The OTA measurement for performances of communication system is required in 5G communication systems. This paper describe the required parameters of OTA measurement defined by 3GPP. In order to measure these parameters, the advantages and limitations of conventional OTA measurement techniques, DFF, NFR, and CATR will be discussed and compared. Traditional CATR can only generate one plane wave by one offset reflector, the brand new T-CATR with toroidal reflector for generating multiple plane waves will also be discussed. |
