the destination mobile computer. This feature can be administratively denied
if a customer requires host logging of RF message traffic.
Data compression services are established when the connection is utilized
between the required MWCS II and the WNG. The effectiveness of
compression varies depending on the content and profile of user messages.
Compression reduces the time required for wireless computers and the
Private DataTAC network to exchange data.
IP header compression services and data compression enhance IP
messaging. IP header compression reduces overhead from 28 to 40 bytes to
an average of eight or fewer bytes.
Data and header compression effectively increase channel capacity by
reducing message transmission time. This compression allows the channel to
support more users and messages or improve response time.

design, see the System Design Guide and the Application Design Guide.
1.3.1.2 Host Connectivity
Private DataTAC 2.0.3 offers both proprietary and industry-standard
network connection protocols. A customer host network can use a single
computer and application program or several computers and applications.
Table 1-1 shows the availability of the protocols and host network
connectivities.

If the customer uses a WNG or FullVision® INM in their system, then
ethernet must be used.
Private DataTAC provides a way to pass data between field user applications
and host network applications through supported host network connection
protocols. FLM and IP host interfaces are available as options.
1.3.2 Network Management
Network management allows a system manager the ability to monitor
network operation. A set of basic reports provide the system manager with
an indication of how the components in the system are performing. Over
time, the system manager can use this information to predict usage trends
that can identify the need for network reconfiguration or future expansion.
