PrimAer 28GHz Operating Manual
2.2 System Network Configuration
PrimAer 28GHz network configuration shown below.
Figure 1. Network Configuration.
PrimAer receives a 28GHz wireless signal from a 5G base station to the DU, down converts to IF over
fiber, amplifies the signal then the SU up converts IF to 5G mmWave service.
PrimAer is configured with 3 units, the DU, SU, and Rectifier. The Rectifier supplies DC power to the
DU and SU, and is connected to the DU and SU with a power cable. Also, the DU and SU is connected
with a single fiber-optic cable, and multiple SU’s can also be connected in series through a single fiber-
optic cable.
The DU can support antenna beam forming to ±50˚ (Up/down/left/right) through GUI.
The DU and SU can support antenna beam steering to ±50˚ (Up/down/left/right) through GUI.
The DU and SU have Beamwidth ±30˚ in H-Plane/±15˚ in V-Plane
The DU and SU have internal Dual Polarized Antennas that support MIMO.
