The Airgo chipset is a pre-n product, and the feature to support

now, I'd glad to do.
Oh, ok, do you know what's different between the pre-N implemented by
this chip and standard-N (say draft 2.0 or so)?
I am aware of 3 flavors: pre-N (pre 802.11 working group, like Airgo),
D1.x 11n, D2.x 11n. Getting D1.x and D2.x cards to interop isn't a big
deal (at least at some reduced level of operation). Several things make
this confusing:
1. retail labeling is unclear
2. chips are being rev'd quickly so retail products are typically out of
date
before they hit the shelves
3. 11n isn't ratified so in the meantime various groups have defined
test plans
for interop and compliance w/ one plan doesn't necessarily mean you
interop w/ the other(s)
Now is definitely the time to be doing 11n. There is significant effort
getting up to speed on all that is involved.
