Try to de-confuse ad-hoc, demo ad-hoc and ibss:

Browse Source 
o Don't ever refer to ad-hoc mode in the raw.  Instead, refer to it as
  demo ad-hoc mode or lucent legacy demo ad-hoc or some variation on this
  theme.
o Talk about point-to-point modes rather than ad-hoc modes.  Use ibss where
  appropriate.
o Fix type IBBS -> IBSS

Access points are different than operating in IBSS mode.
They operate in BSS mode.
They allow for easier roaming and bridge all ethernet traffic such
that machines connected via an access point appear to be on the local
