MobileAccess™ 2000 converged wireless networks solution provides scalable in-building coverage for multiple wireless data and voice services through a single coax and broadband antenna infrastructure. The solution is based on combining a number of services, both voice and data, at each covered location. The services, supported by remote units are combined and interfaced to a common antenna infrastructure. Figure 1-1. MA 2000 System Overview Voice services are transmitted between the BTS side and the locations via optic fiber after the appropriate conversion from RF to optic, and reconverted to RF at each end. The MA 2000 scalable solution is available in various configurations designed to meet the needs of sites of various sizes: • Remote Cabinets – The remote cabinet is designed for larger sites requiring future safe support for several operators. The remote units supporting the services are compactly housed inside a cabinet that provides the required interfaces, filtering and combining functionalities. • 2000 Lite – The 2000 Lite is designed to provide coverage for smaller sites with fewer services, or as an entry-level solution for larger sites. This solution provides support for a few services implemented by one or two remote units. The remote units in this configuration are installed externally to the enclosure. Wireless 802.11/a/b/g coverage may be integrated into the MA 2000 system (either configuration) using the MA 850 remote module (that supports wireless LAN service distribution). Installation and Configuration Guide Introduction To optimize system coverage under changing environmental conditions or load, as well as to enable remote monitoring of all system elements from a central location, MobileAccess provides the following MA 2000 system enhancement solutions: 1.1.1 1.2 • Manageable BTS interface devices that control the level of the BTS signal fed into the system (Radio Interface Unit) • Network Management System (NMS) consisting of controllers, adjustment and management software Features • All services are distributed through a single coax and antenna infrastructure • Each Remote Cabinet can house up to five remote units supporting up to 20 services including 3G and 802.11a/b/g • Each 2000 Lite supports up to two remote units to which MA 1200 add-on modules may be connected, providing support for up to 8 services • Support for all current and future technologies such as TDMA, CDMA, WCDMA and GSM, and services such as PCS/CELLULAR, Paging, iDEN and 802.11 (a/b/g) Wireless LAN • Scalable and future-safe – additional remote units can easily be installed • Support for remote monitoring through MA 410/430 controllers • All active components are located in the communication closet/room System Architecture The MA 2000 solution is based on the following main elements: • MA Base Units (BUs) – The BUs perform RF to optic conversion on the BTS side. • MA Remote Units (RUs) 2000 – The MA 2000 performs the RF to optic signal conversion at the antenna side for up to two services corresponding to the RU model. A third service can be added by connecting an add-on remote hub unit (MA 1200) to the RU 2000. The RUs are housed in the 2000 Remote Cabinet. • MA 850 – The MA 850 is a wireless LAN module that provides secure and centralized connections for 802.11a/b/g Access Points and distributes the wireless services over the same coax and broadband infrastructure as the voice services. All services are combined and distributed through the same antenna broadband infrastructure. 2000 Lite which can support two RU 2000 modules (and MA 1200 add-on units) may be used as an entry point for sites that support a minimal number of operators. This installation is future safe and can easily be upgraded to support additional operators or services (using MA Remote Cabinet configuration). To provide optimum coverage at all times and monitoring and control of all system elements from a central location MA provides the following devices: • MA Radio Interface Units (RIUs) – The RIUs provide interfaces for up to three BTS/BDA signals, and automatically adjusts the output signal in respose to input signal level in order to provide optimal coverage. • MA 410/430 controllers – The controllers enable remote monitoring of the system elements from a single location via advanced intuitive GUI. Installation and Configuration Guide Introduction The following figure illustrates a MA 2000 system that includes MA 410/430 controllers, RIUs and is based on a Remote Cabinet configuration. This type of installation may be powered locally or remotely form a single power and UPS source. The system in this example distributes five services: three from one operator, through one RU and a 1200 add-on module, and two additional services through a second RU. Figure 1-2. Example of a MobileAccess 2000 System Installation and Configuration Guide Introduction 1.3 MA 410/430 Remote Management The MobileAccess (MA) Network Management System (NMS) provides complete site coverage and network management. It can be used to provision coverage that can compensate for changing loads. It also provides real-time monitoring, control and diagnostics capabilities for MobileAccess devices from a single location. NOTE: The MA NMS System is fully described in the MA NMS System Configuration and Operation Guide. The MA NMS system consists of: • • MA 410/430 Controller – The controller provides the interface between the system elements and the management and control mechanism. Two controller models are available: • MobileAccess 410™ – enables management