1 11 IInnttrroodduuccttiioonn 1.1 About MobileAccess™ 1000 MobileAccess™ 1000 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 and distributing them through a common antenna infrastructure. Figure 1-1. MA 1000 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 1000 system provides entry level solutions that can be upgraded using the same infrastructure to support additional services as required. Wireless 802.11/a/b/g coverage may be integrated into the MA 1000 system using the MA 850 remote module (that supports wireless LAN service distribution).
MA 1000 Installation and Configuration Guide 2 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 1000 system enhancement solutions: • 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 1.1.1 Features • 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 • All services are distributed through a single coax and antenna infrastructure • All active components are located in the communication closet/room • Modular, scalable and future-safe – additional remote units can easily be installed • Support for remote monitoring through MA 410/430 controllers • Eliminates RF interferences occurring where multiple antenna systems are used to serve multiple services • Enables fast deployment for corporate enterprises, property owners and WSP’s of new services • Reduces tenant disruption • Low power required by the system eliminates the need for high power BTS/RBS, reducing operator expenses • Provides both local and remote monitoring and control capabilities • Software programmable parameters including output power, AGC (on/off and levels), and system gain • Real time component setting capabilities for optimal performance (aging, temperature, optical connectors, etc.,)
MA 1000 Installation and Configuration Guide 3 1.2 System Architecture The MA 1000 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 Hub Units (RHUs) 1000 – The MA 1000 performs the RF to optic signal conversion at the antenna side for up to two services corresponding to the RHU model. A third service can be added by connecting an add-on remote hub unit (MA 1200) to the RHU 1000. • 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. 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. 1.3 Configuration Options The MobileAccess™ 1000/1200 system includes three basic configuration options: A) Basic configuration The Base Unit drives a single or dual band, MobileAccess™ 1000 RHU. The dual band RHU consists of a low band service (cellular 800, iDEN, Paging, or GSM 900) and a high band service (PCS 1900 or DCS 1800). Figure 1-2. MobileAccess 1000 Basic BU – RHU Configuration
MA 1000 Installation and Configuration Guide 4 B) Using the MobileAccess 1200 add-on unit to provide an additional service A MobileAccess™ 1200 add-on unit can be connected to a MA RHU 2000 unit to provide a third service. The add-on unit can be Cellular, PCS, UMTS, 3G, or any future service. Figure 1-3.

MA 1000 Installation and Configuration Guide 9 22 SSyysstteemm EElleemmeennttss This chapter describes each of the system elements, and their individual connections. It can be used as reference to verify the connections of each module or to upgrade your system. 2.1 Remote Modules The Optical to RF conversion of each service at the individual building floors is performed by remote units corresponding to the service types. These consist of MA 1000 RHUs and in addition, may include MA 1200 add on modules and MA 850 modules. The configurations depend on the requirements of the site and the supported services. The following sections describe each of the system elements. NOTE: The connections as they relate to the MA 1000 system are described in Chapter 4 - System Installation. 2.1.1 MA 1000 RHUs Each RHU supports two different services (one high-band and one low-band). All RHUs are add-on ready, meaning that their optic interface and control functionality can support a third (high-power) service through the connections of a MA 1200 Add-on module (see section 0). Each RHU 1000 is connected to the corresponding BU (located in the communication room) through a fiber optic connection. Remote monitoring is provided through the BU connections to the MA 410/430 controller (see section 2.4). The RHU 1000 services, MA 1200 add-on service and data services (provided by MA 850 - 2.1.3) at each location are combined and then transmitted over a common infrastructure to strategically placed antennas.

