The BAD news is that with your setup you can NOT have roaming
capabilities, because for roaming you must have the AP0 and AP1 coverage
area overlapped with the same ESSID and diferent hopping sequence and
the SA0 will associate with the closest AP and only if you can isolate
somehow the SA0 input from AP0 frames by using VERY directional antena
so the SA0 will associate ONLY with AP1 this setup will work. We tryed
that but because of area overlaping and reflections it was not reliable,
somehow the SA0 will allways associate with AP0 after some time and
goodbye link between cells :(. So we take the safe road and use an extra
AP for the link, giving him and SA different ESSID and HOPS, like the
book said ;). This works perfectly AND gives you the seamingless roaming
for those nice users ;)

P.S. I use this beasts for about 2 yrs, from the first models that
appeared before the standard was finshed. So if have a need for help I'm
available for a short contract relocation ;).
