SAFETY INFORMATION Personnel installing OpenSky rack-mounted components at a communication site should be aware of a number of potential hazards. These hazards may be associated with OpenSky electronic and Radio Frequency (RF) equipment, radio antennas used with these components, or with the environments in which components are housed. Keep in mind that when working in the field, hazards associated with equipment, antennas, or environmental conditions that are part of applications other than OpenSky radio may also present risks. Hazards you may encounter include the following: • RF emissions • Electrical shock • Lifting of heavy objects • Falling objects • Falls • Poor ergonomic design • Chemical exposure Working around the hazards listed above does not necessarily pose any outstanding risk to health or safety - however, knowledge of these possible hazards is vital to working safely.
MM102225V1, Rev. B 10 The safety guidelines and precautions presented in this manual do not replace M/A-COM's specific requirements. The primary responsibility for health and safety standards, practices and guides lines in a M/A-COM project lies with the Environmental, Health & Safety (EHS) department. All M/A-COM managers, supervisors, or subcontractors responsible for work associated with OpenSky equipment must be completely familiar with and prepared to comply with all applicable EHS guidelines and requirements. Although M/A-COM's policy requires that all contractors and visitors must be adequately trained prior to working on any M/A-COM project, this does not mean M/A-COM is responsible for conducting or providing this training. The following safety precautions must be observed during all phases of operation, service, and repair of this product. Failure to comply with these precautions or with specific warnings elsewhere in this manual violates safety standards of design, manufacture, and intended use of the product.

MM102225V1, Rev. B 13 2.0 SITE PREPARATION 2.1 INTRODUCTION This section provides instructions for preparing the site and other installation items, which must be completed prior to installing OpenSky Communication equipment. The areas covered include the following: Antenna System - This includes installation of the antenna tower, receive and transmit antennas, tower top amplifier and the installation of the transmission lines from the antenna to the tower top amplifier to the equipment shelter. Site Requirements - Information is provided concerning various factors, which may affect the physical location of the equipment facility. Facility Preparation - This section provides information for preparing the facility prior to installing the equipment. This information includes proposed equipment layout, environment, electrical power, equipment room grounding and telephone line installation. 2.2 ANTENNA SYSTEM This section covers installation of the antenna system, including RF cables from the antennas to the equipment room wall feedthrough. Antenna systems are generally installed by crews trained and equipped for working on antenna towers. As a result, this manual assumes the Antenna systems are installed by crews with the specialized equipment and skills required for working on towers and installing the antenna cables. However, it may be necessary for the system installer to provide information and directions to the crew installing the antenna system and to verify proper installation. 2.2.1 Antenna Mounting The antenna tower must allow antenna mounting that provides isolation of at least 25 dB between the TX and RX antennas. This is necessary to avoid interference in the trunked receivers caused by the trunked transmitters. An isolation of greater than 25 dB is easily obtained by placing one antenna directly above the other on the tower (minimum 10-foot separation). 2.2.2 Transmission Lines When installing the transmissions lines, refer to the diagrams contained in Antenna System Maintenance Manual LBI-38983. 2.2.2.1 Length The length of the main coaxial cable for each antenna is planned as a continuous run with no connectors or splices between the antenna and the equipment room. Each cable includes a 50-foot allowance for the distance from the bottom of the tower to the equipment room. Smaller diameter, more flexible coaxial cables are used at both ends of the main coaxial cable to facilitate installation.
