„ AIFS
The Arbitration Inter-Frame Spacing (AIFs) specifies a wait time (in milliseconds) for
data frames. 802.11e uses interframe spaces to regulate which frames get access to
available channels and to coordinate wait times for transmission of different types of
data. The AIFs ensures that multiple access points do not try sending data at the same
time but instead wait until a channel is free. Valid values for AIFs are 1 through 255.
„ Transmission Opportunity
The Transmission Opportunity (TXOP) is an interval of time when a WMM client station
has the right to initiate transmissions onto the wireless medium. This value specifies
(in milliseconds) the Transmission Opportunity (TXOP) for client stations; that is, the
interval of time when a WMM client station has the right to initiate transmissions on the
wireless network.
We recommend that you use the default settings on the WMM QoS
page. Changing these values can lead to unexpected blockages of
traffic on your wireless LAN, and the blockages might be difficult to
diagnose.
4.2.11 Enable Radio eXtended Range
XR is Atheros eXtended technology to increase range. When XR is turned on, the radio
can increase the receiver sensitivity greatly. However, performance may be reduced
significantly also. Use this mode only if you can trade more distance for lower
performance.
