DESCRIPTION
Select HT protect if you have devices on your wireless network that support IEEE
802.1b/g standards but not the IEEE 802.1n draft 2.0 standard.
If all devices on your wireless network support IEEE 802.1n draft 2.0, deselect HT
protect for higher data transmission rates.
This is the MAC address of the device.
Type the MAC address of the peer device(s) (the other access point(s) in your
network) in a valid MAC address format, that is, six hexadecimal character pairs,
for example, 12:34:56:78:9a:bc.
Turn on the wireless adapter to allow wireless communications between the
device and other IEEE 802.11b and IEEE 802.11g compliant wireless devices.
Turn off the wireless adapter to stop wireless communications between the device
and other IEEE 802.11b and IEEE 802.11g compliant wireless devices.
Select Yes to enable the grouping of several A-MSDU (Aggregate MAC Service
Data Units) into one large A-MPDU (Aggregate MAC Protocol Data Unit). When
combined with A-MSDU aggregation this function allows faster data transfer
rates.
Select Yes to enable the grouping of small groups of data (MAC Service Data
Units, or MSDU) into one large unit of MSDUs called an Aggregate MSDU (A-
MSDU).
Select Yes to enable RIFS (Reduced Interframe Spacing) and to increase data
transfer rates.
Select Yes or No to enable or disable GI (Guard Interval). The GI refers to the
interval given between data transmission from users in order to reduce
interference. Reducing the GI increases data transfer rates but also increases
interference. Increasing the GI reduces data transfer rates but also reduces
interference.
Set the output power of the device in this field. If there is a high density of APs
within an area, decrease the output power of the device to reduce interference
with other APs.
The options are Full, 50%, 25%, 12% and Min.
Use this field to select a maximum data rate for the wireless connection(s). The
options are Auto, 1 ~ 54M, or MCS0-7.2[15] ~ MCS15-144.4[300].
Select Auto to let the NWA570N decide the most suitable data transfer rate. If you
are not certain of what setting to choose, choose Auto.
Alternatively select a data transfer rate from 1 to 54 Mbps. Please note that this is
a total rate to be shared by all of the device's wireless connections.
The NWA570N also lets you configure the maximum data transfer rate based on
the IEEE802.1n draft 2.0 modulation and coding scheme (MCS). The MCS lists
data transfer speeds given a set of network conditions. The "MCS0" in the MCS0-
7.2[15] option refers to the first set of network conditions and so on. So MCS0-
7.2[15] is appropriate for network conditions which provides data transfer rates of
7.2 Mbps and 15 Mbps at bandwidths of 20 Mhz and 40 Mhz respectively.
