Introduction
MobileAccess2000 QX (QX) is a member of
the MobileAccess2000 family. It is a compact,
modular, cellular indoor coverage remote unit
supporting up to four services (currently,
CELL/PCS, LTE and AWS).
1.1 Key Features and
Capabilities
All services are received from the head-end,
over a single optic fiber and reconverted to
RF for convergence and distribution over a
common DAS antenna infrastructure.
•
Multi-Service Platform - Supports up to
four services.
Currently supported:
CELL, PCS, AWS, 700 MHz LTE
•
Multi-Operator Optimized Platform Services from a number of operators
can be supported by the same chassis
or by different units and distributed
over
common
DAS
antenna
infrastructure.
•
Optic Fiber savings - All services routed
to a QX unit are routed over a single
optic fiber
•
Modular Design upgrades – simply
QX
(and
the
conditioning module
•
Scalable MIMO Upgrades - Upgrade any
or all services from SISO to MIMO by
cascading another QX unit
•
Small Footprint - 3 U height rack
•
Simple maintenance - All connections
and monitoring LEDs located on front
panel,
Modular,
hot-swap,
field
replaceable service modules, including
fan modules
•
Web Management - Web management
via the SC-450 controller
Service support can be quickly added as
needed by inserting card like modules into
the chassis without any downtime or
additional cabling. In addition, two QX units
can be cascaded to provide various
combinations of SISO and MIMO services
distributed
over
the
same
antenna
infrastructure.
MA2000 QX is managed by opening a Web
session to the SC-450 Controller.
MA2000 QX operates along with an SCU-F
unit, which converges the services from one
or more MA2000 QX units and provides the
interface to the DAS infrastructure. Both QX
and SCU-F are described in this manual.

1.2 System Architecture
The QX and SCU-F are located at the floor level remote end. QX receives RF over optic service
signals from the head end, reconverts the signals to RF over copper, adjusts them to the
required level and outputs each service to dedicated interfaces. The signals are combined by
the SCU-F (along with services from other QX units) and distributed over a common DAS
(Distributed Antenna System) infrastructure.
In the uplink, cellular service signals received at the DAS are separated by the SCU-F and
routed to their dedicated QX ports. The signals are then converted to optic and forwarded to
the head-end for reconversion to RF and distribution to the relevant BTS or BDA systems.
Note: 3rd party equipment is sold separately (i.e. cabling, antennas).
QX Architecture Diagram
Figure 1-2
Headend:
At the headend CMA elements provide interface to the wireless service provider’s network,
condition the signals and convert them to optical signals for transportation over fiber optics
towards the remote ends.
•
Radio Interface Unit (RIU) - the RIU conditions and custom tunes the RF Downlink (DL)
signals from an operator’s signal source (BTS or BDA) to ensure a constant RF level. In the
Uplink (UL), the signal (at the required level) is routed back to the operator’s signal source.
System Architecture I P/N 709C011101 I Page 2
•
RF to Optic converter unit – this can either be a Base Unit (BU) or an Optical Control
Head End Unit (OCH), where the OCH is QX model specific. These are wideband units that
convert the RF Downlink (DL) signals from the RIU into optical signals for routing over
single or multi-mode fiber optic cabling (SMF/MMF) to/from the QX units located at the
remote locations up to 2Km away.
•
System Controller (SC-450) - the system controller enables centralized remote
management and control of MobileAccess elements. This unit connects directly to the RIU
and BU and/or OCH and allows management of these as well as their hosted elements (e.g.
QX) via a controller Web session.
Remote End:
At the remote end, the optical signal is reconverted to RF, filtered, amplified to the appropriate
level, combined with other signals and distributed over the broadband antenna infrastructure.
The QX unit is installed, along with the Four Port Service Combiner Unit (SCU-F). The QX
system remote end consists of the following elements:
•
QX - each QX unit provides coverage for four RF services (e.g. CELL, PCS, 700LTE and
AWS) via two types of service dedicated internal modules (RHU and AO). Each of these
modules is monitored via the Controller as an independent unit.
•
Service Combiner Unit (SCU-F): a passive module that combines and distributes the UL
and DL signals from one or more QX units to (up to) four broadband antennas.

1.3.2 QX Main Internal Modules
The QX main components consist of the following internal modules:
•
Remote Hub Unit (RHU) – service specific unit, supports two voice services, converts the
optical signals received from the BU/OCH to RF signals (and vice versa) and routes them to
the coax antenna infrastructure (via the Four Port Service Combiner Unit – SCU-F).
•
Add-On (AO) – adds an additional voice service to the host RHU (QX includes two AO
modules hosted by the RHU)
Note: The voice services are combined by the connected Service Combiner Unit (SCU).
•
Antenna Monitoring Unit (AMU) – digital unit that enables antenna monitoring and relay
messaging of the following information:
• Antenna status
• Fans status
• Fans control
• AMU/QX alarms.
The AMU is connected to the SCU. The AMU modules of a number of QX units can be daisy
chained to a single SCU-F (see section 3.5.2.1).
•
Fan Module – two extractable fans, simple to maintain and replace (see section 4.2).

Installation Guidelines
2.1 Infrastructure Preparation
This following installation rules are based on the assumption that site survey and installation
planning (including power requirements) have been completed.
2.2 Installation Requirements
The infrastructure preparation consists of two main phases:
Floor Planning: Planning the distribution of the antennas on each floor to provide the required
coverage.
Telecom Closet Planning: Planning the layout of the devices and cables in the telecom closet
or shaft.
2.3 Coaxial Cable Connections
2.3.1 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 7” is required for the supplied ½” coax cable.
•
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 mechanical
structures.
•
The cables should be supported only from the building structure.
Installation Guidelines I P/N: 709C0011101I Page 8
x
2.3.2 RF Rules
•
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 placed 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 SCU ports with a 50 ohm load
2.3.3 Coax Cable Lengths and Losses
Use coax ½”, 50ohm, male-to-male QMA type, for connecting to SCU broadband antenna ports.
NOTE: The required distance between the antennas (installed in the ceiling) depends on the infrastructure
and calculated path-loss. For example, if there is free space-loss between the antennas, a minimum distance
of 100 ft is required; if there are partitions (loss) between the antennas, a distance of less than 100 ft
between them is allowed.

It is required to install a circuit breaker of 7.5A for the DC supply circuit.
•
Be sure to disconnect all power sources before servicing.
•
Calculate the required power according to the requirements of the specific installation and
then determine the configuration of the power supplies. 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
2.5.2 Types of Power Supplies
CMA supplies various power supplies that can be installed in a rack or mounted on a wall,
depending on your configuration.
2.6 Installation Conventions
Some of the basic installation conventions are listed below for the QX system:
•
QX - usually placed in the communication shaft or closet of a corresponding floor so they
can be easily located. Each QX unit can typically cover a floor of up to 30,000 sq ft.
•
Fiber optic cable - bundled fibers are terminated into the Base Units/Optical Control Hubs
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 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 run 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 Service Combiner Unit (SCU) using
coax cables.
