Important Notice
Because of the nature of wireless communications, transmission and reception of
data can never be guaranteed. Data may be delayed, corrupted (i.e., have errors) or
be totally lost. Although significant delays or losses of data are rare when wireless
devices such as the AirLink Communications modem are used in a normal manner
with a well-constructed network, the AirLink Communications modem should not be
used in situations where failure to transmit or receive data could result in damage of
any kind to the user or any other party, including but not limited to personal injury,
death, or loss of property. AirLink Communications, Inc., accepts no responsibility
for damages of any kind resulting from delays or errors in data transmitted or
received using the AirLink Communications modem, or for failure of the AirLink
Communications modem to transmit or receive such data.
Safety and Hazards
Do not operate the AirLink Communications modem in areas where blasting is in
progress, where explosive atmospheres may be present, near medical equipment,
near life support equipment, or any equipment which may be susceptible to any form
of radio interference. In such areas, the AirLink Communications modem MUST BE
POWERED OFF. The AirLink Communications modem can transmit signals that
could interfere with this equipment. Do not operate the AirLink Communications
modem in any aircraft, whether the aircraft is on the ground or in flight. In aircraft,
the AirLink Communications modem MUST BE POWERED OFF. When operating,
the AirLink Communications modem can transmit signals that could interfere with
various onboard systems. The driver or operator of any vehicle should not operate
the AirLink Communications modem while in control of a vehicle. Doing so will
detract from the driver or operator's control and operation of that vehicle. In some
states and provinces, operating such communications devices while in control of a
vehicle is an offence.
The antenna connection is intended for indoor use only. It is not intended to be
connected to an outdoor antenna.

WARNING
The antenna(s) used for this transmitter must be installed to provide a
separation distance of at least 20 cm from all persons and must not be co-
located or operating in conjunction with any other antenna or transmitter.
1Introduction
The AirLink CDMA modem is designed to operate in CDMA networks. Two services
are available in the CDMA networks: 1xRTT, a packet switched connection, and IS-
95B, a circuit switched connection.
CDMA IS-95B
The AirLink CDMA modem is capable of making IS-95 connections. The modem first
connects to the CDMA network and the network then connects to the call to either
the Public System Telephone Network (PSTN), or to the Internet using QNC. These
calls use an Interworking Function (IWF) to bridge the CDMA network to the PSTN:
Internet
CDMA
Network
IWF
PSTN
For Internet connections, the Interworking function can use a special feature called
QNC (Quick Net Connect). The IWF provides a link to the Internet without going
through the PSTN. Establishing a standard point-to-point call requires the Airlink
CDMA to configure a modem at the IWF. It is the IWF modem that actually connects
to the PSTN and dials the number. Call progress is not directly available to the local
modem, although some information can be exchanged. When the IWF has completed
the handshake with the remote modem, the local modem is advised and the
connection is complete.

CDMA2000 1X
The AirLink CDMA modem provides data capability into the packet service offered
with CDMA2000 1X (1xRTT) technology. CDMA2000 1X offers higher speed data
operations than are available with IS-96 service. IS-95 is limited to 14.4 kbps. 1X
service uses a fundamental channel at 9600 bps and can add supplemental channels
when needed to boost speed to as high as 153.6 kbps on the downlink (network to
modem) and 76.8 kbps on the uplink (modem to network).
1.1 Product Overview
The AirLink Redwing CDMA is a rugged, full duplex 1xRTT CDMA modem that
provides wireless transport capabilities for fixed and mobile applications. CDMA is
an efficient and secure wireless technology that works well for fixed or mobile
applications.
The Redwing CDMA is ideally suited for fixed and mobile Industrial or Commercial
Applications, including Telemetry, SCADA, Public Safety, Mobile Dispatch, Field
Service, Financial Transaction Processing, and Security applications. The CDMA
Redwing enables virtually any PC, PDA, or networking device (router, server, etc) to
access the CDMA/1xRTT data network. The Redwing CDMA can also be used in
installations with many different types of Remote Terminal Units (RTUs),
Programmable Logic Controllers (PLC’s) or other computers that perform metering
and monitoring functions in the oil, gas, water, and transportation industries. The
Redwing CDMA can be a low-cost replacement for many existing landline, private
radio and circuit-switched cellular installations.