MA 1000 Installation and Configuration Guide 16 2.2 Radio Interface Unit (RIU) The RIU is an operator dedicated unit that interfaces to up to three BTS sources and automatically adjusts the signal output according to changing environmental conditions in order to provide optimal coverage for the site. The RIU is remotely monitored and managed. Each RIU can support up to three BTS Conditioner (BTSC) sub-modules, where each sub-module provides interface to a BTS or BDA of the same type of service. Each RIU can be connected to four 8-port Base Units (real panel connections) or to eight 4-port Base Units. Additional BUs can be supported by using splitters and combiners connected to the front panel Expansion connectors. The following figures shows an RIU with three BTSC sub-modules. Figure 2-7. RIU Note: All connections are via RG223 coax cables with 1/2" N-type male connectors ATTENTION The RIU is factory set to 0dB gain on the uplink and downlink. In order to operate properly, an ADJUSTMENT process is required in the field. Any unused input and output connectors MUST be terminated with 50 ohms – otherwise the ADJUSMENT procedure results may be affected.

MA 1000 Installation and Configuration Guide 18 2.2.1.2 RIU Rear Panel The rear-panel provides all the connections on the BTS side and on the BU side as well as connections to the MobileAccess 410/430 controller and the power connection. Two types of BTS side connections are available for each BTS conditioner: simplex and duplex. Figure 2-9. RIU Rear Panel showing the RF Connection 2.3 MA Base Units The BUs (Base Units) perform RF to optical conversion of the signal on the BTS/BDA side. Each can support up to two services (provided by the same operator). Two models of MA BUs are available: four-port unit – supporting four RHUs, and eight-port unit supporting up to eight RHUs. The RHU models correspond to the services supplied through the BUs. The BU (and all the corresponding remote units) may be remotely monitored and managed via the MA NMS (Network Management System). The BUs are usually installed in the telecom room adjacent to the BTS/BDA signal source. RF ports on the rear panel provide interface to the BTS side (through connection to RIU or passive interface), while optic ports on the front panel provide interface to the RHUs (Remote Units). This following sections describe the MA BU front and rear panels, including indicators and connectors. BU connections; one UL and one DL connection for every group of four ports (single OPTM) on the BU. Power MA Controller connection BTS/BDA simplex connections BTS/BDA duplex connections

23 33 SSiittee PPrreeppaarraattiioonn 3.1 Infrastructure Preparation This following installation rules are based on the assumption that site survey and installation planning (including power requirements) have been completed. 3.2 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. 3.3 Coaxial Cable Connections 3.3.1 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.
MA 1000 Installation and Configuration Guide 24 3.3.2 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 (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. 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. 3.3.3 RF Rules • Use coax ½”, 50ohm, male-to-male N-type, (6-7dB for 1Ghz, 11dB for 2Ghz) for connecting to RHU and RHU ports. • Use coax RG223, 50ohm, male-to-male N-type for RF connections from the BUs to the BTS/RBS and to the RIU. • 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 RHUs in the remote communication rooms • Terminate all unused RHU and RIU ports with a 50 ohm load
MA 1000 Installation and Configuration Guide 25 3.4 Power Consumption, Connections and Power Supplies 3.4.1 Power Safety Instructions SAFETY WARNINGS • When installing or selecting the power supplies: • Be sure to disconnect all power sources before servicing. • Battery replacement in units - only the MA 410/430 controller has batteries. MA 410/430 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 – use only the power cords supplied with the units • Install external over-current protective devices for the system according to the requirements described in section 3.4.3. 3.4.2 Power Consumption of Units Table 3-1. MobileAccess™ Power Requirements Unit Type Voltage Input Typical Power Consumption Maximum Current Consumption Remote Unit 1000 20 to 48VDC 25W 1.25A Add-on Unit 1200 25 to 48VDC 50W 2.0A RIU 20 to 48VDC 12W 0.6A Base Unit 20 to 48VDC 14W 0.7A 410/430 Controller 20 to 48VDC 10W 0.5A MA 850 20 to 48VDC 20W 1.0A
MA 1000 Installation and Configuration Guide 26 3.4.3 Circuit Breakers Install fuse protections for the system according to the following criteria: • The following system elements require external fuse protection: RIUs, BUs, and 410/430 Controllers. • Referring to Table 3-1, calculate the required fuse protection. • Example: a set of three elements consisting of a BU, RIU and MA 410/430 controller requires a 2A circuit breaker. 3.4.4 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.

