Enabling The 5G Intelligent Edge: How White Box Network Solutions Help Drive AIoT Innovation in the 5G Era
The world is at a technology inflection point that hasn’t been seen since the rise of the Internet, and 5G is paving the path. Recent advancements in machine learning and the internet of things (IoT), paired with new network technologies, 5G New Radio (5G NR), disaggregation, edge computing, and open industry standards, are all coming together – leading to a new era that will be driven by the AIoT, or the Artificial Intelligence of Things. Ripples of this transformation will be felt across many industries, impacting business models and operations. Industry 4.0, what is expected to be the next industrial revolution, is one outcome.
AI-enabled private 5G networks will shepherd in an era of connected machines and robotic processes working autonomously to deliver system-wide automated processing control. These systems will have the capacity to ‘learn’ to optimize productivity – allowing businesses to become more efficient and agile. This is expected to significantly improve productivity and output. In fact, it is estimated that by 2030, the manufacturing sector could add $400 billion to $650 billion to the global GDP by leveraging the benefits of 5G, and private networks are quickly becoming a new avenue for growth for service providers around the globe. Private LTE and 5G networks generated $4.7 billion in revenue in 2020. That number is expected to be $8 billion by the end of 2023. (source: SNS Telecom and IT)
The factory of the future will be more automated and efficient than today, and white box hardware is an important component in achieving this goal. The concept of white-box hardware has been around for nearly a decade but has really taken off in the networking space in the recent years due to the broader adoption of network functions virtualization (NFV). A white-box infrastructure is based on interoperable, programmable, off-the-shelf equipment designed to provide support for web-scale, could-native, virtualized network architectures - delivering greater flexibility and agility from the core to the edge. This paper addresses the reasons, challenges, and benefits of service providers and enterprises adopting a white box edge approach to optimize operations and generate new revenue.
5G – A Key Enabler for Industry 4.0 and AIoT
Industry 4.0 brings together various advances in technology – but there remains an issue with connectivity. Even the most advanced factories still rely upon traditional fiber-based or Wi-Fi networks. In a fiber-based environment, there is no flexibility for supporting an increasing number of mobilen devices and sensors, and in a traditional wi-fi environment, the growing number of business-critical connections contributes to interference, congestion and security concerns that are difficult to manage in advanced industrial environments.
When paired with 5G, AIoT has the potential to transform businesses across industries, creating a new economy that will power the fourth industrial revolution. One that is driven by machine learning and automated decision making, connectivity, and the exchange of data. This opens the door to a new generation of smart factories, smart logistics, smart transportation, smart energy grids, smart cities, and more.
5G New Radio
In contrast to previous generations, 5G New Radio (5G NR) is built for business. It is a transformative technology that enables greater bandwidth and lower latency. Plus, the added security and reliability benefits meet the needs of mission-critical applications. Previous mobile communication technologies were designed primarily for mobile handsets. But as millions of new IoT 5G enabled chipsets, modules and other connected devices come into the market, the focus will go far beyond these personal devices and into a world of connected ‘things’ made smarter through artificial intelligence. A world of AIoT fueled by 5G.
3GPP has defined three initial 5G use cases, which will help power an AIoT enabled Industry 4.0:
- Ultra-reliable low latency communication (URLLC) - for real-time communications between machines
- Enhanced mobile broadband (eMBB) - greater bandwidth and support for a higher number of connected devices and sensors that generate more data traffic
- Massive machine-type communications (mMTC) - low power connections for longer battery life, enabling support for massive numbers of IoT sensors and devices.
Private 5G Networks
Private 5G networks have been designed to deliver businesses with ultra-reliable, low-latency mobile connections that will power new capabilities - from predictive maintenance, autonomous machines, and factory robotics to ultra-high definition video analytics that will enable many different use cases across industry verticals.
Today, there are different deployment options and business models for private 5G networks, each with their own level of mobile network operator (MNO) engagement:
Option A: An enterprise builds its own 5G network with spectrum that they have purchased outright or leased from a mobile service provider. Some countries have reserved unlicensed or lightly licensed bands, such as the Citizens Broadband Radio Service (CBRS), to support this capability.
Option B: A MNO builds and operates an on-premises private 5G network for the enterprise and provides integration with its public network if required.
Option C: A MNO builds a public 5G network and provides a dedicated network slice that meets the enterprise’s specific SLA requirements.
White Box Hardware and 5G
With these new business models in mind, service providers are investing in virtualizing their mobile networks, creating the agile, automated, cloud-native environment that 5G needs to succeed. An open architecture that utilizes common industry standards, supported by the O-RAN ALLIANCE, the Telecom Infra Project (TIP), and others, to fully realize the 5G vision.
Since its foundation in 2018, the O-RAN ALLIANCE has promoted the use of white-box hardware to reduce the cost of 5G deployments. Up until now, mobile networks have been relatively closed ecosystems. By opening the Radio Access Network (RAN) to new cloud and IoT players through a standardized, interoperable, multi-vendor environment, innovative services and applications can be deployed at the edge that generate new revenue streams. Adopting a white-box strategy reinforces this approach – building an open and agile foundation that will allow operators to take advantage of economies of scale and encourage the creation of an innovative and competitive ecosystem that is ready to adopt next-generation cloud-native architectures.
