Design and implement 6G-enabled smart city infrastructure sustainably Deploying 6G in urban environments demands interdisciplinary knowledge spanning network architecture, AI-enabled cellular systems, and sustainability. 6G Wireless Communication Systems and Infrastructures in Smart Cities, provides a structured technical guide organized across three parts covering 6G technology fundamentals, real-world applications, and detailed case studies that move from design principles to practical deployment. Organized into sections on 6G technology, applications, and case studies, this book addresses network architecture advances, AI-enabled cellular networks, and legacy system integration, with application including healthcare, transportation, autonomous vehicles, vehicular communications, and IoT-based agriculture. Case studies examine 6G-enabled public safety scenarios including system requirements, evaluation frameworks, and network slicing. Readers will also find: Traffic and congestion management strategies using autonomous vehicles and vehicular communications designed to reduce emissions in urban environmentsFarming management technology coverage showing how to utilize IoT for resource management in agricultural and rural contextsPractical frameworks for integrating new and legacy systems with infrastructural design and implementation considerations for smart citiesCoverage of energy resources, environmental management, and sustainability considerations aligned with smart city planning and deployment goalsSuitable for researchers and graduate students in renewable energy, environmental engineering, and communication technologies, this book will also appeal to industry professionals, policy analysts, and decision makers for planning and deploying 6G-enabled smart city infrastructure.
