System Overview
2.1 System Overview
2.1.1 Overview
PrimAer 39 is a 5G repeater system that can provide and/or enhance high quality telecommunications
service both in-building & outdoors. PrimAer 39 System can provide mmWave 39GHz frequency band
coverage to all venues.
PrimAer 39 system provides coverage for in-building and outdoor environments. A “proper RF design”
will provide a more accurate representation of the expected coverage.
This system can service mmWave 39GHz frequency band service and can be used for public and
private facilities.
39GHz Wireless Optic DAS system installation location:
-Shopping mall
-Hotel
-Campus
-Airport
-Subway
-Stadium and convention center
System frequency band :
- mmWave 39GHz SISO/MIMO (37.6GHz ~ 40.0GHz)
PrimAer 39 system is configured with a Donor Unit (DU), a Service Unit (SU_C: Cascading unit or SU_E:
End unit), and a Rectifier. 1 DU can operate up to 4 Service Units connected in a cascade configuration.

PrimAer DU receives the 39GHz 5G signal from the gNB over the air. The DU then amplifies the signal and
provides 5G service to the SU. The SU then extracts the TDD sync signal received from the gNB and
sends to each unit.
For outdoor usage, the DU, SU, and Rectifier are designed within IP66 specification so that dust,
pollutants, and insects cannot penetrate.

PrimAer 39GHz Operating Manual
Figure 1. Network Configuration
PrimAer 39 receives a 39GHz mmWave signal over the air from a 5G gNB to the DU. The DU then
converts the mmWave signal to IF over fiber and amplifies the signal. The SU then converts the IF to 5G
mmWave signal for service.
PrimAer 39 is comprised of 3 units, the DU, SU, and Rectifier. The Rectifier supplies DC power to the
DU and SU through a power cable. Also, the DU and SU's are connected with a single fiber-optic cable,
and multiple SU’s can also be connected in series with a single fiber-optic cable.
The DU can support antenna beam steering ±50˚ (Up/down/left/right) through the GUI.
The DU and SU have internal Cross Polarized Antennas that support MIMO.

3.1 DU Function and Configuration
The DU is in a single enclosure with a mounting bracket on the back enabling wall or pole attachment.
The DU receives a MIMO 5G gNB signal over the air, converts it to an optical signal, and sends it to the
SU via Fiber-Optic cable. (Downlink). It also converts the optical signal received from the SU via fiber-
optic cable and converts this back to 39GHz 5G RF which is sent to the gNB through the internal antenna.
(Uplink).
The DU is comprised of an antenna, DIFM, DAOM, and EMS board. The rectifier powers the DU
through the power port with -53.3V DC p o w e r.

PrimAer 39GHz Operating Manual
3.2 SU Function and Configuration
The SU is in a single enclosure with a mounting bracket on the back enabling wall or pole attachment.
The SU receives an optical signal from the DU via Fiber-Optic cable, converts it to a 39GHz RF signal, and
sends the 5G signal through the antenna. (Downlink). It also converts the 39GHz RF signal received from
the UE into an optical signal and sends it to the DU through Fiber-Optic cable. (Uplink)
When cascading there is the SU_C that connects between the DU and SU_E, the figure and
configuration is the same. Cascade can be up to 4 SUs, but the SU_E can only be at the end of the chain.
The SU is comprised of an antenna, SIFM, and SAOM module. The rectifier powers the SU through the
power port with -53.3V DC power
