Introduction I P/N: 709C0011101I Page 1 1 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). 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. 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. MobileAccessQX Figure 1-1 1.1 Key Features and Capabilities The following benefits are achieved with the QX platform: • 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 a common DAS antenna infrastructure. • Optic Fiber savings - All services routed to a QX unit are routed over a single optic fiber • Modular Design - Seamless service upgrades – simply add a card in the QX (and the parallel service conditioning module at the head end) • 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
System Architecture I P/N 709C011101 I Page 2 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 3 • 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.

Installation Guidelines I P/N: 709C0011101I Page 8 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.
Coaxial Cable Connections I P/N 709C011101 I Page 9 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. Coax Length coax Loss (900Mhz) connector loss Total Loss 30 0.7 1.5 2.2 40 0.9 1.5 2.4 50 1.1 1.5 2.6 60 1.3 1.5 2.8 70 1.5 1.5 3 80 1.7 1.5 3.2 90 1.9 1.5 3.4 100 2.1 1.5 3.6 110 2.3 1.5 3.8 120 2.5 1.5 4 130 2.7 1.5 4.2 140 2.9 1.5 4.4 150 3.1 1.5 4.6 160 3.3 1.5 4.8 170 3.5 1.5 5 180 3.7 1.5 5.2 190 3.9 1.5 5.4 200 4.1 1.5 5.6
Fiber Optic Rules I P/N 709C011101 I Page 10 2.4 Fiber Optic Rules • Either single mode or multimode fiber can be used with QX products. • 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 MobileAccess specified patch cords listed below. 900 microns pathcord for splicing, 2 Meters, 2xSC/APC Diamond p/n ENC/1045341 Beige boots, 62.5/125/900 MA# 500001057 Diamond p/n ENC/1045340 Black boots, 50/125/900 MA# 500001058 Zipcord patchcord, 4xSC/APC, 50/125/900/2000/4500 micron Diamond p/n ENC/1045342 Black/Brown boots, 1 Meter MA# 50000105 Diamond p/n ENC/1045343 Black/Brown boots, 3 Meter MA# 500001060 Zipcord patchcord, 4xSC/APC, 62.5/125/900/2000/4500 micron Diamond p/n ENC/1045344 Beige/Brown boots, 1 Meter MA# 500001061 Diamond p/n ENC/1045345 Beige/Brown boots, 3 Meter MA# 500001062 • 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. • Pay special attention while connecting the SC APC connectors - you must hear the “click” when the connection is made.
Power Consumption, Connections and Power Supplies I P/N 709C011101 I Page 11 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. • 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.
