Introduction
The Boomer II OEM Modem Module is a radio packet modem,
intended for use on Motorola DataTAC 4000 SFR and DataTAC 5000
MFR data communication networks.
It is primarily designed to be integrated into customer equipment as an
OEM module, for use with a host running wireless applications or as
the RF communications enabler device for telemetry products. There
are two versions available,
 800MHz version (A band) and
 900MHz version (B band)
Messages from the end user are sent from the host device through the
serial interface, and are transmitted by the modem when it is in
network contact. Messages to the end user are received and
acknowledged by the modem, then passed to the user’s host.
Within an area of coverage, the modem performs auto-roaming (auto-
scanning, channel selection, and registration on a new channel). The
modem operates in either battery save or non-battery save modes, as
instructed by the network and overridden by the host computer. The
modem determines which RF protocol to use, based on the attributes
specified by the configured channel list, and dynamic channel
information from the network.
The modem interfaces to the host controller by using the data interface
port. The protocol supported over this link is the Native Control
Language (NCL).
Although the modem has embedded software, it has no built in
application software. All application software must be separately
installed and run from the host to which the modem is connected. A
Software Development Kit (SDK) is available and described later in
this manual to assist this process.

Applications
Suitable devices in which the Boomer II OEM Modem can be used
include the following applications:
Meter Reading
The modem can be used to read billing information from intelligent
electrical meters and basic disc meters. Data is transmitted wirelessly
through a radio network to billing computers.
Point of Sale
The modem can perform handshaking and complete verification of all
data transmitted through the wireless network whilst providing
convenient operator mobility such as open air events or conferences.
Vending Machines
Vending machines can also utilise radio data technology. Many
machines already transmit usage and refill requirements to company
head offices via standard telephone lines. Radio modems allow vending
machines to be placed in areas with poor access to telecommunications
infrastructure, providing a cost-effective alternative to installing new
telephone lines. On refilling, only the required refills will be
despatched to the required sites maximising truck carrying capacity and
consequently efficiency.
Alarm Detection
Conventional telephone wire connections are slow to dial out and can
burn before the emergency call can be placed. Laws in many states and
countries require businesses to have an on-line dial out fire alarm
system. The Boomer II OEM Modem offers a real solution to this
problem.
Parking, Buses and Ticketing
Ticketing machines are being be converted to cashless operation. The
Boomer II OEM Modem is the best alternative to facilitate the
introduction of this cashless technology.

The Integrator’s Task
This section provides background information and points out the
objectives and tasks of reaching the goal of a successful
implementation.
Areas of Focus Benefits
Serial Port
Pass-Through Capability
 Enables modem diagnostics
and software upgrades
without the need to
disassemble the host device
or terminal.
Understanding RF Design  Provides the required
network coverage.
 Sets end-user performance
criteria.
 Reduces risk of costly
redesigns.
Software & Hardware  Provides reliable operation
through a state-of-the-art
functional interface.
 Helps ensure longer service
life and fewer field returns.
Because wireless data communication technologies are usually
described using a unique variety of jargon, buzzwords, and technical
details, it is sometimes hard to know where to start. You may also have
difficulty evaluating this technical information when you find it.
As an OEM integrator, you must accurately choose where and how a
wireless technology will facilitate communication for your application.
You will also have to evaluate which technical considerations will give
your product an edge over the competition.
To successfully integrate the Boomer II OEM wireless modem into the
host platform, you must perform the following tasks:
 Plan the product and create the design
 Develop and validate the hardware
 Develop supporting applications software
 Test and approve the product
As you review these tasks, allow sufficient time for such required
activities as the regulatory approval process. Identify critical path
activities up front.