MM102225V1, Rev. B 14 2.2.2.2 Minimum Bending Radius Always adhere to the minimum bending requirements provided by the manufacturer. For Andrew Products, the values are: CABLE SIZE BENDING RADIUS 1/4-inch 1/2-inch 7/8-inch 1-5/8-inch 1-inch (25 mm) 1.25-inch (32 mm) 10-inches (250 mm) 20-inches (510 mm) 2.2.2.3 Hoisting Grips Hoisting grips provide the means to attach a lifting mechanism to the coaxial cable without damaging the cable. Each hoisting grip is capable of safely lifting 200 feet of cable without causing damage. Therefore, one hoisting grip is required for every 200-foot section of cable. The grips may be left attached to the cable after the cable installation is completed. Some situations may require more hoisting grips, such as: • An installation to a tower which is on top of another structure. • Any installation where the length of cable that must be lifted is greater than the height of the tower. In these situations, additional hoisting grips should be ordered. WARNING Under NO conditions should RF connectors be used to attach a rope or cable. 2.2.2.4 Hangers and Adapters Coaxial cables on the tower should be secured at intervals of 3 feet (maximum). Securing 7/8-inch and 1 5/8-inch diameter coaxial cables is accomplished by using either hangers or hanger-adapter combinations. The hangers secure the cables to the tower structure by using prepunched holes or attachment adapters. When the tower structure is prepunched with 3/4-inch holes, snap-in hangers are used (preferred method). When the tower is prepunched with 3/8-inch holes, the hanger is secured by a 3/8-inch bolt. For towers without prepunched holes, the hangers are attached with adapters. The type of adapter depends on the type of tower structure. Adapters are available for either angle tower members or round tower members.
MM102225V1, Rev. B 15 Adapters for each antenna system are selected when ordering the system. If the coaxial cable must be attached to a structure that is not compatible with any of the above hangers or adapters, then additional materials or other special considerations may be required. To secure 1/4-inch or 1/2-inch vertical or horizontal coaxial cables of any size, use UV resistant, black nylon cable ties. 2.2.2.5 Weatherproofing A kit of weatherproof tape is provided to protect coaxial connectors from the outside elements. One roll of tape is sufficient to weatherproof four exposed outside connector joints (More than four are required with a Top Tower Antenna). 2.2.2.6 Antenna Grounding Grounding kits are installed to prevent the radio system from being damaged by lightning. A grounding point should be installed at the top end of each coaxial cable run on the tower. A second grounding point should be installed on each cable at the bottom of the tower and a third grounding point on the cable at the point where the cable enters the building, if the tower-to-building length is greater than 20 feet. For cable runs on the tower greater than 200 feet, additional grounding points should be installed at each 200-foot interval. Grounding points should be installed at the Tower Top Amplifier as well. 2.3 TOWER TOP AMPLIFIER The Tower Top Amplifier (TTA) should be installed near the receive antenna in order to improve the receive (inbound) channel performance. The amplifier should be mounted to the tower structure with corrosion resistant hardware and grounded to the tower structure with a #6 AWG solid or stranded copper conductor. All TTA ground connections, whether to tower frame (angular or circular) or a tower ground buss, should be made with corrosion resistant hardware. For the TTA a "drip loop" in the RF cable from the antenna is recommended. 2.4 SITE REQUIREMENTS This section provides information for preparing the facility prior to installing the equipment. This information includes proposed equipment layout, environment, electrical power and telephone line installation. 2.4.1 Floor Plan Direct access to the area (for antenna cables and personnel) between the tower and the equipment room is necessary. Standard floor plans for the equipment cabinets are side-by-side cabinets. Lengths of interconnect cables supplied are based on these standard floor plans. If a floor plan other than a standard floor plan is used, longer interconnect cables may be required. 2.4.2 Operating Environment The equipment room where the base station equipment is installed must meet the environmental conditions listed in the Station Specifications section of this manual.
