NWDAF: How 5G is AI Native by Essence

Posted on by Mira Abdulrahman

The evolution of telecommunications networks has always been characterized by increasing complexity and intelligence. As we’ve moved through successive generations of wireless technology, I’ve observed a consistent trend toward more adaptive, responsive systems. With 5G, this evolution has reached a critical inflection point by introducing the Network Data Analytics Function (NWDAF) a component that fundamentally transforms how networks operate and adapt.

NWDAF, introduced in the 5G Core architecture starting from Release 15 and continuing to evolve toward 6G, represents a pivotal element in the Service-Based Architecture (SBA). More than just another network component, it embodies a philosophical shift toward data-driven, intelligent network operations that anticipate the needs of both users and applications.

At its core, NWDAF serves as a standardized network function that provides analytics services to other network functions, applications, and external consumers. Its functionality spans the entire analytics lifecycle: collecting data from various network functions (including AMF, SMF, PCF, and NEF), processing and analyzing that data, generating actionable insights and predictions, and feeding decisions back into the network for optimization and policy enforcement.

I often describe NWDAF as the “central intelligence of the network”—a system that transforms raw operational data into practical insights that drive network behavior. This transformation is not merely incremental; it represents a fundamental reimagining of how networks function.

The necessity for NWDAF becomes apparent when we consider the demands placed on modern networks. Autonomous networks require closed-loop automation for self-healing and self-optimization—capabilities that depend on the analytical insights NWDAF provides. Quality of Service assurance increasingly relies on the ability to predict congestion, session drops, or mobility issues before they impact user experience. Network slicing, a cornerstone of 5G architecture, depends on real-time monitoring and optimization of slice performance. Security analytics benefit from NWDAF’s ability to detect anomalies or attacks through traffic behavior pattern analysis. Furthermore, NWDAF’s flexible deployment model allows it to operate in either central cloud environments or Multi-access Edge Computing (MEC) nodes, enabling localized decision-making where appropriate.

The integration of NWDAF with other network functions occurs through well-defined interfaces. The Np interface facilitates data collection from various network functions. The Na interface enables NWDAF to provide analytics to consumers. The Nnef interface supports interaction with the Network Exposure Function, while the Naf interface enables communication with Application Functions. This comprehensive integration ensures that NWDAF can both gather the data it needs and distribute its insights effectively throughout the network.

The analytical capabilities of NWDAF span multiple dimensions. Descriptive analytics provide visibility into current network conditions, including load metrics, session statistics, and mobility patterns. Predictive analytics enable the network to anticipate issues before they occur, such as congestion prediction, user experience degradation forecasts, and mobility failure prediction. Looking forward, prescriptive analytics will eventually allow NWDAF to suggest automated actions, such as traffic rerouting or slice reconfiguration, further enhancing network autonomy.

As we look toward 6G, NWDAF is poised to evolve into an even more sophisticated component of network architecture. I anticipate the development of an AI/ML-native architecture where NWDAF evolves into a Distributed Intelligence Function. Federated learning approaches will enable cross-domain learning without requiring central data sharing, addressing privacy and efficiency concerns. Integration with digital twin technology will allow simulated networks to feed NWDAF with predictive insights, enhancing planning and optimization. Perhaps most significantly, NWDAF will increasingly support intent-based networking, where user intentions are translated directly into network behavior without requiring detailed technical specifications.

The journey toward truly intelligent networks is just beginning, and NWDAF represents a crucial step in that evolution. By embedding analytics and intelligence directly into the network architecture, 5G has laid the groundwork for networks that don’t just connect—they understand, anticipate, and adapt. This foundation will prove essential as we continue to build toward the even more demanding requirements of 6G and beyond.

Mobile Private Network

Posted on by Mira Abdulrahman

Private networks are dedicated communication networks built for a specific organization or use case

Benefits

  • Enhanced security and data privacy
  • Improved network performance and reliability
  • Customized coverage and capacity
  • Integration with existing systems and infrastructure

A private (mobile) network is where network infrastructure is used exclusively by devices authorized by the end-user organization.

