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 sign-
off 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 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.

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 G.

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 6). The RFS data sheets are provided in Appendix H.
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.

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
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 I offers
suggestions for outdoor BTS enclosures. Figure 8 shows 3 BTSs installed indoors.
