    Default Wireless Localization Techniques

    Xiaohua Tian, Xinyu Tong, Xinbing Wang, "Wireless Localization Techniques"
    English | 2023 | ISBN-13: 978-3-031-21177-5 | 378 pages | PDF | 15.8 MB

    This book first presents a systematic theoretical study of wireless localization techniques. Then, guided by the theoretical results, the authors provide design approaches for improving the performance of localization systems and making the deployment of the systems more convenient. The book aims to address the following issues: how reliable the wireless localization system can be; how the system can scale up with the number of users to be served; how to make key design decisions in implementing the system; and how to mitigate human efforts in deploying the wireless localization system. The book is relevant for researchers, academics, and students interested in wireless localization technology.

    Location service is a prerequisite for numerous IoT applications. While most modern mobile devices are equipped with global navigation satellite system (GNSS) receivers, the satellite system-based location service could be unavailable in certain circumstances, for example, in indoor spaces and "urban canyon" areas, where the satellite signals could be blocked by walls and buildings. It is, therefore, necessary to perform localization with other technical means, which are supposed to meet the following needs: (1) universality - can use commercial off-the-shelf (COTS) devices for localization without hardware modification; (2) effectiveness - can provide services with certain accuracy and reliability; (3) deployability - can be easily deployed with existing infrastructure and limited investments.

    Wireless localization can be a very appropriate candidate solution, which estimates a wireless terminal's location by analyzing features of wireless communication signals, such as Wi-Fi, LTE, and BLE. This technique has been attracting interest from both academia and industry since the past decades; however, most of the research work has been conducted empirically, that is, observing experimental results and phenomena, then coming up with a new idea, and then verifying the new idea with experiments again. A systematic theoretical study has been long pending. Answers to some fundamental issues of the wireless localization technique are still unknown.
