Navini Networks, Inc. Ripwave Base Station I&C Guide 21 Chapter 1: Overview Ripwave Description A Ripwave system has three main components: the Base Station, the Modems, and the Element Management System (EMS). The Base Station performs the Modem registration and call processing, and provides the interface between the backhaul network and the EMS. It is made up of the Base Transceiver Station (BTS) and the Radio Frequency Subsystem (RFS) (Figures 1, 2 & 3). This manual provides the guidelines and instructions for installing and commissioning (I&C) the Base Station. Figure 1 shows the system with both Secondary (built-in) and Primary (optional) Lightning Protection. Lightning Protection helps to protect the RFS, the BTS, and the RF lines against “tower lightning” events occurring at the Base Station. The customer must exercise judgment when balancing risk against cost to decide whether to install the primary protection kit at an extra cost or to rely on the secondary protection only. NOTE: Navini does not warranty equipment against lightning strikes. In addition to tower lightning events occurring at the base station, lightning events that occur miles away from the BTS could generate intense electrical currents traveling over the power and/or backhaul lines and into the BTS equipment, damaging it. For this reason, Navini recommends adding surge protection devices at the power and backhaul demarcation points.

Rectifier Surge Protection Device Surge Protection Device Navini Networks, Inc. Ripwave Base Station I&C Guide 22 Figure 2: TTA Configuration with Secondary Surge Protection Only CAUTION! Although Secondary surge protection is built into the TTA that ships from the factory, Navini recommends that the Primary surge protection kit be purchased and installed, in particular if the equipment is installed in an area where electrical storms are common. Surge protection devices should be added in front of the rectifier. Lightning striking miles away from the BTS may cause an intense electric current traveling on the power and/or backhaul lines and into the BTS, damaging the equipment.

Navini Networks, Inc. Ripwave Base Station I&C Guide 35 Base Station Components Base Transceiver Station (BTS) The BTS consists of the RF Power Amplifiers (PAs), the digital circuit cards, the backplane, and the mechanical enclosure or housing. It performs the signal processing and RF transmission for the system. There are three types of chassis: Combo, Split, and Tower Top Amplifier (TTA). The Combo Chassis is used primarily with 2.4 GHz systems. The Split Chasses is used for all other (2.3, 2.5, 2.6 GHz) systems (Figure 5). The TTA is the latest chassis design, and is available at this time for 2.4 and 3.5 GHz systems. The chassis is compartmentalized into two sections - the RF shelf and the Digital shelf. The BTS connects to the network using a 10/100 Base-T Ethernet connection or up to 8 T1 interfaces. Up to three BTS assemblies can be installed per system, depending on the configuration. The BTS specifications are provided in Appendix C . Figure 5: BTS Chassis TTA ChassisTTA ChassisTTA ChassisTTA Chassis Navini Networks, Inc. Ripwave Base Station I&C Guide 36 Radio Frequency Subsystem (RFS) The Radio Frequency Subsystem (RFS) is mounted on a transmission tower or building rooftop. It transmits and receives data to and from the Ripwave Modem using a digital beam forming transmission technique. The RFS may be either a panel antenna or an omni antenna (Figure 6). The RFS data sheets are provided in Appendix E . An RFS panel transmits in a directional mode, covering a transmit angle of 120 degrees. The antenna can be used as a single mode antenna, or it can be used in a group of two or three sectored antennas, covering 240 and 360 degrees respectively. Each panel requires a BTS to operate. For example, in a tri-sectored cell with 3 panels, you would need 3 BTSs. The omni antenna provides omni-directional coverage of 360 degrees. An RFS panel or omni contains eight (8) antenna elements, cavity filters, and, optionally, low noise amplifiers (LNA). In the TTA configurations, the PAs also are located in the RFS (antenna) by the LNAs and cavity filters. Navini Networks, Inc. Ripwave Base Station I&C Guide 37 Global Positioning System (GPS) One Global Positioning System (GPS) antenna is used with each Base Station to provide a timing signal for synchronizaton. A second GPS antenna can be provided for redundancy. The Ripwave Base Station uses the VIC 100 GPS Antenna (Figure 7). Figure7: VIC 100 GPS Antenna CAUTION! GPS synchronization is essential for the BTSs in a network not to interfere with one another Mounting Racks & Enclosures The BTS can be installed indoors or outdoors in industry standard 19- or 23-inch racks. Rack adapters are needed to mount the equipment in a standard 23-inch rack. For outdoor BTSs, the customer can supply any standard enclosure from a multitude of vendors. Appendix E offers suggestions for outdoor BTS enclosures. Figure 8 shows 3 BTSs installed indoors. Accessibility Ripwave BTS equipment is required to be installed in a restricted access location, in accordance with NEC/CEC standards. Only authorized personnel should have access to this equipment.

