Introduction
As the requirement for mobile communication quality keeps enhancing, the
operators of wireless network need to pay more attention to improve the
network quality and expand the network coverage. Due to the change of
electromagnetic environment and increase of mobile subscribers, those existing
BTS may be unable to meet the specified performance requirements and the
following coverage problems will occur:
1. High call-drop rate 2. Low rate of successful handover 3. Low coverage
rate or bad coverage quality 4. Low connection rate 5. Bad conversation
quality To solve all these problems in an all-around way, only adjusting the
cell parameters of the BTS is not enough. The adoption of “BTS + Repeaters” is
a better solution that has been verified in many sites in village, highway and
tourism regions, especially at the edge of a BTS coverage region. And since
the repeater requires fewer accessories and no need special equipment-room,
operators can get more profit from lower construction and operation cost.
PROSE RADIANT is a multi-standards integration system, which has integrated
4G/5G and support for broadband access to this system. This system mainly
consists of four parts. Repeater is especial tailored to provide a
comprehensive and flexible coverage solution in complex coverage environments
like densely populated residential area, underground areas, tunnels, stations
and terminals, Hotels, Meeting rooms and shopping mall and so on. It widely
used on the mobile communication networks. The system receives filters,
amplifies, and transfers the uplink and downlink radio frequency (RF) signals
of the base transceiver station (BTS) to extend and accurately distribute the
coverage of the BTS.

2. System Introduction
Overview
PROSE’s solution of RADiAnt system supports multiple operators deploying
multiple mobile technologies. The RADiAnt system operates from 698-3980MHz and
extends 4G, 5G and broadband data coverage for indoor applications. It is
particularly suited for high-capacity application scenarios such as business
towers, shopping malls, offices, airports, stadiums, and other indoor
application scenarios. The RADiAnt is much more than just replacing RF coaxial
cables with optical fibers. The core of the system, consisting of the
intelligent Multisector Master Unit (IM2U) and the Network Extender Unit
(NEU), deals with the signal processing and the conversion of RF signals to
optical. The optical signals are transmitted over single mode fiber with low
loss and virtually no increased in noise floor. The NEU uses hybrid cable (an
integrated power and fiber cable) to connect to the integrated Remote Unit
(IRU-O), where each NEU can connect 16 units of IRU-O for SISO, and 16 units
of IRU-O for 2×2 MIMO, and 8 units of IRU-O for 4×4 MIMO applications. IRU-O
is designed to apply for indoor and outdoor environment. The IRU-O outdoor
type meets IP65. It had two types, one is combiner build in type, the other
one is

without combiner type. The different are the dimension, weight, and output
ports definition. If multiple operators accessing, the Power Balance Master
Unit (PBMU) is recommended for power level aligning.
The advantages of the RADiAnt system are: · Easy and quick to design and
deploy Fiber DAS, where RF radiated power is determined only by each IRU-O ·
Achieve uniformed coverage, each IRU-O provides constant output power for each
band · Precisely adjust the RF output power level in specific applications ·
Zero RF loss in signal transmission · No PIM and VSWR issues · One IM2U
connects a maximum of 16 NEUs, and one NEU connects up to 16 IRU-Os for 2×2
MIMO solution, supports 4X4 MIMO as well · Management via OMT or NMS software
Application

3.3.5.1 Ports introduction 3.3.5.1.1 CU PROSE developed two kinds of CU
(Combiner Unit). One is used with PBMU, the other is used with IM2U. Input
power range: 37 46 dBm. CU used with PBMU: 8 input (4.3-10 female) and 8
output (SMA female), support 698-3800 MHz. Each input and output are a group
of ports and ports are independent of each other.
Figure 3-55 Front panel of CU CU used with IM2U: 8 input (4.3-10 female) and 8
output (SMA female), support 698-3800 MHz. Input ports1~4 is a group, Input
ports5~8 is the other. One group of ports can only used for one band. For
example, input ports1~4 are all used for band 78 (3300-3800 MHz). The input
ports1~4 are combined to output ports1~4, ports5~8 are same.

3.3.5.1.2 PBMU The QMA ports on the front panel of PBMU are used to combine
the signal of the operators. Each set of the ports must be connected to same
band. For example, all the four ports of BTS_A can only combine band 78. The
eight groups of ports on the front panel correspond to the eight ports on the
back panel. Since each Channel port has a fixed band, which band the BTS ports
on the front panel connected to depends on which Channel ports the BTS port on
the back panel connected to. In 4T4R mode, one PBMU can support up to 8 NEUs.
There are 4 areas at the front panel of PBMU: A/B/C/D, each area has 8 optic
ports. The optic ports at the corresponding location of each area are
connected to the same NEU.
