MobileAccessGX offers a scalable, cost-effective 20/40W (43/46dBm) high power remote
outdoor coverage solution for Corning MobileAccess Distributed Antenna Systems (DAS). It is a
fiber-fed, compact, multi-service, multi-operator remote designed to complement the
MobileAccess1000 and MobileAccess2000 lower power, standard remotes or installable as a
dedicated deployment solution in a new site, providing complete RF coverage options for open
indoor, tunnel and adjacent outdoor spaces in larger venues such as stadiums, convention
centers, metro-rails and malls.

GX supports multiple wireless technologies and operator services over a single broadband
infrastructure. Using low loss fiber optic cabling, GX remote units can cover distances between 2­15km from the BTS signal sources at the head -end.

Front-end wireless RF services are routed over optic fibers to GX series remote units, which are
securely located at each remote location. These modular service aggregation platforms precisely
combine multiple wireless service signals for simultaneous distribution over a common
broadband infrastructure. GX supports all major modulations in mixed mode with high efficiency
and linear MCPA up to 40W.

The solution can be deployed in new sites or alongside existing MobileAccess1000 (MA1000)
and/or MobileAccess2000 (MA2000) remotes, sharing a common head-end and element
management system (EMS).

High, RF power coverage capabilities and compact, space saving, weather resistant design
ensures optimal coverage for various site needs .

MobileAccessGX Installation and Configuration Guide 2

1.2 System Architecture

MobileAccessGX provides a complete solution consisting of GX remote units at the remote
locations, and head-end elements, which are shared with any existing or new MA1000/MA2000
deployment.

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 FT-350 OCH (Optical Control
Hub) to an optical signal for transport over single-mode fiber 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, MA1000 and MA2000
elements from a single, centralized location.

The MobileAccessGX Remote Unit consists of a uniquely designed, non-obtrusive unit that
includes all of the required RF, F/O and power interfaces. The GX product supports four service
types: CELL/PCS/LTE 700/AWS – each unit supports up to 3 bands, whereas the supported
bands depend on model (see Appendix B: Ordering Information). All mobile services are
distributed through service/band dedicated RF connection ports over antennas installed at the
remote locations.

Figure 1-2. System Architecture

NOTE: When MobileAccess GX unit is deployed with units supporting the 800MHz band, an
external filter is needed to be installed on the GX to avoid the disturbance between the 800MHz
DL and the 850MHz UL frequencies.

1.2.1 Signal Path

1.2.1.1 SISO Signal Path

On the DL, combined signals up to tri-band from the OCH converted into optical signals. Then
the optical signals are transmitted to the RU via optical fiber. The Optical TX/RX Module of RU
converts the DL optical signals into RF signals. After filtering signal for each band and
amplification, the signals are transmitted at the output port (700MHz/CELL850/PCS/AWS) to the
service antenna.

On the UL, the signals transmitted by the mobile are converted into optical signals, and then via
the UL optical fiber. The signals are transmitted to 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 WDM technique.

Figure 1-3. GX Functional Block Diagram – SISO Configuration

1.2.1.2 MIMO Signal Path

In MIMO system, the principle is similar to the single system. In MIMO, Dual-DL and dual-UL are
required, e.g. 700LTE / AWS. So two GX remote units are connected to the OCH. A pair of
optical fiber in same length is needed for the remote units to ensure the same time delay to both
units.

Figure 1-4. GX Functional Block Diagram – MIMO Configuration

1.3 System Monitoring and Management

The MobileAccessGX Remote Unit is centrally managed via the MobileAccess SC-450 Controller.

Note that MobileAccessGX is not connected directly to the controller. It is connected to the FT-

MobileAccessGX Installation and Configuration Guide 4

350 OCH element (that is connected to the controller). Thus, the controller monitors views and
manages the GX via the OCH to which the GX is connected.

The following shows the Config(uration) tab of the selected GX unit. The system configuration
and management is described in Chapter 4.

This chapter describes the installation procedure for the MobileAccessGX Remote Units.

2.1 Site Considerations

 The distance between the GX 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 remote unit is deployed with units supporting the 800MHz band, an external

filter is needed to be installed on the GX to avoid the disturbance between the 800MHz DL
and the 850MHz UL frequencies. See section Error! Reference source not found..

 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 equipme nt.

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 v entilated. The equipment has been
designed to operate at the temperature range and humidity level as stated in the product

specifications that of temperature ranges from -40~55oC and the relative humidity is at most
85%.

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 antennas and all cables
connected to the system. Ensure lightning protection for the antennas is properly grounded.

MobileAccessGX Installation and Configuration Guide 8

2.1.5 Cable Routing

Ensure all cables, e.g. power cable, feeder cable, optic fiber, commissioning cable, connecting
are properly routed 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 leng th 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.
 Ensure same length for a pair of optic length for units in MIMO scenario.

2.3 Fiber Optic Rules

Attention!

Please 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 SC/APC connectors (green color) 8 deg only.
 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.
 Pay special attention while connecting the SC/APC connectors - you must hear the “click”

when the connection is made.

