Note: Do not connect the
MP modem to a USB port
on a computer before
installing the software.
The Sierra Wireless MP modem provides a wireless network
connection for portable computers in vehicles or offices.
If the MP modem is installed in a vehicle, it typically is mounted in the
trunk and connected to a notebook computer in the passenger
compartment. A radio frequency (RF) antenna mounted on the roof
of the vehicle enables the MP modem to communicate through a
wireless network to a host computer.
A built-in Global Positioning System (GPS) module provides location
and heading data that can also be remotely monitored.
The MP modem has a rugged design that allows it to withstand the
vibration, shock, humidity, and extremes of temperature experienced
in the normal operation of police, emergency, utility, and field service
vehicles.
You can use the network connection provided by the MP modem to
access shared data, browse the Internet, and send and receive
e-mail and text messages. The MP modem also allows for sensors,
gauges, and alarms (such as panic buttons) to be installed in vehicles
and remotely monitored from a central location.
The MP modem operates over
•Type of wireless network called Code Division Multiple Access
(CDMA). CDMA Third Generation (3G) technology provides a
variety of connectivity features, depending on your service
provider and account.
•1x Evolution-Data Optimized Revision A
(1xEV-DO Rev. A) supports Internet connections with data rates
up to 3.1 Megabits per second (Mbps) downlink from the network
and 1.8 Mbps uplink to the network.
•1xEV-DO Revision 0 (Rev. 0) supports Internet connections with
data rates up to 2.4 Mbps downlink and 153 kbps uplink.
•1x supports Internet connections with data rates up to 153 kbps.

AirLink MP User Guide
62130795
•Circuit switched (dial-up) data, using the earlier CDMA IS-95 specification,
supports data connections to any dial-up service at rates up to 14.4 kbps.
The MP modem is primarily designed to provide 1x or better data connections
but it also allows for Circuit Switched Data (CSD) connections in areas that
have CDMA IS-95 coverage but no 3G high-speed packet service.
Quick Net Connect (QNC) provides a simplified way to dial into an Internet
connection using CSD, assuming CSD is supported by your service provider.
Once a connection is established, you can open your browser and connect to web
sites and access other Internet services such as e-mail.
You must set up an account with a service provider for each MP modem you
install. After installing the MP modem software, you must configure it to use an
account.
The ability of the MP modem to obtain service and the type of service obtained in
any area is determined by several factors:
Network proximity and 1x or EV-DO CDMA availability
To obtain service, you must be within the coverage area of a network operating in
one of the radio frequency bands supported by the MP modem. The type of
connection depends on the service available in that area. For example, there are
areas with 1xservice in which EV-DOhas not yet been implemented.
Roaming If you are within the coverage of a network operated by a different
service provider, your ability to obtain service depends on whether a roaming
agreement exists between your service provider and the one operating your
current local network. There may be additional fees for roaming service. Contact
your reseller or service provider for information.
Account provisions Your account may restrict usage of certain networks or may
limit your connection time or data transmission.
Supported CDMA radio frequencies
CDMA networks operate on two sets of radio frequency bands. The MP modem is
a dual-band product that operates on both bands:
•1900MHz(also called the PCS, or Personal Communications Services,
band)
•800MHz(Cellular band)
Receive diversity
The MP modem supports receive diversity for improved signal reception. Receive
diversity uses two antennas to enhance the quality of the signal, but does not
extend the MP modem’s coverage area.

and monitor the power status of the MP modem.
Setup Wizard
A quick and easy way to activate and configure your MP to connect to the CDMA
cellular network is by using the AceWare Setup Wizard.
Modem Doctor
Modem Doctor is a troubleshooting and diagnostics utility. This utility will allow
you to get a log file of the MP activity which you can then send to Sierra Wireless
support, erase the current configuration completely., and temporarily set the MP
to a known configuration to aid in trouble shooting (SOS mode).

Connection methods
You can connect the MP modem to a USB, Ethernet (RJ45), or serial (DB9) port
on a computer. When connected to a USB or Ethernet port, the MP modem
behaves like a network card. When connected to a serial port, the MP modem
behaves like a dial-up modem.
The MP modem also supports connections via IEEE802.11b/g if you are
implementing a WiFi version.
USB
The MP is equipped with a USB port which increases the methods by which you
can send and receive data from a connected computer. The USB port can be set
to work as either a virtual Ethernet port or a virtual serial port. A driver installation
is required to use the USB port in either mode.
Note: It is recommended that you use a USB 2.0 cable with your MP and connect directly
to your computer for best throughput.
Virtual serial port
The MP modem supports one virtual serial port over USB and one virtual serial
port over Ethernet. This VSP can be used, for example, to send AT commands, or
to run applications such as HyperTerminal.

