contains information the Root Device and Remote devices need
when sending and receiving packets.
The pull-down menu user to select a long, short or dynamic radio
preamble. The default is dynamic.
Long: a long preamble provides stable link
Short: a short preamble improves throughput performance. But it only
allows short preamble capable Remotes to be associated.
Dynamic: a dynamic preamble allows mixing of short and long
preambles

sB Enhanced Mode gives better performance with the compression
option. For this reason, it does not support 802.11b
Throughput
Optimizer
The Throughput Optimizer is used to optimize the radio Link speed
and performance.
The Valid range is 0 to 10. The default value is 6.
Setting a higher value will cause the radio to attempt to establish at
the highest possible data rate in an aggressive way. A smaller
"Throughput Optimizer" value means a more stable link.
Note: The default value for the Throughput Optimizer is 6. Vary the
Throughput Optimizer settings to achieve a more stable link.