of the connected devices through a local or point-to-point dial-up connection. It can be remotely managed through a connection to the MobileAccess 430 controller. • MobileAccess 430™ – enables management of all connected elements and all connected MA 410 controllers and the corresponding elements. Supports SNMP (Simple Network Management Protocol) over TCP/IP connection. • MA 430 may be managed through the Network Operator Center (NOC) through Manager of Mangers element such as HP OpenView via SNMP. MCT – a Java based GUI application provided with both controllers. The MCT is used after the installation procedure to adjust MobileAccess devices according to the installation site characteristics in order to optimize coverage for the site. The application is installed and ran from a computer that is connected either locally or via remote dial-up modem to the controller site to be adjusted or monitored. • MobileAccess Manager™ – a Java based GUI software application that provides enhanced monitoring and control capabilities for all your MA 430™ sites from a single location; each site can consist of a standalone MA 430 controller, or a MA 430 controller in a Master topology with a number of MA 410 controllers connected as slaves. The MobileAccess Manager application is not supplied with the controller – it is purchased separately. The MA NMS application is installed on a server and is accessed from any client by connecting to the server from any Web Browser with enhanced Java VM capabilities. MA NMS manager provides the following features and capabilities: • Remote SNMP management from a single location • Client/server management capability over a TCP/IP network with enhanced monitoring and control capabilities • Intuitive GUI that enables end-to-end fault sourcing from RIU to antennas. The GUI includes: • System status at a glance through multi-color tree with upward propagation of fault indications Installation and Configuration Guide Introduction 1.4 • Graphical view of system elements including LED status displays and auxiliary connections • Multi-color event monitoring display • RF Connections MobileAccess Models Table 1-1: MobileAccess™ Remote Cabinet Models MobileAccess Remote Cabinet 2000-RC-RP Remote Cabinet, remote powering – integrated DC power supply 2000-RC-LP Remote Cabinet, local powering 2000 - MINI-ENC 2000 system supporting two modules (external to the system) (2000 Lite) Table 1-2: MobileAccess™ BU Models MobileAccess Universal Base Units (1000, 1200, 2000 support) WB-B8U Wide Band Base 8 Unit supporting 8 RUs WB-B4U Wide Band Base 4 Unit supporting 4 RUs Table 1-3: MobileAccess™ 2000 RU Models with Add-on Capabilities MobileAccess 2000 RUs (ready for add-on units) 2000-IDEN-PCS Dual Band iDEN/PCS 2000-CELL-PCS Dual Band Cell/PCS 2000-GSM-DCS Dual Band Cell/DCS 2000-SMR-PCS Dual Band SMR-Paging 900/PCS 2000-CELL-DCS Dual Band Cell/DCS 2000D-CL-M-DCS4 Multi-operator/DCS 2000-GSMO-DC GSM/DCS 2000-GSMO-DCS GSM Orange/DCS Table 1-4: MobileAccess™ 1200 Add-on Models MA 1200 Add-on 1200-PCS-AO Add-on RHU - PCS service 1200-UMTS-AO Add-on RHU - UMTS service Installation and Configuration Guide Introduction Table 1-5: MobileAccess™ Controller Models Network Controller 410 Network Controller – Serial Interface (dial-up) 430 Network Controller – Ethernet/IP Interface Table 1-6: MobileAccess™ Management System Network Management System NMS-SW-SERVER GUI and server S/W package (one per site) NMS-SW-MFEE NMS annual S/W maintenance fee (per 430-CTLR) Table 1-7: MobileAccess™ RIU Radio Interface Unit RIU-IM Radio Interface Unit RIU-BTSC-CELL BTS Conditioner for Cellular RIU-BTSC-IDEN BTS Conditioner for iDEN RIU-BTSC-PCS BTS Conditioner for PCS RIU-BTSC-SMR BTS Conditioner for SMR-Paging RIU-BTSC-GSM BTS Conditioner for GSM 900MHz RIU-BTSC-GSM-O BTS Conditioner for GSM 900MHz for Orange RIU-BTSC-DCS BTS Conditioner for DCS 1800MHz RIU-BTSC-UMTS BTS Conditioner for UMTS 2100MHz Installation and Configuration Guide 2 Site Preparation 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: 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. This includes the MA 850, 802.11 Access Points, cabling and other voice service distribution systems that are relevant to the specific installation. 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). Each length of cable from the risers to each antenna must be concealed above 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. Installation and Configuration Guide Site Preparation 2.3.2 2.3.3 Fiber Optic Rules • Use only single mode fiber for indoor applications. • 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 like the Cletop. • 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 ½”, 50ohm, male-to-male N-type, (6-7dB for 1Ghz, 11dB for 2Ghz) for connecting to RU and RHU ports. • Use coax RG223, 50ohm, male-to-male N-type for connecting RF side from the Base Unit to the BTS/RBS side. • When using the MobileAccess™ system in an environment in which other indoor coverage systems are installed, pay special attention to the isolation between antennas (distance must exceed 2 meters). • Use special attention while bending coax cables, the bending radius must not exceed the coax specifications. • Use any antennas suitable to the desired frequency. • Use VSWR meter (Site Master) 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. Installation and Configuration Guide Site Preparation 2.4 Power Consumption, Connections and Power Supplies 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. 2.4.1 Power Consumption of Units Table 2-1.