The white box transformation is also happening at the enterprise edge (figure 1) with virtual functions such as SD-WAN being deployed on commercial-off-the-shelf appliances or universal Customer Premises Equipment (uCPE), setting the scene to deliver a broader range of premium 5G enterprise services. As introduced before, 5G technology enhancements have put the spotlight on private 5G networks as key smart manufacturing and AIoT enablers, providing a secure wireless connectivity solution for AI, VR and AR that heavily rely on 4K/8K UHD video as a main source of information. NFV and software-defined networking (SDN), along with the definition of O-RAN standards and the use of white box infrastructure, are democratizing mobile network technology, enabling 5G Stand Alone (5G SA), low-footprint solutions that are viable for enterprise deployment.
Still, while building this new open and intelligent 5G edge, a gap needs to be addressed so that the benefits of Industrial 5G and AIoT can be fully realized. This is where the operational technology (OT) layer, which is defined as the equipment and industrial systems within a production environment, needs to “talk” to the information technology (IT) and communication technology (CT) layers. The operational technology layer needs to integrate seamlessly with the IT and CT layers to deliver on the promise of the intelligent, autonomous, AI-driven factory of the future. Again, white-box solutions can play a key role to accelerate digital transformation and mend this gap by enabling an open architecture that extends network intelligence all the way to the factory floor, over a consistent white-box infrastructure that can reliably execute mission-critical applications anywhere in the network. Private 5G solutions deployed following this approach allow for a lighter, more flexible and future-proof communications infrastructure that can be managed as another enterprise IT system.
White Box Benefits
Overall, virtual, and open infrastructure solutions based on white box hardware opens the network to innovation, optimizes infrastructure costs and lowers barriers to entry. The disaggregation of software and hardware is at the foundation of these capabilities. Below are the benefits that can be achieved when a carefully considered, strategic approach is taken:
The right white box approach can advance the standardization of telco infrastructure, making private 5G networks more efficient, flexible, and easier to implement with commercial, off-the-shelf solutions.
A More Agile Infrastructure
An intelligent, virtualized network edge infrastructure based on white box hardware can ensure greater network agility by supporting a cloud-native architecture that enables web-scale open compute, networking, and storage.
The interoperability of white box hardware can provide second-sourcing protection, reducing supply chain risks, and enabling a more competitive ecosystem that benefits both vendors and operators.
Challenges at the Edge
Today, there is widespread agreement amongst operators that edge computing and core 5G network functions will need to be tightly integrated with and powered by public and private clouds, which is especially true for Industrial AIoT. As mentioned previously, the O-RAN ALLIANCE, 3GPP, and many operators worldwide understand the advantages and are committed to driving these efforts forward
But implementing a scale-out white-box strategy across the network is a challenging task as there is no one-size-fits-all option when it comes to the edge. White box hardware is not all created equally. At its best, it can deliver high availability, redundancy, and remote management; supporting intelligent manufacturing by bridging the critical operational technology gap mentioned earlier. With the arrival of edge computing, the right hardware platform must be chosen based not just on what function it will perform, but also on where and under what conditions, to guarantee sustained operations and avoid costly downtime.
Key Challenges to Consider:
- Reliability – Reliability and sustained operations is a top priority when deploying network equipment that supports mission and business critical applications. Painstakingly designed hardware that has built in redundancy and high availability reduces costly downtime and service interventions. Advanced remote management, such as fail-safe upgrades, is another key consideration that can greatly reduce operational expenses.
- Performance – The data tsunami brought by 5G and AIoT will require higher computing power to be moved closer to subscribers at the edge of the network. In addition, vRAN brings the challenge of deploying baseband virtual Distributed Unit (vDU) functions at the edge on white-box base station infrastructure that will also require higher performance to support 5G NR.
- Energy Efficiency – Edge computing moves computing resources outside of the datacenter to remote locations with strict energy and space constrains. To ensure maximum energy savings at the edge, performance-per-watt should be a primary consideration of any white box strategy, along with hardware acceleration and the ability to maximize density. Hardware consolidation to optimize resources usage will also be critical.
- Environmental – Certain environments, such as heat, cold or dust, can result in poor performance, or even failure. As mentioned before, bringing high performance hardware to remote locations means having to deal with harsh environments far from datacenter-controlled conditions. Maintainability is also a consideration. Can the system be easily accessed, maintained, and serviced - or are there limitations? It is important to select hardware that is designed to meet these specific edge needs to assure continued high-performance operations.
- Integration – Network disaggregation and virtualization opens the market and optimizes infrastructure costs. However, this new multi-vendor scenario creates new risks in having to integrate pieces from different sources without jeopardizing performance, security or reliability. An open, programmable, off-the-shelf white box approach requires strong eco-system collaboration and pre-validated configurations to achieve streamlined deployments. In the end, this saves time and money, while enabling more agile, future-proof, open solutions.
