PrimAer 28GHz Operating Manual
System Specification
4.1 System Specification
The PrimAer 28 is a 2X2 MIMO equipment for US 5G NR service, and is designed to operate 850MHz
bandwidth in the mmWave 28GHz frequency band. This system satisfies the following functions and
performance characteristics, and if not specially mentioned satisfies 3GPP performance request.
- This system's DU transmit/receives RF signal wirelessly with the base station, and the SU is installed
in radio-shaded areas to eliminate radio-shade.
- The wireless quality of 5G NR service in this system satisfies at least 80% performance of the base
station wireless quality.
- This system supports continuous communication hand over on the UE when the UE is moving to
an adjacent base station.
