Navini Networks, Inc. Base Station I&C Guide Chapter 2a Part #40-00047-02 Rev F v1.0 (TTA) 41 October 23, 2003 Chapter 2: Installation Pre-installation As was shown in Figure 4, prior to installing the equipment a number of planning and acquisition activities take place. The installation itself takes only about 2 days. The I&C crew may or may not be involved with all the pre-installation activities. Of these, they are most likely to be involved in the Site Candidate Evaluation, the gathering of data for the Interference Analysis, and the Antenna Power & Cable Selection step of the process. Project Plan A Project Plan is a document that lays out the work to be done, the objectives of the project, the schedule, resources required, and so forth. If Navini is performing the I&C activities, a Project Manager is assigned. The Project Manager prepares the Project Plan and shares it with the Navini and customer teams. An example of a written Statement of Work (SOW), Responsibility Assignment Matrix (RAM), and Work Breakdown Structure (WBS) for installation and commissioning are provided in Appendices A, B, and C. These types of documents may be used in negotiating work between companies and contractor services. Coverage Prediction Map Early in the planning of deployment of Ripwave Base Station equipment, an RF Engineer will go through the process of studying the RF environment of the candidate sites that the customer has identified. Readings are taken and analyzed at each site in order to predict what range of coverage can be expected from installing a Base Station at the site. Coverage predictions account for both Base Station performance and Marketing objectives with the service itself. The customer accomplishes the latter as part of the decisions concerning site selection. Ripwave Base Station I&C Guide Navini Networks, Inc. Chapter 2a 42 Part #40-00047-02 Rev E v1.0 (TTA) October 23, 2003 Site Candidate Evaluation Often Technicians will be very comfortable with either the networking side or the wireless side of the system, but not usually both. To evaluate a potential install site, a form helps ensure all aspects of the site have been considered. Information about the site is recorded on the form. Since each site is unique, the form helps to ensure nothing is taken for granted or assumed about the installation site for the Ripwave equipment. A copy of this form may be found in Appendix D. It includes places to capture the logistics of the site, tower or rooftop mount possibilities, GPS coordinates, type of antenna to be installed, whether or not an outdoor enclosure is provided, power availability, distance between connection points, ventilation, a place for drawings from every angle, etc. It is from this information that the site will be designed, then installed to plan. Interference Analysis As part of deploying a Ripwave Base Station, the Field Service Engineer must collect critical information from the site. The data is provided to the RF Engineering personnel, who can then evaluate the Radio Frequency (RF) conditions. The RF Engineer analyzes the data for existing interference from other sources, and takes that into account when creating the coverage prediction map. The RF Engineer, in turn, supplies to the Field Service Engineer at the site valuable data parameters and configuration information unique to each system and each site. In addition to coverage, though, the interference analysis also helps to predict the quality of service, the power requirements to get above the noise floor, and other expectations regarding the site. This study helps Navini and the customer decide which type of system (frequency) and antenna (panel or omni) will provide the best results. To collect the data the on-site Technician or Field Engineer performs an Interference Sweep Procedure (Appendix E) and supplies that data to the RF Engineer(s). Refer to Appendix F for instructions on using the sweep tool. Site Selected & Designed After evaluating the potential sites and the coverage prediction, the customer must select the specific site where the Base Station is to be deployed. The site must be carefully blueprinted to prepare for equipment ordering and installation. Navini can supply specifications and drawings to help the customer design the site. Refer to Appendices G, H, I, J, and K for BTS Specifications, RFS Data Sheets, BTS Outdoor Enclosures Manufacturers, Rectifier/Battery Backup Manufacturers, and a sample Base Station drawing. Check all regulatory standards (refer to Chapter 1, Page 8 “Regulatory Information”) prior to installation. Navini Networks, Inc. Ripwave Base Station I&C Guide Chapter 2a Part #40-00047-02 Rev F v1.0 (1.20) 43 October 9, 2003 Network Architecture Plan The IP Networking community involved in the project, both from Navini and the customer, often work together to analyze and plan how the Ripwave system will be integrated into the customer’s network. Of course, they are looking for efficient operation of the system and seamless integration. They have to plan the traffic routing, IP addressing, protocol