Typically, this infrastructure is deployed in one or more specific locations which are owned or occupied by the end-user organization.

Devices that are registered on public mobile networks will not work on the private network except where specifically authorized.

Formally these are known as ‘non-public networks’ however the term private network is more commonly used across vertical industries.

Drivers of having a 5G Private network

Network Performance: with eMBB, URLLC and MMTC, 5G is very capable in terms of network performance

5G Security: The fifth generation of networks is more secure than the 4G LTE network because it has identity management, privacy, and security assurance

New Spectrum in 5G: availability of shared and dedicated 5G spectrum in several bands

Network Coverage: With 5G network, you control where to deploy your gNB

Private Networks Deployment Models

SNPN, Standalone Non-Public Network

NPN is deployed as an independent, standalone network

Private company has exclusive responsibility for operating the NPN and for all service attributes

The only communication path between the NPN and the public network can be done optionally via a firewall

standalone network. Under this deployment model, all network functions are located within the facility where the network operates, including the radio access network (RAN) and control plane elements. Standalone, isolated private networks would typically use dedicated spectrum (licensed or unlicensed) purchased through a mobile network operator (MNO) or, in some cases, directly from government agencies.

PNI-NPN: Public Network Integrated – Non Public Network

  • NPN deployed with MNO support: hosted completely or partially on public network infrastructure
  • e.g. using Network Slicing
  • PNI-NPN has different variants we are going to explain some of them in the coming section

PNI-NPN: Deployment with shared RAN

Shared RAN with dedicated Core

NPN and the public network share part of the radio access network, while other network functions remain separated.

This scenario involves an NPN sharing a radio-access network (RAN) with the service provider. Under this scenario, control plane elements and other network functions physically reside at the NPN site.

This type of deployment enables local routing of network traffic within the NPN’s physical premises, while data bound for outside premises is routed to the service provider’s network. 3GPP has specifications that cover network sharing. (A variation of this deployment scenario involves the NPN sharing both the RAN and control plane functions, but with the NPN traffic remaining on the site where the NPN is located and not flowing out to the public network.)

PNI-NPN: Deployment with shared RAN and Control Plane

Shared RAN and core control Plane.

Both RAN and Core Sharing from control side, with the RAN and Core elements managed by the Public 5G network.

NPN only handles user plane connectivity.

This scenario involves an NPN sharing a radio-access network (RAN) with the service provider. Under this scenario, control plane elements and other network functions physically reside at the NPN site”

PNI-NPN: NPN Deployment in public network

5G Public-Private Network Slice

NPN hosted by the public network

Complete outsourcing of the network, where devices on the private network utilize the Public 5G network RAN.

This scenario can be implemented by means of network slicing

The third primary type of NPN deployment is where the NPN is hosted directly on a public network. In this type of deployment, both the public network and private network traffic are located off-site.”

Through virtualization of network functions and in a technique known as network slicing, the public-network operator of the private network partitions between the public network and the NPN, keeping them completely separate.

Challenges of Private Network

Spectrum and Regulations

Limited Spectrum Options: Securing suitable spectrum can be challenging, especially in densely populated or highly regulated regions where spectrum allocation is scarce.

Regulatory Hurdles: Navigating complex regulatory environments to acquire spectrum licenses can be time-consuming and costly, often requiring compliance with specific national or regional regulations.

High Initial Cost

Infrastructure Investment: Setting up a private network requires substantial upfront investment in infrastructure such as base stations, antennas, and network equipment.

Operational Expenses: Beyond initial setup, ongoing operational costs include maintenance, upgrades, and personnel training, contributing to the overall cost burden.

Knowledge acquisition or outsourcing

Technical Expertise: Establishing and maintaining a private network demands specialized knowledge in network design, integration, security, and optimization.

Outsourcing Challenges: Depending on internal resources versus outsourcing, finding capable vendors or partners with expertise in private network implementation can be challenging, affecting project timelines and quality.

Availability and Scope

Geographical Coverage: Ensuring adequate coverage across the desired operational area without compromising signal strength or reliability can be complex, particularly in challenging terrains or remote locations.

