For my home network, I use the same SSID/WPA2-PSK pair on two different
APs on different channels.  One AP is in my house, the other is in my
garage/office, about 150 ft away, and the two wired networks are connected
by a 5GHz 802.11n bridge.  While it doesn't really allow movement between
APs like jumping from cell tower to cell tower, it does make it very easy
to move devices between the two networks (like my phone which will stream
data over Wifi).  I'm sure there are more secure ways to do it, but
wireless in general is a compromise between convenience and security.
