actually this is exactly what we did. We changed antennas and turned
down the txpwr. Also works.

But we had some 24dBi investments on the roof that we could have kept up
there :)

A has a better chance of being always selected as the receiving antenna
because it is a high gain antenna.

Yes, the mail by jim thompson seems like quite an opportunity.
Atheros home brewn-beamforming hm... nice 

anyway, point is: we guys in berlin, vienna and Cuwin should work more
closely together. There is lots of know how and we tend to reinvent the
wheel far to often. For example in VIE we are planning to create our own
linux FW for www.osbridge.com (5gxi model) . We have nice experiences
with it (1.7mBytes ~ netto transfer rate) and we want to have olsr on
it. This setup is very nice pointo to point link with little
interference in other parts of the mesh (5ghz -> many channels). Maybe
at CUWin you would be interested to see how it performs with HSLS
(BTW: what cpu power do you need for HSLS?)