Scalability: Designing networks that can scale effectively as operational needs grow, without sacrificing performance or security, requires careful planning and sometimes iterative adjustments.

Integration with Existing IT/OT Systems

Legacy Systems: Many enterprises operate legacy operational technology (OT) systems that aren’t designed to interface with IP-based private networks.

Interoperability Issues: Ensuring seamless integration between IT/OT systems, existing network infrastructure, and the new private network requires careful system design and often bespoke solutions.

Data Flow & Security Consistency: Synchronizing real-time data and maintaining consistent security policies across heterogeneous systems can be complex.

Return on Investment (ROI) and Business Justification

Unclear Business Models: Enterprises often struggle to quantify the ROI of private networks, especially when benefits like reliability and security are intangible.

Cost vs. Benefit Uncertainty: Without clear use cases (e.g., predictive maintenance, robotics, digital twin), the business case can remain weak, delaying decision-making.

Is the Customer Always Right?

Posted on by Mira Abdulrahman

Understanding the Dynamics Between System Integrators, Vendors, and Customers

The age-old adage, “The customer is always right,” has been a guiding principle in the world of business for decades. However, when it comes to the complex realm of system integration and vendor interactions, this notion may not always hold true. In this article, we delve into the delicate balance of power and decision-making between system integrators, vendors, and customers, and explore when it may be necessary to say no to a customer’s requests.

The Customer’s Perspective

Customers play a vital role in the success of any business endeavor. Their needs, requirements, and feedback shape the products and services offered by vendors and system integrators. Customers often come with specific expectations and demands, driven by their unique goals and priorities. The customer-centric approach emphasizes the importance of listening to the customer, understanding their requirements, and delivering solutions that meet or exceed their expectations.

The Role of System Integrators and Vendors

System integrators and vendors serve as the bridge between customers and technology solutions. They possess specialized knowledge, expertise, and resources to design, implement, and support complex systems and solutions. While their primary goal is to satisfy customer needs, system integrators and vendors also have a responsibility to deliver high-quality, reliable products and services that align with industry standards and best practices.

Saying No: When Should System Integrators and Vendors Push Back?

Despite the emphasis on customer satisfaction, there are instances where it may be necessary for system integrators and vendors to say no to a customer’s requests. Some common scenarios include:

  • 1. Technical Feasibility: If a customer requests a solution that is technically infeasible or goes against industry standards, system integrators and vendors may need to push back and propose alternative approaches.
  • 2. Scope Creep: Customers may often expand the scope of a project without considering the potential impact on timelines, resources, and budgets. In such cases, system integrators and vendors may need to set clear boundaries and manage customer expectations.
  • 3. Security and Compliance: In today’s digital landscape, cybersecurity and data privacy are top priorities. If a customer’s request poses security risks or non-compliance with regulations, system integrators, and vendors must prioritize safeguarding sensitive information.
  • 4. Resource Constraints: Customers may demand quick turnaround times or customized solutions that strain resources and impact the quality of deliverables. System integrators and vendors may need to communicate effectively with customers to manage expectations and maintain service standards.

Resolving the Dilemma: Strategies for Effective Communication and Collaboration

To navigate the challenges of balancing customer demands with technical limitations and industry standards, system integrators and vendors can adopt the following strategies:

  • 1. Open Communication: Establishing clear channels of communication with customers is crucial. System integrators and vendors should actively listen to customer requirements, provide transparent feedback, and collaborate on finding mutually beneficial solutions.
  • 2. Educating Customers: System integrators and vendors can educate customers on best practices, emerging technologies, and industry trends. By sharing expertise and insights, customers can make informed decisions that align with their long-term goals.
  • 3. Setting Expectations: From the inception of a project, setting clear expectations regarding timelines, deliverables, and potential challenges is essential. System integrators and vendors should communicate proactively to avoid misunderstandings and scope creep.
  • 4. Collaborative Problem-Solving: When faced with conflicting priorities or technical constraints, system integrators, vendors, and customers can engage in collaborative problem-solving. By brainstorming alternatives and exploring different approaches, a consensus can be reached that satisfies all stakeholders.

