I need to deploy several APs in somewhat close proximity. Each AP will be in a separate room, servicing the users in that room, and each AP will run on a non-overlapping channel. Someone recommended that I configure each AP with a unique SSID as a way to force users in Room 1 to associate to AP 1, users in Room 2 to associate in AP 2, and so on. But I'm unsure if that will add any benefit, especially considering that other factors such as AP signal strength will make sure that the users associate to the AP with the strongest signal (which will be the AP in their room). If anything, I suspect configuring each AP with a unique SSID will add complexity to the setup (what if a user from Room 1 goes into Room 3? Now he/she won't be able to access the network).
I'm inclined to have one single SSID for simplicity. Any thoughts?
