Introduction 1
The RIM 802D Radio Modem set a new standard for radio
modem performance in key areas, such as 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 Radio Modem operates on DataTAC wide-area
wireless data networks in the 800 MHz range. DataTAC
networks are deployed by Motient in the United States and by
Bell Mobility in Canada.
The RIM 802D Radio Modem is designed to integrate easily
into a computing device. Potential applications include:
• Laptop computers • Vehicle tracking
• Point-of-sale devices • Monitoring and telemetry
• Ruggedized terminals • Vending machines
• Handheld computers • Utility meters
•Parkingmeters • Billboards
• Dispatching •Securityalarmpanels

Introduction
RIM 802D Radio Modem Integrator Guide

Radio performance
The RIM 802D Radio Modem offers high performance on
DataTAC networks.
Receiver sensitivity
The RIM 802D Radio Modem has a receiver sensitivity of
–118 decibel milliwatts (dBm) using the MDC over-the-air
protocol, and –111 dBm using RD-LAP, at a 0.05 packet error
rate (BER). The 5% BER is an industry-standard error rate used
to define sensitivity.
Receiver sensitivity is a measure of how well the radio modem
can receive and decode data from a network base station. This
figure is important when a device is 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.
Noise immunity
RIM radio modems are not desensitized 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:
• easier integration
• longer battery life
• increased reliability
• improved RF performance
• more coverage from each base station
• no need for special RF shielding

RIM 802D Radio Modem Integrator Guide

Powerful and efficient transmitter
The RIM 802D Radio Modem is designed to supply a full 2.0
watts to the antenna.
RIM radio modems provide reliable, efficient transmission
across the entire operating voltage range of 4.1 to 4.75 volts.
Batteries can be used even when they are almost depleted,
which maximizes the radio coverage area throughout the life of
the battery.
Low power requirements
If you are planning to integrate RIM 802D Radio Modem into a
handheld or portable device, battery life is a critical issue
because customers insist on long-lasting devices without heavy
battery packs. The RIM 802D Radio Modem provides superior
power consumption to ensure efficiency and to maximize
battery life.
• Transmitting data: 1.7 A (at 4.5 V) when transmitting
2.0 W.
The transmitter is rarely turned on; it consumes power
only when the radio mode is sending data, which takes 21
to 1100 ms, depending on the amount of data transmitted.
• Receiving data: 61 mA (at 4.5 V)
The receiver is usually turned off, but it periodically turns
on to listen to the base station and determine whether any
packets are waiting to be received. The receiver duty cycle
varies depending on the over-the-air protocol used (5% for
RD-LAP and 10% for MDC).
• Standby power: less than 0.2 mA (at 4.5 V)
Standby power occurs when no radio activity has taken
place for at least 10 seconds. The radio and base station are
closely synchronized to ensure that a communication
attempt is not missed when the radio is in standby mode.

Introduction
RIM 802D Radio Modem Integrator Guide
14
Battery life is not a concern for some applications, such as
in-vehicle applications that draw power from the vehicle
battery. In this case, it is possible to put the radio in an express
operating mode, in which the receiver is on all the time. This
mode results in higher power consumption, but packet receive
latency is minimized.
Small size
Using a single-board design, the RIM 802D Radio Modem is
very thin, and smaller than a business card. It measures 1.65 by
2.66 inches (42.0 by 67.5 mm). This small size allows the radio
modem to meet tight space requirements within most
applications. Its single-board design is more reliable than
multi-board designs, particularly in high-vibration
environments (such as vehicles) or in devices that can be
dropped (such as handheld computers).
DataTAC network technology
DataTAC wireless network technology was developed by
Motorola for IBM. DataTAC has become an international data
communication standard. It is a secure, reliable, wireless
packet-switching network specifically designed for wide-area
wireless data communications.
DataTAC provides reliable, 2-way digital data transmission.
The network provides error detection and correction to ensure
the integrity of the data being sent and received, and includes
transmission acknowledgment.
The networks have a hierarchical structure that enables
messages to be routed from sender to receiver along the most
direct path possible. Each radio cell is served by an intelligent
base station. Because intelligence is distributed throughout the
network, data is only forwarded to the lowest network node
that is common to the sender and the receiver. As a result, one
base station is able to handle all traffic in its coverage area.

Introduction
RIM 802D Radio Modem Integrator Guide
15
The network constantly monitors the location of mobile users.
As a mobile device moves from one area of coverage to
another, base stations track its signals, sending updated mobile
location and status information to the network. If the network
is unavailable at any point in transmission, the message is held
until network service is restored. If the mobile receiver moves
outside the coverage area, the base station stores the data until
coverage is re-established, then forwards it to the mobile
device. This process prevents data loss, and increases the
reliability of transmission.
DataTAC is optimized for data communication. It uses a
packet-switching technique to provide the greatest flexibility in
data transmission. By contrast, conventional cellular phone
systems use a circuit-switched network, in which a physical
connection is created between the sending and receiving nodes.
This connection must be maintained throughout the duration
of the transmission. With circuit-switched systems, the setup
time for establishing a connection involves significant
overhead and airtime cost, especially when only a small
amount of data needs to be transferred.
Network data packets include information about the origin,
destination, size, type, and sequence of data to be sent. This
information enables packets to be transmitted individually, in
any order, as traffic permits. Internal to the network, individual
packets can travel along different routes, in any order, without
interfering with other packets sent over the same frequency by
different users. At the receiving end, all packets are accounted
for, and reassembled into the original message.
Setup time is eliminated and network connection is
instantaneous. Packet-switching uses channel capacity
efficiently, typically allowing 10 to 50 times more users over a
radio channel than a circuit-switched network.