Integrator’s Task ____________________________________________ Boomer II User Manual & Integrator’s Guide
Wavenet Technology 16 BM210012WT27
Plan the Product and Create the Design
To plan the product and create the design, perform the following steps:
 Develop a usage model.
 Develop a message model.
 Define a service strategy.
 Investigate and obtain regulatory approval.
Develop a Usage Model
The usage model answers the question, “How will the end product be
used (portable or mobile; 8 hours, 7 days a week; and so on)?”
Perhaps the most important enabler of success is a clear determination
of how the final product is to be used. This steers the development
process, because all design considerations drive toward meeting the
needs of the final user. For example, design issues related to a mobile
device, such as alternator noise and vibration, are completely different
from considerations required for a fixed-point telemetry application
powered by a solar panel. Defining what is and what is not important to
the end user helps to make the critical engineering trade-off decisions
that are inevitable in every product design.
Develop a Message Model
The message model defines how many messages are sent/received and
how often. To create the message model, determine how much and
how often data will be sent in each of the uplink (terminal to network)
and downlink (network to terminal) directions.
Answer the question, “Is there a requirement for the terminal to be on
and able to receive 8 hours a day, or does the user turn the unit on only
when making a query to the host system?” The answer has a direct
bearing on the battery size and capacity requirement for powering the
device. The amount of data sent and received is relevant in calculating
the cost of airtime and deciding on which type of network connection
to use. In short, the message model is required source data for making
many engineering design decisions, especially in calculating such
values as sleep time versus wake time and in determining battery
capacity requirements.
For additional information, refer to section “Message Traffic Model”
on page 47. The typical approach to creating the model is to define the
peak and average network throughput requirements based on input
from the user. Wavenet Technology is able to provide current
consumption figures for each of the various modes of operation
(receive and transmit, for example) and explain the functionality of the
network Power Save protocol.
The network throughput of the host device depends on many factors in
addition to the raw throughput of the radio channel. For example, in
addition to the overhead involved in forward error correction and

Boomer II User Manual & Integrator’s Guide ____________________________________________ Integrator’s Task
BM210012WT27 17 Wavenet Technology
support for packet headers, the number of active users on a shared RF
channel can directly affect network throughput.
Define a Service Strategy
The service strategy determines whether the integrated modem is the
cause of a user’s problem and sets a policy for keeping the end user
operational during repair. The service strategy must consider all
potential service situations and evaluate them in light of the usage
model.
To ensure that a final product can be efficiently serviced, you must
design for service-ability early in the development process. At a
minimum, you must develop a functional service strategy that contains
a well-considered procedure for performing unit-level screening. The
test must primarily determine whether a fault lies with the modem or
with the product. The test must also screen for network problems and
human error.
Wavenet provides an evaluation board (a standalone test jig) and
various software test utilities. The evaluation board provides a
mounting platform and electrical interface to the modem. Testing is
performed much more efficiently while the modem is still integrated
within the host device or terminal, whether for a factory end-of-line test
or while at the user’s site.
For your product to allow integrated testing of the modem, you are
required to provide modem pass-through mode and utilise Wavenet
RSUSER software. See “End User Problem Resolution” on page 70.
Without pass-through, the modem must be mounted on the evaluation
board for diagnostics and troubleshooting. Pass-through mode also
allows for modem software upgrades.
A thoroughly developed OEM serviceability plan typically includes a
needs assessment for developing software utilities that can assist in
identifying communication problems between the host device and the
modem and between the modem and the RF network.
These utilities must be able to send commands to the modem, evaluate
the modem responses, perform network connectivity testing, and verify
data communication with the network.
The utilities can be developed using NCL. This link-layer protocol set
provides the capability to monitor and evaluate the modem’s operating
condition and all communications to and from the network host.
NCL 1.2 uses a command-response functional model. First, the
network host asks for modem status and status of network connectivity.
The modem then responds with its status and the state of network
connection management.
Such a software utility is essential for field service engineers and shop
technicians to diagnose problems with the product and to troubleshoot
a problem to a failed assembly or mismanaged communication link.

Integrator’s Task ____________________________________________ Boomer II User Manual & Integrator’s Guide
Wavenet Technology 18 BM210012WT27
Diagnostic Capabilities
To provide modem diagnostics, there are three LEDs on the modem
itself. When the unit is first powered up it goes through its own self test
and the status is reflected in the visual status of the LEDs.
Customer Problem Isolation
When application-visible problems are discovered in the field, you
must isolate the source of the problem. Is it the network, wireless
modem, or the host product that is not working as expected? Often it
can be a user’s misunderstanding of how to use the product.
Regardless, remote troubleshooting is essential to reducing the number
of returned products and lowering service costs, particularly if the host
must be disassembled for removal of the modem.
Wavenet recommends that your product application (both at the
terminal and host ends) incorporate sufficient problem diagnostic
software to determine the cause of the problem remotely. Often, the
best approach is to incorporate progressively deeper loop back tests to
determine the point at which the communication link fails.
As stated elsewhere, you need to make this remote diagnostic
functionality be part of your standard software load.
End User Support
You have two choices in dealing with an integrated modem that needs
to be swapped out and returned for service:
 Decommission the modem and re-use the LLI
 Replace the modem
If you decommission the modem Id (the LLI) from the defective unit
and transfer it to a replacement unit, the user and the network operator
are unaffected. This can only be done by an authorized Wavenet
service centre with the appropriate permissions and authority. If you
simply swap the defective unit with a replacement, the user must notify
the network operator.
Investigate and Obtain Regulatory Approval
Most countries where the final product will be sold currently require
approval from the local government regulatory body. It is your
responsibility to investigate and obtain the proper regulatory approval
and certification for each country in which the product is sold.
Regulatory issues are discussed in more detail in “Regulatory
Requirements” on page 23. In addition, see “Regulatory Compliance”
on page 69.

