Limitation of
Liability
Due to 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 Sierra Wireless modem are used in
a normal manner with a well-constructed network, the Sierra
Wireless 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. Sierra
Wireless accepts no responsibility for damages of any kind
resulting from delays or errors in data transmitted or received
using the Sierra Wireless modem, or for failure of the Sierra
Wireless modem to transmit or receive such data.
Do not operate the Sierra Wireless 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 Sierra Wireless modem
MUST BE POWERED OFF. The Sierra Wireless modem can
transmit signals that could interfere with this equipment.
Do not operate the Sierra Wireless modem in any aircraft,
whether the aircraft is on the ground or in flight. In aircraft, the
Sierra Wireless modem MUST BE POWERED OFF. When
operating, the Sierra Wireless modem can transmit signals that
could interfere with various onboard systems.
Note: Some airlines may permit the use of cellular phones while the
aircraft is on the ground and the door is open. Sierra Wireless
modems may be used at this time.
The driver or operator of any vehicle should not operate the
Sierra Wireless 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
offence.
The information in this manual is subject to change without
notice and does not represent a commitment on the part of

The Sierra Wireless MP modem provides a wireless network
connection for portable computers installed in vehicles.
The MP modem is usually installed in the vehicle’s 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.

Figure 1-1: The MP modem and the network.
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.
Network connections
The MP 875 modem operates over the following networks,
with connectivity and speed dependent on your service
provider and account:
• High Speed Downlink Packet Access (HSDPA)—up to
3.6 megabits per second (Mbps).
12 2130808

Introducing the MP 875 Modem
• Universal Mobile Telecommunications System (UMTS)—
up to 384 kilobits per second (kbps).
• Enhanced Data GSM Environment (EDGE)—up to
236 kbps.
• General Packet Radio Service (GPRS)—up to 56 kbps.
• Circuit switched (dial-up) data connections.
Once a connection is established, you can open your browser
and connect to web sites and access other Internet services
such as e-mail.
Accounts and coverage
You must set up an account with a service provider for each
MP 875 modem you install. After installing the MP 875 modem
software, you must configure it to use an account.
The service provider supplies a Subscriber Identity Module
(SIM) card—sometimes called a smart card or smart chip—for
each account. The SIM card provides the MP 875 modem’s
identity on the network. It contains account information and
must be inserted in the MP modem for the MP modem to
operate. (See “Inserting the SIM Card” on page 32.)
The ability of the MP 875 modem to obtain service and the
type of service obtained in any area is determined by several
factors:
Network proximity and HSDPA 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 875 modem. The type of connection depends on the
service available in that area. For example, there are areas with
UMTS service in which HSDPA has 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.
Rev 1.1 Aug.07 13

MP 875 Modem User Guide
Supported GSM radio frequencies
The MP 875 modem has tri-band capability on HSDPA and
UMTS networks, operating on:
• 850 MHz
• 1900 MHz
• 2100 MHz
and quad-band capability on EDGE and GPRS, operating on:
• 850 MHz
• 900 MHz
• 1800 MHz
• 1900 MHz
USB, Ethernet, or serial
computer connection
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.
Virtual serial port
The MP modem supports four virtual serial ports (VSPs).
Three are reserved for internal use by the MP modem. The
remaining VSP, which is called Sierra Wireless Application
Interface 2, is assigned to a specific COM port that varies
between users. 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.
The MP modem virtual serial port is available on both USB
and Ethernet interfaces. For information on enabling a virtual
serial port, see the MP 3G Modems AT Command Reference
(document #2130810).
14 2130808

Introducing the MP 875 Modem
VPN support for RNAP
This feature allows for the exchange of Remote Network
Access Protocol (RNAP1) data between the MP modem and a
remote server accessible only through a Virtual Private
Network (VPN) connection. When using this feature, you must
have 3G Watcher running on the computer.
The MP modem sends RNAP data over Ethernet or USB to 3G
Watcher on the computer. 3G Watcher places the RNAP data in
a User Datagram Protocol/Internet Protocol (UDP/IP) packet
and sends it over the VPN connection to the server. When 3G
Watcher receives a UDP/IP packet containing RNAP data over
the VPN connection, it disassembles the packet and sends the
RNAP data to the MP modem.
You can enable this option using 3G Watcher software or AT
commands. See the 3G Watcher online help and the MP 3G
Modems AT Command Reference (document #2130810) for
details.
Software
The MP modem comes with the following software:
• 3G Watcher, 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 875 modem has an embedded radio module (a
Mini Card 8775), also made by Sierra Wireless, Inc. There
are two firmware programs on the MP 875 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 con-
troller board when the MP modem was assembled. As new
versions of the software and firmware are released, they
are posted at www.sierrawireless.com.
1. RNAP is a Sierra Wireless proprietary protocol that encapsulates the
MTP data that is sent to and from the MP modem. It ensures that the
MP modem and remote host alike recognize the data packets. See The
Monitoring and Tracking Protocol Guide on page 17.

MP modem’s performance is affected by the type of
Ethernet card in the computer and the type of cable
used. The minimum requirement for the Ethernet cable
is an unshielded twisted pair (UTP) cable, category 3 or
4. For better performance, use a shielded, category 5
cable. The maximum length is 100-m (328 feet).