In Conclusion

While the customer’s needs and preferences are paramount in the world of system integration and vendor relationships, there are situations where saying no is necessary to uphold standards, ensure security, and deliver value. By fostering open communication, educating customers, setting clear expectations, and engaging in collaborative problem-solving, system integrators and vendors can navigate this delicate balance effectively. Ultimately, the key lies in fostering a relationship built on trust, respect, and a shared commitment to success.

The Case for Open RAN and Open Networks

Posted on by Mira Abdulrahman

Advocates of Open RAN (Radio Access Networks) and open networks champion their potential to revolutionize the telecommunications industry by promoting flexibility, innovation, and cost-effectiveness.

Open RAN refers to a disaggregated approach to building wireless networks, using open and interoperable interfaces. This model allows operators to mix and match components from different vendors rather than being locked into a single supplier, fostering a competitive ecosystem.

Proponents argue that this could lead to significant cost reductions, especially in deploying 5G networks, as it drives down hardware costs and encourages innovation through increased competition. Additionally, open networks enable greater adaptability, allowing network operators to quickly implement new technologies and services, which is crucial in a rapidly evolving digital landscape.

Moreover, open networks are seen as a critical step toward enhancing network security and resilience. By diversifying the supplier base, operators can reduce dependency on any single vendor, mitigating risks associated with vendor-specific vulnerabilities and supply chain disruptions. The interoperability inherent in open RAN can also facilitate more robust security practices, as operators can integrate best-of-breed security solutions from various vendors.

This flexibility is particularly important given the rising concerns over cyber threats and the geopolitical complexities affecting the telecom supply chain. Consequently, many industry experts and regulators view open RAN and open networks as a pathway to not only technological advancement but also national security and economic resilience.

**The Legacy of Proprietary Telecom Networks**

On the other hand, supporters of legacy proprietary telecom networks argue that these systems offer unmatched reliability, performance, and security that have been refined over decades. Traditional telecom networks, built on established partnerships with trusted vendors, provide end-to-end solutions with tightly integrated hardware and software, ensuring optimal performance and stability. This integration is particularly vital for critical communications infrastructure, where any downtime or performance issues can have significant repercussions. Legacy systems also benefit from rigorous testing and certification processes, which help to maintain high standards of quality and reliability that are crucial for maintaining consumer trust and ensuring uninterrupted service.

Furthermore, critics of open RAN and open networks caution against the potential downsides of moving away from established proprietary systems. The complexity of managing and integrating multiple vendors’ components could lead to interoperability challenges and increased operational overhead. There is also the risk that the rapid pace of innovation in an open ecosystem could outstrip the ability of operators to thoroughly vet and secure new technologies, potentially introducing vulnerabilities. Additionally, the transition to open RAN may require substantial upfront investments in new infrastructure and training, posing significant barriers for smaller operators and developing regions. As such, proponents of legacy networks argue that the proven track record of proprietary systems offers a safer and more reliable path forward, particularly in contexts where stability and security are paramount.

NFV deployment validation using INOS

Posted on by Gwen Edwards

Network Function Virtualization (NFV), is becoming increasingly important as mobile networks are being asked to handle an ever-growing number of connected devices and new use cases. In this article, Amr Ashraf, RAN and Software Solution Architect and Trainer, describes the benefits of NFV, capabilities and deployment considerations. Plus, we take a quick look at how Digis Squared’s powerful AI-tool, INOS, can help in the deployment validation of NFV.

Network Function Virtualization

Mobile virtualization – also known as network function virtualization (NFV) – is a powerful technology that has the capability to transform the way mobile networks are designed, deployed, and operated.

  • NFV enables the creation of virtualized mobile networks, and the isolation of different types of traffic on the same physical network infrastructure.
  • The creation of different virtual networks for different types of services or different user groups.
  • Multiple independent network operators to share a common infrastructure,
  • And improves the security of the network.

In this article, Amr Ashraf describes the benefits of NFV, capabilities and deployment considerations. Plus, we take a quick look at how Digis Squared’s powerful AI-tool, INOS, can help in the deployment validation of NFV.