MA 1000 Installation and Configuration Guide 27 3.5 Installation Conventions Some of the basic installation conventions are listed below for the MA 1000 system: • Base Units – are usually concentrated in the same location, most often in the main communication room. • Remote Hub Units usually placed in the communication shaft or closet of a corresponding floor so they can be easily located. Each RHU 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 location 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 upgrades, it is recommended to install additional optic fibers to be connected to additional RHUs. The following figure illustrates fiber optic routing sufficient to cover 21 floors: each group of strands can cover three floors as illustrated below, with two strands to spare. The first group of strands coves floors 1, 2 and 3; the next group will cover floors 4, 5 and 6 through an additional splice box. Figure 3-1. Illustration of Fiber Optic Routing
MA 1000 Installation and Configuration Guide 28 • 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 RHUs using coax cables.
MA 1000 Installation and Configuration Guide 29 44 SSyysstteemm IInnssttaallllaattiioonn 4.1 Overview This chapter describes how the communication room and remote locations are installed. The individual system elements are described in Chapter 2. In order to describe the installation process clearly, it will be described as consisting of two logical parts: A. Telecommunications room – installing the RIUs, BUs, MA 410/430 controllers, and the required passive equipment in the telecommunication room close to the RF signal source. This installation may differ between single and multi-building topologies. B. Remote locations – RHU and Add-on installations and connections. These are usually wall mounts. The installations for two basic topologies are described in detail: for single building and for multi-building. By understanding the two generic installations you will be able to address any variations in system deployment. NOTE: For installations that include the MA NMS: Once the installation has been completed, it can be verified using the MCT application (NMS User’s Guide) and the devices monitored using the NMS Manager (NMS User’s Guide). 4.2 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)
MA 1000 Installation and Configuration Guide 30 4.2.1 Rack Installation General Instructions Verify that the rack height can support all the units to be installed, where you may also want to consider future expansions. Figure 4-1 shows the recommended physical location 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: 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. Figure 4-1: Recommended Order in the Communication Room Rack 4.2.2 Rack Installation Safety Instructions Review the following guidelines to help ensure your safety and protect the equipment from damage during the installation. • Only trained and qualified personnel should be allowed to install or replace this equipment. • Verify that ambient temperature of the environment does not exceed 50°C (122°F) • To maintain a low center of gravity, ensure that heavier equipment is installed near the bottom of the rack and load the rack from the bottom to the top.

MA 1000 Installation and Configuration Guide 31 • Ensure that adequate airflow and ventilation within the rack and around the installed components so that the safety of the equipment is not compromised. It is recommended to allow for at least about 2 cm of airspace between devices in the rack. • Verify that the equipment is grounded as required – especially the supply connections. 4.2.3 Single Building Rack Installation This section provides an example of a single building main communication room installation for a 24-floor building with Cellular and PCS coverage. Since there are 24 floors, then 24 MA RHUs are required – one for each floor. In addition, the following equipment will be installed in the main communication room: • Three BUs – to support 24 RHUS • One MA 430 controller for monitoring • One RIU with Cellular and PCS BTSCs – to interface to the BTS/BDA Figure 4-2. Example of Single-building Topology Communication Room Installation
MA 1000 Installation and Configuration Guide 32 4.2.4 Multi-Building Rack Installation Figure 4-3 provides an example of a multi-building solution which distributes two bands over a main site and two remote sites. Each site consists of an 8-floor building, requiring 8 RHUS per building (one on each floor). The following equipment is required in the main communication room of each building: • One BU – each BU distributes a high-band and low-band signal from a dedicated operator to eight RHUs (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.

