Example
preamble
This command sets the length of the signal preamble that is used at the start of a
802.11b/g data transmission.
Syntax
preamble [long | short-or-long]
• long - Sets the preamble to long (192 microseconds).
• short-or-long - Sets the preamble to short if no 802.11b clients are
detected (96 microseconds).
Default Setting
Short-or-Long
Command Mode
Interface Configuration (Wireless - 802.11b/g)
Command Usage
• Using a short preamble instead of a long preamble can increase data
throughput on the access point, but requires that all clients can support a
short preamble.
• Set the preamble to long to ensure the access point can support all 802.11b
and 802.11g clients.
