Preamble Settings a) Shows current value

The radio preamble is a section of data at the head of a packet that
contains information the airPoint™ Device and Remote devices need
when sending and receiving packets.
The pull-down menu shows user to select a long, short or dynamic radio
preamble. Default is dynamic.
Long: a long preamble ensures compatibility with most clients.
Short: a short preamble improves throughput performance. But only allow
short preamble capable clients to associate.
Dynamic: a dynamic preamble allows mixing of short and long preamble.
Throughput Optimizer Throughput Optimizer is used to optimize the radio link speed.
The valid range is 0 to 10. A higher value means the radio will attempt to
establish the highest possible data rate in an aggressive way.
A smaller value ensures a more stable link. The Throughput Optimizer
settings can be varied to achieve a most stable link.
