Ripwave Base Station I&C Guide
I&C Process Flowchart
To put the I&C activities in the context of overall system deployment, Figure 2 provides a ‘flow’
of the key activities that are performed prior to and during the installation and commissioning of
the Ripwave Base Station. Post-I&C, the system that has been installed and commissioned goes
through Acceptance Testing against the customer’s objectives for that site. Once customer signoff on the site is achieved, the customer becomes fully responsible for operating the system.
Different job holders may perform various portions of these activities and not necessarily all of
the activities. In fact, Marketing and Engineering personnel typically handle the earlier tasks,
while installation may be a stand-alone function. Commissioning may or may not be handled by
the same people who designed or installed the site. Regardless of who does them, these key
activities have to be accomplished for successful deployment:
•
•
•
•
Site Engineering
Installation
Commissioning
Acceptance Testing and sign-off
Prior to installation, Navini and the customer formulate a Project Plan and Responsibility
Assignment Matrix (RAM) to clarify who will do what to complete the I&C activities. If
requested by the customer, Navini may provide personnel, procedures, forms, and/or tools
required to install and commission the Base Station equipment. They may also provide special
commissioning software programs, computers, and any other special test equipment required.
As part of the I&C duties, all testing results are recorded and kept for the customer to review and
approve. These test results include the cable sweeps, the BTS Calibration Verification, RF
System Tests, Drive Study, Line-of-Sight (LOS) FTP tests, and Non-Line-of-Sight (NLOS) FTP
test results. The I&C Supervisor provides site tracking and weekly status reports. All of these
tasks can be negotiated with the customer.
If Navini Networks is hired by a customer to provide Installation & Commissioning Services,
involvement and some actual deliverables are still required by the customer. For example, the
customer will need to review or perhaps even explain their Site Design Specifications, approve
Logistics Plans, provide shipping information, approve the Network Architecture Plan, etc.
As part of a successful hand-off from Navini to the customer, it is usually necessary for Navini to
provide some product training to customer personnel who will support the Base Station operation
on-going. Customers may opt to take on a Train-the-Trainer program, in which case Navini
certifies the customer’s instructors who then provide staff training thereafter.

Base Station Components
Base Transceiver Station (BTS)
The BTS consists of the RF Power Amplifiers (PA’s), 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 two types of chassis: Combo and Split. 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 3).
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.

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 Customer Premise Equipment (CPE)
using a digital beamforming transmission technique. The RFS may be either a panel antenna or
an omni antenna (Figure 4).
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 BTS’s. 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). For downtilt, the omni must be situated as it comes from the factory. A
panel’s downtilt can be adjusted at the site. The higher up the antenna is placed, the more
downtilt it typically required.

Global Positioning System (GPS)
One or two Global Positioning System (GPS) antennas are used with each Base Station. A GPS
antenna works with a constellation of satellites that orbit the earth, and it provides the ability to
pinpoint geographical locations. The two types of GPS antennas that may be ordered with a
Ripwave Base Station are the VIC 100 and the Motorola Timing 2000 (Figure 5).

General Specifications
Input Power
The BTS requires +21 to 28 VDC power supply rated at 60 amps. Installers are referred to
industry standards for power supply installations.
Humidity
The operating environment of the BTS must control relative humidity to 5% to 95% RH, noncondensing.
Heat Dissipation
The combo BTS chassis, under normal operating conditions, will dissipate a maximum of 1000
Watts or 3415 BTU’s. The split chassis will dissipate a maximum of 1500 watts.
Airflow
Fresh air intake for the BTS chassis is along the lower front vertical panel. Exhaust is out of the
upper rear of the chassis. The I&C crew must ensure there are no obstacles to airflow present in
these areas. Exhaust air from other equipment should not mix with the BTS fresh air intake.
Accessibility
The BTS is intended for installation and use only in a restricted access location.

Ripwave Base Station I&C Guide
Chapter 2: Installation
Pre-installation
As was shown in Figure 2, prior to installation a number of planning activities take place. The
installation itself takes only about 2 days. The I&C crew usually is not involved with all the preinstallation activities. Of these, they are likely to be most involved in the Site Candidate
Evaluation.
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.
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 as well as Marketing objectives with the service itself. The
customer accomplishes the latter as part of the decisions concerning site selection.
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 is used to ensure
all aspects of the site have been considered. Information 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 B. 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.

