Setting RF Network Parameters
The RF Network Parameters screen (see Figure 5-7) enables you to set parameters that control how and
when the client adapter transmits and receives data. To access this screen, select Edit Properties from
the File pull-down menu (see Figure 5-5 on page 5-7) and click the RF Network Parameters tab.
Figure 5-7
Table 5-4 lists and describes the client adapter's RF network parameters. Follow the instructions in the
table to initially set or change any parameters.

RF Network Parameters
Description
Defines the threshold above which an RF data packet is split up or
fragmented. If one of those fragmented packets experiences interference
during transmission, only that specific packet would need to be resent.
Throughput is generally lower for fragmented packets because the fixed
packet overhead consumes a higher portion of the RF bandwidth.
Range: 256 to 2312
Default: 2312
Defines the number of times a packet is resent if the initial transmission is
unsuccessful.
Range: 1 to 128
Default: 16
Note
If your network protocol performs its own retries, set this to a
smaller value than the default. This way notification of a "bad"
packet will be sent up the protocol stack quickly so the application
can retransmit the packet if necessary.
