Two hostap access points in the same computer

1) you're using 11a devices, and this is the hostap (which almost by
definition is 11b in nature) list.
2) somehow you got 30Mbps out of an 11a card, when most of the rest of
the world can't get more than
27Mbps though an otherwise stock 11a AP. Perhaps these radios
aren't performing as APs.
Have you deployed 11e or something?
3) You still have interference. Yes, if S is high enough then the
link will still work. But most locales have
a limit on how high you can take S.
4) Interference is not noise. Noise is non-coherent. Still, if the
S in SINR is high enough compared to I+N,
then the link will work. The issue is that without a lot of work, S
won't be high enough (or rather, I won't
be low enough.)
5) Assuming your 10 deg antennas are pointed to the 4 quadrants, what
do you do to service the other 320 deg
of coverage area?
