He means setting up the APs so their channels are as far apart as possible (2 APs should use 1 and 12 or similar highly spread numbers) and making sure there are no blind spots. The latter is supposedly difficult

In addition, only 1 device may be a DHCP server and APs tend to all sit on the same IP, so you'll have to connect to each AP seperately before wiring them all up to ensure that they all use a different IP. Once that's done you can walk about and transparently switch between APs.

Do take note that using APs from more then 1 type might generate problems, just don't do that and you'll be fine
