I've been doing a lot of research on various Cisco wireless products and the options are kind of confusing.
I'll start with my deployment; I have two locations both of which have a manufacturing and warehouse environments (no climate control) and regular offices.
Location 1 needs 3 APs on the production floor and 1 in the offices.
Location 2 needs 5 APs on the warehouse floor and 4 for the offices.
I was thinking about using the Cisco 521 APs for both the production floor and offices and the Cisco 526 Wireless Controller for Location 1. I figure that will give them room for expansion and keep the costs low.
For location 2 I was thinking about the Aironet 1240AG APs for the warehouse floor, Aironet 1140AG APs for the offices and then a Cisco 2112 Wireless Controller to manage all the APs.
Both locations require WPA (or WPA2) encryption and roaming.
My questions are:
Will the 521 APs work with the 2112 controller? For that matter, what sort of interoperability is there with the APs and controllers? Can I manage any Cisco AP with any Cisco Controller?
Are there any cheaper APs than the 1140AG that will work with the 2112 controller?
Is the 1240AG a good choice for a non-climate controlled warehouse environment? The APs are going to be mounted on the ceiling which is roughly 50 feet high and I'm going to be very upset if I deploy these APs and then have one fail during the summer 6 months later because it wasn't made for volatile environments.
The 521 APs are only going to be about 15 feet up so they can be accessed with a ladder so I'm not so worried about them.
