5G - the next generation in mobile telephony - is heralded as a huge advance in global connectivity. But the vision is flawed. It is flawed because users will not value the higher data rates that are promised and will not need the higher capacity forecast. It is flawed because technological advances are insufficient to realise the vision and because mobile operators are insufficiently profitable to afford it. Yet it is not in the interests of any of the stakeholders to point this out. They all benefit from the interest, funding and potential that 5G promises. There is an alternative vision where industry focuses on consistent connectivity everywhere rather than ridiculously fast speeds in city centres. This short and easily digested book book explains why the vision of 5G is flawed and sets out a better vision for a connected future. Chapter 1 examines the lessons of history, looking back at the transitions through previous generations and showing what simple extrapolations of trends would predict for 5G. It shows that if previous trends were followed, 5G would become widely deployed in 2022 and deliver realistic end-user data rates of 200Mbits/s and an increase in capacity of around 2x compared to current networks. Chapter 2 examines whether such increases in speed and capacity are needed. It shows that users do not value speeds above those already widely available on 4G. It demonstrates that while data requirements are currently growing rapidly, the rate of growth is slowing and if extrapolated will result in a plateau in data rate requirements around 2027, with little growth in the 5G era. Hence, it concludes that the advances in speed and capacity that 5G might bring are not needed. Chapter 3 considers whether the technology is available to provide such gains. It shows that further capacity improvements are very difficult and likely to be expensive to realise, raising the cost of provision for MNOs. It also suggests that some changes to the core network may have unexpected side-effects of enabling different industry structures, splitting the functions provided by MNOs today across multiple players. Chapter 4 considers industry economics and shows that MNOs are in a position of declining revenues relative to GDP, and poor profitability. Few expect this to change with 5G with the result that investment is highly unattractive. Chapter 5 asks why, if the position is so bleak, that the industry collectively appears so supportive of 5G. It shows that it is not in the interest of any of the key players to cast doubt on a bullish 5G vision and that for some the emergence of 5G is essential to their very survival. Chapter 6 examines the visions set out for 5G in more detail. It shows that they are often over-stated. The collective vision of the MNOs, as set out by the NGMN group is examined in detail and each service is shown to be either deliverable via existing wireless solutions such as 4G, or economically unviable. The chapter shows that few know what 5G actually is. Chapter 7 asks what might transpire in place of the current 5G vision. It suggests that consistent connectivity of around 10Mbits/s everywhere is a more compelling vision and shows how it can be delivered via a mix of 4G and Wi-Fi. It also lays out a possible path for its introduction showing how this could result in seismic changes to the structure of the industry. Chapter 8 looks more broadly at the communications world, considering the impact of regulations, spectrum and broadband access to the home. It shows that regulation is set to maintain the status quo which early chapters have shown to be unsustainable and predicts this will cause further problems for any 5G vision. Chapter 9 summarises the findings of the book, sets out why the current 5G vision is a myth, and discusses what is more likely to transpire.

This unique volume considers the emergence of “Industry 4.0” (i4.0) and the many ways the multifaceted field of Engineering is transforming our ideas and our options around sustainability. It points to emerging technological advances that are facilitating industrial process improvements to artificial intelligence’s promise to help us live “smartly” and manage energy demand. Engineering for a sustainable future is an exploding area of research. This book provides coverage of key case studies from industrial partners such as Ericsson, British Telecom (BT), BMW, Matrixx and research from different UK and international institutions. Examines Smart Engineering Design; Considers how Communication Technologies are developing in the age of i4.0 (from 4G to 6G and beyond); Using interesting case studies from large manufacturers such as BMW to examine Rapid Prototyping and Digital manufacturing; Covers some key issues about Big Data and network security and discusses “Blockchain”; Provides fresh insight into Artificial Intelligence (AI) and Augmented Reality; Discusses global warming and discusses how urban heat islands are having a detrimental impact on the health and wellbeing of inhabitants in major cities; Provides interesting case studies to determine the industry 4.0 (I4.0) readiness of eight Central and Eastern European countries (CEECs).

This book provides a comprehensive overview of the latest research and standardization progress towards the 5th generation (5G) of mobile communications technology and beyond. It covers a wide range of topics from 5G use cases and their requirements, to spectrum, 5G end-to-end (E2E) system architecture including core network (CN), transport network (TN) and radio access network (RAN) architecture, network slicing, security and network management. It further dives into the detailed functional design and the evaluation of different 5G concepts, and provides details on planned trials and pre-commercial deployments across the globe. While the book naturally captures the latest agreements in 3rd Generation Partnership Project (3GPP) New Radio (NR) Release 15, it goes significantly beyond this by describing the likely developments towards the final 5G system that will ultimately utilize a wide range of spectrum bands, address all envisioned 5G use cases, and meet or exceed the International Mobile Telecommunications (IMT) requirements for the year 2020 and beyond (IMT-2020). em style="mso-bidi-font-style: normal;"5G System Design: Architectural and Functional Considerations and Long Term Research is based on the knowledge and consensus from 158 leading researchers and standardization experts from 54 companies or institutes around the globe, representing key mobile network operators, network vendors, academic institutions and regional bodies for 5G. Different from earlier books on 5G, it does not focus on single 5G technology components, but describes the full 5G system design from E2E architecture to detailed functional design, including details on 5G performance, implementation and roll-out.

...a comprehensive overview of the current state of research, theory and practice drawn from the leading scholars and practitioners who have advanced our understanding of mentoring in the workplace... The Handbook of Mentoring at Work; Research, Theory, and Practice, provides a definitive guide that not only informs the field, but also extends it in three critical ways: Chronicles the current state of knowledge of mentoring and identifies important new areas of research: The Handbook begins with offering an extensive, cutting-edge and in-depth review of core topics in mentoring research, such as diversity in mentoring relationships, learning processes in mentoring relationships, formal mentoring, peer mentoring, socialization and mentoring, leadership and mentoring, dysfunctional mentoring, personality and mentoring, and electronic mentoring. Extends the theoretical horizon of mentoring: The theoretical section of the Handbook builds and extends mentoring theory by drawing on a diverse and rich literature of related theories, such as network theory, adult development theory, relational theory, communication theory, personal change theory, work-family theory and theories of emotional intelligence. Builds a bridge between the practice and study of mentoring: The Handbook includes chapters that address not only formal mentoring programs, but also mentoring practices that relate to leadership development programs, diversity programs and international perspectives. The Handbook is a "must-have" reference for understanding the key debates and issues facing mentoring scholars and practitioners, and provides a theory-driven road map to guide future research and practice in the field of mentoring.
