YD/T 6778-20265G digital cellular mobile telecommunication network - Test method for OTA test system based on compact antenna test range for Sub6GHz gNB equipment (English PDF)

YD/T 6778-2026 is the English-translated version of 5G数字蜂窝移动通信网 6GHz以下频段基站设备基于紧缩场OTA测试系统的测试方法.

The document gives the basic configuration of an over-the-air (OTA) test system based on a compact antenna test range for base station equipment in frequency bands below 6 GHz, and describes the methods for testing the indicators of that test system. It applies to the testing of compact range OTA test systems for base station equipment of types 1-O and 1-H operating below 6 GHz, in the context of 5G digital cellular mobile telecommunication networks.

It is used by laboratories and manufacturers that build, operate or verify compact range OTA test systems, by base station equipment makers who test their products with such systems, and by telecommunication operators that rely on the results. It is a voluntary standard issued by the Ministry of Industry and Information Technology on 15 April 2026 and effective from 1 August 2026. It is a new standard.
