Al is correct. All the AP's can have the same SSID, but any AP that is
near another AP should be on a different channel. This part is
probably the most challenging as you can only use 3 channels to be
sure that there is no overlap.

I implemented a wireless solution in a corporate HQ using about 70
AP's. Every AP used the same SSID but AP's nearest each other on the
same floor used different channels as far as possible. There were
generally 4 AP's per floor, so two AP's that were diagonally opposite
had to use the same channel. The AP transmit power was set to 1mw, and
we didn't suffer from any problems. We were able to roam around the
whole building with a laptop connected to the WLAN and maintain our
network connection (constantly running a ping -t to a target address,
plus other more demanding tests as well).

The transmit power settings in a warehouse may need to be set
differently though, depending on whether there is high racking or not,
what type of materials are stored, etc.