MM102225V1, Rev. B 16 Although the temperature requirements for individual pieces of trunked equipment may be broader, when several units are assembled together in a cabinet more heat is generated. Because of this condition, the ambient room temperature outside the cabinet must be lowered to ensure the temperature inside the cabinet does not exceed the limits for the equipment. 2.4.3 Electrical Power Normally, OpenSky equipment is powered by –48 VDC. If the OpenSky cabinet is equipped with an AC power supply and an AC power cord, a 20-amp circuit breaker for each AC supply is recommended. Receptacles must be installed within reach of the power cord(s). This can be on the wall behind the cabinets, in the floor under the cabinets, or in the cabinet top cable ducts. Each station power supply power cord is about 3 meters (9.8 feet) long, starting at the back of each power supply (two or three different heights) within the rear of each station cabinet. Each cord plugs into an AC Outlet which has a cord length of about 3 meters (9.8 feet) long. When required, the AC power supplies are omitted from the station cabinet. In this case, DC power must be supplied to the base stations from an external -48 VDC power source through a separate 30-amp circuit breaker for each base station. Additional equipment may be required if other types of power sources are used, or if the power source is not within reach of the individual AC power cords. 2.4.4 Equipment Room Grounding Ensure all equipment and facilities meet the requirements for grounding and lightning protection. Installation Manual AE/LZT 123 4618/1 - Standard For Site Grounding and Protection provides instructions for proper grounding of sites and radio equipment. These procedures should be observed in order to protect the equipment and service personnel from lightning and other sources of electrical surges. This manual is included as part of system documentation. 2.5 ANTENNA SYSTEM QUALITY AUDIT Before installation of the antenna begins fill out APPENDIX J- INSTALLER PROFILE DATA SHEET. After the Antenna System is installed it should be inspected before the installers leave. A checklist of tasks performed on the antenna system is provided in APPENDIX K - ANTENNA SYSTEM INSTALLATION CHECKLIST. Be sure to complete this visual inspection before the installers leave, so any obvious errors can be corrected. 1. Using field glasses (if necessary) view the Antenna System from various positions on the ground. Using copies of the Antenna System Installation Checklist found in APPENDIX K, fill out a checklist for each antenna as you go through the following inspection procedure. This will provide a record of the inspection, and of some antenna information for future reference. 2. Record the make of antenna. 3. Record the type of antenna (omni or directional).
MM102225V1, Rev. B 17 4. Record the design gain of the antenna. 5. If the antenna is directional, record the bearing of the main lobe, using the magnetic declination for True North. If it is Omni, write "Omni" in the data entry line. 6. Record the height of the antenna above ground. 7. Confirm that cable-hoisting grips were installed as required to prevent damage to the coaxial cable. Hoisting grips should have been installed at the antenna end of the cable plus one for each 200 feet of cable length. 8. Confirm the cable is secured to the tower at intervals, which do not exceed 3 feet. 9. Confirm the cable is grounded at the top of the tower. 10. Confirm the cable is grounded at the point where it leaves the tower. 11. Confirm the cable is grounded at the point where it enters the building. 12. Confirm the coaxial cable run looks OK. The cable must be tight (nothing to flap in the breeze), have no dings or kinks, be one continuous run (no connectors or splices), and not exceeding the minimum bending radius on any bend. 13. Confirm the cable weather tight feedthrough is properly installed where the cable enters the building. 14. Confirm the coaxial connectors have been properly weather sealed. 15. Confirm the cable entrance to the building has been properly weather sealed.
MM102225V1, Rev. B 18 3.0 BASE STATION INSTALLATION The following sections present the steps required for installation of populated OpenSky base station equipment racks at a communications site. To a certain extent, installations must be planned site-by-site, because of the wide variety of installation conditions and configurations. Installers will encounter many types of equipment enclosures and tower site equipment configurations. The Site Deployment Order (SDO) should include an accurate site layout map, information to designate rack locations, and other necessary installation information. 