Table 4-3
Wireless Station configuration parameters
Item
Description
Wireless Mode
Select from 802.11b/g (the default) or 802.11b/g/n.
Guard Interval
Select whether to automatically set the guard interval (Auto), or to use a Long (800 ns)
or Short (400 ns) interval. Guard interval is the space between transmitted symbols
(characters). Can eliminate inter-symbol interference (ISI), which occurs when echoes or
reflections from one symbol interfere with another. A long interval can reduce echoes,
but decrease the data rate. A short interval can increase the data rate by approximately
10 percent.
NOTE:
This parameter only displays when
Wireless Mode
is set to 802.11b/g/n.
Enable AMSDU Aggregation
Select whether to enable aggregation of MAC service data units. Aggregating 802.11
MAC service data units packs them into frames to reduce overhead and increase the
data rate. Enabling aggregation allows a maximum frame size of 7935 bytes.
NOTE:
This parameter is only displayed when the 802.11b/g/n
Wireless Mode
is
selected.
Enable AMPDU Aggregation
Aggregating 802.11 MAC protocol data units packs them into frames to reduce
overhead and increase the data rate. Enabling aggregation allows a maximum frame
size of 64k bytes.
NOTE:
This parameter is only displayed when the 802.11b/g/n
Wireless Mode
is
selected.
Enable Block ACKs
Select whether to enable acknowledgment of multiple AMPDUs, which allows each of
the aggregated data frames to be individually acknowledged or retransmitted if affected
by an error.
NOTE:
This parameter is only displayed when the 802.11b/g/n
Wireless Mode
is
selected.
This parameter is automatically selected when
Enable AMPDU Aggregation
is
selected.
Wireless Wizard
Launch the wireless configuration wizard, which guides you through the required 802.11
wireless configuration parameters and, depending on your choices, bypasses
unnecessary parameters. Because the individual Wireless configuration parameters are
documented in this table, the Wireless Wizard is not discussed.
NOTE:
If you improperly exit the wizard, for example by failing to use the Cancel
button, an Operation Failed screen might appear. If so, wait approximately two minutes
before restarting the wizard.
Wireless Radio
Click the
Enable Wireless Radio
button to enable the wireless radio. Click the
Disable
Wireless Radio
button to disable it.
NOTE:
The HP Jetdirect print server cannot operate in wireless mode when the radio
is disabled.
