OBSS matters. OBSS is not just two APs overlapping
PCF, HCCA have struggled in the marketplace
Partly because of fragile behavior in corner cases
Under-designed and therefore irrelevant
OBSS in 2.4 GHz is routine
OBSS at 5 GHz is much less likely, but still matters with:
40 MHz operation
DFS not implemented or certified (e.g. IBSS)
Poor channel selection
Moving APs
Nearby radar