3.1 BEFORE INSTALLATION OCCURS Before the antenna installation date, collect the information from the Site Deployment Order specific to site access. Site-specific information includes the following: • Permission to access the site • Directions to the site • Keys and lock combinations to access the site and equipment shelter, or points of contact to obtain them • A drawing or description of each site showing where the equipment is to be installed inside the enclosure • Information about work practices needed to work safely at the site The installation procedure below assumes that the installation team has secured permission to access the communications site and has obtained the necessary keys or lock combinations. CAUTION Keep working environment clean! Control dust, dirt, and shavings for safety, and to protect equipment. Be sure to follow installation procedures carefully! 3.2 BASICS Generally, the OpenSky base station fits into two or more equipment racks. Each rack is nominally seven feet high and twenty-four inches wide. The populated racks must be installed inside a weatherproof enclosure near the base of a communications tower. If an OE-100 Outdoor Enclosure is used, the OpenSky equipment is mounted to the mounting rails provided within the enclosure (Refer to OE-100 Outdoor Enclosure Maintenance Manual MM102226V1). The Base Station installation procedure addresses the following: • Installing the equipment racks after they have been transported to the communications site and moved into the equipment shelter • Making inter-rack cabling connections
MM102225V1, Rev. B 19 • Connecting the power supply and site subsystems external to the OpenSky equipment racks 3.3 SECURING EQUIPMENT RACKS TO THE FLOOR Move the racks into the designated positions and prepare to bolt them to the floor. In rare cases, bolting to the floor may be prohibited. In those cases, bolt the racks to each other for stability. Procedure: 1. Using a template, mark bolt locations for each equipment rack to be installed. 2. Drill pilot holes (Drill any required pilot holes to the specified depth of 1-1/2"). 3. Drill 1/2" diameter holes for wood and concrete floors. 4. Move racks into position over bolt marks. In general, racks are placed side-by-side in numerical order, with Rack #1 leftmost when viewed from the front. 5. If necessary, level the racks. The racks should be, at a minimum, approximately level. If necessary, shim the racks so they are level by eye (use of an actual level is better). 6. Align the front of the racks. 7. Bolt equipment racks to the floor. Follow the procedure below corresponding to the type of floor in the shelter. In general, equipment installers will encounter four types of floor: concrete, concrete covered with linoleum, wood, and raised floors. The procedure for each type is as follows: • For concrete floors, use 1/2" drop-in expanding anchors with an insulating nylon washer under the fastener head to anchor the racks (see Figure 3-1: Bolt Assembly Hardware and Figure 3-2: Nylon Washer and Bolt Assembly). 1. Drill pilot holes for the anchors using the appropriate-sized carbide-tipped drill bit. The pilot holes must not exceed 1-1/2" in depth. 2. Insert the anchors into the pilot holes. 3. Place insulating phenolic strip(s)2 and under the cabinets/racks before bolting them in place. 4. Place the cabinet/rack over the holes. 5. Assembly the bolts, fender washers and nylon washers. 6. Insert the bolt and washer assemblies into the pilot holes. 7. Tighten the bolts until firmly set (see Figure 3-3: Concrete Floor Mounting and Figure 3-4: Bolt Assembly Used to Bolt Rack to Concrete Floor). CAUTION Be careful not to over tighten bolts to avoid breaking the phenolic bushings. 2 Phenolic strips are only required if the floor is pure concrete. Concrete floors covered with linoleum do not require phenolic strips.

MM102225V1, Rev. B 21 Figure 3-4: Bolt Assembly Used to Bolt Rack to Concrete Floor • For wood floors, use a lag bolt with an insulating nylon washer under the head to bolt the racks to the floor. Insulating phenolic strips under the racks are not required. No pilot hole is needed on wood floors. • For raised floors, the rack attachment procedure is quite different. The first and last racks in the row are bolted to the sub-floor as shown below. The remaining racks are bolted to the end racks, to each other, or both. Insulating phenolic strips must be placed under each rack (see Figure 3-5: Raised Floor Rack Attachment).

NOTE In most installations, this connection goes to microwave equipment. 3.4.7 Site Clean Up Before leaving, remove any debris, such as wire clippings, metal shavings, dust mounds, etc. from the site. 3.5 COMPLETING THE INSTALLATION Once the OpenSky equipment has been installed, perform field testing as detailed in Section 4.0 SITE TEST PROCEDURES to verify operation according to specifications of installed equipment racks with externally connected subsystems such as antennas. Procedures: 1. Perform testing to verify correct operation and performance of the installed equipment racks, following the procedures specified in Section 4.0 SITE TEST PROCEDURES. 2. Set HPA transmission power level, following the procedure specified in Section 7.06.7 -TX POWER CALIBRATION (MANDATORY). 3. If problems occur during installation, describe them and detail how they were resolved. If the installation could not be completed, describe the obstacles and clearly explain what was done and what remains to be done.