General Cable Installation Procedures

Observe the general cable installation procedures that meet with the building codes in your area.
The building code requires that all cabling be installed above ceiling level (where applicable).
The length of cable from the risers to each antenna must be concealed above the ceiling.

The cable must be properly supported and maintained straight using tie -wraps, cable trays and
clamps or hangers every 10 feet (where practical above ceiling level). Where this is not practical,
the following should be observed:

 The minimum bending radius of the supplied ½” coax cable should be 7”.
 Cable that is kinked or has a bending radius smaller than 7” must be replaced.
 Cable runs that span less than two floors should be secured to suitably located

 The cables should be supported only from the building structure.

Fiber Optic Rules

 Either single mode or multimode fiber can be used with MobileAccess2000M products,

while MobileAccess2000 products can only be used with single mode fiber.

 Only Multimode fiber, 50/125 or 62.5/125um complying with ANSI/TIA/EIA -568-B series,

EN50173-1 or ISO/IEC 11801 can be used. The fiber length can be up to 300 meters
assuming the following qualifications:

 All fiber in a given length of fiber must be of the same core diameter.
 All Bulkhead adapters must be Single mode SC/APC (Green) adapters.
 All terminations cross connections or patches must be direct fusion splice or

Appendix B: Ordering Information

MobileAccess specified patch cords listed below.

 Use only 8-degree SC/APC connectors (green color).
 Use only fusion splice for connecting two fibers.
 Use minimum splicing/connectors to achieve minimum losses on the fibers (<0.5dB).
 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.

 Verify the Fiber Optic connections. You may use the Optical Test Procedure described at

the end of this manual.

 Pay special attention while connecting the SC/APC connectors - you must hear the “click”

when the connection is made.

RF Rules

 Use coax RG223, 50ohm, male-to-male N-type for RF connections from the BUs to the

BTS/RBS and to the RIU.

 When using the MobileAccess system in an environment in which other indoor coverage

systems are installed, it is recommended (where possible) that the antennas are pl aced
at least two meters apart

 When bending coax cables, verify that the bending radius does not exceed the coax

specifications.

 Use wideband antennas supporting a range of 800Mhz to 2500Mhz
 Use a VSWR meter (i.e. Site Master or equivalent) for checking coax cables, including

the antennas. (<2). The VSWR must be measured prior to terminating the RUs in the
remote communication rooms

 Terminate all unused RU and RIU ports with a 50 ohm load

Power Safety Instructions

SAFETY WARNINGS

 When installing or selecting the power supplies:
 Be sure to disconnect all power sources before servicing.
 SC-450 Controller lithium type battery should only be replaced by MobileAccess service

personnel. Risk of exploding if battery is replaced by an incorrect type. Dispose
of used batteries according to the instructions.

 Calculate the required power according to the requirements of the specific installation

and then determine the configuration of the power suppli es. The required DC cables will
then be determined by the selected PS configuration.

 Use only UL approved power supplies
 AC and DC power supply cables – only use the power cords supplied with the units
 Battery replacement in units - only the SC-450 controller has batteries. These should

be replaced (when necessary) only by MA Service Personnel.

 Install external over-current protective devices for the system according to the

requirements.

Circuit Breakers

Install fuse protections for the system according to the following criteria:

 The following system elements require external fuse protection: RIUs, BUs, and SC-

450 Controllers.

 Referring to Table 4-2, calculate the required fuse protection.
 Example: a set of three elements consisting of a BU, RIU and SC-450 controller

requires a 2A circuit breaker.

Types of Power Supplies

MobileAccess supplies various power supplies that can be installed in a rack or mounted on a
wall, depending on your configuration.

Installation Conventions

Some of the basic installation conventions are listed below for the MA 2000 system:
 Base Units – are usually concentrated in the same location, most often in the main

communication room.

 Remote Cabinet/Lite – usually placed in the communication shaft or closet of a

corresponding floor so they can be easily located. Each cabinet (or MA2000-Lite) can
typically cover a floor of up to 30,000 sq ft.

 Fiber optic cable - bundled fibers are terminated into the Base Units in the main

communication room. The fibers are then routed to each coverage locations where
individual fibers terminate into splice boxes. The splice box couples the installed fiber
into the remote units. Enough spare fibers should be installed to take into account
future expansion of the system.

For example, for three remote units, six fibers are required. However, to allow for futur e
expansion, it is recommended to install additional optic fibers to be connected to additional
RUs.

MobileAccessGX Installation and Configuration Guide 46

Appendix B: Ordering Information

The following figure illustrates fiber optic routing to Remote Cabinets.

Figure 4-7. Illustration of Fiber Optic Routing

 For remote power supply configuration - cable bundles are routed from the main

communication room and individual wire pairs are terminated into the power feed of
individual units.

By providing power from a single distribution point, maintenance can be reduced and UPS
backup can be easily provided. The maximum distance from the source to the termination
spot is 1000 feet using 18 gauge wires.

In many locations local codes do not require power to be r un through conduit if 100 watts or
less is used. Please consult the regulations in your local jurisdiction prior to deploying
remote power. When power cables require distances greater than 1000 feet 14 or 16 gauge
wire may be used.

 On each floor - the antennas are connected to the Remote Cabinet or MA2000-Lite system

using coax cables.