compatibility, and so forth. Antenna Power & Cable Selection The size and type of cable used to install the Base Station affect power loss and calibration range for the transmitter and receiver. It is at this point in the process that the specific cable manufacturer, type of cable, and cable size must be determined. A complete procedure and tool are explained in Appendix L. Refer, also, to Chapter 1, Page 8 “Regulatory Information” for FCC warning regarding RF, and UL and NEC/CEC information regarding cable length and connectors. All BTS and RF shelf Coax and Digital cables between the Digital and RF Shelves are 60 inches in length. Physical distance between Digital and RF Shelves will always be less than the cable length. Bill of Materials The customer has to generate the Bill of Materials (BoM) - the actual equipment order to be manufactured and shipped to the installation sit…

Navini Networks, Inc. Ripwave Base Station I&C Guide Chapter 2b Part #40-00047-03 Rev F v1.0 (TTA) 55 October 23, 2003 Install the BTS Check all regulatory standards (refer to Chapter 1, Page 8 “Regulatory Information”) prior to installation. Install Mounting Rack or Enclosure The BTS mounting rack (Figure 22) or enclosure is to be installed in compliance with applicable portions of the National Electrical Code (NEC), articles 800 and 810. You will need to adhere to local installation standards, as well as Navini Networks standards and procedures. Refer to Appendix I for manufacturers of outdoor BTS enclosures. Figure 22: BTS Mounting Racks Combo Chassis Split Chassis TTA Chassis Combo Chassis Split Chassis TTA Chassis Ripwave Base Station I&C Guide Navini Networks, Inc. Chapter 2b 56 Part #40-00047-03 Rev F v1.0 (TTA) October 23, 2003 Install Chassis There are three types of BTS chassis: Combo, Split and TTA (Figure 23). Prior to Ripwave Release 1.19 (2.4 GHz systems), only the Combo Chassis was used, but with the licensed bands (2.3, 2.5, and 2.6 GHz systems) it is allowed to transmit at higher levels of power, which required better air circulation. This resulted in the introduction of the Split Chassis. The recently introduced Tower Top Antenna (TTA) chassis, consists only of a digital shelf because the PAs are incorporated into the base of the RFS. Notice that the TTA digital shelf includes 8 new additional cards called RF Controllers or RFC. CAUTION! - Please contact Navini Technical support before attempting to exchange cards between chassis of different type and frequency to verify compatibility. Figure 23: BTS Chassis Combo Chassis Split Chassis TTA Chassis RF/PA Shelf Digital Shelf (Panel separates RF and Digital Shelves) (PAs are in the RFS) Combo Chassis Split Chassis TTA Chassis RF/PA Shelf Digital Shelf (Panel separates RF and Digital Shelves) (PAs are in the RFS) Navini Networks, Inc. Ripwave Base Station I&C Guide Chapter 2b Part #40-00047-03 Rev F v1.0 (TTA) 57 October 23, 2003 Connect Input Power Next, connect the power supply to the BTS card cage (Figure 24). The gauge of the wire is determined by the length of the run and by NEC/CEC standards (refer to Chapter 1, Page 8 “Regulatory Information”). Use a 60-amp circuit breaker when running the line. Terminate both of the input power wires and the ground wire with a ¼- inch terminal lug. Assuming a +24 VDC power supply, connect the +24 VDC input power connections and the +24 VDC return wires to the BTS card cage. WARNING! Ensure that the power is off before connecting the input power wires to the BTS input terminals. If the input power is 120 VAC, plug the two power-supply input cables into 120 VAC outlets, and turn on the circuit breaker on the power supply. If the input power is 24 VDC, check for +24 VDC across the input terminals of the BTS card cage. If +24 VDC is not present across the input terminals, check all input power wiring for proper connections. Also, check the power supply for proper operation and the fuses for continuity. When finished, turn off the power supply.

Ripwave Base Station I&C Guide Chapter 2b Part #40-00047-03 Rev F v1.0 (TTA) 59 October 23, 2003 Connect BTS to Ground Connections All connections need to be checked before power is applied to the system. At a minimum, perform the following: ??Ensure continuity across all ground connections. ??Ensure an open connection from the power supply output (positive input to the BTS card cage) to frame ground. Check all regulatory standards (Chapter 1, Page 8 “Regulatory Information”) related to power and grounding. All power and ground conductors must be mechanically supported to avoid strain of the wires and connection points. Figure 26: Preparing Power and Grounding Connector Tips Connect Chassis Alarms The chassis contains two connectors that are used to send alarm indications to the BTS when the BTS is housed in an outdoor enclosure. One of the connectors, labeled “CABINET ALARM”, is used to trigger alarm conditions that occur within the external chassis. The second connector, labeled “BBU”, is used to process alarms from a battery backup unit. Refer to Appendix P for instructions on connecting the alarms.
