A revised edition of the text that offers a comparative introduction to global wireless standards, technologies, and their applications The revised and updated fourth edition of From GSM to LTE-Advanced Pro and 5G: An Introduction to Mobile Networks and Mobile Broadband offers an authoritative guide to the technical descriptions of the various wireless technologies currently in use. The author--a noted expert on the topic--explains the rationale behind their differing mechanisms and implementations while exploring the advantages and limitations of each technology. The fourth edition reflects the significant changes in mobile network technology that have taken place since the third edition was published. The text offers a new chapter on 5G NR that explores its non-standalone and standalone architecture. In the Wi-Fi chapter, additional sections focus on the new WPA3 authentication protocol, the new 802.11ax air interface and protocol extensions like 802.11k and 11v for meshed networks. This important book: Presents the various systems based on the standards, their practical implementation and design assumptions, and their performance and capacity Provides an in-depth analysis of each system in practice Offers an updated edition of the most current changes to mobile network technology Includes questions at the end of each chapter and answers on the accompanying website that make this book ideal for self-study or as course material Written for students and professionals of wireless technologies, the revised fourth edition of From GSM to LTE-Advanced Pro and 5G provides an in-depth review and description of the most current mobile networks and broadband.

Many wireless systems like GSM, GPRS, UMTS, Bluetooth, WLAN or WiMAX offer possibilities to keep people connected while on the move. In this flood of technology and claims that one single resource will serve all our needs, this book seeks to enable readers to examine and understand each technology, and how to utilise several different systems for the best results.

"Communication Systems for the Mobile Information Society" not only contains a technical description of the different wireless systems available today, but also explains the thoughts that are behind the different mechanisms and implementations; not only the 'how' but also the 'why' is in focus. Thus the advantages and also limitations of each technology become apparent.

Provides readers with a solid introduction to major global wireless standards and compares the different wireless technologies and their applications

Describes the different systems based on the standards, their practical implementation and why they were designed the way they are

The performance and capacity of each system in practice is analyzed and explained, accompanied with practical tips on how to discover the functionality of different networks by the readers themselves

Questions at the end of each chapter and answers on the accompanying website make this book ideal for self study or as course material

Illustrated with many realistic examples of how mobile people can stay in touch with other people, the Internet and their corporate intranet

This book is an essential resource for telecommunication engineers, professionals and computer science and electrical engineering students who want to get a thorough end-to-end understandingof the different technical concepts of the systems on the market today.

Extensively updated evaluation of current and future network technologies, applications and devices

This book follows on from its successful predecessor with an introduction to next generation network technologies, mobile devices, voice and multimedia services and the mobile web 2.0. Giving a sound technical introduction to 3GPP wireless systems, this book explains the decisions taken during standardization of the most popular wireless network standards today, LTE, LTE-Advanced and HSPA+. It discusses how these elements strongly influence each other and how network capabilities, available bandwidth, mobile device capabilities and new application concepts will shape the way we communicate in the future. This Second Edition presents a comprehensive and broad-reaching examination of a fast-moving technology which will be a welcome update for researchers and professionals alike.

Key features: Fully updated and expanded to include new sections including VoLTE, the evolution to 4G, mobile Internet access, LTE-Advanced, Wi-Fi security and backhaul for wireless networksDescribes the successful commercialization of Web 2.0 services such as Facebook, and the emergence of app stores, tablets and smartphonesExamines the evolution of mobile devices and operating systems, including ARM and x86 architecture and their application to voice-optimized and multimedia devices

Studienarbeit aus dem Jahr 2010 im Fachbereich Soziologie - Kinder und Jugend, Note: 1,0, Padagogische Hochschule Weingarten, Veranstaltung: Interkulturelle und transkulturelle Padagogik, Sprache: Deutsch, Abstract: Die Emokultur. Was wissen wir eigentlich daruber?" Einer fing an: Sie sind schwarz gekleidet." Ein anderer meinte: Sie schminken sich." Kurzes Uberlegen. Was wissen wir noch?" Naja, ich glaube die Emos sind alle depressiv und ritzen sich. Jedenfalls hab ich das im Fernsehen gesehen." Sicher war sich da aber eigentlich keiner von uns. Sind das nur Vorurteile oder ist es wirklich so? Die Boulevardpresse berichtet jedenfalls oft davon. Jugendliche, die mit sich selbst und der Welt nicht klarkommen. Mit Rasierklingen ritzen sie ihre Arme, sind depressiv und kuscheln miteinander. Manchmal hort es sich schon an wie Textstellen aus Die Leiden des jungen Werther" von Goethe. Immer schwarz gekleidet, schminken sich und lackieren die Fingernagel, ebenfalls alles in schwarz. Klischees uber Klischees. Oder? Wir sind 5 Personen, die eigentlich keine Ahnung hatten, was ein Emo wirklich ist. Welche Musik horen Emos? Gibt es eigentlich viele davon? Sind sie so ahnlich wie Punks, politisch links und haben immer was zu sagen. Meistens gegen alles Oder vielleicht wie Gothics? Also so eine richtige Jugendsubkultur, von der wir einfach noch nichts mitbekommen haben. Oder sind die Emos nur eine Modeerscheinung, die nachstes Jahr jeder vergessen hat? Erfunden von H&M. Oder sind sie wie die Raver der 90er Jahre? Ein Massenphanomen. Tausende von Techno-Fans, die auf den Strassen mit Sonnenblumen und Schnuller um den Hals, tanzend die neue Generation der Jugend einleiten. Eine Generation, die standig auf der Suche nach der endlosen Party ist. Ihr Erbe hat sich jedenfalls bis heute gehalten. Die Mode verschwand wieder. In unserer heutigen Gesellschaft gibt es eine enorme Vielfalt in der Jugendkultur. Daher mussen wir zwischen verschiedenen Jugendsubkulturen unterscheiden
