MISCELLANEOUS
Addressing
All components of the WAW system are addressed using IP addressing. Customer Hosts,
MBS2-LPs, and CSCs are designated IP addresses in the following subnet range: 10.128.0.1 to
10.254.255.254.
From the Customer Host point of view, the CSC IP address may be statically assigned or
dynamically assigned using WDHCP. The pool of addresses used for assignment shall be
specified by either the Customer or Wireless Matrix personnel.
Ports 51000 to 51999 shall be reserved for User Applications residing on the MBS2-LP.
Throughput
MBS2-LP throughput on the WAW network is almost entirely dependent on the throughput of the
underlying ISPD and GPRS/EDGE networks. Raw data rates are known, but actual throughputs
are estimated, based on the fact that multiple users share the over-the-air channels.
Table 1 lists the data rate information for each network.

Actual rate 0.3 to 0.6 kbps 10 to 25 kbps 70 to 115 kbps
Table 1: MBS2-LP Underlying Networks Throughput Comparison
Note that since the underlying networks are transparent to the MBS2-LP user in MNR, the actual
throughput depends on the current Active Network. A minimum throughput is not guaranteed.
Tools
Wireless Matrix provides two tools to assist the developer on the WAW system: Wireless Matrix
Chat and Communicator. The tools are Open Source license tools distributed in code form. This
provides complete visibility for the developer and enables straightforward extensions to the
program that the developer may want to add.
The Wireless Matrix Chat program was created to provide simple chat sessions over the air from
Customer Host to MBS2-LP or from MBS2-LP to MBS2-LP.
The Communicator is similar to the On-Board Computer (OBC) application used in the Wireless
Matrix X.25 network. It allows an operator to:
• Edit and send messages to an arbitrary IP address
• Send a file of arbitrary size to an arbitrary IP address
• View the text of messages received by the Communicator
• Monitor the operational status of the MBS2-LP
• Monitor the signal strengths of the networks to which the MBS2-LP is connected
• Access the Command Server of the MBS2-LP
