Close. UMA uses Wifi for the 'last 10 metres', so requires a special
handset.

From this armchair general's perspective, picocells make more sense than UMA
as they don't require a special handset. I'm not sure if UMA also requires a
special wifi AP, if so it makes even less sense. I'm sure there are
compelling reasons for UMA over picocells.
