LTE Advanced Pro - Towards the 5G Mobile Network (Hardcover): Frederic Launay, Andre Perez LTE Advanced Pro - Towards the 5G Mobile Network (Hardcover)
Frederic Launay, Andre Perez
R3,765 Discovery Miles 37 650 Ships in 10 - 15 working days

This book presents LTE evolution towards 5G mobile communication and the emergence of new requirements for MBB, MTC and LLC services. As LTE technologies evolve, LTE Advanced Pro dramatically increases cell capacity and user data rates for the MBB unicast service. Such requirements are obtained using full-dimension MIMO, carrier aggregation (on either licensed or unlicensed frequency bands) and dual connectivity. To improve the efficiency of same-content delivery to multiple users, 3GPP proposes a group communications service over LTE and defines mission critical push-to-talk (MCPTT) for dedicated public safety services. Complementary low-cost and low-power modems with enhanced coverage and massive connectivity are emerging. Thus, this book also discusses the need for LTE to support low-rate transmission and high-latency communication for MTC services.

Offering a deeper understanding of today's internet media and the management theory behind it Platforms are everywhere. From social media to chat, streaming, credit cards, and even bookstores, it seems like almost everything can be described as a platform. In The Platform Economy, Marc Steinberg argues that the "platformization" of capitalism has transformed everything, and it is imperative that we have a historically precise, robust understanding of this widespread concept. Taking Japan as the key site for global platformization, Steinberg delves into that nation's unique technological and managerial trajectory, in the process systematically examining every facet of the elusive word platform. Among the untold stories revealed here is that of the 1999 iPhone precursor, the i-mode: the world's first widespread mobile internet platform, which became a blueprint for Apple and Google's later dominance of the mobile market. Steinberg also charts the rise of social gaming giants GREE and Mobage, chat tools KakaoTalk, WeChat, and LINE, and video streaming site Niconico Video, as well as the development of platform theory in Japan, as part of a wider transformation of managerial theory to account for platforms as mediators of cultural life. Analyzing platforms' immense impact on contemporary media such as video streaming, music, and gaming, The Platform Economy fills in neglected parts of the platform story. In narrating the rise and fall of Japanese platforms, and the enduring legacy of Japanese platform theory, this book sheds light on contemporary tech titans like Facebook, Google, Apple, and Netflix, and their platform-mediated transformation of contemporary life-it is essential reading for anyone wanting to understand what capitalism is today and where it is headed.

R4,206 Discovery Miles 42 060 Ships in 10 - 15 working days

Mobile phones are widely viewed as the information and communication technology that holds the most promise for bridging global digital divides. Gendered Power and Mobile Technology uses empirical research to focus on changing intersections between technology, gender and other categories of social and cultural power difference (such as age, race, class, and ethnicity) in the use of mobile communication technologies. Asking how these intersections can inform development discourse, practice, and research, this volume seeks to rectify the lack of attention to the Global South, calling for more sensitivity to the contexts and consequences of mobile phone use. Indeed, drawing on case studies from Ecuador, Ghana, Kenya, Mexico, Peru, Tanzania, and Uganda, this book engages with the intersectionality paradigm to tease out the complexities of using mobile technologies for development purposes. Gendered Power and Mobile Technology will appeal to students and researchers interested in fields such as media studies, development studies, gender and technology, feminist technoscience, anthropology, and sociology.

This includes a set of Radio Access Technologies (RATs), consisting of NR and LTE; with each RAT meeting different aspects of the requirements. The second chapter describes the air interface of NR and LTE side by side. The basic aspects of LTE that NR builds upon are first described, followed by sections on the NR specific technologies, such as carrier/channel, spectrum/duplexing (including SUL), LTE/NR co-existence and new physical layer technologies (including waveform, Polar/LDPC codes, MIMO, and URLLC/mMTC). In all cases the enhancements made relative to LTE are made apparent. The third chapter contains descriptions of NR procedures (IAM/Beam Management/Power control/HARQ), protocols (CP/UP/mobility, including grant-free), and RAN architecture. The fourth chapter includes a detailed discussion related to end-to-end system architecture, and the 5G Core (5GC), network slicing, service continuity, relation to EPC, network virtualization, and edge computing. The fifth and major chapter describes the ITU submission and how NR and LTE meet the 5G requirements in significant detail, from the rapporteur responsible for leading the preparation and evaluation, as well as some field trial results. Engineers, computer scientists and professionals with a passing knowledge of 4G LTE and a comprehensive understanding of the end to end 5G commercial wireless system will find this book to be a valuable asset. Advanced-level students and researchers studying and working in communication engineering, who want to gain an understanding of the 5G system (as well as methodologies to evaluate features and technologies intended to supplement 5G) will also find this book to be a valuable resource.
