Just to add a little to VaV's post; - The APs will handle the routing/back end. No worries about managed switches.
- You can specify the IP scheme: the address range and amount of DHCP clients- As a Guest Network it will isolate clients from your Corporate networks and from each other.
- If you have the need, you can specify IP addresses that you grant guest users access to, in addition to internet access.
- You can limit bandwidth and specify a schedule that the guest network is active.
- You can create a custom guest portal, no additional equipment needed (and it's pretty decent, too)Hope this helps a bit.