The future of mobile network functions is virtual

Mobile virtualization is becoming increasingly important as mobile networks are being asked to handle an ever-growing number of connected devices and new use cases.

NFV & Infrastructure Sharing. One of the main benefits of mobile virtualization is that it allows for multiple independent network operators to share a common infrastructure. This can help to reduce the costs and complexity of building and maintaining mobile networks, and can also help to improve coverage and capacity in areas where it would otherwise be difficult or expensive to deploy new infrastructure.

NFV & Security. Mobile virtualization also helps to improve the security of the network by isolating different functions and providing a secure environment for each virtual network. This makes it an ideal solution for enterprise customers who need to maintain high levels of security for their sensitive data.

Deployment flexibility. Mobile virtualization is supported by software-based virtualized network functions (VNFs), which can be run on standard servers and storage systems, rather than specialized hardware. This makes it easy to scale and adapt the network to changing requirements. Additionally, it also makes it possible to deploy mobile virtualization solutions in a variety of different environments, including on-premises, in the cloud, or at the edge of the network.

NFV & 5G customisations. It’s worth noting that mobile virtualization is a key technology in building the 5G network. 5G network standards are designed to support network slicing, which can create multiple isolated virtual networks on top of a common physical infrastructure. This makes it possible to create customized solutions for different types of users and use cases, such as providing high-bandwidth services for multimedia applications, or low-latency services for industrial automation and control.

NFV is the future, and the future is now. Mobile virtualization is a rapidly evolving technology with considerable potential to transform the way mobile networks are designed, deployed, and operated. In the coming years, we expect to see more and more operators turning to mobile virtualization to meet the growing demands on their networks and stay competitive in the fast-changing mobile landscape.

Orchestration

Implementing mobile virtualization can present a number of technical challenges, including the management and orchestration of virtualized network functions (VNFs) and ensuring network security. Managing and orchestration of VNFs is a complex task, which involves provisioning and configuring VNFs, as well as ensuring their availability and performance. This is complicated by the fact that VNFs are software-based and can be deployed on a variety of hardware and virtualization platforms.

Security

As VNFs are software-based, they can be targeted by cyber-attacks just like any other type of software. Therefore, ensuring network security is vital when implementing mobile virtualization.

Additionally, virtualized networks may be vulnerable to new types of attacks that exploit the virtualization itself.

NFVO. One of the key solutions to these challenges is the use of network function management and orchestration (NFVO) systems. NFVOs automate the provisioning, configuration, and management of VNFs, and they help to ensure that the VNFs are highly available and perform well. They also play an important role in the orchestration of VNFs, which involves coordinating the actions of multiple VNFs to achieve a desired outcome.

Strong defences. Another key solution is the use of security solutions such as firewall, intrusion detection and prevention systems, secure VPN, and secure containers to protect the virtualized network, secure communication between virtualized functions, and protect virtualized infrastructure from unauthorized access.

Anomaly detection. Solutions based on artificial intelligence and machine learning can also be used to monitor and detect anomalies in the network, identify potential security threats, and take appropriate action to mitigate them.

Digis Squared recommend involving INOS Probe to undertake anomaly detection 24/7, and send these alerts to the CSP. Read more – Anomaly detection: using AI to identify, prioritise and resolve network issues.

Security strategy. In addition to these technical solutions, it’s also important to have a comprehensive security strategy in place to address any potential vulnerabilities and threats that may arise when implementing mobile virtualization. This can include implementing best practices for network design, conducting regular security assessments, and keeping systems and software up to date with the latest security patches and updates.

Skills & expertise. An often overlooked, yet important security consideration, is the need for skilled personnel who are well-versed in the technologies and best practices associated with mobile virtualization. As mobile virtualization is a complex technology that requires a deep understanding of network functions, security, and software development, it’s crucial to have a team of experts who can design, deploy, and maintain secure mobile virtualization solutions.

INOS & NFV

Drive testing can be used to validate the performance of virtualized network functions and ensure that they are providing the desired level of service. This can help to identify and troubleshoot any issues that may arise, such as poor performance or dropped connections. Drive testing can also be used to compare the performance of virtualized network functions with that of traditional, hardware-based network functions, in order to ensure that the virtualized functions are providing an equivalent or better level of service.

