1.0 INTRODUCTION

1.1 Overview The OneBase Cell Extender System is a high-power, mixed-mode RF front-end equipment solution which provides signal amplification and conditioning for both uplink and downlink cellular base station signals (Figure 1). It is a highly modular design, consisting of a minimal set of unique field-replaceable units, capable of being configured and scaled for a variety of system level capacities and air interfaces including TDMA, GSM/EDGE, CDMA, WCDMA and analog air interfaces. Architecture for the system is highly configurable and can be arranged for a variety of RF front-end applications. Fitting into an existing BTS between the BTS radios and the antennas, the OneBase Cell Extender system is capable of doubling the transmission radius of an antenna in some configurations. Such a large RF output requires up to 400 Watts of RF power and a large DC power source to produce this large RF power output. For this reason, the OneBase components (either indoor or outdoor) must be in a secure area accessible to only qualified technicians.

Figure 1: The OneBaseCell Extender System provides cell site amplification and

fits between the existing BTS and the antennas.

1.2 Modular Design Advantages The design advantages of the OneBaseCell Extender System include: 1. Enabling the expansion of existing cellular base station systems by adding carriers

without adding antennas. 2. Increasing the power of existing carriers, thereby increasing the cell radius.



3. Converting a high-power, lossy-combining base station to a multi-carrier base station, thereby allowing additional expansion without further changes to the antenna path.

4. Allowing for modulation format changes without the need for reconfiguring or additional hardware. 1.3 Product Improvements Andrew Corporation reserves the right to make product improvements. Therefore, modifications that impact this manual will be incorporated into later revisions of this manual.

1.4 Safety Precautions

All of the following Safety Precautions must be observed during the entire installation and operation of the Andrew Corporation OneBaseCell Extender System. 1.

2.0 SYSTEM DESCRIPTION

2.1 Components The OneBase Cell Extender System can be built with an extensive variety of configurations using five types of modules as the building blocks of these configurations. The modular-designed OneBaseCell Extender System consists of the following major components: HARDWARE:

Housings: o Indoor Frame: Capacity up to three subracks. o Outdoor Full-Size Cabinet: Capacity up to three subracks. o Outdoor Mini-Cabinet: Capacity one subrack

. Subracks: Capacity up to four MCPAs.

Modules: Modules fit into the subracks.

o RF Interface (RFIM) Module o Filter Modules o Multi-carrier Power Amplifier (MCPA) Modules o Input Tray Modules (Duplexed and Simplexed) o Switched Combiner Modules (SCM)

Power Distribution Panel (PDP)

Alarm Interface

SOFTWARE:

Web Maintenance Terminal Graphical User Interface (GUI) Configuration and Monitoring Software

Each subrack may be arranged to service one-to-three cell sectors and can hold all necessary equipment for insertion into the BTS-to-Antenna path and the following modules:

One RF Interface (RFIM) Module Up to three Filter Modules Up to four Multi-carrier Power Amplifiers (MCPA) One Switch Combiner Module (SCM) or an Output Cable Assembly (OCA) Up to 6 Input Tray Modules One Power Distribution Panel (PDP) Module



Selection of the appropriate interface modules and filter units allows this system flexibility for use in any cellular system. Each OneBaseCell Extender System is specifically designed for a specific cellular system by using the correct combination of modules and the correct electrical and RF configuration of these modules. The components of the OneBaseCell Extender System are electrically connected with a combination of blind mate rear connections and front panel connections to optimize flexibility and ease of maintenance. 2.2 Housings Housing configurations for both indoor and outdoor applications are arranged within open Indoor Frames or closed Outdoor Cabinets. Dimensions and configurations are given in this section for the indoor frame and several versions of outdoor cabinets. Examples of these two types of assembled housing configurations are the following:

Indoor Frame (Dual Band, Three-sector NRS System)

Outdoor Full-size cabinet (Three-sector 4:1 Combining System)