39 55 AAppppeennddiixx II:: OOppttiiccaall TTeesstt PPrroocceedduurreess 5.1 General Two parameters are of prime importance when testing optical cables or jumpers for use with Mobile Access products: • Optical Loss – the difference between the optical power at the input and output of an optical cable. It must be measured (usually in dB units) at 1310 nm. The maximum allowable loss should be < 0.5 dB/km for Single Mode (SM) cables and < 0.5 dB for every mated pair of connectors. • Optical Backreflection – the percentage of light backreflected from the fiber input (dB units). The maximum allowable backreflection should be < –55 dB for all jumper cables. The methods to test these parameters will be described below. 5.2 Optical Loss Testing This section describes the optical loss testing of a Single Mode Cable with SC/APC connectors at each end. 5.2.1 Required Test Equipment • 1310 nm Stabilized Laser Source • 1310 nm Optical Power Meter • Two Fiber Optic Test Jumpers with SC/APC connectors at each end • Two SC/APC Adapters
MA 1000 Installation and Configuration Guide 40 5.2.2 Test Procedure 1. Set up the Laser Source, Optical Power Meter, and Test Jumper as shown below. Figure 5-1. Set Up 2. Record reading as P1 in dBm units. 3. Serially connect the second Test Jumper as shown below. Figure 5-2. Serial Connection of Second Jumper 4. Record the Power Meter Reading as P2 in dBm units. 5. Calculate Loss L12 according to the equation: L12 = P1 - P2 6. If L12 is lower than 0.5 dB continue to Step-7; otherwise replace these test cables and repeat from Step-1.
MA 1000 Installation and Configuration Guide 41 7. Disconnect connectors B and C. Connect the Cable Under Test (CUT) between connector B and C as shown below. Figure 5-3. Connecting CUT 8. Record Power Meter reading as Pcut in dBm units. 9. Calculate Cable Loss Ldut from the equation Lcut = P2- Pcut. 10. The maximum allowable loss should be < 0.5 dB/km for SM cables and < 0.5 dB for every mated pair of connectors. 5.2.3 Example Testing a 50 meter cable with SC/APC connectors at each end. • P1 = -1dBm • P2 = -1.5dBm • L12= P1 – P2 = -1dBm - (-1.5) = 0.5 dB Conclusion: the test cables are of sufficient quality to continue testing. • Pcut = -2dBm • Lcut = P2 - Pcut= -1.5dBm - (-2dBm) = 0.5 dB This is acceptable since a mated connector pair was added along with the CUT and a loss of -0.5 dB is allowed for every mated pair of connectors. 11.

Refer to the following figure for port definitions of the Fiber Optic Coupler. The coupler is symmetrical but for our purposes, each port should be identified as shown in Figure 1-4. Figure 5-4. Port Identification 2. Measure the loss from port I1 to O1 according to the insertion loss method described in the previous section. This loss will be referred to as LI1O1. It should be approximately 3.5 dB. 3. Measure the loss from port O1 to I2 in a similar manner. This loss will be referred to as LO1I2. It should also be approximately 3.5 dB. 4. Calculate Total Loss, TL where TL= LI1O1 + LO1I2. TL should approximately 7dB. 5. Adjust the laser output power in dBm to the same value as TL. For example, if TL = 7dB, adjust the laser output to 7 dBm.

The power meter readings should be < –58 dBm; otherwise, clean connector O1 and measure again. 10. Connect the cable under test to connector O1. 11. Record Power Meter Reading as Backreflection, BRcut, of the cable under test. The power is measured in dBm units. This is the same value as the backreflection. For example, if the power meter shows –58 dBm, the backreflection is –58 dB. The maximum backreflection from the SC/APC connectors should be < –57 dB. Long cables will have a higher BR since the cable itself reflects a small amount of light. This small amount can grow to a considerable amount over a long length of fiber. To factor out this cable backreflection, perform a mandrel wrap on the cable adjacent to the connector under test and perform all measurements with the mandrel wrap.