Digis Squared’s AI-solution INOS is an essential tool in the implementation and ongoing optimization of NFV. It helps to validate and troubleshoot virtualized network functions and ensure that they are providing an equivalent or better level of service compared to traditional, hardware-based network functions. Additionally, drive testing provides key information about the environment in which the network is deployed that can be used to optimize the deployment of virtualized network functions.

Conclusion

Mobile virtualization is a powerful technology that has the capability to transform the way mobile networks are designed, deployed, and operated. Key benefits it enables include,

  • The creation of virtualized mobile networks, and the isolation of different types of traffic on the same physical network infrastructure.
  • The creation of different virtual networks for different types of services or different user groups.
  • Multiple independent network operators to share a common infrastructure,
  • And improves the security of the network.

However, implementing mobile virtualization can present a number of technical challenges, including the management and orchestration of virtualized network functions (VNFs) and ensuring network security.

The use of network function management and orchestration (NFVO) systems, security solutions, AI/ML-based monitoring and anomaly-detection systems, and a comprehensive security strategy can help to mitigate these challenges.

Finally, NFV is a powerful, yet complex technology – it’s essential to work with an experienced team with deep expertise who can design, deploy, and maintain mobile virtualization solutions.

Many of the photos I’m using today have been taken by our staff. We want to share with you a sense of place and insights into our projects and what we’ve achieved.

Yemen is complex

Before the conflict in Yemen, telecoms was second only to oil and gas in generating revenue and foreign currency for the government.

After almost 8 years of conflict, over 23 million people need humanitarian assistance, and
over 5 million are displaced.

In such a disrupted society, the need for reliable communications between families and communities is vital.

But, the networks supported only legacy 2G voice and text messages – no WhatsApp, no email, no search, no apps, no interconnect, and no roaming. With incredibly limited and patchy coverage, and significant network instability there was almost no mobile data, and even person-to-person calls were unreliable, making it very difficult to keep in contact with loved ones inside the country and internationally.

Difficult terrain

As part of the country’s re-construction mega-project, the Yemeni Government in Aden assigned 4G licenses to Y-Tel.

Digis Squared won a competitive tender and was selected to deliver the entire major transformation program. The old 2G legacy systems were dramatically upgraded to best-in-class, cloud-based solutions – 4G at launch, with 5G ready elements.

I’m worried I’ve made that sound easy! The local Digis Squared team on the ground in Yemen used our processes and AI tools to assess what was needed, and working together with our remote teams, they defined the strategy and services, co-ordinated and selected vendors, and managed contracts, logistics and warehousing. They used our smart network planning tools, managed the physical network rollout and optimization, the back and front office implementation, network commissioning and dimensioning, everything through to network operations. We worked together with Y-Tel, the Ministry of Telecommunications in Aden, and the GSMA to drive delivery of the new network.

As part of this huge program, we established a NOC in our Cairo GNOC to ensure operational excellence and resilience. And we continue to carefully balance local and remote skills by investing in on-site training for a new generation of Yemeni engineers.

Re-calibrating an over-used term: digital transformation

This project is huge.

We have entirely transformed the capability, stability and capacity available, and delivered every element of the new 4G network for Y-Tel.

The Digis Squared Operations Team in Yemen have been enormously committed to the project, working in very difficult environments, 24 hours a day to achieve key targets within specific windows.

I would like to publicly thank them and acknowledge the impact their work will have on connectivity between communities in Yemen.

In June this year, we completed the on schedule first call, and the first 4G data connection, and the first ever mobile video call in country. These are massive milestones for our client Y-Tel and the local Digis Squared Team in Aden.

It is hard for us now, in this room here in Kigali, to imagine or remember life without mobile connectivity. The certainty that you can phone a loved one, and so much more: the ability to place an order via your phone, to send a photo to a friend, to make a video call and check your Dad is ok – we take all of this for granted.

