Produktbeschreibung

POSITIONING AND LOCATION-BASED ANALYTICS IN 5G AND BEYOND Understand the future of cellular positioning with this introduction The fifth generation (5G) of mobile network technology are revolutionizing numerous aspects of cellular communication. Location information promises to make possible a range of new location-dependent services for end users and providers alike. With the new possibilities of this location technology comes a new demand for location-based analytics, a new paradigm for generating and analyzing dynamic location data for a wide variety of purposes. Positioning and Location-based Analytics in 5G and Beyond introduces the foundational concepts related to network localization, user positioning, and location-based analytics in the context of cutting-edge mobile networks. It includes information on current location-based technologies and their application, and guidance on the future development of location systems beyond 5G. The result is an accessible but rigorous guide to a bold new frontier in cellular technology. Positioning and Location-based Analytics in 5G and Beyond readers will also find: * Contributions from leading researchers and industry professionals * High-level insights into 5G and its future evolution * In-depth coverage of subjects such as positioning enablers, location-aware network management, reference standard architectures, and more Positioning and Location-based Analytics in 5G and Beyond is ideal for researchers and industry professionals with an understanding of network communications and a desire to understand the future of the field.
