System 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. Figure 1-1. MobileAccessGX - Radome Covered Pole Mounted GX Units MobileAccessGX Installation and Configuration Guide 1.1 Features and Capabilities • • • • • • • • Multi-Frequency/Multi-Service RF Transport Platform: Accommodates GSM, UMTS, HSPA, LTE, EDGE, EV-DO, and more.

Compliant to IP65/NEMA standard. Management and control – alarm forward to NOC or standard EMS via SNMP, software controlled output power and Optical link auto gain control MobileAccessGX Installation and Configuration Guide 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. MobileAccessGX Installation and Configuration Guide 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 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. Figure 1-5: Example of GX Configuration Tab MobileAccessGX Installation and Configuration Guide 1.4 GX Unit Interfaces All of the GX interfaces are located externally on the underside of the unit (facing down when unit is mounted).

LED Descriptions MobileAccessGX Installation and Configuration Guide 2 System Installation This chapter describes the installation procedure for the MobileAccessGX Remote Units. 2.1 Site Considerations • • • • • 2.1.1 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 2.5. 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. 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 that of temperature ranges from -40~55 C 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 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 • • • • • • • • • • 2.3 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 length 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. 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. MobileAccessGX Installation and Configuration Guide 2.4 Assembling Radome on GX – TBD Radome (optional) must be assembled before the unit is mounted. 2.5 Assembling External Filter (If Required) An external filter is required in installations where the GX remote unit is deployed with units supporting the 800MHz band. NOTE 1: The External Filter is not supplied with the GX unit and must be ordered separately. NOTE 2: If possible, it is recommended to perform this procedure before the GX unit is mounted.

MobileAccessGX Installation and Configuration Guide 33 4 Provisioning the MobileAccessGX Once the required physical connections have been completed, the GX unit is automatically detected (auto-discover) by the SC-450 and can be remotely monitored and managed. 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 Optical Control Hub (OCH) (that is connected to the controller). Thus, the controller monitors views and manages the GX via the OCH to which the GX is connected. Note: The provisioning procedure consists of two simple steps: assigning the unit name (Module Info tab) and clicking the Adjust button (Adjustment tab). Additional configuration options are available as well. Each GX unit can be managed via several dedicated panes that are accessed by clicking the relevant GX item in the SC-450 Topology Tree. 4.1 Accessing GX Management Options To access the MobileAccessGX management options In the Network Topology tree, expand the relevant Controller item, expand the relevant OCH (to which the GX is connected) and click on the GX. The GX alarms and management tabs appear. Controller Host OCH GX item Four management tabs GX Alarm status Figure 4-1: Example of GX Unit Module Info Tab MobileAccessGX Installation and Configuration Guide 34 The GX Alarms are continuously displayed (to the left of the tabs). The monitoring and configuration options are distributed over four tabs: • • • • 4.2 Module Info - device version and identification definitions RF Parameters – service control options. RF Adjustment – provides the adjustment options. Service Alarms – used for masking redundant alarms Basic Setup Procedure To perform basic setup 1. Verify that the alarms show green in the following tabs: • GX Cabinet Alarms – displays system level alarms Figure 4-2: Example of GX Alarms The following table provides a description of the device alarms shown above.

Mask irrelevant alarm conditions, in both tabs via the Modify button, to avoid having them reflected overall status of the GX unit (displayed in the GX Alarms area). For Example In the example below, the GX Alarms dialog shows the alarm response if the Service 2 DL Output Power Low alarm is NOT masked (enabled). In that case the Service 2 and Overall Status will be RED indicating a fault. RED - Unmasked alarm reflects on corresponding Service alarm and Overall Status Unmasked alarm If the Service 2 alarm is MASKED (Disabled), then the LED for the alarm will be RED; but, the corresponding Service alarm in GX Alarms area will be GREEN – showing NO Fault. Note: The Overall Status alarm will only show green if all of the generated alarms are masked (or if all alarms are green). GREEN - Masked DL Output Power Low alarm (for Service 2) alarm does not reflect on corresponding Service alarm in GX Alarms area. Masked alarm In the figure above the alarm condition for (Service 2) “DL Output Power Low” actually exists, while the masking prevents this condition from affecting the overall status of the service and therefore the Service 2 LED in GX Alarms area is green. MobileAccessGX Installation and Configuration Guide 37 3. Assign the unit a recognizable name (i.e. corresponding to its location): In the Module Info tab, click the Modify button, enter the required text and click OK. The assigned name will be displayed.

Installation Requirements The infrastructure preparation consists of two main phases: A. Floor Planning: Planning the distribution of the antennas on each floor to provide the required coverage. B. Telecom Closet Planning: Planning the layout of the devices and cables in the telecom closet or shaft. Coaxial Cable Connections 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 mechanical structures. • The cables should be supported only from the building structure. MobileAccessGX Installation and Configuration Guide 44 Appendix B: Ordering Information 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.

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. MobileAccessGX Installation and Configuration Guide 45 Appendix B: Ordering Information • • • • • 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 RU and RIU ports with a 50 ohm load Power Consumption, Connections and Power Supplies 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 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 • 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. Power Consumption of Units Table 4-2. MobileAccess Power Requirements Unit Type Voltage Input Power Consumption Maximum Current Consumption GX Remote Unit – Indoor Model Local: 90-264V AC or Remote: 36 to 75V DC 350W (max) GX Remote Unit – Outdoor Model Local: 90-264V AC or Remote: 36 to 75V DC 350W (max) Base Unit 20 to 48V DC 14W 0.7A SC-450 Controller 36 to 60 V DC 10W 0.2A MobileAccessGX Installation and Configuration Guide 46 Appendix B: Ordering Information Circuit Breakers Install fuse protections for the system according to the following criteria: • The following system elements require external fuse protection: RIUs, BUs, and SC450 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 future expansion, it is recommended to install additional optic fibers to be connected to additional RUs. Continued on the following page...

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 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 Remote Cabinet or MA2000-Lite system using coax cables.
