GB/T 21195-2026Technical requirement and test method for mobile communication indoor signal distributing system antenna (English PDF)

GB/T 21195-2026 is the English-translated version of 移动通信室内信号分布系统天线技术要求和测试方法.

Antennas used in indoor signal distribution for mobile networks are the subject of this standard, which covers both technical requirements and test methods. Indoor distribution systems bring cellular coverage into buildings such as offices, malls, stations, and hospitals, and the antenna is a basic component of those systems.

The standard is relevant to antenna manufacturers, network equipment vendors, mobile operators, system integrators, and test laboratories that verify product performance. It is a recommended national standard (GB/T) and so is voluntary unless made binding by a purchase specification. This 2026 edition replaces GB/T 21195-2007, which means the earlier version should no longer be treated as the current reference once the new one applies. It was issued on 28 September 2026 and takes effect on 1 April 2027. Suppliers exporting such antennas to Chinese operators, and buyers specifying them, will want to work from the current edition.
