1 Introduction
GX quad-band remote (“GX”) offers a cost-effective 40 W (46 dBm) high power remote outdoor coverage solution for MA2000
distributed antenna systems (DAS).
GX is a fiber-fed, multi-frequency, multi-operator remote designed to complement the MA2000 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-band remotes can distribute multiple BTS signal sources for
LTE700/CELL/ESMR/PCS1900/EAWS2100 to multiple remote locations from 2 to 15 km from the headend to remotes. GX
efficiently supports all operator modulations with linear multi-carrier power amplifier (MCPA) up to 40 W.
GX remotes share a common equipment head end and element management system (EMS) with other remotes on the
MA1K/MA2K platform.
GX offer high RF power coverage capabilities with compact design for added spaces savings and weather resistant
enclosures to fit various site needs.

1.1 System Architecture
GX 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. GX consists of a uniquely designed, non-obtrusive unit
that includes all of the required RF, fiber optic and power interfaces. All mobile services are distributed through service/band
dedicated RF connection ports over antennas installed at the remote locations.
IMPORTANT! GX quad-band models GX-E17E85P19L70-40-AC and GX-E17E85P19L70-40-DC do not support coexistence
with other GX models. These must be connected to a different RIU or different sector (for RIU-12) and to a different optical
module of the OCH. Connecting these GX models to the same RF paths as other GXs may result in a VSWR alarm.
1.1.1 SISO Scenario
Figure 1-2 illustrates a scenario including one GX quad-band remote and one GX tri-band remote. Note that all site elements
are managed and controlled via a single SC-450 controller (software version 5.4 and higher) that enables local and remote
management, and provides single-source, centralized common headend controls of all installed elements.
For the GX path, at the headend, the BTS or BDA signal is conditioned by the RIU, ensuring a constant RF level. The
conditioned RF electrical signal is then converted by the optical central hub (OCH) to an optical signal for transport to/from
multiple GX remotes, over low-loss fiber cabling.
*In installations including a GX supporting the CELL band and a GX supporting the Sprint800 band, the CELL and Sprint service
signals must be conditioned via two independent sectors in the RIU-12 (i.e., SectorA and SectorB in Figure 2) and routed through
dedicated optical modules in the OCH. Note the following:
Installations with RIU-4 units require a dedicated RIU-4 per GX model
Either an OCH-4 unit per GX or an OCH-8 (supporting two separate optical modules) is used
**External Combiner Insertion Loss of 1.0 dB
Figure 1-2. GX SISO Architecture
Corning Optical Communications User Manual I CMA-336-AEN I Page 11
1.1.2 MIMO Scenario
Figure 1-3 illustrates a MIMO scenario supported by two GX Quad-Band units. In MIMO installations each MIMO stream is
supported by a single GX unit. The MIMO1 and MIMO2 services are conditioned via two independent sectors in the RIU-12
(i.e., SectorA and SectorB) and routed through separate optical modules in the OCH. Note the following:
Installations with RIU-4 units require a dedicated RIU-4 per GX model
Either an OCH-8 (supporting two separate optical modules) or an OCH-4 unit per GX is used
*Eternal Combiner Insertion Loss of 1.0 dB
Figure 1-3. GX MIMO System Architecture
Corning Optical Communications User Manual I CMA-336-AEN I Page 12
1.1.3 Signal Path
In the downlink path, combined RF signals (from up to four supported services) from the radio interface unit (RIU) are
converted into optical signals by the 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.
In the uplink path, GX converts the RF signals transmitted from the service antennas into optical signals. The signals are
transmitted via optical fiber to the OCH 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 wavelength division technology (WDM).
Figure 1-4. GX Functional Block Diagram
Corning Optical Communications User Manual I CMA-336-AEN I Page 13
1.2 System Monitoring and Management
The GX-Quad Remote Unit is centrally managed via the MobileAccess SC-450 Controller.
Note: The GX Quad-band solution is supported by SC-450 v5.4 and higher.
The GX remote 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 via the OCH-GX, hosting the GX unit.
The following shows the Configuration tab of the selected GX unit. The system configuration and management is described in
the SC-450 user manual (v5.4 and higher).
Note: The EAWS band is supported from software version 7.4 and higher.

2 Installation Guidelines
This chapter provides the general guidelines for installing the GX Quad-band Remote Unit and includes information such as
site considerations and installation requirements.
2.1 Site Considerations
The distance between the GX service antenna and the coverage area should correspond to line of sight (LOS)
requirements for maximum coverage area.
The maximum fiber path loss is 6 dB.
The system delay of the optical system must be taken into consideration when there are neighboring BTS sites
overlapping in coverage.
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 maximum 95%.
2.1.3 Powering
The power supply unit 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 Quad-band unit, external combiner, antennas and all
cables connected to the system. Ensure lightning protection for the antennas is properly grounded.
2.1.5 Cable Routing
Ensure all cables, e.g. power cable, feeder cable, optic fiber, commissioning cable, connecting are properly routed (use driploops) 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.
