1 Introduction
MobileAccessGX-Quad offers a cost-effective 40 W (46 dBm) high power remote outdoor
coverage solution for Corning MobileAccess Distributed Antenna Systems (DAS).
MobileAccessGX-Quad is a fiber-fed, multi-frequency, multi-operator remote designed to
complement the MobileAccess1000 and MobileAccess2000 lower power, standard remotes. GX
can also be installed as a dedicated solution for new sites, providing complete RF coverage
options for open indoor, tunnel and adjacent outdoor spaces.
Using low loss fiber optic cabling, GX-Quad remote units can distribute multiple BTS signal
sources for CELL/PCS/700LTE or AWS to multiple remote locations between 2 to 15 km from
the head end to remotes. GX efficiently supports all operator modulations with linear MCPA
(multi-carrier power amplifier) up to 40 W.
MobileAccessGX-Quad remotes share a common equipment head end and Element Management
System (EMS) with other remotes on the MobileAccess1000/2000 platform.
GX-Quad remotes offer high RF power coverage capabilities with compact design for added
spaces savings and weather resistant enclosures to fit various site needs.

1.2 System Architecture
MobileAccessGX-Quad provides a complete solution consisting of GX-Quad remote units at the
remote locations, and head end elements, which are shared with any existing or new
MA1000/MA2000 deployment.
MobileAccessGX-Quad Remote Unit consists of a uniquely designed, non-obtrusive unit that
includes all of the required RF, F/O and power interfaces. All mobile services are distributed
through service/band dedicated RF connection ports over antennas installed at the remote
locations.
The following figure illustrates a scenario in which MobileAccessGX-Quad is installed alongside
MobileAccess2000 remotes and MobileAccessHX remotes. Note that all site elements are
managed and controlled via a single SC-450 Controller. All site elements (in this scenario
example), are controlled and managed by the SC-450 Controller that enables local and remote
management, and provides single-source, centralized „common head end‟ controls of MA1000,
MA2000, HX and GX-Quad elements.
In the downlink, at the head end, the BTS or BDA signal is conditioned by the RIU, ensuring a
constant RF level. The conditioned signal is then converted by the OCH-GX (GX Optical Central
Hub) to an optical signal for transport over single mode to the GX remote units, which are
located at the remote locations. In the uplink, the process is reversed. The SC-450 Controller
enables local and remote management, as well as controls all GX-Quad, MA1000 and MA2000
elements from a single, centralized location.

GX Architecture Diagram
Figure 1-2
NOTE: When MobileAccessGX-Quad unit is deployed with units supporting the 800MHz band, an
external filter is needed to be installed on the GX-Quad to avoid the disturbance between the
800MHz DL and the 850MHz UL frequencies.
Introduction
P/N 709C010701
Page 15
1.2.1 Signal Path
On the DL, combined RF signals (from up to four supported services) from the Radio Interface
Unit (RIU) are converted into optical signals by the Optical Control Hub (OCH). The optical
signals are then transmitted to the GX at the remote site via optical fiber. The signals are
filtered and amplified at the GX and transmitted through the service specific output ports to the
broadband antennas.
On the UL, GX converts the RF signals transmitted from the service antennas into optical
signals. The signals are transmitted via optical fiber to the OCH-GX which then converts the
optical signals back to RF signals.
The optical DL and UL signal are transmitted in a single optical fiber based on the WDM
technology.
GX Functional Block Diagram
Figure 1-3
1.3 System Monitoring and Management
The MobileAccessGX-Quad Remote Unit is centrally managed via the MobileAccess SC-450
Controller.
NOTE: The GX-Quad solution is supported by SC-450 v5.4 and higher.
MobileAccessGX-Quad is not connected directly to the controller; it is connected to the OCH-GX
element (that is connected to the controller). Thus, the controller monitors views and manages
the GX-Quad via the OCH-GX, hosting the GX unit.
The following shows the Config(uration) tab of the selected GX unit. The system configuration
and management is described in the SC-450 UM (v5.4 and
higher).

