The 5G network

The Next Generation Mobile Networks (NGMN) describes 5G as “an end-to-end ecosystem” that is expected to “enable a fully mobile and connected society”. The most prominent include fixed-wireless access, ultra-reliable low-latency (high volume of data messages with minimal delay) communications, enhanced mobile broadband and massive . The effective implementation of the 5G vision could translate into driverless cars, virtual or augmented reality experiences, , robotics and . However, the proposed 5G use cases rely on , pertaining notably to latency, throughput, reliability and transmission character.

To address all of these use cases, networks need to become more flexible. This is achieved through , a form of virtual network architecture built on common shared physical infrastructure. Each network slice consists of an independent set of logical (software-based) network functions that support the requirements of the specific use case. For instance, the driverless car will rely on vehicle-to-anything (V2X) communication, which requires low latency but not necessarily a high throughput, while a streaming service being watched while the car is in motion will require a high throughput and is susceptible to latency. are thus employed to optimise the use of the physical network. This can also enhance , by isolating attacks on the network slice, given that security poses the biggest challenge as these networks evolve, according to Ray Lahoud, Chief Operating Officer at Allstream.

Network slicing relies on and . SDN the data and control planes, which, along with the management plane, constitute the three basic components of a telecommunications . By removing the control plane from network hardware and implementing it in software, SDN enables programmatic access, making network administration much more flexible.ÌęWhile SDN enables network slicing, the NFV architecture is employed to and its constituent resources, and orchestrating their allocation to realize the virtual network functions (VNFs) and network service.Ìę In a nutshell, NFV provides the ‘what’ (virtualization architecture) and SDN provides the ‘how’ (Application Programming Interfaces and control protocols) to .

SDNs can be deployed today leveraging existing Application Programming Interfaces ().Ìę APIs constitute a point of interaction between a number of systems. From the users’ point of view, APIs allow them to complete the action . APIs speed up the communication between apps and platforms, allowing service providers to deploy innovative high-quality services by bypassing one-on-one, costly and time-consuming proprietary integration. As Ibrahim Gedeon, Chief Technology Officer at Telus, described it, before embarking on any technological transformation journey we need to “speak the same language to talk about innovation”, which in turn translates to the need for a .

Network softwarization is paving the way towards X-as-a-Service (XaaS). XaaS refers to the concept that , including the functions that control a telecom network, notably Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS). With these resources made available by , telecom service providers maintain a major influence over the services they buy, while offloading the costs of Research and Development (R&D), security and optimization. XaaS extends , with Transportation-as-a-Service offered by Uber and Lyft, Grocery-as-a-Service by Safeway and Whole Foods, and Accommodation-as-a-Service by Airbnb.

New Business Models

According to the NGMN , 5G is expected to “empower value creation towards customers and partners, through existing and emerging use cases, delivered with consistent experience, and enabled by sustainable business models.” Essentially, this means that telcos will start shifting from their traditional Business-to-Customer (B2C) to a Business-to-Business (B2B) business model, by opening their networks to other stakeholders and allowing the latter to reuse their capabilities in order to deliver new services to customers.

Communication Service Providers (CSPs) can monetize new data-intensive Over-the-Top (OTT) services through partnerships with OTT providers or by charging them for access to their networks. In fact, operators have already started to leverage to deliver packaged services to end users. OTT players are expected to deliver more applications that require higher quality, lower latency, and other service enhancing capabilities, namely proximity, location, quality of service (QoS), authentication, on demand and in a highly flexible and programmable way.

In addition, as James Buchanan, Senior VP & General Manager of Ensemble ADVA Optical Networking, framed it, monetization of data is key to proving that it is worth investing in 5G. While telcos are now relying only on data to improve customer experience and QoS, with 5G network services combined with IoT and AI, new business models of monetization will arise, namely . New business opportunities will thus emerge for telcos not only through data monetization but also from the value delivered to enterprises via application and network intelligence layers.

