Hi all,
I thought I'd post this here because I know this forum has a lot of knowledgeable networking professionals

I am looking at implementing wireless access at my organization but was hoping for some feedback or opinions on what APs to use. Our building is approximately 18,500 square feet (single story) and was wondering if you think I could find a single AP that would cover most of that by itself?
I was possibly looking at the Cisco Aironet series (1140 probably) because I can get them discounted, but I don't have a whole lot of experience with them.
Was wondering what you all thought? I appreciate any feedback.