Boomer II User Manual & Integrator’s Guide ____________________________________________ Integrator’s Task
BM210012WT27 19 Wavenet Technology
Develop and Validate the Hardware
To develop and validate the hardware, perform the following steps:
 Design the hardware platform
 Consider power supply options
 Select the source antenna
 Set up a development test environment
Design the Hardware Platform
Integrating a wireless modem into a hardware design requires many
steps. Here again, the usage and message models are necessary to
calculate issues such as battery size, heat dissipation, isolation from
EMI, and physical mounting of the unit to ensure proper grounding.
Hardware design is your responsibility. Wavenet can provide
recommendations where applicable and may also assist with
verification of EMI-caused desense once the modem is integrated into
the host.
Consider Power Supply Options
Power supply requirements vary according to the usage and message
models. Beyond accounting for the current drain of the modem in its
various operating modes, consider ripple and noise on the power lines,
and the ability to supply sufficient instantaneous current to allow
proper operation of the transmitter. Also, ensure that the power supply
can accommodate the highest power consumption under transmit
conditions and that the voltage does not fall below the minimum levels
at the modem terminals. (Remember voltage drops can occur in the
interconnectivity wiring and this must be kept as short as possible.)
Together, these requirements define the type and size of power supply
to use with the modem. These issues are discussed in more detail in the
sections “Power Management” on page 45 and “Batteries” on page 51.
Important: Avoid use of switching power supplies. They can easily
cause RF noise that desenses the modem.
Select the Source Antenna
The ERP (Effective Radiated Power) generated by the antenna must
meet the requirements of the various network operators. Consider these
network requirements when you select an antenna system. See
“Connecting & Positioning the Antenna” on page 40.
Set Up a Development Test Environment
A number of development test aids are available to assist in hardware
and applications development. Wavenet can provide both the modem
hardware and an evaluation board. The evaluation board is a specially
developed circuit board with test points and jumper switches. The

evaluation board allows for maximum flexibility in accessing and
controlling connections into and out of the modem. Wavenet also
provides various software utilities that can help in performing
development tests. See “Testing” on page 67.
Supplementing the test environment, the network operator sometimes
provides a live development network, one separate from the production
network on which you can develop and test your application.
Develop Supporting Applications Software
To develop supporting applications software, perform the following
steps:
 Select a communications model
 Develop end-to-end applications software
Select a Communications Model
Select a communications model. Most vertical market applications use
fleet host (SCR) connections to a single host, whereas horizontal
applications typically use a gateway to allow connection to the Internet
or other external networks. See “Air Interface Protocols” on page 27.
Develop End-to-End Applications Software
In addition to coding the product-specific features for your application,
you are urged to incorporate RF-specific reporting and monitoring
features, such as received signal strength (RSSI), channel quality, and
in-range/out-of-range conditions. Many applications track the number
of packets sent and received and the various events and status
indicators available from the modem. The Boomer II modem uses a
packetised serial interface (Native Control Language 1.2) to allow the
application to simultaneously monitor RF-related information and
application-specific data.
Test and Approve the Product
To test and approve the product, perform the following steps:
 Perform EMI and desense testing
 Set up a final test environment
 Install and field test the product
Perform EMI and Desense Testing
Proper modem operation requires that you minimize EMI
(electromagnetic interference) radiated from your product’s platform.
Excess noise significantly reduces the wireless modem’s ability to
receive, making the network less likely to be heard.