Navini Networks, Inc. Ripwave Base Station I&C Guide 51 Bundle Cables for the TTA Configuration The bundle cables are manufactured by CommScope in 5 m increments. On the end that attaches to the antenna, the RG-6 or RG-11 bundle cables come with a weatherized “boot” and nine the N-type Male connectors in place. At the other end, the connectors can be N-type, if the cables in the will be connected to surge protectors in a buss bar (Primary Protection); or QMA, if the cables are to be connected directly to the BTS (Secondary Protection only). In the first case, N- type to QMA jumper cables are needed to connect the surge protectors in the buss bar to the BTS. You can optionally cut the bundle cable to the proper length, attach the connectors, and install the boot on site by yourself. Use a torch to heat-shrink the boot, being careful not to burn it. Figure 18 Bundle Cable, Weatherized “Boot” and End Connectors Cal Port (BTS back plane) RFCs (BTS front) N-type QMA Cal Port (BTS back plane) RFCs (BTS front) N-type QMA Navini Networks, Inc. Ripwave Base Station I&C Guide 52 Install Connectors on Cables Install connectors on both ends of each cable. For LMR 600 cables, install EZ-600 N-type male connectors. For LMR 400 cables, install EZ-400 N-type male connectors. Steps for installing both types of connectors can be found in Appendix J . For reference, Appendix H also provides a list of vendors who can make cables. The Cal and RF cables in the Combo and Split Chassis configuration have N-type male connectors at both ends. The Bundle Cable used with the TTA configuration has N-type male connectors at the antenna end, but the connectors used at the other end depend on the degree of lightning protection desired. Is only the built-in protection is used, the connectors at the BTS end are QMA male, but if the Ancillary surge protectors are used, the connectors at the BTS end of this cable are N-type male.

Ripwave Base Station I&C Guide 53 Sweep RF Cables Sweep each individual cable, the RFS (8) and CAL main feeder and jumper cables, to check for line loss. Follow the instructions for sweeping the cables provided in Appendix K entering the results in the RFS System Test Form. Check continuity of the data/power cable. When finished, cover the cable connectors for protection until they are connected to the RFS or GPS. Connectorize & Run Cables Connect all of the RF cables to the surge protectors in the system ground buss bar. An example of a buss bar connection is shown in Figure 14. Ensure that the proper cable is connected to the proper surge protector. Connect the power/data cable to its surge protector. Also connect all the jumper cables to the surge protectors that will attach to the BTS. Do not connect these cables to the BTS at this time. Torque all the cable connectors to the surge protectors on the system ground buss bar to 20-24 inch-pounds. Figure 20: Buss Bar Connections Route all of the cables – RFS (8), CAL, DATA/POWER and GPS (1 or 2) - between the system ground buss bar and the RFS, and GPS mounting sites. If running the cables up a tower, use a hoisting grip to lift the cables. GPS 1 GPS2 RF 1-4RF 5-8 CAL GPS 1 GPS2 RF 1-4RF 5-8 CAL Navini Networks, Inc. Ripwave Base Station I&C Guide 54 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 E for manufacturers of outdoor BTS enclosures. Figure 22: BTS Mounting Racks TTA ChassisTTA ChassisTTA ChassisTTA Chassis Navini Networks, Inc. Ripwave Base Station I&C Guide 55 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 Converters or RFC. CAUTION! - Please contact Navini Technical support before attempting to exchange cards between chassis of different type and frequency to verify compatibility. CAUTION! – In the TTA configurations, the RFCs output a +24 VDC current, which is carried to the RFS through the RF Cables. This DC current may damage test equipment connected directly to the RFC cards or to the end of the RF cables at the RFS. When connecting test equipment to the output of the RFC card, an external DC block may be required. Most signal generators and spectrum analyzers cannot handle DC voltage on the I/O ports. Please, read the caution stickers on the equipment and provide a DC block if the equipment cannot handle over "0"V DC. Figure 23: BTS Chassis TTA ChassisTTA ChassisTTA ChassisTTA Chassis Navini Networks, Inc. Ripwave Base Station I&C Guide 56 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!…
