✦ Synopsis

Over the Air Measurement for Wireless Communication Systems is a complete and cutting-edge guide to the performance evaluation of wireless systems, such as 5th Generation wireless communications (5G) and beyond, Internet of Things (IoT), Intelligent Connected Vehicle (ICV), wireless sensors, and smart world wireless terminals. The book covers critical specifications for wireless communication systems, including Total Radiated Power (TRP) and Total Isotropic Sensitivity (TIS). Readers are provided with the latest on emerging applications such as massive Multiple-Input Multiple-Output (MIMO) and Intelligent Connected Vehicle Over the Air Measurements (OTA), as well as in-depth knowledge of OTA systems and OTA test and measurement algorithms. This is a useful resource for wireless system managers, antenna and RF engineers, certification and measurement professionals, consultants and researchers, as well as advanced students. It is also suitable for certification specialists, test engineers, and project managers for selecting suitable OTA systems.
