I can only speak from our experience. We went from portal to no-portal and saw a large increase in dhcp lease usage.
As best as we can determine, if there is not a portal, many mobile clients keep probing to verify that Internet access is still available. This lets the device inform the user there is a usable wireless Internet connection available. If there is a portal, they seem probe less aggressively.

We had a wide open Guest network for a while until there were DHCP capacity issues. We then inserted a portal to fix that.

You may want to also know the answer to “who has done this and switched back to a non-open environment?”. -Brian From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[email protected]] On Behalf Of Lee H Badman Sent: Friday, May 13, 2016 9:02 AM To: [email protected]<mailto:[email protected]> Subject: [WIRELESS-LAN] One more round- finer point on Open Networks in Dorm I asked this back in February, and would like to go one more round with some specifics applied. Direct response off-list is OK if you prefer. Let me ask it two ways: · Who runs a wide-open WLAN in their dorms? I’m talking no encryption, no portal, no nothing. Just get on and go, baby. · Same question, but with simple PSK/WPA2 added. No ISE, no Clearpass, no MAC registrations. For those doing this, do you rate-limit? Restrict access only to Internet? Block WLAN clients from directly reaching each other? Any other restrictions/policy configs applied?
