[ns] 802.11 ACK frames being sent by APs not RXing data??

[Scott Novich]

Hey all,

I've recently been doing some rudimentary packet collection / statistics
gathering @ the 802.11 layer. In running a simple wireless uni directional
link w/ TCP Newreno and a Sink, it seems ACK frames are being received at
both sides. I know this shouldn't happen at the Traffic/TCP layer (and have
verified this), but is that not the case for 802.11?

Would love to know, thanks!

Best,
Scott