Each cabinet (2000 Lite) can typically cover a floor of up to 30,000 sq ft. • Fiber optic cable - Bundled fiber is terminated into the Base Unit in the main communication room. This fiber is then ran vertically throughout the building through a communication shaft or vertical riser. Individual fibers terminate on floors into a slice box. The splice box couples the installed fiber into the remote units. Not all fibers will terminate on a single floor. A portion of the vertically ran fibers will terminate on each floor. Fiber cables should be purchased with enough spare fibers terminated on each floor to support future growth. NOTE: For example, for three remote units, six fibers are required. However, to allow for future upgrades, it is recommended to install additional optic fibers to be connected to additional RUs. • For remote power supply configuration - single source power cable – a single cable bundle is ran from the main communication room. This bundle will consist of a number of 18 gauge wire pairs (typical). 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. Power is typically less than 100 watts. 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 within 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. 14 or 16 gauge wire offers less impedance than 18 gauge wire. While this wire is more expensive the nominal price increase far outweighs the purchase of additional hardware. • 10 On each floor, the antennas are connected to the Remote Cabinet or 2000 Lite system using coax cables.

The individual system elements and connections are described in the Chapter 4. 3.2 Communication Room Installation NOTE: Usually, each operator installs the equipment that supports their services in a separate rack. It is recommended to install the following MobileAccess system modules in a 19” rack in the communication room • RIU 3U • BU 1U • MobileAccess 410/430 controller 1U • Fiber Optic patch panel and splice tray • Power supply/supplies (MobileAccess – 3U for each unit; units from other manufacturers may vary in size) Verify that the rack height can support all the units to be installed, where you may also want to consider future expansions. 12 Installation and Configuration Guide Rack and Cabinet Installations The following image displays the recommended physical deployment of the MobileAccess elements in the rack in order to facilitate and simplify the cabling connections. The configuration is for a single operator. If the site is serviced by more than one operator, each operator often installs their equipment in a separate rack. Note that the MobileAccess 410/430 controller is at eye level to provide an easy view of the LED indicators and LCD display and easy access to the local and remote monitoring connections.

Since there are 24 floors, then 24 RCs will be needed: one on each floor. Each RC will house two RUs. In addition, the following equipment will be installed in the main communication room: • Six BUs – three to support 24 RCs for Cellular/PCS RU, and three additional BUs to support iDEN/PCS RU • Two MA 410/430 controllers to support the BUs: one MA 430 controller configured as Master, and one MA 410 controller configured as slave. NOTE: This example shows a Master/Slave configuration, but if a network is easily available, two MA 430 controllers may be directly connected to the network and monitored from a single location. • RIU – to interface to the BTS/BDA Installation and Configuration Guide 13 Rack and Cabinet Installations Coax iDEN Coax Cellular RIU RIU PCS Coax RS-485 BU Coax Coax BU BU RS-485 BU Coax BU RS-485 RS-485 Dry Contact Alarms Output RS232 MA 430 Master BU MA 410 Slave Coax connections to external devices Figure 3-2.

Each site consists of an 8-floor building, requiring 8 RCs per building (one on each floor). Each RC will contain two dual-band RUs. The following equipment is required in the main communication room of each building: • Two BUs – each BU distributes a high-band and low-band signal from a dedicated operator to eight RUs (housed in eight separate RCs – one on each floor). • One MA 430 controller configured as Master in the Main building, and two MA 410 controllers configured as slaves in the Remote buildings. • MA 300 Main in the main building, and MA 300 Slave in each of the remote buildings. The MA 300 units extend the RF signal from the Main to the Remote buildings over a single strand of fiber. Uplink and downlink signal are placed on the single fiber at 1310 and 1550 respectively.

The procedure varies slightly depending on whether the RC is an integrated or external power supply model. The following sections describe both procedures. 3.3.1 RC 2000 Wall Mount Installation ATTENTION: The following instructions apply to an installation on a concrete wall. For any other type of wall, contact MobileAccess. The wall installation 2000 Remote Cabinet is supplied with a plate that is to be mounted on the wall and a bracket that is assembled on the rear of the MA 2000 system.

MA 2000 System Wall Mount 16 Installation and Configuration Guide Rack and Cabinet Installations Mount the RC on the wall as follows: NOTE: For installations that include an MA 850 system, refer to section 3.4. 1. For integrated power supply configurations only (for other configuration grounding is optional), connect the cabinet GND according to Wall Mount RC Grounding section 3.3.2. 2. Using the plate as a guide, drill four holes for concrete anchors. Insert four concrete anchors (McMaster-Carr catalogue number 92403A200, or equivalent). 3. Mount the Plate on the wall. Carefully and thoroughly fasten the anchors to the wall. 4. Assemble the Bracket onto the rear of the Remote Cabinet using the supplied screws. 5. Lift the MA 2000 RC and guide the rear ledge of the assembled bracket onto the plate bracket. 6. Secure the RC Bracket to the Plate on the wall, using the four screws. 3.3.2 Wall Mount RC Grounding NOTE: This procedure is only necessary for wall mount integration power supply configuration (for other configurations this procedure is optional). MA 2000 provides two options for grounding the cabinet: • At the rear of the unit • On the power connection panel inside the unit Figure 3-6: Grounding Located at the Rear of the Unit Installation and Configuration Guide 17 Rack and Cabinet Installations 3.3.3 RC 2000 Rack Mount Installation The MA 2000 RC Rack Mount model is supplied with the required brackets already assembled to the sides of the cabinet as illustrated in the following figure. Simply, mount the MA 2000 RC in the rack and secure with the supplied screws. Rack brackets Figure 3-7 .
