plaintiffs to pay the awarded costs to the defendant.

Nigeria, Egypt to Lead Africa’s Data Center Boom

Africa’s data center landscape is rapidly evolving from small, isolated initiatives into a large-scale, fast-paced expansion.

According to Africa Telecom Review, between 2025 and 2030, capacity demand is expected to soar, driven by rising cloud adoption, generative AI workloads, and the growth of digital services.
Leading this momentum are Nigeria in West Africa and Egypt in North Africa, which are drawing significant investment, carrier-neutral facilities, and increased interest from hyperscalers, even as developers and governments work to overcome challenges in power, connectivity, and talent.
Nigeria: West Africa’s Gateway to Scalability
Nigeria’s data center market has rapidly shifted from discussions to active development. Driven by a vibrant digital economy, a large mobile-first population, and a dynamic startup ecosystem, Lagos has emerged as the prime location for both colocation facilities and hyperscale projects.
Nigeria’s data center market is expanding rapidly, with an estimated 136.7 MW capacity in 2025 and projections to reach 279.4 MW by 2030 at a 15% CAGR, driven by recent facilities such as Equinix’s LG2.3 expansion in Lagos, and upcoming projects including MTN Nigeria’s 1,500-rack center and new 38-MW and 24-MW facilities under construction.
However, growth is challenged by severe power constraints, as Nigeria’s grid, capable of about 6,000 MW, fails to meet the nation’s total demand (100,000 MW), forcing data centers to rely on costly backup generation like diesel and gas, with limited current adoption of renewables despite some efficiency gains.
Growing demand from enterprises, banks, telcos, and government platforms for low-latency, sovereign hosting is driving a fundamental shift away from dependence on foreign landing points and offshore cloud regions. Developers are answering this need with multi-purpose campuses that offer carrier neutrality, cloud on-ramps, and edge infrastructure tailored for content delivery, fintech, and e-commerce surges.
The business case is strong and industry studies consistently rank Nigeria’s market growth and capacity outlook among the fastest-rising on the continent through 2030.
Egypt: The North African anchor
Egypt’s strategic geography, sizeable domestic market, improving policy environment, and Digital Egypt initiative have made it a prime destination for large-scale data hub projects. Cairo and the Nile Delta corridor offer fiber connectivity routes to Europe and the Middle East, and recent corporate deals and project pipelines point to a race to build hyperscale-ready campuses.
As of mid-2025, Egypt has 15 operational submarine cables with three more under construction. The country is targeting 18 by year-end to enhance low-latency access to Europe and Asia and the data center market is projected to grow from USD 278 million in 2024 to USD 694 million by 2030 at a robust pace.
These Egyptian developments matter beyond national borders as a consolidated Cairo hub creates new routing options and resiliency for MENA traffic and provides another competitive alternative to Western European clouds and submarine routes. For pan-African architects, Egypt represents both a distribution point and a home market for AI-scale infrastructure.
Demand Drivers and the AI Inflection Point
Two intertwined forces are powering the boom. First, enterprise cloud migration, digital payments, and streaming service growth require regional capacity to meet latency and sovereignty demands. Second, the rise of AI, from localized language models to enterprise inference farms, is intensifying the need for dense compute that is both scalable and economical.
According to McKinsey, the expansion of data centers is crucial for Africa’s businesses and consumers to achieve global competitiveness. Its latest report estimates that an investment of USD 10 billion to USD 20 billion in new capital is required to achieve this. As a result, this investment could unlock an estimated revenue pool of USD 20 billion to USD 30 billion across the data center value chain by 2030.
Furthermore, the firm projects that AI-driven demand for data center capacity could grow significantly, increasing by 3.5 to 5.5 times its current base within the same timeframe, translating to a total installed capacity of 1.5 to 2.2 GW by 2030.
The Infrastructure and Policy Hurdles
Despite the strong growth outlook, developers are contending with significant challenges. Power availability and grid stability remain the biggest obstacles to scaling quickly, often forcing projects to rely on costly hybrid energy setups that blend grid supply, on-site generation, and renewable sources.
By 2025, industry analysts had already identified power constraints as a major factor slowing data center rollouts across EMEA, highlighting why energy planning has become the decisive factor for African deployments.
Additional barriers include slow permitting processes, land acquisition difficulties, high import costs for specialized equipment, and a shortage of skilled technicians trained in modern data center operations.
For investors, managing these operational risks alongside rising demand will require stronger public–private collaboration and more innovative financing models.
Local Partnerships and the Path Forward
The coming five years will be critical for Nigeria and Egypt. By simplifying regulatory processes, strengthening grid infrastructure, and promoting green energy, both countries can establish themselves as leading data center hubs in Africa. For operators and cloud providers, achieving success will rely on providing reliable, sovereign, and energy-conscious capacity that supports both enterprise needs and AI-driven workloads.
Nigeria and Egypt are leading the charge, each offering distinct advantages that, together, are reshaping the continent’s digital backbone. The potential rewards are substantial: improved latency, local cloud sovereignty, and a strong foundation for AI-powered economies.

xAI Faces Backlash Over Grok’s ‘Digital Undressing’ Images

Elon Musk’s xAI is under intense scrutiny after its AI chatbot, Grok, generated a flood of sexually explicit images through user prompts known as “digital undressing,” including some appearing to depict minors.

Grok
Users have exploited Grok to strip clothing from images—primarily of women, often real individuals—and pose them suggestively. Reports from last week highlighted cases involving apparent underage subjects, sparking alarms over child sexual abuse material.
This incident amplifies risks of unregulated AI on social platforms. Critics argue it breaches local and global laws, endangering vulnerable people, especially children.
xAI and Musk claim swift measures on X, such as content removal, account bans, and law enforcement collaboration. Yet, Grok persists in producing sexualised women’s images despite these pledges.
Musk’s public disdain for “woke” AI and censorship, coupled with reported internal resistance to Grok safeguards, fuels the fire. xAI’s diminished safety team reportedly shrank just before the surge.
Unique Integration Sparks Spread
Unlike Google’s Gemini or OpenAI’s ChatGPT, Grok embeds directly into X, enabling public tagging and instant, visible replies. This accelerated non-consensual image sharing.
The trend ignited in late December with bikini requests, escalating to explicit manipulations without consent. Research reveals over half of Grok’s people images show minimal clothing—mostly women—with a disturbing fraction featuring apparent minors.
Grok has honoured some underage explicit prompts, clashing with xAI’s policy against sexualisation or child exploitation. Enforcement remains spotty.
Grok later admitted safeguard failures, deeming such content illegal and banned, while urging reports to authorities. Musk vowed repercussions for violators.
Regulatory Scrutiny Mounts
Detractors link Musk’s anti-moderation views to lax controls, noting his resistance to image-tool limits amid rising internal red flags.
Global regulators respond: Europe, India, and Malaysia probe; Britain’s media watchdog urgently engages Musk’s firms over explicit and child content.
Experts note existing tech can curb misuse but demands compromises like delayed replies and rigid filters. Absent these, platforms invite grave harm.
