I'm sure one of you have done this before. So our company has decided to have a separate physical network for Guest WiFi. This means putting up a new Cisco Wireless Controller and Access Points. We will also put it on the edge of our LAN, making sure that it's touching only the router of our 2nd ISP.
My question will be the (possible?) interference these additional Guest APs will bring. Currently we have 4 APs we are using for our Corporate users. Our office has two floors with about 100+ users. I'm thinking of putting up 2-3 Guest APs. Where do you suggest to put them? Should I place it as far as possible from the Corporate APs? Or can they be close, assuming that it's 5 GHz and they are using different channels. Any best practice or suggestions?
Thanks as always.
