It needs to be configured for smooth wireless connection, when using
11b and 11g LAN cards. ‘Auto’ configuration is recommended.
You can configure the period that Beacon is transmitted. 100ms is
normally used. The range of configuration is 20 ~ 999.
When the data longer than configured size is transmitted, it divides the
data into the configured size. If you configure smaller value, the wireless
communication is more stable, but the maximum speed is decreased. If
there are a lot of interferences from other signals, configure the smaller
value for better communication. The range of the configuration value is
‘256 ~ 2346’
When the data longer than configured size is transmitted, the data is
sent in the RTS/CTS method. If you configure smaller value, the wireless
communication is more stable, but the maximum speed is decreased. If
there are a lot of wireless stations to be connected simultaneously,
configure the smaller value for better communication. The range of
configuration value is “1 ~ 2347”.
By changing transmission power, it is possible to control the range of
wireless wave. If you configure higher value, the range is more extended.
If Short Preamble is configured, the performance can be improved, but
the compatibility with some wireless LAN cards can’t be guaranteed. For
the compatibility, use the Long Preamble mode.
Short Slot function can improved the performance of wireless station
connected through 11g mode.
Tx Burst function can maximize the wireless performance. If there are a
lot of wireless stations to be connected simultaneously, turn off this
function for the stable wireless communication.
