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 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.

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

If the customer’s EMS Server is not available until after installation begins, the crew can typically use a laptop to perform initial configuration. The FTP Server, however, must be in place in order to commission the Base Station and test its operation.

System Ground Buss Bar & Surge Protectors The Base Station system ground buss bar and data/power cable surge protectors are mounted on the wall adjacent to the BTS rack or enclosure. They should be mounted per accepted telecom standards and procedures. Step 1.

Navini Networks, Inc. Ripwave Base Station I&C Guide Chapter 2a Antenna Ground Buss Bar You should install the Antenna Ground Buss Bar on the mounting structure per accepted telecom standards and procedures (Figure 13). The location is decided on during the site survey and should be close to the RFS. Two or more buss bars may be installed per system.

Ripwave Base Station I&C Guide Navini Networks, Inc. Chapter 2a Install Cables All cable connections in the Combo and Split-Chassis configurations are made using standard RF coaxial cable. The Navini Networks minimum for cable connections from the GPS to the BTS is LMR 400, 3/8-inch coaxial cable. Other types of cable that are comparable may be used. These were determined under “Antenna Power & Cable Selection” (Appendix L) activities cited earlier.

Navini Networks, Inc. Ripwave Base Station I&C Guide Chapter 2a Cut Cables for the Combo and Split Chassis Configurations The cable run is determined during the site survey. Note that the length of the cables may need to be slightly different, depending on the position of the buss bar relative to the BTS. ?? Cut nine (9) pieces of cable for the main feeder cables to connect the nine RFS connectors to the surge protectors on the system ground buss bar.

Ripwave Base Station I&C Guide Navini Networks, Inc. Chapter 2a 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 N. For reference, Appendix L also provides a list of vendors who can make cables.

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