The advent of constant internet connectivity and mobile communication have transformed the way that many businesses and organisations function. There has been a focus upon the technological aspects and opportunities. This book takes a look into the future at the human aspects of mobile technology in terms of the ways that people will work and communicate in the mobile marketplace.

Fifth-generation cellular radio access networks are currently being standardized as 5G New Radio (NR). The primary objectives of 5G NR are to provide enhanced mobile broadband (eMBB) and ultra-reliable low latency communication (URLLC) capabilities. This innovative resource analyzes these applications in detail to help readers understand how the flexible design of NR makes it suitable for a wide range of use cases and applications. The rationale behind the design decisions made during the NR standardization process are explored. Readers will be able to understand the performance limits of NR when applied to non-eMBB scenarios and how NR compares to 4G and IEEE 802.x connectivity solutions for such scenarios. The main features of 5G phase 2 are explored, as well as the use cases that can be addressed by 5G phase 2. The mathematical models are included to help explain the future evolution of NR in Release 16 and beyond. This is the only book that describes both the standards features of NR and the mathematical models/open research issues for 5G, appealing to both industry practitioners and academic researchers.

A timely addition to the understanding of IMT-Advanced, this book places particular emphasis on the new areas which IMT-Advanced technologies rely on compared with their predecessors. These latest areas include Radio Resource Management, Carrier Aggregation, improved MIMO support and Relaying. Each technique is thoroughly described and illustrated before being surveyed in context of the LTE-Advanced standards. The book also presents state-of-the-art information on the different aspects of the work of standardization bodies (such as 3GPP and IEEE), making global links between them. Explores the latest research innovations to assess the future of the LTE standard Covers the latest research techniques for beyond IMT-Advanced such as Coordinated multi-point systems (CoMP), Network Coding, Device-to-Device and Spectrum Sharing Contains key information for researchers from academia and industry, engineers, regulators and decision makers working on LTE-Advanced and beyond

This book describes the concept of a Software Defined Mobile Network (SDMN), which will impact the network architecture of current LTE (3GPP) networks. SDN will also open up new opportunities for traffic, resource and mobility management, as well as impose new challenges on network security. Therefore, the book addresses the main affected areas such as traffic, resource and mobility management, virtualized traffics transportation, network management, network security and techno economic concepts. Moreover, a complete introduction to SDN and SDMN concepts. Furthermore, the reader will be introduced to cutting-edge knowledge in areas such as network virtualization, as well as SDN concepts relevant to next generation mobile networks. Finally, by the end of the book the reader will be familiar with the feasibility and opportunities of SDMN concepts, and will be able to evaluate the limits of performance and scalability of these new technologies while applying them to mobile broadb and networks.

In leicht verständlichem Stil erläutern die Autoren dieses Buches Anforderungen an Multiple-Access-Protokolle für den Mobilfunk. Zu Beginn werden zellulare Kommunikationssysteme der 2. und 3. Generation eingeführt. Ausführlich beschrieben werden dann MA-Protokolle für paketorientierte zellulare Systeme. Ein großer Teil der vorgestellten Resultate stammt aus eigenen Forschungsarbeiten der Autoren, u.a. zur Verbesserung der Protokolle und zur Modellierung der physikalischen OSI-Schicht.

This anthology deals with the complexity, variety and experience of all the forms of mobility we witness today in Sub-Saharan Africa. Three sets of issues are being discussed. This book intends to turn the whole notion of mobility as a supposedly rupturing phenomenon on its head, emphasizing that rather through travelling connections are established and continuity is experienced. We are challenged to delve into the traveller's mind, to think and follow their multi-spatial livelihoods and to explore what it means to people if they move in a variety of spaces.

Mobile communications users are demanding increased reliability, functionality, and accessibility; they want "always on" access to voice, e-mail, text, and multimedia services as they roam from home to auto to office to outdoor/indoor locations. In addition, there is an increasing deamnd to replace separate landline/mobile telephones with a single handset that can be used wherever its owner might be. Answering those customer needs, fixed/mobile convergence (FMC) marries the mobility provided by cellular networks with the extended connectivity provided by 802.11-based WiFi services and integrates them with landline networks using a single handset.This book provides the theoretical and practical background necessary to successfully plan, develop, and deploy effective FMC networks. This book discusses the various 802.11 and VoIP protocols used in FMC networks, open and proprietary communications protocols, integration of FMC networks to wired telephone networks, mobilizing applications such as text messaging and video, security issues, mobile handset requirements for FMC networks, and the administration/management of FMC networks. Special attention is given to selecting appropriate components for FMC, and numerous case histories and examples from the author's experience are provided.This book is an essential tutorial and reference for any RF/wireless, communications, and networking professional who will work with the next generation of wireless networks. - Describes how to develop, deploy, and manage networks that seamlessly combine landline, cellular, and WiFi networks into one converged communications network - Thorough coverage of various 802.11 and voice over internet protocol (VoIP) standards and how they impact integration with cellular networks - Discusses security considerations and how to successfully manage converged networks - Includes numerous case histories and examples from the author's experience---this is not a purely theoretical treatment of the subject!