Ripwave Base Station I&C Guide
Navini Networks, Inc.
Interference Analysis
The RF Engineer(s) also analyzes existing interference from other sources, and takes that into
account when creating the coverage prediction map. 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 will help Navini and
the customer decide which type of system (frequency) and antenna (panel or omni) will provide
the best results.
Network Architecture Plan
The IP Networking community involved in the project, both from Navini and the customer, 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.
Bill of Materials
Someone has to generate the Bill of Materials (BoM) - the actual equipment order to be
manufactured and shipped to the installation site. Navini can provide part numbers and ordering
information, as well as recommendations and other details that will assist customers in the
correct placement of orders. There is a sample Bill of Materials in Appendix O.
Backhaul Connections
The Backhaul connections for the Ripwave Base Station consist of up to two (2) Ethernet cable
connections with RJ-45 connectors for each BTS installed, OR, up to eight (8) T1 connections
with RJ-48 connectors for each BTS. The quantity of each connection will depend on the site
requirements. These connections need to be made available before installation begins.
Power Requirements for the Base Station
The input power source will be determined during the site survey. The DC power source needs to
be an independent hard-wired circuit of 21VDC to 28VDC with a 50-amp breaker for the Combo
Chassis and a 70-amp breaker for the Split Chassis. The power plant return bus must be
connected to an earth ground connection similar to the Base Station chassis. Insulated #6 AWG
cable is recommended. The combo chassis system generates up to 1000 Watts, and the split
chassis system generates up to 1500 Watts maximum; however, 1353 Watts is typical.

Ground Requirements for the Base Station
The Base Station requires an earth ground connection. This ground should exhibit a maximum of
five ohms across true ground.
NOTE: The installation procedures, which begin next, follow the same order as shown in
the I&C Flowchart in Figure 2.
An example of a Base Station drawing for a particular site is provided in Appendix P.
An example of a written Statement of Work (SOW) and Responsibility Assignment Matrix
(RAM) for installation and commissioning are provided in Appendices Q and R. This type of
document may be used in negotiating work between companies and contractor services.

Install Power & Grounding
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.
Mount the data/power cable surge protectors (Figure 7) with the label ‘lines’ toward
the RFS and the label ‘BTS’ toward the BTS.
Step 2.
Apply a thin coat of anti-oxidant joint compound to both sides of the system ground
buss bar to ensure proper connection between it and the surge protectors.
Figure 7: Data/Power Cable Surge Protector
To install the eight (8) antenna and one (1) cal cable surge protectors (Figure 8), and the one (1)
or two (2) Global Positioning System (GPS) surge protectors (Figure 9) in the system ground
buss bar, follow the steps below.
1. Install the rubber gasket into the groove in the surge protector.
2. Install the surge protector in the system ground buss bar with the surge side toward the
antenna and the protected side toward the BTS.
3. Install the star washer and nut on the top of the surge protector. Torque the nut to 140-150
inch-pounds.
4. When finished, the mounted surge protectors in the buss bar will appear as in Figure 10.

Cable Preparation
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. Leave enough extra
length for the service loop below the RFS and for connection to the surge protectors.
•
Cut eight (8) pieces of cable for the jumper cables to connect the surge protectors on the
system ground buss bar to the eight (8) RF input connectors on the back of the BTS.
Leave enough extra cable length for service.
•
Cut one (1) piece of cable for the jumper cable to connect the surge protector on the
system ground buss bar to the CAL connector on the back of the BTS. Leave enough
extra cable length for service.
•
Cut a piece of LMR 400 cable to connect each of the GPS antennas to the surge
protectors on the system ground buss bar. Leave enough extra cable length for service.
The maximum length of the LMR 400 cable for the GPS antenna is 100 feet.
•
Cut a piece of LMR 400 cable to connect the surge protectors on the system ground buss
bar to each GPS connector on the back of the BTS. Leave enough extra cable length for
service. If there is more than one BTS co-located in the installation, two GPS antennas
can serve all BTS’s in the installation.
•
The cable from the GPS antenna (after it goes through the surge protector) is connected
to the antenna input of the GPS distribution amplifier (Figure 12). The output ports of the
GPS distribution amplifier are connected to the GPS inputs of the BTS. The GPS
distribution amplifier is powered by the GPS antenna input. The drawing in Figure 13
depicts the placement of the shared GPS resources among three BTS’s.

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 K. For reference, Appendix L also provides a
list of vendors who can make cables.
Sweep Individual 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 C, 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.
