High-Density and De-Densified Smart Campus Communications

Design, deliver, and implement high-density communications solutions

High-density campus communications are critical in the operation of densely populated airports, stadiums, convention centers, shopping malls, classrooms, hospitals, dense smart cities, and more. They also drive Smart City and Smart Building use cases as High-Density Communications (HDC) become recognized as an essential fourth utility. However, the unique requirements and designs demanded by HDC make implementation challenging.

In High-Density and De-Densified Smart Campus Communications: Technologies, Integration, Implementation and Applications, a team of experienced technology strategists delivers a one-of-a-kind treatment of the requirements, technologies, designs, solutions, and trends associated with HDC. From the functional requirements for HDC and emerging data/Wi-Fi 6/internet access/5G cellular/OTT video, and IoT automation--including pandemic-related de-densification--to the economics of broad deployment of HDC, this book includes coverage of every major issue faced by the professionals responsible for the design, installation, and maintenance of high-density communication networks. It also includes:
_ A thorough introduction to traditional and emerging voice/cellular design for campus applications, including the Distributed Antenna System (DAS)
_ Comprehensive explorations of traditional sensor networks and Internet of Things services approaches
_ Practical discussions of high-density Wi-Fi hotspot connectivity and related technologies, like Wi-Fi 5, Wi-Fi 6, spectrum, IoT, VoWiFi, DASs, microcells issues, and 5G versus Wi-Fi issues
_ In-depth examinations of de-densification, office social distancing, and Ultra-Wideband (UWB) technologies

Perfect for telecommunication researchers and engineers, networking professionals, technology planners, campus administrators, and equipment vendors, High-Density Smart Campus Communications will also earn a place in the libraries of senior undergraduate and graduate students in applied communications technologies.
