摘要

根据工业和信息化部针对5GNR 2 600 MHz基站无用发射OTA测试项规定的较为严格的试验网标准要求，针对不同的OTA场地包括远场、紧缩场、近场、动态波束紧缩场等环境以及其他的关键因素进行了实测对比分析，并给出能够通过测试的环境建议。

Abstract

Based on the strict unwanted spurious emission OTA requirements of China local regulation for 5G 2 600 MHz Base Station

the path loss of the different chambers including far field

CATR (compact antenna test range)

near field

DBFC (dynamic beam forming compact range chamber) and other key factors were presented and analyzed according to the measured data.The compared results in different test environment were also shown and the suggestion for passing the test were given.