The impact the project will have on the people of Yemen is hard to express. This project in Yemen re-calibrates the term ‘digital transformation’. The connectivity we are delivering for Yemen will truly transform lives, and improve the functioning of society.

Be connected. Be fast.

The “first calls” made in June mark the start of network operations and pave the way for the phased roll-out of infrastructure and portfolio of customer services.

The Y-Tel pre-launch marketing campaign is underway, and focuses on simple, straightforward commitments: be connected, be fast.

As the only non-Network Equipment Manufacturer delivering end-to-end Managed Services for mobile networks, this project in Yemen is very significant for the Digis Squared team.

If we can do this in Yemen, we can do this anywhere.

Luanda, Angola

Turning now to the second half of the presentation: Angola on the southwest coast of Africa. A very different place, but with some surprising similarities in population size and age. Civil War-ravaged Angola for 27 years until it finally ended in 2002.

Africell’s mission

In January last year, 2021, Africell won a competitive international tender for a telecoms license. Their mission was simple: to provide innovative, affordable and reliable mobile services, and lead a digital transformation in Angola – a country which has experienced decades of stasis and under investment in the mobile sector.

Fast forward to November last year: after a competitive international tender, Africell awarded Digis Squared a multi-year contract to provide end to end Managed Services to support their launch.

We moved fast. We created a local legal entity, set up an office, and in just one month mobilised and hired forty-four engineers, from Angola locally and across Africa.

Digis Squared has worked with Africell Group in other OpCos – in DRC, Sierra Leone and The Gambia, plus Uganda in the past – delivering enhancements to radio, core and VAS.

In Angola the end to end Managed Services contract covers everything from field to full NOC, all aspects of Radio, Core, BSS, VAS and field managed services, across the entire brand new network.

In April this year, the Africell Angola 4G mobile network went commercially live. Within 6 months Africell Angola had over 5 million subscribers. This is a significant success together for Africell and Digis Squared, and a significant transformation in service for subscribers.

5G boost to economy & innovation

In July, just 4 months after launch, we supported Africell in publicly demo’ing 5G for the first time in Angola, reaching speeds of 1 gigabit per second. 

Angola has one of the most advanced economies in sub-Saharan Africa, and the future rollout of 5G and private networks has the potential to boost the economy, drive innovation, security and performance even further.

Working together, we are looking forward to enabling that future 5G transformational capability.

Connecting communities

Today, network rollout is progressing and soon Africell Angola will expand to include cities and regions outside Luanda.

This project has been technically complex in scale and ambition, but the impact on people’s lives, and the ability to deliver change is very real.

Mobile services in Angola have never been faster, lower cost or more reliable.

Making change happen, together

Africell launched services in Angola in April this year with a promise to shake up the telecoms sector and lead a nationwide digital transformation.

As the first new mobile operator in almost two decades, the introduction of fresh competition has already led to improved network quality and security, reduced prices and increased consumption, and is delivering benefits for digital inclusion, education and healthcare.

Whilst Digis Squared has worked in over 25 countries in Africa and the Middle East, this project was our first in Angola, a new country and culture for us, and Africell.

Investing in the local team, using our solid existing processes and automated AI tools, balancing expertise in country, with experienced staff in our other offices when needed, we’ve been successful in setting up and delivering quickly, and delivering on schedule.

Africell Angola promised to change and make change happen, and together, we’ve done that.  

Conclusion

And what have we learnt from these projects?

  • Working in an almost war-zone is hard, but can be done.
  • Finding balance between staff in country, and a remote GNOC helps ensure stability, robustness and continuity.
  • Clear focus on aligned mission, and trust in working together is vital to success.
  • Building strong local teams, and investing in and enhancing skills, competence development and training, is really important to the way in which we work, and a clear commitment from the Digis Squared team to the project, the client, and the country we are working in.
  • In such a competitive market we are the only non-Network Equipment Manufacturer delivering end to end Managed Services, covering preventive and corrective maintenance in the field, up to full NOC including core, billing, charging and VAS.

When we are driven by the power of connecting people, together we can achieve anything.

With thanks to Africell, and Y-Tel.

