GENERAL DESCRIPTION
MBS2-LP Unit
The MBS2-LP is comprised of an Interactive Satellite Packet Data (ISPD) modem, a General
Packet Radio Service/Enhanced Data-rate for GSM Evolution (GPRS/EDGE) cellular data
modem, and an 802.11b modem, well as associated antennas. It also supports a Global
Positioning Service (GPS) receiver, as well as a Keyfob receiver for Personal Alert.
The MBS2-LP is pictured in Figure 1.
Figure 1: MBS2-LP Front View with Covering
The MBS2-LP is typically connected to a peripheral computer called the Client Side Computer
(CSC) using a tethered serial port connection and/or an untethered 802.11b connection. The
CSC can be a standard laptop or other computing device. The user application and associated
middleware resides on the CSC. The MBS2-LP is capable of supporting some user applications.
The CSC communicates over the Wireless Matrix Wide Area Wireless (WAW) Network via the
MBS2-LP. At the link layer, PPP or the Modem Interface Protocol (MIP) can be used between
the CSC and MBS2-LP.
At the transport layer, the CSC can use UDP to communicate with a Customer Host via the WAW
Network.
WAW Network
The WAW Network, shown in Figure 2, consists of a Data Hub, satellite and terrestrial wireless
networks, and the MBS2-LP unit. WAW is an enterprise solution wireless data service between
remote modems and Customer Host computers, offering seamless coverage with a single point of
connection to the network. This packet-data service can be routed over either Mobile Satellite
Venture’s MSAT-2 satellite or the GPRS/EDGE network
Customer Hosts connect to the Data Hub via Frame, VPN, or leased-line. The Data Hub consists
of:
•Network Operations Support System (NOSS): manages the modems on the WAW
network
•Wireless IP Gateway (WIPG) that connects to the ISPD and GPRS/EDGE networks and
controls data sent between the Customer Hosts and MBS2-LPs.
•ISPD equipment

Wireless Matrix Proprietary and Confidential 7/16
The Wireless Matrix-owned and operated ISPD Network consists:
•Primary Data Hub equipment located at Wireless Matrix in Reston, Virginia
•Secondary Data Hub equipment located in Ashburn, Virginia
•Communications Ground Segment (CGS) located at Mobile Satellite Ventures in Reston,
Virginia
•MSAT-2 geostationary satellite. MSAT-2 covers the United States and its coastal waters
as well as Canada
On the client side, a CSC device connects to the MBS2-LP. The MBS2-LP routes messages
over the Wireless Matrix ISPD Satellite network or the GPRS/EDGE network, depending on
which network the MBS2-LP determines to be the “Active Network”. The MBS2-LP is also
responsible for notifying the WIPG when its Active Network changes.

COMPONENTS
Command Server
The MBS2-LP command server is a logical entity that contains information about routing, MBS2-
LP status, and configuration parameters.
It has a dedicated port number that can be accessed by external entities to make configuration
changes to and queries about the status of the MBS2-LP and wireless network availability. The
command server is accessible by Customer Hosts, client applications, CSCs, and the WAW
Network Operational Support System (NOSS) by using UDP.
Some of the key features of the command server are as follows:
•Initiate the MBS2-LP commissioning process
•Send and receive MBS2-LP Management messages to and from the NOSS
•Provide control of and access to information about the various components within the
MBS2-LP (GPRS/EDGE and Satellite modems, etc.)
•Monitor status of MBS2-LP and its components, and provide status information to the
NOSS or CSC upon request
Satellite Modem
The L-band satellite modem is used to communicate at L-band via the ISPD network. The
modem is provided with an omni-directional cross-dipole antenna. The satellite modem is
designed and manufactured by Wireless Matrix.
GPRS/EDGE Modem
A GPRS/EDGE terrestrial wireless modem is used to communicate on GSM networks. The
GPRS/EDGE modem is a Motorola model G24E GPRS/EDGE OEM module (MS Class 10).
A monopole antenna is used with this modem.
802.11b Modem
The MBS2-LP uses an 802.11b WLAN modem to connect to the CSC wirelessly. By doing so, it
extends the range of a CSC user to several hundred feet from the MBS2-LP. This “Wireless
Tether” also provides good in-building penetration, exceeding 300 feet with a Itronix GoBook
laptop or similar. Outdoor line of sight distances have been tested in excess of 1000 feet with
similar client devices.
The Wireless Tether supports all of the same functionality that a standard serial port connection
supports. The MBS2-LP is capable of routing the communications of multiple CSCs via the
WAW. Also, a CSC using one MBS2-LP may “Roam” to another MBS2-LP and use the latter to
communicate with the WAW network. With this flexible scheme, the MBS2-LP is truly a Base
Station that is mobile.
The MBS2-LP uses the Cisco Aironet 350 PCMCIA card for 802.11b communications. An
elevated dipole antenna is provided. The customer is responsible for providing the CSC with a

MBS-LP EDGE User Guide Document MBUD-0122v1.0
Wireless Matrix Proprietary and Confidential 9/16
wireless modem card capable of communicating with the Wireless Tether modem and approved
by Wireless Matrix.
MBS2-LP supports ad-hoc mode for communications with a CSC, or infrastructure mode for
communications with an Access Point in an In-Yard Communications situation.
The MBS2-LP also has the capability to use the Wireless Tether to communicate with CSCs that
use a sleep mode for power conservation. See the Magic Packet section for details.
The MBS2-LP is capable of the following security methods:
•WEP encryption
•LEAP Authentication
•EAP-TLS Authentication
GPS Receiver
The GPS receiver option includes a GPS receiver and a separate patch antenna.
The GPS receiver is a Navman Jupiter J20, manufactured by Navman. It measures position with
an accuracy of 2.1 meters horizontal, velocity accurate to 0.1 meters/sec, and time accurate
typically better than 1 μs.
The GPS information can be used by the Wireless Matrix AVL application or the application
running on the CSC. Position information can be queried using the gps pos command, or by
configuring the device to send NMEA 0183 v2.2 messages.
The CSC application can access GPS information through command server primitives (refer to
MBS Command Reference Document for details).
Keyfob Receiver
For Alert and Personal Alert features, the MBS2-LP uses a 315 MHz keyfob receiver and
inverted-F antenna. An external keyfob transmitter is also provided.

FEATURES
Multi-Network Routing (MNR)
The Multi-Network Routing (MNR) function enables the MBS2-LP to send communications over
the best available network, as determined by a “Primary Network” setting and the coverage
situation. The routing algorithm is based on a parameter called the “Active Network”, and is
explained in the sections below.
The MBS2-LP is configured during Commissioning to have a “Primary Network”, or a preferred
network. The MBS2-LP will always use the Primary Network as the Active Network when within
Primary Network coverage. The Secondary Network will become the Active Network only if no
Primary Network coverage is available.
For instance, if the Primary Network is satellite, and the MBS2-LP is in satellite coverage, the
Active Network for the MBS2-LP is satellite. If the MBS2-LP leaves satellite coverage but is still
in terrestrial wireless coverage, the Active Network would become terrestrial.
Bandwidth Steering (BWS)
Bandwidth Steering provides a second network path via the MBS2, permitting the full speed of
the GPRS/EDGE network, as well as providing a more economical path for data-intensive
communications. It operates simultaneously with the WAW MNR path.
Bandwidth Steering is based on IP routing rules: all traffic destined for one subnet is routed via
multi-mode network path, while all other traffic is routed to the Bandwidth Steering network path.
Bandwidth Steering is offered as an optional feature, priced separately from the standard multi-
mode service. It enables:
•Large Emails
•Web Browsing
•Large file downloads/uploads
