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 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.

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

1. Introduction

The GSM/GPRS wireless network combines the world’s leading wireless standard—
the Global System for Mobile Communications (GSM)—with fast, packet-switched
access to data networks such as the Internet. Providing this fast access is the
General Packet Radio Service (GPRS).

The AirLink GPRS modems are designed to operate in GSM/GPRS networks. Two
data services are available in the GSM/GPRS networks: GPRS, a packet switched
connection, and SMS, a short message service..

GPRS

GPRS is an IP-based service that offers fast, packet-switched access to data networks
such as the Internet. It is a mobile service that improves the peak-time capacity of a
GSM network. GPRS gives packet-switched access over GSM to external data
networks with high peak transfer capacity. The main objective of GPRS is to offer
access to standard data networks such as TCP/IP. GPRS is a non-voice service
designed specifically for transmitting data. It breaks data messages into separate
packets for transmission from the mobile device and sends them to destinations in an
external network.

Redwing GPRS

User Guide

Most any Internet-based application or service will run on GPRS. GPRS offers peak
throughputs of 40 Kbps (53.6 Kbps raw) Because GPRS capacity is shared among
active users in the same coverage area, actual throughputs may vary.