2 Installation Guidelines
This chapter provides the general guidelines for installing the MobileAccessGX-Quad Remote
Unit and includes information such as site considerations and installation requirements.
2.1 Site Considerations
The distance between the GX-Quad service antenna and the coverage area should
correspond to LOS (Line of Sight) requirements for maximum coverage area.
The maximum fiber path loss is 6dB.
The system delay of the optical system must be taken into consideration when there are
neighboring BTS sites overlapping in coverage.
When the GX-Quad remote unit is deployed with units supporting the 800MHz band, an
external filter is needed to be installed on the GX-Quad to avoid the disturbance between
the 800MHz DL and the 850MHz UL frequencies. See section 3.1.
In the MIMO scenario, two remote units shall use a pair of optic fiber for each one. This
ensures to avoid the system delay difference between two units.
2.1.1 Installation Location
Mounting surface shall be capable of supporting the weight of the equipment.
In order to avoid electromagnetic interference, a proper mounting location must be selected to
minimize interference from electromagnetic sources such as large electrical equipment.
2.1.2 Environmental
Humidity has an adverse effect on the reliability of the equipment. It is recommended to install
the equipment in locations having stable temperature and unrestricted air-flow.
The installation location for the system should be well ventilated. The equipment has been
designed to operate at the temperature range and humidity level as stated in the product
specifications at temperatures ranging from -40~70oC and a relative humidity of max. 95%.
2.1.3 Powering
The power supply unit (PSU) provides power to all modules within the equipment. Depending
on the product variant, it is recommended that the PSU operates on a dedicated AC circuit
breaker or fused circuit.
2.1.4 Grounding Requirement
Verify that the equipment has been well grounded. This includes GX unit, external combiner,
antennas and all cables connected to the system. Ensure lightning protection for the antennas
is properly grounded.
Installation Guidelines
P/N 709C010701
Page 20
2.1.5 Cable Routing
Ensure all cables, e.g. power cable, feeder cable, optic fiber, commissioning cable, connecting
are properly routed (use drip-loops) and secured so that they are not damaged.
2.1.6 Manual Handling
During transportation and installation, take necessary handling precautions to avoid potential
physical injury to the installation personnel and the equipment.
2.2 Installation Requirements
Working space available for installation and maintenance for each mounting arrangement.
Ensure unrestricted airflow.
Ensure grounding connector is within reach of the ground wire.
Ensure a power source is within reach of the power cord and the power source has
sufficient capacity.
Where appropriate, ensure unused RF connectors are terminated.
Do not locate the equipment near large transformers or motors that may cause
electromagnetic interference.
Reduce signal loss in feeder cable by minimizing the length and number of RF connections.
Ensure the equipment will be operated within the stated environment (refer to datasheet).
Where appropriate, confirm available of suitably terminated grade of RF and optical fiber.
Observe handling of all cables to prevent damage.
Installation Guidelines
P/N 709C010701
Page 21
2.3 Fiber Optic Rules
ATTENTION!
Please also refer to the Laser Safety section in the document Preface.
Fiber optic cables require proper handling. Do not stretch, puncture, or crush the fiber
cable(s) with staples, heavy equipment, doors, etc.
Always maintain the minimum bending radius specified by the cable manufacturer. The
minimum bend radius is usually 10 times the cable's outer diameter. In the case of single
optical fiber that is not in a cable, the minimum bending radius to be observed is 30mm.
WDM, Wave Division Multiplexing, units require SMF
Use minimum splicing/connectors to achieve minimum losses on the fibers.
Use precaution while installing, bending, or connecting fiber optic cables.
Use an optical power meter and OTDR for checking the fiber optic cables.
Make sure the environment is clean while connecting/splicing fiber optic cables.
All fiber optic connections should be cleaned prior to attaching to termination points using a
dry cleaning device (i.e. Cletop or equivalent).
Fiber connector protective caps should be installed on all non-terminated fibers and
removed just before they are terminated.
Check the Fiber Optic connections.
System Installation
P/N 709C010701
