1.1 System Background
R8860E GU198 is the outdoor dual-mode RF remote unit in the ZTE ZXSDR series base
station products.
ZTE Corporation has launched a series of base station products to satisfy various
requirements of operators. One of the solutions is dividing the base station into two parts:
Base Band Unit (BBU) and Remote Radio Unit (RRU). R8860E GU198 is the outdoor
RRU, and it works with BBU to realize complete logical functions of a base station.
R8860E GU198 adopts the multi-carrier technology as its core technology. It supports two
radio systems: GSM and UMTS. R8860E GU198 can be used as an independent RRU
for GSM or an independent RRU for UMTS, and it works with BBU to form the dual-mode
base station.
1.2 System Positions
1.2.1 System Position in Network
The GSM/UMTS system consists of four parts:
Base station (BTS/Node B)
Radio network controller (BSC/RNC)
Core Network (CN) system
Mobile station (MS/UE)
Figure 1-1shows the position of R8860E GU198 in the GSM/UMTS network.

Figure 1-1 R8860E GU198 POSITION IN GSM/UMTS NETWORK
BTS/Node B, which provides the radio coverage of GSM/UMTS network, performs the
following functions:
l Realizes MS/UE access and radio link transmission through Um/Uu interface.
l Connects with BSC/RNC through Abis/Iub interface, reports BTS/Node B
measurement information, broadcasts system information provided by BSC/RNC,
executes commands issued by BSC/RNC (such as access control, mobility
management, and radio resource management), and performs FP processing and
transmission management.
The distributed BTS/Node B system consists of BBU and RRU. R8860E GU198 realizes
the function of RRU, and works with the dual-mode BBU to form the BTS/Node B base
station.
1.2.2 BBU and RRU
Functions

Chapter 1 System Overview
The base station is divided into BBU and RRU. One BBU provides the base band
resource for multiple RRUs
BBU performs digital base band signal processing and control management.
RRU performs conversion of the digital base band signal and the analog RF signal
between BBU and antenna.
BBU connects with RRU through the baseband-RF interface (optical interface), and
transmits I/Q digital base band signal and OAM signaling data.
BBU connects with BSC/Node B through Abis/Iub interface.
RRU realizes MS/UE access through Um/Uu interface.
Distributed Base Station Architecture
BBU and RRU constitute the distributed base station system. One central BBU manages
a group of RRUs, realizing rapid and flexible configuration and networking for the
base station system. The BBU+RRU solution is a more flexible mode for base station
establishment. It reduces requirements for the equipment room and the feeder cable loss.
BBU is arranged indoors and connected with RRU (usually arranged outdoors) through
optical fiber, as shown in Figure 1-3.

ZTE Proprietary and Confidential
Chapter 4 Installation
Warning!
It is not allowed to drill chassis holes without permission.
à
Unqualified drilling could damage wiring and cables inside the chassis.
Additionally, metal pieces inside the chassis created by the drilling could result
in a short circuit. Use insulation protection gloves and first move cables inside a
chassis away when drilling is necessary on a chassis.
à
Protect eyes during drilling as dust or flying debris may damage eyes.
à
Clean any debris in time after drilling.
Lightning
Danger!
Do not perform high-voltage, AC, iron tower or mast operations in a thunderstorm.
Thunderstorms would give rise to a strong electromagnetic field in the atmosphere.
Therefore, the equipment must be grounded and protected in time against lightning
strikes.
Antistatic Safety Instructions
Caution!
Static electricity produced by human body can damage static-sensitive components on
circuit board, such as large-scale integrated circuits.
Friction caused by human body activities is the root cause of electrostatic charge
accumulation. Static voltage carried by a human body in a dry environment can be
up to 30 kV, and can remain there for a long time. An operator with static electricity
may discharge electricity through a component when he/she touches the conductor
and causing damage.
Wear an antistatic wrist strap (the other end of wrist strap must be well grounded)
before touching the equipment or holding a plug-in board, circuit board, Integrated
Circuit (IC) chip or other devices, to prevent human static electricity from damaging
sensitive components.
The antistatic wrist strap used must be subject to regular check. Do not replace the
cable of an antistatic wrist strap with any other cables.
4-5
SJ-20101210110401-002|2011-05-31
ZTE Proprietary and Confidential
ZXSDR R8860E GU198 User Manual
Do not contact static-sensitive modules with any object that easily generates static
electricity. For example, friction of package bag, transfer box and transfer belt made
from insulation plastic may cause static electricity on components. Discharge of static
electricity may damage components when they contact a human body or the ground.
Modules should only contact materials such as an antistatic bag. Keep modules in
antistatic bags during storage and transportation.
Discharge static electricity of the test device before use, that is, ground the test device
first.
Do not place the module near a strong DC magnetic field, such as the cathode-ray
tube of a monitor. Keep the module at least 10 cm away.
Hoisting Heavy Objects
Warning!
When hoisting heavy objects, ensure that nobody is standing or walking under the hoisted
object.
Ensure the hoister can meet hoisting requirements when disassembling heavy
equipment, or moving and replacing equipment.
The installation personnel must be duly trained and qualified for hoisting operations.
Hoisting tools must be inspected and complete before service.
Make sure that hoisting tools are fixed firmly on a sufficiently secured object or wall
before the hoisting operation.
Give brief oral instructions during hoisting operations to prevent any mishap.
Unplugging/Plugging a Module
Never plug a module with excessive force, to ensure that the pins on the backplane
do not get deformed.
Plug the module right into the slot and make sure module circuit faces do not contact
each other lest any short circuit may occur.
Keep hands off the module circuit, components, connectors and cable trough when
holding a module.
Rack Mount Safety Instructions
Rack Mount Instructions - The following or similar rack-mount instructions are included
with the installation instructions:
Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the
operating ambient temperature of the rack environment may be greater than room
ambient. Therefore, consideration should be given to installing the equipment in an
environment compatible with the maximum ambient temperature (Tma) specified by
the manufacturer.
4-6
SJ-20101210110401-002|2011-05-31
ZTE Proprietary and Confidential
Chapter 4 Installation
Reduced Air Flow - Installation of the equipment in a rack should be such that the
amount of air flow required for safe operation of the equipment is not compromised.
Mechanical Loading - Mounting of the equipment in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
Circuit Overloading - Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of the circuits might
have on overcurrent protection and supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.
Reliable Earthing - Reliable earthing of rack-mounted equipment should be
maintained. Particular attention should be given to supply connections other than
direct connections to the branch circuit (e.g. use of power strips).
Other Safety Instructions
Note:
Do not perform maintenance or debugging independently, unless a qualified person is
present.
Perform an airtight test before RRU delivery, and prohibit disassembling the RRU on
site.
Replacing any parts or making any changes to the equipment might result in an
unexpected danger. Therefore, be sure not to replace any parts or perform any
changes to the equipment unless authorized otherwise.
Due to that RRU is in high temperature during running, the RRU should be installed
in some regions out of operators' reach or strictly restricted.
