Channel sounder verification ensures that participants measure and report channel characteristics that are due to the environment as opposed to measurement artifacts arising from the use of a suboptimal configuration, from nonidealities in the sounder hardware, or from errors in analysis and/or postprocessing. The participants in the 5G mmWave Channel Model Alliance have established a channel sounder verification program. The program allows labs to compare their measured, processed data to theory or to an artifact having known characteristics. Three types of verification are illustrated: “in-situ,” “controlled condition,” and “comparison-to-reference” verification.
