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.

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.
•
