It is possible.  I have this setup running both at home and at the office.

In order for devices to be able to seamlessly switch between access 
points, they must have the EXACT same wifi security setup (SSID, 
security method, and password).  I had a problem with this at work 
trying to use an old router that would not do WPA2.

It can be confusing to figure out exactly which access point you are 
using when the SSID's are all the same.  The Wifi Analyzer app will give 
you the mac address of the router so you can be sure you're using the 
one you think you are.  It's a free app, so give it a try.  I've found 
it to be very useful for dealing with wifi routers and access points.
