This is a question of use-cases. In a city yes there are many
hotspots but also yes they're sparsely distributed - you must handover
to something else in between. In a home network they'd be densely
distributed, could hand-over directly, or not at all.
Actually they're pretty densely distributed around me.
There's one AP per household (via the cable TV provider) which has an
SSID for dedicated use.
These also support the guest/roaming access using a common SSID
identical on all APs.
There are 5 apartments within wifi range of my desktop (I can see that
via the dedicated SSID).
And I find 12 on my mobile if I walk to the balcony.
You could be moving a lot and never handing over, as much as you could
sit and do many hand-overs per second.
Such use-cases and reqs are described in DMM WG documents.
ACK

It might
have to do with IEEE and IETF mismatch. Same SSID shall have same IP
subnet (IEEE) versus each link has its own subnet (some of IETF, no
formal statement...).
Of course, if every SSID has its own 192.168.0.0/24, oups, this is
legacy
IP, so, not a Homenet topic :-O
Sorry could not resist