2.3 Subracks The subrack serves as a mounting platform for all the modules. Because they require additional effort to remove, subracks are not listed as a module. However, the subrack can be removed and shipped back to the factory for repair if needed. If the Power Distribution Panel (PDP) fails, it is recommended that the subrack be shipped back because the PDP is generally not a field-replaceable module. Frames and cabinets can hold up to three subracks. Frames contain the subracks for indoor applications, while cabinets contain the subracks for outdoor applications. The MCPA Modules are vertically arranged and blind-mated to their RF and DC/control interfaces in the rear of the subrack. The RF Interface Module (RFIM) is also vertically arranged and is located to the right side of the MCPA modules. The Filter Modules are situated at the top portion of the subrack mounted either vertically or horizontally. The filters interface to the SCM through blind-mate N connectors. The various subrack configurations are as follows:

2.4 Modules The OneBaseCell Extender System consists of the following modules:

RFIM Modules Filter Modules MCPA Modules Input Tray Modules Combiner Modules

The exact combination of modules depends on the application. 2.4.1 RF Interface Module (RFIM) The RFIM is the system controller. Most subracks have an RFIM. On those subracks that do not have an RFIM, the Multi-Carrier Power Amplifiers run autonomously, and redundancy is not supported. The RF Interface Module (RFIM) has the following functions and features:

Subrack main controller 800 2000 MHz wideband operation, supporting dual-band subracks Input signal combining of various air interface signals and coherent signal

splitting of the composite RF signal Fine gain adjustment capability at the common input signal to the PA Modules Transmit Diversity Redundancy (TDR) switching and control functions including

gain compensation of the transmit path carrying 2x capacity DC power conditioning and regulation for internal circuits, Filter Module

electronics, Switch Combiner Module circuits/relays, and Alarm Consolidation Unit circuits.

Control and monitoring of the Switch Combiner Module VSWR and RMS input level detection circuits Remote monitoring of subrack operation via Ethernet port



Figure 15: RFIM Module and diagram--4x2 configuration.



2.4.1 Filter Modules The Filter Modules perform the output filter duplexing functions for the MCPA system. It is connected to the output of the Mutli-carrier Power Amplifier and can filter the received signals. Some Filter Modules are customized to handle site-specific interference issues. The Filter Module includes VSWR detector circuits. The VSWR detector circuits in the Filter Module report problems to the RFIM. All anticipated system configurations are realized using one (or two) standard filter designs as building blocks, or simple derivatives, of these primary designs Filter modules have the following functions and features:

Transmit and receive filters in a duplexed configuration Low-pass transmit clean-up filter on duplexed branch LNA circuits (optional) Dual-directional couplers VSWR detector circuits Bias Ts for tower mounted amplifier (TMA) support 40 dB coupled port to monitor real time transmit power

2.4.3 Multi-carrier Power Amplifier (MCPA) Modules

The MCPA module is the heart of the OneBase Cell Extender system. This module boosts the BTS transmission signal. Using 27 VDC, the MCPA produces 135 Watts of power to the antennas. The unit contains integral cooling via a fan-tray assembly. The MSA1900-135 and MSA850-135 provide linear amplification of multi-carrier, mixed-mode signals in the cellular and PCS frequency bands, respectively. The 850 MHz band MCPA (MSA850-135) and 1900 MHz band MCPA (MSA1900-135) have the following specifications.

Table 3: Specifications for 850 MHz band and 1900 MHz band MCPAs.

