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 colocated or operating in conjunction with any other antenna or transmitter.

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 calls use an Interworking Function (IWF) to bridge the CDMA network to the PSTN:

Internet

CDMA

Network

IWF

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.

2 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.

2.1 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.

2.2 Circuit-Switched CDMA Connections

Where there is carrier support for circuit-switched connectivity, the Redwing CDMA is capable of providing 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.

Practical Applications

Host Modem

The Redwing CDMA can be used as a modem connected to a host PC (or other device) and provide dial-up connectivity to the Public Switched Telephone Network (PSTN). Using the Hayes Compatible ‘ATD+Phone Number’ dialing sequence, the modem can dial any landline telephone modem. The diagram below shows how the application may be used.

Destinations

PSTN

Remote Modem

The Redwing CDMA can be used as a modem connected to a remote PC (or other device) and provide two-way dial-up connectivity to the Public Switched Telephone Network (PSTN). Using the Hayes Compatible ‘ATD+Phone Number’ dialing sequence, the modem can dial or receive landline connections. The diagram below shows how the application may be used as a remote device.

3 Modem Configuration

Modem configuration of the Redwing CDMA modem is done using a terminal emulation program like HyperTerminal in Windows.

IMPORTANT NOTE: Wireless ACE cannot be used to configure the Redwing CDMA modem from a Windows computer. Only a terminal emulation application may be used.

3.1 Local Configuration

1. Attach the antennas, DB-9 cable and power to the back of the modem.

2. Power on the modem, and ensure the On light is lit.

3. Attach the modem to the back of the PC with the provided DB-9 cable.

(Note, if you did not order a cable with your modem, you need a straight-thru RS-232 cable to attach to the modem.)

4. Select Start→ Programs→ Accessories→ Communications→

HyperTerminal.

5. Enter the name of the connection and select OK.

6. For "Connect using" select the COM port that the modem is on (do not select a

modem driver), then select OK.

7. Select 115200 for the "Bits per second." Ensure Data Bits: 8, Parity: None, Stop

bits: 1 and Flow control: Hardware. Then select OK.

(These are the factory default settings for a Redwing CDMA modem. If you get garbled characters when typing AT commands, change these settings and reconnect to the modem. For example, change the baud rate to 57,600 bits per second and connect again, etc.)

8. Type AT followed by [Enter]. You should receive an "OK" in response.

Other AT commands may now be issued to the modem. See Section 5 for a list of AT commands

3.2 Modem Activation [Model C3111]

The activation process is unique for each carrier. See the appropriate CDMA Setup Wizard on AirLink’s web site:

www.airlink.com > Support > Downloads and Support

Documents > Modem Utilities.

3.3 Modem Activation [Model C3110]

The Redwing CDMA modem may be already set up to register online with a phone number, etc. pre-configured into it (by AirLink Communications, Inc.). When a modem is registered on the network and working, the lights will look like the following:

Reset

Note that the Reg light may be flashing at first. When it is registered on the network, it will go solid. Also the Tx (transmit) and Rx (receive) lights will flash as data is transferred to and from the modem on the network.

Redwing CDMA

If your modem lights look like the above when the modem is powered on, you do NOT need to configure the phone number, etc. into the phone and may skip this section.
