Software Defined Networking (SDN) and Network Function Visualization (NFV) for 5G

By Andrew Aroh
5G will lead to a paradigm shift towards a landscape dominated by wireless connectivity. Major architectural changes are already taking place to accompany this shift:

- Network Function Virtualization (NFV) will be pivotal
- Software Defined Networking (SDN) both at the core and edge of the network will be deployed.
- The architectural changes will provide:
- Increased computing power
- Scalability
- Reduced operational costs
- Creative business models to enable differentiation
- 3GPP has defined a service-based architecture where flexibility and dynamic adjustments are the key drivers to meet performance and cost requirements. This architecture defines network functions which can be triggered by other services leveraging Virtualization and Network Slicing.
- As a reference, Newtec, early in 2019, announced that it would be collaborating with Wind River to utilize its Titanium cloud Virtualization Platform to develop a Newtec Dialog.
- Wind River’s complete Network Functions Virtualization (NFV) Software Platform Infrastructure will help Newtec leapfrog these 5G requirements.
- The Titanium Cloud Platform delivers the features needed to successfully build and deploys a virtualized network running multiple Virtual Machines. It also promises lower-cost, highly flexible, and scalable infrastructure and will provide customers with the ability to get better service access anywhere in the world.
- With SND and NFV Customers and service providers will be able to scale their services to quickly address changing requirements.
- Introduction To SND:
- SDN is a Radio Access Network for 5G wireless standards
- Software Defined Networking is based on Software Radio (also called Software Defined Radio – SDR)
- SDR is a device in which the supported air interface can be changed through a software only upgrade.
- SRD techniques has been used in a variety of military and high-end commercial radio devices to date, especially in spectrum monitoring.
- A conventional SDR design exploits specialized processors such as digital signal processors (DSPs) or Field Programmable Gate Arrays (FPGAs) on a specialized hardware board with embedded codes specific to the application. This technology might be termed “FIRMWARE RADIO” to reflect its lack of portability and dependence on specific hardware devices.
- In contrast, a general standard SDR design is implemented as portable software (high-lever codes) running on industry- standard equipment. This is termed “SOFTWARE RADIO”.
- Typically, all of the software is written in C and C++ running on the Linux operating system.
- The entire system, including the signal processing for the air-interface, is simply a collection of software applications that can run on any general purpose processor (e.g Pentium, Xeon, PowerPc, ARM).
- The software is designed to allow multiple processors to run on same CPU or board, enabling a single server or blade to support multiple different air-interfaces at the same time, with capacity dynamically shared among all operating air-interfaces.
- The applied station subsystem brings together a suite of technologies that together provide flexibility, scalability and cost-effectiveness to network operators.
- The core Software Radio technology enables true multi-standard operation and takes advantage of industry-standard COTs servers, reducing both CAPEX and OPEX and significantly reducing requirements for on-site maintenance
- The use of advanced multi-carrier RF heads supports multi-standard operation and dynamic capacity reallocation.
- A switched-fabric standard networking protocol in the front haul makes distributed antenna system (DAS) solutions economical
- IP everywhere in the backhaul and switch connection enables the use of commodity equipment and multiplex network links.
- These benefits are the direct consequences of software-centric approach to the radio access network (RAN).
- The multi-standard software can turn on any of a wide range of server platforms and exploit any of a range of backhaul, fronthaul and RF head equipment, all based around industry-standard, commercially available platforms and networking protocols.
- The applied subsystem enables carriers to allocate valuable spectrum and backhaul resources to broadband data capacity only in those cells where the customers using the broadband service are active at any given time.
- Consequently, with the subsystems, network operators can focus infrastructure investments on system configurations that not only meet their specific requirements for features and scalability at minimal cost, but also significantly enhance business model flexibility through enabling software-only upgrades and on-demand spectrum and capacity allocation.
- In fact the SDR applied subsystem networks in both microcell and innovative vehicle picocell, enterprise in-building, and home deployments can enjoy significant cost and flexibility advantages over conventional alternatives.
Reducing the cost and complexity of managing wireless-based networks for 5G
- This involves :
- Remotely access, monitor and control hybrid networks of terrestrial and satellite broadband network equipment including:
- Routers
- Switches
- Servers
- Hubs/ Gateways
- Fire walls
- Wireless Access Points
- VSAT MODEMS
- Antenna Controllers
- RF Amplifiers

FG Unveils Digital Economy Research Fund Scheme

The Federal Government has unveiled a N12bn Digital Economy Research Fund aimed at strengthening evidence-based policymaking and supporting Nigeria’s long-term digital transformation agenda.

