  4g mobile communication: Fundamentals of Cellular Network Planning and Optimisation Ajay R. Mishra, 2004-11-19 “By 2008, some 2 billion people will be using mobile phones and devices, in many cases to access advanced data services. Against this backdrop, the need for efficient and effective network design will be critical to the success of increasingly complex mobile networks.” Simon Beresford-Wylie (SVP, Nokia Networks) With the complexity of the cellular networks increasing day by day, a deeper understanding of the design and performance of end-to-end cellular networks is required. Moreover, all the types of networks from 2G-2.5G-3G seem to co-exist. Fundamentals of Cellular Network Planning and Optimisation covers end-to-end network planning and optimisation aspects from second generation GSM to third generation WCDMA networks including GPRS and EDGE networks. All the sub-systems of the network i.e. radio network, transmission network and core network have been covered with focus on both practical and theoretical issues. By bringing all these concepts under one cover, this book becomes essential reading for the network design engineers working either with cellular service vendors or operators, experts/scientists working on end-to-end issues and undergraduate/post-graduate students. Key Highlights: Distinctly divided into four parts: 2G (GSM), 2.5G (GPRS & EDGE), 3G (WCDMA) and introduction to 4G (OFDM, ALL-IP, WLAN Overview) respectively Each part focuses on the radio, transmission and core networks. Concentrates on cellular network planning process and explains the underlying principles behind the planning and optimizing of the cellular networks. The text will serve as a handbook for anyone engaged in the study, design, deployment and business of cellular networks.
  4g mobile communication: Cyber Security: The Lifeline of Information and Communication Technology Ramjee Prasad, Vandana Rohokale, 2019-10-17 This book discusses a broad range of cyber security issues, addressing global concerns regarding cyber security in the modern era. The growth of Information and Communication Technology (ICT) and the prevalence of mobile devices make cyber security a highly topical and relevant issue. The transition from 4G to 5G mobile communication, while bringing convenience, also means cyber threats are growing exponentially. This book discusses a variety of problems and solutions including: • Internet of things and Machine to Machine Communication; • Infected networks such as Botnets; • Social media and networking; • Cyber Security for Smart Devices and Smart Grid • Blockchain Technology and • Artificial Intelligence for Cyber Security Given its scope, the book offers a valuable asset for cyber security researchers, as well as industry professionals, academics, and students.

  4g mobile communication: Wireless Communication Mainak Chowdhury, Arumita Biswas, 2017-01-16 This book provides extensive coverage of fundamental concepts of wireless communication, including coverage of recent developments and applications in wireless systems.
  4g mobile communication: Cellular Communication Networks and Standards Wei Jiang, Bin Han, 2024-07-12 This textbook provides a comprehensive review of the evolution of mobile communications and networking from the birth of cellular networks to the forthcoming sixth-generation mobile communications, which is envisioned to be commercially deployed first in 2030. New students who are coming to wireless communications/electrical engineering/computer networking/telecommunications and network engineering can benefit from this book by quickly grasping the whole history of cellular networks, understanding its trends. This tutorial styled textbook provides a comprehensive overview, but also provides details of the system design aspects of the various cellular generations up to 6G and how they build on each other. The book also gives the student an overview of different cellular generations’ motivations, core technologies, architecture, key performance indicators, killer applications, market drivers, and the general/main features of each. The authors capture the big picture and fundamental drivers of wireless communication technologies, and then motivate students to understand the importance of learning related subjects such as electromagnetics theory, antenna design, analog and digital circuits, signal processing, Internet protocols, artificial intelligence, etc. The book features homework questions and case studies throughout.
