Introduction I P/N: 709C0011101I Page 1
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 rem ote ends.
• Radio Interfac e Unit (RIU) - the RIU conditions and custom tunes the RF Downlink (DL)
signals from an ope rator’s si gnal source (BTS o r BDA) to ensu re a con stant 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 eit her be a Base Un it (BU) or an Optic al Contro l
Head End Unit (OCH), where th e OCH is QX model speci fic. 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 OC H an d all ow s man agem en t o f t hese as wel l as th ei r host ed el e ments (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 b roadband 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.

2 Installation Guidelines
2.1 Infrastructure Prepar ati on
This following installation rules are based on the assumption that site survey and installation
planning (including power requirements) have been completed.
2.2 Installation Requ irements
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 : Planni ng the l ayout of th e devices an d cabl es in the tel ecom clos et
or shaft.
2.3 Coaxial Cable Connections
2.3.1 General Cable Installat ion 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 f rom the risers t o each antenna mu st be conceal ed 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 tha n 7” must be replaced.
• Cable runs that span less than two floors should be s ecured to suit ably located mechan ical
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 i nstalled, it i s recommended (w here 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 2 50 0 Mhz
• Use a VSWR met er (i.e. Site Master or equivalent) for checking coax cables, including the
antennas. (< 2). The VSWR must be measu red prior to termin ating 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 t he antennas (installe d in the ceiling) de pends on the infrastr ucture
and calculated path-loss. For example, if there is free space-loss between the a ntennas , a minim um dista nce
of 100 ft is required; if there are partitions (loss) between the antennas, a distance of less than 100 ft
between them is allowed.

• 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 envir onment 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.
• Pay special attention while connecting the SC APC connecto rs - you must hear the “click”

2.5 Power Consumption, Connections and Power
Supplies
2.5.1 Power Safety Instructions
SAFETY WARNINGS
When installing or selecting the power supplies :
• 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.
• Calculat e the required power acc ording to the requi rements of the speci fic installation and
then determi n e th e con fi g urati on of the p ow er s uppl i es. Th e req ui red D C ca bl es wi ll th en 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 cov erage locations
where individual fibers terminate i n t o sp lice boxes. The splice box couples th e 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.
