User Applications
The MBS2-LP supports multiple User Applications residing in its firmware. The User Applications
can total 64kB in size. One specific type of User application is Wireless Matrix AVL.
Alert and Personal Alert
The Alert and Personal Alert features can be used to inform the Customer Host of an important
event, such as driver in danger or “man-down” messages. The Customer Host would be able to
distinguish between a keyfob or vehicle button activation.
The Alert message is generated by the closing of an electrical contact, and the Personal Alert
message is generated by a keyfob. The wireless keyfob signal can be received by the MBS at a
distance of 150 feet.
The message is sent with location information and truck identification by using the Wireless
Matrix AVL application.
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 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.
Type of Data Rate ISPD AWS GPRS
Raw 6.75 kbps 42.8 to 64.2 kbps
After Overhead, channel sharing
(Estimated)
0.3 to 0.6 kbps 4 to 8 kbps
Table 1: MBS2-LP Underlying Networks Throughput Comparison
Note that since the underlying networks are transparent to the MBS2-LP user, the actual
throughput depends on the current Active Network. A minimum throughput is not guaranteed.