Special MP modem modes such as GPS that are supported on a serial port are
also available on the virtual port. For example, with the virtual port enabled, a
mapping application on your computer that normally listens for GPS messages on
a serial port listens for those same messages on the virtual port.
Networking
IPSec
IP protocol that drives the Internet is inherently insecure. Internet Protocol
Security (IPSec), which is a standards-based protocol, secures communications
of IP packets over public networks.
IPSec is a common network layer security control and is used to create a virtual
private network (VPN).
The advantages of the IPSec feature includes:
•Data Protection: Data Content Confidentiality allows users to protect their
data from any unauthorized view, because the data is encrypted (encryption
algorithms are used).
•Access Control: Access Control implies a security service that prevents
unauthorized use of a Security Gateway, a network behind a gateway or
bandwidth on that network.
•Data Origin Authentication: Data Origin Authentication verifies the actual
sender, thus eliminating the possibility of forging the actual sender’s identifi-
cation by a third-party.
•Data Integrity: Data Integrity Authentication allows both ends of the communi-
cation channel to confirm that the original data sent has been received as
transmitted, without being tampered with in transit. This is achieved by using
authentication algorithms and their outputs.
The IPSec architecture model includes the Sierra Wireless AirLink modem as a
remote gateway at one end communicating, through a VPN tunnel, with a VPN
gateway at the other end. The remote gateway is connected to a Remote network
and the VPN is connected to the Local network. The communication of data is
secure through the IPSec protocols.

GREGRE
GRE (Generic Routing Encapsulation) tunnel is used to carry non-IP packets
through an IP Network. Non -IP packets, that are send over the GRE tunnel, need
to be first encapsulated. Hence, ALEOS is used to configure and encapsulate
non-IP packets and transmit over IP through the GRE tunnel.
Applications
Events Reporting
Events Reporting is Sierra Wireless AirLink’s modem’s new software feature
provided via ACEmanager and Ace View, that allows the users to generate
reports from the events that take place. Event Reporting Protocol is an intuitive
embedded protocol, which automatically formats the messages based on an
event trigger. The messages generated are then reported to the remote server.
GPS
The Global Positioning System (GPS) is a satellite navigation system used for
determining a location and providing a highly accurate time reference almost
anywhere on Earth. The US military refers to GPS as Navigation Signal Timing
and Ranging Global Positioning System (NAVSTAR GPS).
GPS consists of a “constellation” of at least 24 satellites in 6 orbital planes. Each
satellite circles the Earth twice every day at an altitude of 20,200 kilometers
(12,600 miles). Each satellite is equipped with an atomic clock and constantly
broadcasts the time, according to its own clock, along with administrative
information including the orbital elements of its motion, as determined by ground-
based observatories.
A GPS receiver, such as the MP, requires signals from four or more satellites in
order to determine its own latitude, longitude, and elevation. Using time synced to
the satellite system, the receiver computes the distance to each satellite from the
difference between local time and the time the satellite signals were sent (this
distance is called psuedoorange). The locations of the satellites are decoded
from their radio signals and a database internal to the receiver. This process
yields the location of the receiver. Getting positioning information from fewer than
four satellites, using imprecise time, using satellites too closely positioned
together, or using satellites too close to the Earth’s curve will yield inaccurate
data.
The GPS data is then transmitted to a central location which uses a tracking
application to compile information about location, movement rates, and other
pertinent data.
Note: Depending on the location of the satellites in relation to the modem’s location and
how many signals are being received, the MP may encounter “GPS drift”. The MP may
report it is in a location a few feet from its actual location because it does not employ differ-
ential GPS.

Software
The MP modem comes with the following software:
•ACEview, the software for the MP modem which allows you to manage and
monitor your connections.
•The driver that forms the interface between the MP modem and your
Windows operating system.
•The firmware that is stored in non-volatile memory.
The MP modem has an embedded radio module, also made by Sierra Wire-
less, Inc. There are two firmware programs on the MP modem—one stored on
the controller board of the MP modem and one on the radio module.
The firmware was loaded into the radio module and controller board when the
MP modem was assembled. As new versions of the software and firmware
are released, they are posted at www.sierrawireless.com.