2.4.4 Input Tray Modules: Simplex and Duplex The Input Tray module provides the signal and cabling interface between the BTS antenna ports and the RFIM. The Duplex Input Tray module can accept duplexed (Tx/Rx) BTS interfaces. The Simplex Input Tray accepts only simplexed (Tx) BTS interfaces. The functions and features of the RF Input Tray Modules are as follows:

Attenuation of transmit (Tx) path signals and re-duplexing of receive (Rx) path signals

Duplexed and simplexed versions for each frequency band (850 MHz cell band

and 1900 MHz PCS band) Fully front-accessible for interconnections Mount to either side of subrack via captive thumbscrews. Input Tray Modules

are not slot specific Free air convection cooled Weight: 12 pounds, maximum Size: 9.05 inches x 9.05 inches x 3.31 inches Power Handling: 40 Watts maximum per port, 65 Watts total per tray Support for Tower Mounted Antennas (TMAs)



Figure 18: Simplexed and Duplexed Input Tray Modules

2.4.5 Switch Combiner Modules (SCM) The Switch Combiner Module (SCM) provides active combining of paralleled MCPA modules. The SCM can disconnect an empty MCPA slot or a failed MCPA module on the subrack without incurring additional power loss. The RFIM controls the combiner module switches. If an RFIM is not present on the subrack, the MCPA modules do not work in parallel, and each MCPA controls the relevant switches based on MCPA faults. Switch Combiner Modules (SCMs) have the following functions and features:

Provide active combining of paralleled amplifiers Disconnects empty slot or failed MCPA modules within a subrack without

additional power loss

Simplexed Input Tray Module Duplexed Input Tray Module

Figure 19: 1900-Band 4x2 Configuration Switch Combiner Module (SCM).

2.5 Power Distribution Panel (PDP) The Power Distribution Panel (PDP) is permanent hardware assembled at the factory on the subrack. The PDP arrives at the cell site already installed in the subrack . The PDP is generally not field-replaceable, except by specially qualified personnel. If the PDP fails, it is recommended that the entire subrack be returned to Andrew Corporation for repair. The following are the functions and features of the Power Distribution Module:

Power Distribution Panel (PDP) manages the DC interface to subrack,

distributes power to active components in subrack

Integrated circuit breakers (recessed rocker style) for each MCPA module and RFIM unit



Four DC feeders power each subrack

Soft start, in-rush current limiting circuitry (one for each Amplifier) Bulk capacitors hold DC Bus voltage sag to specifications during RF Amplifier

programmed power excursions

Auto-shutdown circuitry if PA is not mounted properly in subrack

Not considered a plug-in unit, though may be replaced in the field with properly trained personnel

Figure 20: Power Distribution Panel (PDP)Front view (left) and Rear View (right).

2.6 Alarm System

The alarm system is designed to help quickly locate both the severity of a problem and the location of a problem. Alarms fall into three main categories as indicated in the following table.



Table 4: OneBase Cell Extender System alarm categories.

The alarms are also accessible at remote locations by either connecting to the ethernet port in the RFIM or connecting to one of two terminal blocks (one on the top of the frame or one on the rear of the middle subrack). Specific location and description of these terminal blocks are as follows: LOCATION 1: A two-row, 38-screw connection terminal block is located at the top of the frame. This terminal block has alarm wire connections for three subracks. When a subrack is in a 3+1 configuration and services three sectors (usually there will be only one subrack in this case), Critical alarms are provided for all three sectors at the terminal blocks. This is also the case when a subrack is in a 4x2 configuration. When a subrack is in a 4x1 configuration and services only one sector (usually there will be three Subracks in this case), Minor, Major and Critical alarms have connections at these terminal blocks for each Subrack. LOCATION 2: The other access to dry contacts is an individual set of wire connections to each MCPA alarm set on the rear of the Subrack. There are Minor, Major and Critical alarms for each MCPA (up to four). The alarms for the individual MCPAs are accessible on the lower middle rear of the Subrack on two vertical, two row screw terminal block



2.7 Web Maintenance Terminal Graphical User Interface (GUI) Software Embedded in the RFIM is the Web Maintenance Terminal graphical user interface (GUI) software for use in monitoring, updating, diagnosing, debugging, fine-tuning, troubleshooting, and controlling the entire OneBaseCell Extender system and network configuration. It is noted that system set-up and operation does not require the use of the Web Maintenance Terminal software, because the RFIM comes from the factory configured with software supporting the ordered system. In addition, the default settings within the MCPA for system gain and configuration are adequate for most installations. However, if fine-tuning of gain or internal parameters is desired, or if field changes are made to the configuration, the Web Maintenance Terminal software can be used.

