Redwing GPRS - User Guide, version 2.30 1

CHAPTER 1 Introduction to Redwing GPRS

The Redwing's rugged form factor is ideal for industrial and commercial applications that require

real-time communications. The Redwing provides cellular data communications for a variety of

applications, such as telemetry, public safety, SCADA, traffic control, traffic metering, transit

arrival systems and more.

FIGURE 1. Redwing front and back

GPRS Overview

Establishing an Internet Connection

The Internet Service Provider (ISP) from you to the Internet is Your Wireless Service Provider with

your Redwing as the connection to Your Wireless Service Provider.

General Packet Radio Service (GPRS) is packet-switched with many users sharing the same

transmission channel, but only transmitting when they have data to send. This means that the total

available bandwidth can be immediately dedicated to those users who are actually sending at any

given moment, providing higher utilization where users only send or receive data intermittently.

GPRS provides speeds of 30–70 kbps with bursts up to 170 kbps.

Redwing GPRS - User Guide, version 2.30 2

Introduction to Redwing GPRS

Steps of a connection:

Using the GPRS Network

As stated above, when your Redwing registers on the Your Wireless Service Provider network, it

receives an IP address. There are two types of addresses on networks: dynamic and static.

•Dynamic addresses are assigned on a “need to have” basis. Your Redwing might not always

receive the same address each time it connects with Your Wireless Service Provider.

•Static addresses are permanently assigned to a particular account and will always be used

whenever your Redwing connects to the Internet. The IP address will not be given to anyone

else.

How your Redwing gets its IP Address from Your Wireless Service Provider

1. When your Redwing is powered on, it automatically searches for cellular service using GPRS.

2. Your Redwing establishes a PPP (Point to Point Protocol or “dial” up connection) link to Your

Wireless Service Provider’s network, also called registering on the network, and receives an IP

address from Your Wireless Service Provider.

3. When your Redwing has received the IP address from Your Wireless Service Provider, then it

is ready to allow communication to the cellular network.

To use your Redwing’s serial port to connect to the Internet from your computer, you need to con-

nect the computer directly to the Redwing’s serial port and use Dial-Up Networking (DUN).

Introduction to Redwing GPRS

Private network connections are unique for each configuration and not covered as part of the stan-

dard installation.

Dynamic vs Static IP Addresses

If you need to contact the Redwing, a device connected to the modem, or a host system using the

Redwing from the Internet, you need to have a known IP (such as one which is static) or domain

name (an IP address which is converted by a DNS server into a word based name).

Most ISPs (cellular included) use dynamic IP addresses rather than static IP addresses since it

allows them to reuse a smaller number of IP addresses for a large number of customers. A

dynamic IP address is suitable for many common Internet uses, such as web browsing, looking up

data on another computer system, or other client functions (such as data only being sent out or only

being received after an initial request).

Common Uses for the Redwing

With GPRS, you can choose a type of Access Point which most suits your needs. Your Wireless

Service Provider can set up your account so you are able to have a Private IP address, a Public IP

address, a static IP address, or even a custom IP address which essentially extends your com-

pany's local area network to include the Your Wireless Service Provider network. The Access

Point is the link to the type of network with the Access Point Name (APN) as the gateway. It sets

up the DNS and other configurations needed to communicate on that network.

For most accounts, the default “Internet APN” is the connection you will need and want to config-

ure for your . Contact Your Wireless Service Provider to find out if your account is set up differ-

ently or uses a different APN.

Note: If you have a dynamic IP address for your Redwing, you will not be able to

contact the modem using a name.

Caution: The IP address given to your Redwing by Your Wireless Service Provider

must be Internet routable if you do not have a direct connection to the Your Wire-

less Service Provider's network (example, using frame relay).

The Redwing’s rugged construction and cellular connection make it ideal for use in remote and/or

industrial locations.

The Redwing is designed to work with legacy devices which do not need the advanced features of

ALEOS.

CHAPTER 2 Activating the Redwing

The SIM (Subscriber Identity Module) card in the Redwing is a smartcard securely storing the key

identifying a mobile subscriber. Generally, you will only need to install the SIM once in the life of

the modem and it may be pre-installed by AirLink.

Installing the SIM

To install the SIM, you will only need a small phillips head screw driver.

a. Unplug the Redwing’s power and all cables.

b. Using a small phillips head screw driver, remove the screws on the back of the Redwing.

c. Slide the casing off of the Redwing and set it aside.

Note: If the SIM card was pre-installed by AirLink, unless you need to set a custom

APN, there is nothing more you need to do, activation of your modem is complete.