First ever mobile video call in Yemen, on 5G-ready Y-Tel network

Posted on by admin

In Yemen, even simple person-to-person 2G calls are unreliable – this first ever mobile video call, marks a colossal transformation, only 18 months after Y-Tel initiated this major transformation program with Digis Squared.

Aden, YEMEN – 15 June 2022 – Y-Tel has made the first call on in its new 5G-ready network in Yemen, and the first ever mobile video call in the country. This significant technical milestone marks the start of the leap from legacy 2G to transformed 5G-ready network operations, and heralds a new era of stable calls and mobile data for the first time for the Yemeni people.

After the war, and as part of the re-construction mega-project across the country, the Yemeni Government in Aden assigned 4G telecommunications licenses to Y-Tel. Previously, Y-Tel ran only a legacy 2G network for voice and SMS, which like all Yemeni networks suffered from very patchy coverage, and significant network instability.

Following a rigorous selection process, the entire Y-Tel network major transformation program – covering everything from the entire network planning and design, through to vendor selection, end-to-end Radio on-site rollout, network core infrastructure implementation and integration, through to network go-live, and operations – was assigned in its entirety to Digis Squared, including end-to-end Managed Services and System Integration. Working throughout the pandemic, the highly motivated teams have solved complex technical and logistical issues to transform all aspects of capability, to deliver a world-class 5G-ready network in Aden, Yemen, and in parallel managed the current 2G legacy network, to keep the limited existing capability going, and migrate the subscribers to the new secure network.

“This on schedule first call, plus first 4G data connection and first ever mobile video call in the country are significant and exciting program milestones for our client Y-Tel and the Digis Squared Team,” shared Digis Squared COO Ahmed Zein.

“The impact of this major program on the Yemeni people can not be overstated. This is a country where even person to person calls are very unreliable, where there is incredibly limited coverage and almost no mobile data, making it very difficult to keep in contact with loved ones in the country and internationally,” Zein continued. “Until you have lived and worked here it is hard to imagine or remember life without mobile connectivity. We over use the term ‘digital transformation’ in our industry; I simply cannot express the impact this project will have on the people here in Yemen. The ability to phone a loved one, to place an order with a company, to send a photo to a friend – the connectivity we are delivering will truly transform lives, and improve the functioning of society. The benefit this project will bring to the Yemeni people, starting with Aden, is colossal.”

“Digis Squared have completely replaced and upgraded the legacy infrastructure, entirely transforming the capability, stability and capacity available, and delivered every element of this network for Y-Tel”, explained Zein. “Starting from a blank piece of paper, we have handled everything from network design and architecture, vendor and equipment selection, contract management, logistics and warehousing, physical network rollout and optimization, back and front office implementation, network commissioning and dimensioning, everything through to network operations – every element from the ground up. The old legacy systems have been dramatically upgraded to best-in-class cloud-based solutions. We have worked closely with the Y-Tel team, the telecom sector in Yemen, and the Ministry of Telecommunication.”

The transformed Y-Tel network will launch initially in Aden, before a phased national deployment. These “first calls” mark the start of network operations and pave the way for a phased roll-out of infrastructure and portfolio of customer services.

“This program in Yemen is incredible. I am immensely proud of our Digis Squared team in Yemen, and our global team who have worked together to achieve this entirely transformed network infrastructure, and the milestone first calls last week,” stated Digis Squared CEO Ziad Khalil. “This first ever mobile video call in Yemen is testament to the hard work, dedication and skill of our teams. It builds on our significant achievements in launching and operating the Africell Angola network earlier this year. If we can contribute to change people’s lives for the better, and completely transform, launch and operate a 5G-ready network, if we can do this in Yemen, we can do this anywhere.”

“After working closely together with Digis Squared for the last 18 months, it was a real thrill for me to make the first video call together with Zein!,” said Ahmed Gadallah, Vice Chairman of Y-Tel. “This reliable, and fast connectivity will bring such a dramatic improvement in communications to the Yemeni people, we can’t wait to bring our new fast 4G network to the people of Aden and then across Yemen. We have a very exciting time ahead of us!”
