Preface

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 Sierra Wireless modem are used in a normal manner with a wellconstructed network, the Sierra Wireless 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.

Limitation of Liability

The information in this manual is subject to change without notice and does not represent a commitment on the part of AirLink Communications, Inc. AIRLINK COMMUNICATIONS, INC. SPECIFICALLY DISCLAIMS LIABILITY FOR ANY AND ALL DIRECT, INDIRECT, SPECIAL, GENERAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES INCLUDING, BUT NOT LIMITED TO, LOSS OF PROFITS OR REVENUE OR ANTICIPATED PROFITS OR REVENUE ARISING OUT OF THE USE OR INABILITY TO USE ANY AIRLINK COMMUNICATIONS, INC. PRODUCT, EVEN IF AIRLINK COMMUNICATIONS, INC. HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES OR THEY ARE FORESEEABLE OR FOR CLAIMS BY ANY THIRD PARTY.

WARNING: To satisfy compliance with FCC RF exposure guidelines:

All persons must be at least 20 cm from the antenna when the

transmitter is operating to meet FCC RF exposure requirements. This module is limited to operate with an antenna having a gain NOT exceeding 2 dBi.

1 Introduction

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 IS95B, 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 call types use an Interworking Function (IWF) to bridge the CDMA network to the PSTN.

AirLink Communications, Inc. Page 1 December 11, 2002

Redwing CDMA User Guide Version 1.0

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).

2 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.

Mapping for CDMA2000 Standards (TIA/EIA/TSB2000)

A thermistor inside the modem (monitored by the modem CPU firmware) causes flow control to be activated should the internal temperature reach 75ºC (167ºF) as measured at the radio. Flow control is released when the temperature falls below 75. Should the temperature of the radio reach 80ºC (176ºF), the modem terminates the connection in order to protect components and avoid drifting outside radio specifications.

3 Network Connection Options

The AirLink CDMA Redwing is capable of offering multiple network connection options. This section will illustrate the different network options that are available.

3.1 Internet (TCP/IP) Connections via 1xRTT

When using the Redwing CDMA, remote access to is done via a PPP (TCP/IP) connection to the CDMA network. The CDMA carrier actually provides Internet connectivity, and, therefore, it becomes the ISP for that session. Applications such as web browsing, email, FTP, etc should work as they would normally.

3.2 Circuit-Switched CDMA Connections

The Redwing CDMA provides traditional Circuit-Switched ‘dial-up’ communications. Where you would normally use a landline modem or analog cellular dial-up device, the Redwing CDMA can be a drop-in replacement. The CDMA carrier actually provides basic connectivity to the Public Switched Telephone Network (PSTN), so all that is needed is a CDMA activation (phone number) and connection of the serial cable. For connection to Windows computers, follow the setup profile for a Hayes Compatible or Standard 33600 baud modem. No special drivers or setup is required.
