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

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.

Procedural Documents & Forms
You will refer to other Ripwave documents, procedures, and forms in the process of installing
and commissioning the Base Station. The product documentation is provided on the Ripwave
Standard Documentation CD (Table 1). As well, the EMS manuals can be viewed on-line
through the EMS Server and Client applications.

A number of other forms are used in the installation and commissioning process. This I&C
Guide references those throughout, and provides copies in the appendices.
High-level I&C Process
To put the I&C activities in the context of overall system deployment, Figure 4 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. You
may find this flowchart can be used as a helpful checklist during the process.
23
Navini Networks, Inc. Ripwave Base Station I&C Guide
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 Selection, Design, and Preparation
• Physical Installation
• Commissioning, with 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.
