DRAFT FCC Compliance Statement (USA)
FCC Class B Part 15
This device complies with Part 15 of FCC Rules. Operation is subject to
the following two conditions:
1. This device may not cause harmful interference, and
2. This device must accept any interference received, including
interference that may cause undesired operation.
Warning
Changes or modifications to this unit not expressly approved by the
party responsible for compliance could void the user’s authority to
operate this equipment.
This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses
and can radiate radio frequency energy and, if not installed and used in
accordance with the manufacture’s instructions, may cause harmful
interference to radio communications.
There is no guarantee, however, that interference will not occur in a
particular installation. If this equipment does cause harmful interference
to radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
x Re-orient or relocate the receiving antenna.
x Increase the separation between the equipment and receiver.
x Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
x Consult the dealer or an experienced radio/TV technician for
help.

DRAFT Industry Canada Certification
This device complies with Industry Canada RSS 119, under certification
number xxxxx.
IC Class B compliance
This device complies with the Class B limits for radio noise emissions as set
out in the interference-causing equipment standard entitled “Digital
Apparatus,” ICES-003 of Industry Canada.

1. Introduction
With the introduction of the RIM 802D, Research In Motion (RIM) has set a
new standard for radio modem performance. The RIM 802D is unrivaled in the
key areas of receiver sensitivity, output efficiency, noise immunity, and power
consumption. Its small size and weight make it suitable for virtually any
wireless data application, including handheld devices and mobile terminals.
The RIM 802D is designed for use with DataTAC wide-area wireless data
networks operating in the 800 MHz range, such as the American Mobile
ARDIS network and the Bell Mobility ARDIS network.
RIM radio modems are specifically designed to integrate easily into a
computing device. Potential applications include:
x Laptop computers x Vehicle tracking and location
x Point of sale devices x Monitoring and telemetry
x Ruggedized terminals x Vending machines
x Handheld PC’s x Utility meters
x Parking meters x Billboards
x Dispatching x Security alarm panels
Radio performance
The RIM 802D offers the highest performance of any radio modem for
DataTAC wireless data networks:

2 Introduction – Radio performance
Integrator’s Guide – RIM 802D OEM Radio Modem DRAFT VERSION
Receiver sensitivity
Receiver sensitivity is a measure of how well a radio modem can “hear” a
network base station. This figure is important when a device will be used in
areas where signal strength is weak, such as inside buildings and in locations
that are not close to a base station. A radio modem with good receiver
sensitivity can be used in more places than a radio modem with poor sensitivity.
The RIM 802D has a receiver sensitivity of –118 dBm (MDC) and –111dBm
(RD-Lap) at 0.01 BER. This means that the radio can interpret received data
from a very weak 0.0025 picowatt signal with a 1% bit error rate. Although 1%
may seem like a high error rate, the sophisticated over-the-air DataTAC
protocol corrects these errors before the data is passed to the application,
ensuring error-free communication. This capability is already built into the
radio’s firmware, and does not require any additional software development.
Noise immunity
The RIM 802D is not de-sensitized by the electromagnetic interference (EMI)
or “noise” that is generated by the electronics of the terminal into which it is
integrated. As a result, no special shielding is required between the radio and
your device.
Noise immunity offers several key benefits, including:
x easier integration x improved RF performance
x longer battery life x more coverage from each base station
x increased reliability x no need for special RF shielding
Low power requirements
If you are planning to integrate the RIM 802D into a handheld or portable
device, battery life is a critical issue: your customers will insist on long lasting
devices without heavy battery packs. The RIM 802D sets a new power
consumption standard for DataTAC radio modems. This ensures efficiency and
maximizes battery life.