. Figure 21: Accessing the RFIM Web Maintenance Terminal (GUI) software is easily

done by connecting a laptop to the RFIM Network port via an Ethernet cable.

CAT5 Ethernet Cable



There are two levels of access available for service providers as follows:

Operator Access. Operator Access allows access to read the diagnostic information and allows minimal operational parameter changes to the system

Administration Access: Administration Access allows access to the

information and allows total access to make detailed changes to the operational parameters of the system.

2.8 Assembled Systems 2.8.1 Configurations The modular components of the OneBase Cell Extender system provide outstanding ability to create several MCPA configurations. These configurations can be made to meet extensive user applications. The following drawing shows the flexible capability of these modular components to create application specific systems.



2.8.2 System Level Specifications The modular combination of modules for a specific application results in a system which has extraordinary capabilities. These capabilities are best understood by examining the system level specifications.

3.0 Site Planning and Preparation

3.1 Cell Site Survey Proper site planning and site preparation is required to assure the success of a OneBaseCell Extender System and to protect the investment. A site-walk must be done before installing the system. The following Site Survey information must be obtained prior to final design configuration of the system:

Cell Site Administrative Information: Cell site company, contact name/number, site number and address, site access

information Shipping address for equipment Expected installation date Duration of trial

Existing cell site equipment configuration: Air interface(s) (CDMA, GSM, etc.) BTS model(s) Frequency bands Number of antenna feed lines Antenna types (Vertical polarization, Horizontal polarization, etc.) Information on the Tower Mounted Amplifiers (TMAs) installed, including their

model number, their power handling specifications, number of sectors, breakdown of simplexed and duplexed lines, power input to MCPA, and existing alarm interfaces

DC power plant make, model, breaker types and ratings Block diagram showing RF cabling of existing equipment Dimensioned floor diagram showing equipment footprint and allocated space for

MCPA, floor type RF cable identification (color, number of stripes) for each sector

Mechanical and Installation information: Planned floor area for MCPA equipment, indoor versus outdoor HVAC Cable lengths and routing Specific physical size constraints Installation material list (jumpers, connectors, DC feeders, breakers, DC

distribution, alarm interfacing cable, mounting hardware) Battery back-up requirements

RF parameters for MCPA application:



Frequency band, block, number of carriers, power per carrier desired, transmit (Tx) diversity requirements, BTS interface specifications

Note: Local building and fire codes govern the manner in which most site preparation and installation tasks are performed. Andrew Corporation recommends consulting a local building inspector or a licensed engineer to assure that the site conforms to local building codes. 3.2 Restricted Access Installation Because of the complexity and working power of the OneBaseCell Extender System , it is strongly suggested that the system be installed only in areas which have restricted access, such as dedicated equipment rooms, equipment closets, environmental shelters, or similarly designated areas. Access should be controlled and limited to qualified personnel. 3.3 Floor Space The proper floor layout is determined from the required dimensions of the different frame configurations (See Chapter 2). The following materialsas a minimum listshould never be used as a floor covering because these materials could cause serious danger or system failure:

Combustible materials Industrial carpeting Materials which could generate electrostatic charges.

3.4 Lighting The OneBaseCell Extender System is designed to be installed and serviced under normal workroom lighting. During installation, room lighting must be bright enough to allow reading instructions and inspection of modules, but not so bright as to interfere with viewing the status LED indicators. The OneBaseCell Extender System should be oriented or else protected from direct sunlight on the front panels of the modules. 3.5 Fire Protection Andrew Corporation recommends that the OneBaseCell Extender system installation site be equipped with smoke detectors and an automatic fire extinguishing system. In addition, for the safety of site operators, a hand operated Halon, or CO2 fire extinguisher should be available.