Dr. Bosun Tijani, the Minister of Communications, Innovation, and Digital Economy, disclosed this in a statement issued on Saturday, announcing the launch of an expression of interest for the National Digital Economy Research Clusters.
“Today my heart is filled with deep joy as we announce the Expression of Interest for the National Digital Economy Research Clusters, a N12bn research funding scheme designed to place ideas, evidence, and research at the centre of Nigeria’s digital transformation,” the minister said.
According to him, the programme is being funded under Project BRIDGE, a federal initiative to deploy 90,000 kilometres of fibre optic backbone infrastructure across Nigeria to expand connectivity and enable a modern digital economy.
“This programme is being funded under Project BRIDGE, our initiative to deploy 90,000km of fibre optic backbone infrastructure across Nigeria to expand connectivity and enable a modern digital economy,” he said.
The minister noted that as the government expands digital infrastructure nationwide, research-backed approaches are required to ensure inclusive benefits.
“As we deepen our digital infrastructure coverage, thoughtful, evidence-based approaches are required to be deployed in society to ensure everyone benefits from this significant investment,” he added.
He observed that digital policy decisions are often shaped by market forces and political cycles rather than rigorous research and long-term thinking. “Too often, the ideas shaping digital policy come predominantly from markets and political cycles rather than from research, evidence, and long-term thinking,” the statement said.
Under the initiative, six national research clusters will be established across key pillars of the digital economy, including connectivity and meaningful use; digital public infrastructure and government services; digital skills and human capital development; digital economy and jobs; online trust and consumer protection; as well as artificial intelligence and emerging technologies.
The clusters will be led by up to 36 professors drawn from Nigerian universities, working alongside international academic partners, with more than 200 researchers, including postdoctoral fellows and PhD candidates, expected to generate policy-relevant research.
“For me, the goal goes beyond research output. We are looking for better policies that lead to stronger institutions and a more prosperous society,” the minister said.
He described the initiative as one of the ministry’s most meaningful programmes, noting that it is intended to produce ideas that will outlast any single administration. “Because nations that lead the future are not simply those that deploy infrastructure; they are the ones that cultivate ideas,” he said.
The ministry invited academic and research institutions interested in participating to review the Terms of Reference released alongside the EOI and submit proposals to lead or collaborate within the national research clusters.
It added that a press conference would be held in the coming week to provide further details and engagement opportunities for vice-chancellors and research institutions across the country.

NCC Cracks Down: Telcos to Refund Users for Network Disruptions

Nigerian Communications Commission (NCC) has directed Mobile Network Operators (MNOs) to compensate subscribers experiencing poor network service across the country.

The Commission said the directive was part of efforts to ensure that consumers are not made to bear the burden of service failures when operators fall short of required standards.
Under the new regulation, telecom operators will be required to provide compensation directly to affected subscribers for breaches of Quality of Service (QoS) Key Performance Indicators (KPIs).
According to the NCC, the compensation will be issued in the form of airtime credits, calculated based on subscribers’ average usage and their presence within specific Local Government Areas where service disruptions occur.
The Commission emphasised that telecommunications services remain critical to economic activities, social interactions, and access to digital opportunities, noting that poor service delivery negatively impacts productivity and public confidence.
It explained that while regulatory fines have traditionally been used to sanction operators, the new approach prioritises consumer protection and strengthens accountability within the telecommunications sector.
The NCC added that the measure would complement existing efforts to monitor service quality and enforce compliance with performance standards.
In addition, the Commission directed tower companies responsible for telecom infrastructure, such as network masts, to reinvest fines imposed on them into infrastructure upgrades with measurable outcomes.
The regulator reiterated its commitment to ensuring that operators invest in network resilience, expand capacity, and improve infrastructure to meet growing demand.
It also pledged to continue deploying regulatory mechanisms that promote fairness, transparency, and accountability across the industry, while ensuring that subscribers receive the quality of service they deserve.
