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

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

1Introduction
This manual covers information for first-time setup and configuration of your
AirLink PinPoint CDMA modem, as well as technical details on this modem. The
PinPoint is a combination of a CDMA modem and GPS tracking unit. The CDMA
modem allows the PinPoint to report its GPS location to the AirLink Tracking
System main console or to custom applications. The modem may be remotely
configured to report at different time or distance parameters. The PinPoint is also
capable of having its firmware upgraded wirelessly, rendering it unnecessary to
physically connect to the modem to upgrade it.
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. The PinPoint CDMA primarily uses 1xRTT
connections to transmit and receive data.
1.1 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-95 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).

2Network Connection
The AirLink PinPoint CDMA will be capable of offering multiple network connection
options. As of January 2003, the PinPoint CDMA will only use 1xRTT. Circuit
switched and SMS will follow later.
2.1 Internet (TCP/IP) Connections via 1xRTT
When using the PinPoint 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.
NOTE: Connections to Internet are provided by carrier.
Corporate network connections are unique and not provided as part of service.