3.6 Altitude When installing the OneBaseCell Extender System above 10,000 feet, decrease the maximum permitted operating temperature by 2 C per 1000 feet above 10,000 feet. 3.7 Maximum Operating Temperature The OneBaseCell Extender System requires unrestricted airflow around the entire frame. Therefore, the site must be ventilated or air-conditioned so that ambient air does not exceed 50 Celsius (122 F). 3.8 Air Quality The OneBaseCell Extender system should be installed in a location that is free of airborne dust and toxic or corrosive fumes. 3.9 Vibration and Noise The OneBaseCell Extender can function at moderate levels of vibration and ambient noise. However, the OneBaseCell Extender should not be installed in a location subject to mechanical shocks, or vibrations conducted from nearby mechanical equipment. The OneBaseCell Extender System generates fan noise below 60 dBa during operation, so no additional acoustic treatment of the site is needed. 3.10 Lightning Protection Andrew Corporation recommends that all power, RF, and signal lines that connect to the OneBaseCell Extender System be protected by approved lightning arresting system starting with a properly grounded chassis. This lightning arrestor must have a suitably rated ground cable running directly to ground. The Filter Modules do contain lightning protection. Lightning protection must comply with local Fire and Electrical Safety Codes for lightning protection required. 3.11 Electrical Grounding The OneBaseCell Extender System and entire equipment rack must be grounded with a properly engineered grounding system, including ground halo and ground rods.



3.12 Housing Clearance Space 3.12.1 Indoor Frame Only six (6) inches of clearance space is required behind the indoor frame for airflow to exhaust heated air. Rear access is required only during initial installation to connect the DC power supply. During operation, the indoor frame configuration requires clearance for unrestricted cooling air input into the front panel, plus a minimum of six inches behind the MCPA Booster System. No additional rear clearance is needed to accommodate routing of the RF input and output cables and the DC power cables because all connections are on the front of the system and the wires and cables are located to the sides of the frame and up during installation. In addition, the system frames are open design unlike standard 19 electronic equipment frames. The widest dimensions are the dimensions of the stacked subracks in the frame. In particular, the edges of the Input Trays are the widest point.

3.12.2 Outdoor Cabinet The outdoor cabinet requires 24 inches of clearance space for unrestricted cooling air input into the cabinet in flush baffled panel openings and for operator access into the cabinet. No additional rear clearance is needed to accommodate routing of the RF input, output and DC power cables, since all connections are on both sides and at the top of the OneBaseCell Extender System Cabinet. During installation the wires and cables are located to the sides inside the cabinet. Like the indoor system configurations, up to three (3) subracks can be mounted in a full-sized outdoor cabinet.



4.0 Installation

The OneBaseCell Extender System is shipped as individual packaged modules, subrack(s), frame(s) or cabinets and cabling It is strongly recommended to locate the OneBaseCell Extender System in as close proximity as possible to the existing RF equipment and/or antenna, so that existing cables will remain the same length and new cables be as short as possible and also so that ground wiring and DC return wiring can be connected to the same point.

SAFETY WARNING: Each empty Subrack and each MCPA module weigh approximately 35 pounds. When crated for shipping a OneBaseCell Extender System can weigh in excess of 1350 pounds and be unbalanced. To avoid injuries or damage, use care and obtain assistance before lifting the crate containing the OneBaseCell Extender System CAUTION: Do not attempt to handle a OneBaseCell Extender System subrack with MCPA modules installed without assistance CAUTION: When removing an MCPA module, support the module from the bottom as it is withdrawn to avoid damage to the fan housing. NOTE: Local building and fire codes govern the manner in which some site preparation and installation tasks are performed. Andrew Corporation recommends that local building inspectors or a licensed engineer is consulted to assure that the site installation conforms to local building codes

UNPACKING OF ANDREW CORPORATION EQUIPMENT MUST OCCUR AT ONLY THE CELL SITE AT WHICH THE EQUIPMENT IS TO BE INSTALLED. ANDREW CORPORATION EQUIPMENT SHOULD NEVER BE UNPACKED, UNCRATED, INSPECTED, OR ASSEMBLED AT ANY WAREHOUSE OR ANY LOCATION OTHER THAN THE FINAL CELL SITE LOCATION.

