Ripwave Base Station I&C Guide Navini Networks, Inc. Chapter 2b 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.

Navini Networks, Inc. Ripwave Base Station I&C Guide Chapter 2b 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.

Navini Networks, Inc. Ripwave Base Station I&C Guide Chapter 2b 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.

As mentioned earlier, the model of GPS antenna used with the Ripwave Base Station is the VIC 100, as shown in Figure 27. Mount each GPS antenna module, run the cable through the pipe clamp mount. Connect the cable to the GPS antenna, then, weatherize the connection.