MM102225V1, Rev. B 33 4.0 SITE TEST PROCEDURES 4.1 PURPOSE AND SCOPE This section describes post installation tests required for compliance testing of the M/A-COM Wireless Systems OpenSky Digital Base Station. This section defines and details the test plan and methodology for each test. Objective: This test confirms a base site receive channel is not corrupted by site specific noise or interference. Site installation and site gain optimization should be completed before this test is performed. The NIMCAS site optimization program provides an expected difference between terminated and antenna connected quieting tests. Measured results should be within 2 dB of this value. This section covers tests that perform two functions: • Verify that all contractual requirements as detailed in the system Requirements Traceability Verification Matrix, (RTVM), are met. These tests are identified as mandatory and are linked to the relevant section for the RTVM. • Ensure that the site, as installed, is operating at optimum performance. These tests are not mandatory but clearly have impact on some of those that are. To ensure that the system is installed and configured correctly, the following procedures must be performed. In addition, several tests are performed to validate the RF performance of the station and to ensure compliance with the station FCC license. This section is therefore divided into the following areas: • Verification Testing • Equipment Configuration • Compliance Testing • Performance Testing • Operational Testing • Network Connectivity • Final Operating Capability • Appendices: Supplemental information on equipment configuration and control access. ⇒ Base Site Configuration Procedure should also be consulted for configuration questions (see APPENDIX F - TYPICAL BASE STATION CONFIGURATION). ⇒ Installed Site Cavity Tuning Procedure should also be consulted for Filter Tuning (see APPENDIX H - VERIFICATION TESTING – TRANSMIT FILTER TUNING).
MM102225V1, Rev. B 34 4.2 OVERVIEW OF OPENSKY BASE SITE EQUIPMENT An OpenSky base station consists of a variety of products and includes radio transmitting and receiving equipment, RF distribution equipment and network communications system interface equipment. OpenSky is a digital system and has some significant differences in terms of fixed network connectivity to that commonly seen with conventional analog systems. In particular, base station controllers (BSCs) communicate via an access server and are connected back to a central office or dispatch center via digital circuits. OpenSky base station equipment is available in five primary RF configurations. This document covers Types 1, 2, 3, and 4 listed below. Type 5 is covered separately. 1. Primary site with separate transmit and receive antennas: Referred to as a Tower Top Site. 2. Primary site with a single antenna for transmit and receive: Referred to as a Duplexed Site. 3. Outdoor Enclosure with separate transmit and receive antenna. 4. Outdoor Enclosure with a single antenna for transmit and receive. 5. Low profile site providing coverage fill: Referred to as a Cell Site. 4.3 TEST METHODOLOGY Equipment configuration and testing must be performed in accordance with the instruction given in this document. Tests must also be conducted in the order given in this document as adjustments made during certain procedures may affect the results of other tests. Testing an installed base site comprises performing standard forward and reverse channel tests to ensure correct operation of the entire installation. Testing also verifies physical and application layer connectivity to the Regional Operations Center serving the site under test via a communications link. Required specifications are verified using one of the following methods: 1. Inspection: An observation or examination of an item against the applicable documentation to confirm compliance with the requirements. 2. Analysis: Interpretation, interpolation, or extrapolation of analytical or empirical data under defined conditions of reasoning to show theoretical compliance with stated requirements. 3. Demonstration: Verification of an operational or functional capability by one or more performances before qualified witnesses, as designated by the customer. Instrumentation or data recording beyond that provided indigenously by the elements to be verified shall generally not be required. 4. Objective Test: Performance of a functional operation under specific conditions involving the use of instrumentation, special test software, and/or special test equipment to generate, acquire, and/or record data. This method may include an analysis of test data.
MM102225V1, Rev. B 35 4.4 PREPARATION To prepare for the start of testing, it is important that all test equipment be powered up now and allowed to thermally stabilize. Begin by powering up the Communications Test Set HP 8920. Record the specifics of each of the system components. Before testing the complete system, verify that the system is cabled correctly. The tower-mounted receive amplifier will not power up until it senses that the indoor control panel has been connected via the RF feed cable and the multi-conductor control cable. The initial sections of this procedure describe how to check for correct installation, particularly those areas that were disturbed as part of the shipping process. 4.5 RECORDING TEST RESULTS The main body of this document provides space for the recording of all test results and equipment configuration parameters. These must be supplemented where indicated by equipment configuration hardcopy printouts taken for each RF channel being tested. 4.6 BASE SITE BLOCK DIAGRAM Figure 4-1: 3-Channel Base Station with Tower Top Amplifier Block Diagram, shows the Block Diagram for a three-channel site installation.
