5G Over-the-Air Measurement Challenges: Overview

Abstract

Over-the-air (OTA) measurements are the standardized methods to evaluate radio performance in wireless systems. EMC issues such as interference and receiver desensitization are important factors. In this paper, OTA measurement challenges in the upcoming fiftth generation (5G) wireless systems are overviewed. Several key technologies that could be widely used in the 5G OTA measurements are discussed, including near-field to far-field transformation, anechoic chamber absorbers, and sampling antennas. The most important devices under test (DUT) for 5G OTA are chip sets, user equipment, and active array systems. The OTA test challenges for certification, research and development, and mass production for these DUTs are introduced.
