Comprehensive Handbook Demystifies 5G for Technical and Business Professionals in Mobile Telecommunication Fields

Much is being said regarding the possibilities and capabilities of the emerging 5G technology, as the evolution towards 5G promises to transform entire industries and many aspects of our society. 5G for the Connected World offers a comprehensive technical overview that telecommunication professionals need to understand and take advantage of these developments.

The book offers a wide-ranging coverage of the technical aspects of 5G (with special consideration of the 3GPP Release 15 content), how it enables new services and how it differs from LTE. This includes information on potential use cases, aspects of radio and core networks, spectrum considerations and the services primarily driving 5G development and deployment.

The text also looks at 5G in relation to the Internet of Things, machine to machine communication and technical enablers such as LTE-M, NB-IoT and EC-GSM. Additional chapters discuss new business models for telecommunication service providers and vertical industries as a result of introducing 5G and strategies for staying ahead of the curve. Other topics include:

• Key features of the new 5G radio such as descriptions of new waveforms, massive MIMO and beamforming technologies as well as spectrum considerations for 5G radio regarding all possible bands
• Drivers, motivations and overview of the new 5G system – especially RAN architecture and technology enablers (e.g. service-based architecture, compute-storage split and network exposure) for native cloud deployments
• Mobile edge computing, Non-3GPP access, Fixed-Mobile Convergence
• Detailed overview of mobility management, session management and Quality of Service frameworks
• 5G security vision and architecture
• Ultra-low latency and high reliability use cases and enablers, challenges and requirements (e.g. remote control, industrial automation, public safety and V2X communication)
• An outline of the requirements and challenges imposed by massive numbers of devices connected to cellular networks

While some familiarity with the basics of 3GPP networks is helpful, 5G for the Connected World is intended for a variety of readers. It will prove a useful guide for telecommunication professionals, standardization experts, network operators, application developers and business analysts (or students working in these fields) as well as infrastructure and device vendors looking to develop and integrate 5G into their products, and to deploy 5G radio and core networks.

1.1 Drivers for 5G

Main drivers for the evolution of mobile networks in the past were mobile voice (2G/3G/Voice over Long Term Evolution [VoLTE]), messaging (Short Messaging Service [SMS], WhatsApp) and Internet access (Wideband Code Division Multiple Access [WCDMA], High Speed Packet Access [HSPA], Long Term Evolution [LTE]) whenever and wherever needed. Focus was on end consumers equipped with traditional handsets or smartphones.

Consumer demand continues to be insatiable with an ever growing appetite for the bandwidth that is needed for 4K and 8K video streaming, augmented reality (AR) and virtual reality (VR), among other use cases. On the same token, operators want the network to be “better, faster and cheaper” without compromising any of these three elements.

The biggest difference between 5G and previous “Gs” is the diversity of applications that 5G networks need to support. Objects ranging from cars and factory machines, appliances to watches and apparel, will learn to organize themselves to fulfill our needs by automatically adapting to our behavior, environment or business processes. New use cases will arise, many not yet conceived, creating novel business models. 5G connectivity will impact the following areas:

• Real world mobility. The way we travel and experience our environment;
• Virtual mobility. The way we can control remote environments;
• High performance infrastructure. The way the infrastructure supports us;
• 4th Industrial Revolution. The way we produce and provide goods.

We already have indicators about these long‐term trends and disruptions and they are not only driven by the Internet and the telecommunication industry but by a multitude of different industries. 5G will be the platform enabling growth in many of these industries; the IT, car, entertainment, agriculture, tourism and manufacturing industries. 5G will connect the factory of the future and help to create a fully automated and flexible production system. It will also be the enabler of a superefficient infrastructure that saves resources.

Smartphones are becoming more and more a commodity which means that consumers will differentiate themselves increasingly with new gadgets such as VR devices, connected cars and devices for connected health.

With the decline or at least flattened Average Revenue Per User/Average Revenue Per Device (ARPU/ARPD) in many markets worldwide (typical ARPU is around $30 per month, while ARPD is not more than $3 per month) the telecom industry is more and more considering new revenue streams besides traditional business models. This is where we see new business drivers and requirements, from vertical industries, the Internet of Things (IoT) and the digital society. In the past, the main driver for the mobile industry was connecting people, in the future it is about the “connected world” meaning connecting everyone and everything at any time. This will create new and additional revenue streams for Mobile Network Operators (MNOs). Connecting “things” like cars (e.g. 125 million vehicles to be connected by 2022), robots, meters, medical machines bring new challenges to the next generation of mobile networks. To name only a some of them:

• Ubiquitous, pervasively ultra‐fast connectivity;
• Resilient and secure networks;
• Massive radio resources and ultra‐dense networks; and
• Instantaneous connectivity.

Vertical industries and applications do have very diverse requirements with regards to throughput, latency, reliability, number of connections, security and revenue (see Figure 1.1).

This requires a highly flexible architecture of the new generation of mobile networks, on radio and core network side, as well as at the transport. Flexibility also includes a high ...