STEP 2: Remove the packing lists, installation kit, documentation CD, and other documents attached to the shipping container. STEP 3: Examine shipping documents to make certain that they agree with the purchase order. STEP 4: Access the Configuration Sheet from the CD and verify that the shipped hardware matches with the ordered configuration. STEP 5: Open the packages using the required safety equipment and tools. Do not damage any items or scratch the frame and module finishes. STEP 6: Verify that there is no damage to the system. If any damage, notify the carrier and Andrew Corporation immediately. STEP 7: Verify that the ESD protective wrapping is intact and surrounds the modules. Do not remove the ESD protective wrapping that surrounds the modules until actual installation.



STEP 8: Remove spacers, packing inserts, plastic bags, and the protective coverings from only the rear of the modules and not from the front panels. STEP 9: Remove all other shipping materials from the outside of the packages. Do not use knives or scissors for this task. STEP 10: Retain any necessary original packaging if items are to be returned. Contact Andrew Corporation Customer Service for detailed instructions. STEP 11: Dispose of the remaining packing materials.

4.3 Install the Frame Each OneBaseCell Extender System floor frame must be secured to the floor with 4 (four) suitable bolts after the footprint is positioned as planned. The requirements are for height, front, sides and rear clearance of each OneBaseCell Extender System must clear obstructions by six (6) inches for proper air flow.

4.4 Install the Subrack into the Frame Subracks are usually pre-installed in the outdoor cabinet or indoor frame before shipping to the cell site. However, there are occasions when subracks must be installed in the frame at the cell site. The following instructions are provided for those occasions. A Subrack mounts into the frame using the subrack mounting hardware (which includes enough 5/16 slotted hex head 12-24 thread forming, Tri-Lobe, long screws for the particular configuration installation). The type and number of Subracks (maximum of 3) in a frame is determined by the configuration. STEP 1: Determine the spacing and location of each subrack in the frame or cabinet before installing the first subrack. This spacing is required to allow room for the filter modules. There are hole locations on the frame or cabinet which must match up with the proper holes in the subrack for proper subrack mounting. STEP 2: Using a hydraulic lift or additional individuals, lift the subrack into the proper position in the frame. STEP 3: At the proper frame position, drive five (5) mounting screws (from the installation kit) into the mounting holes in the frame. As the screws are driven into the mounting holes, the screws will form threads in those holes. As many of the five (5) holes in the four (4) mounting flanges two on each side of the Subrack, into holes that will permit being threaded (some holes in the flanges will not line up with holes in the frame). STEP 4: Turn each screw and press each screw into the properly selected hole in the frame.



STEP 5: When the maximum number of screws for the configuration have been installed, the subracks are ready for modules and cabling. The OneBaseCell Extender System is labeled with the part and serial numbers, using standard EIA part identification, date code information, and serializing methods. It is also labeled with the appropriate FCC approvals where necessary. All subracks are shipped with all necessary wiring for the correct configuration. This consists of inter-module RF signal distribution, cabling and the RF Combiner Module, if equipped. The other RF cables are packed separately for the RFIMs, Filter Modules and RF Input Trays.

Figure 24: Subrack ready to be installed into the indoor frame.

4.5 Install the RFIM Modules In most cases the RFIM(s) are installed in the subracks at the factory. The following procedure is used if the RFIMs are NOT installed at the factory.

CAUTION: Use extreme care when plugging in RFIM module to prevent pins from being damaged.
