Say Y here if you intend to attach an Atheros Cardbus or PCI
|
|
|
|
|
wireless Ethernet networking card to your computer. This
|
|
|
|
|
driver support the standard Linux Wireless Extensions.
|
|
|
|
|
|
|
|
|
|
You will also very likely also need the Wireless Tools in order to
|
|
|
|
|
configure your card and that /etc/pcmcia/wireless.opts works:

|
|
<http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html>.
|
|
|
|
|
|
|
|
|
|
To compile this driver as a module, choose M here: the module will be
|
|
|
|
|
called ath_pci. If unsure, say N.

SampleRate chooses the bitrate it predicts will provide the
|
|
|
|
|
most throughput based on estimates of the expected per-packet
|
|
|
|
|
transmission time for each bitrate. SampleRate periodically
|
|
|
|
|
sends packets at bitrates other than the current one to
|
|
|
|
|
estimate when another bitrate will provide better performance.
|
|
|
|
|
SampleRate switches to another bitrate when its estimated
|
|
|
|
|
per-packet transmission time becomes smaller than the current
|
|
|
|
|
bitrate's. SampleRate reduces the number of bitrates it must
|
|
|
|
|
sample by eliminating those that could not perform better than
|
|
|
|
|
the one currently being used. SampleRate also stops probing at
|
|
|
|
|
a bitrate if it experiences several successive losses.

Similar to the SampleRate code base, except that it is
|
|
|
|
|
a)more carefully written
|
|
|
|
|
b)shown to give a throughput similar to what can be obtained by
|
|
|
|
|
manually fixing either end to fixed rates
|
|
|
|
|
c)verified by monitoring the network traffic with an ieee80211
|
|
|
|
|
enabled ethereal
|
|
|
|
|
d)responds to network changes and does modify the rate accordingly.
|
|
|
|
|
Thus, on moving the two nodes together/apart, the ideal rate will
|
|
|
|
|
be changed as appropriate.
