If you want a public wifi I would suggest   $50 each and the signal can be hopped up to 3 ap's, and all ap's can be centrally managed.   

They are designed for public places like hotels.  The problem I have with them is that they are actually routers so the laptops connecting to them get open-mesh ip address, which is not so bad but could cause some logging issues.   The advantage here is that if this a just a public wifi there is a check box to isolate the open-mesh network from your current network so it is ideal for public wifi. is another centrally managed ap solution.  Mike Lambert would know more about them then I would.

Dear All:

I am looking to add a public wifi system with centralized AP management.
D-Link has this setup

PoE switch  $350
PoE AP       $90

All of the configuration is done on the switch, and the APs download the SSIDs
and WPA info.

Anyone used these?