IPR, RnD and Investment in 5G

The realization of the 5G vision, especially in terms of IoT-related applications, will require extensive R&D and investment. Robust intellectual property protection is an to this end. ÌęBased on the NGMN , the IP based business objective is to make 5G access affordable for all types of devices. The proposed NGMN recommendations include improving 5G Standard Essential Patent (SEP) Declarations, establishing Independent 5G SEPAssessments, and exploring and establishing Patent Pool licensing for 5G. All industry partners are expected to develop implementation plans for each of these recommendations.

Overall, this panel’s speakers strongly agreed on the fact that the 5G endeavor cannot be taken exclusively on by the private sector. This was consequently addressed by the Honourable Navdeep Bains, PC, MP, Minister of Innovation, Science and Economic Development in his , during which he announced the launch of ,Ìę, the Evolution of Networked Services through a Corridor in QuĂ©bec and Ontario for Research and Innovation, which is a 3P between the governments of Ontario and Quebec and private sector partners. Minster Bains described ENCQOR as “a 5G test bed that will advance the development of 5G networking solutions and next-generation technologies and applications”. In addition, he proclaimed the launch of two consultations regarding 5G deployment, one of which pertains to the . Based on the aforementioned, the plan toward the 5G seems clearly drafted and in line with the telecom industry’s mantra of “flexibility, scalability and cost”, as epitomized by Mr. Lahoud.

All things smartened up

Ìę5G is the next generation of wireless mobile networks. The speakers highlighted that 5G networks are primarily designed for increasing capacity and enhancing connectivity while operating at much lower latency values. These ultrafast 5G airwaves promise to through the sharing of information—as buildings, cars, people, and a myriad of devices will be able to communicate with each other. The new technology promises to further enhance the users’ experience with smart devices, smart cars, and smart homes. In addition, 5G networks will allow emerging technologies to operate at a much larger scale.

From connecting people to connecting things in real time

ÌęFor example, the panel on 5G networks remarked that, due to the myriad of new capabilities and disruptive applications made available using 5G wireless networks, virtually all industries will experience important changes in how they work and cooperate with one another. Industries will leverage real-time connectivity to the benefit of both consumers and businesses. New capabilities will allow segments of industries to experience real-time economic data, offering the potential to prompt the . To enable all of these features, 5G network communications will increasingly rely on artificial intelligence (“AI”) and big data to build new applications and create more services. As a result, interested parties will have to be attentive as a new regulatory landscape may develop to accommodate the demands of this increased data sharing reality.

How does society become 5G ready?

ÌęIn addressing this question, speakers at CTS 2018 remarked that putting the new technology to use will require several regulatory and policy discussions. Among other challenges, there will be massive amounts of data that can be quickly collected, mobilized, and exchanged across 5G networks. In the commercial and government space, several jurisdictions have engaged in devising regulatory frameworks for the deployment of the new technology (see examples and ).

Canadian policy makers know that this is an industry that needs investment as well as a modern regulatory landscape across municipal, provincial, and federal levels of government. For example, in his , the Honourable , the federal Minister of Innovation, Science and Economic Development, announced that the Government of Canada will be launching two consultationsÌę to support 5G deployment:Ìęthe government is to add an additional 1GHz of millimetre spectrum to support 5G and is beginning a in advance of the 3500 MHz auction.Ìę Minister Bains also discussed an initiative through a Canada-QuĂ©bec-Ontario partnership, (“ENCQOR”),Ìęwhich he described as “a 5G test bed that will advance the development of 5G networking solutions and next-generation technologies and applications”.

Other countries, such as the are taking a great leap towards leadership in the manufacture and operation of network infrastructure. In Canada, industry operators and other stakeholders are well positioned to develop relationships with different levels of the government with a view to speeding up the process of creating standards and laying out best practices for the operation of 5G networks.

Bottom line

5G networks promises innovation, disruption, as well as policy and regulatory discussions. Industry operators and other stakeholders should be attentive to the new opportunities arising from 5G networks, but they should also stay abreast of the impact the Canadian regulatory landscape may have in the industry — particularly by virtue of the challenges that may arise from the vastness amount of data that will be quickly collected, mobilized, and exchanged across 5G networks.
