From our side 2.4 being available still ends up with 5Ghz capable client son 2.4 sometimes and therefore performance issues. So it would be ensuring this does not occur. Our numbers of 5ghz capable connecting at 2.4 sites in the 20-30% though we have a bit of work to do to understand where this occurs as it would be expected in some sparsely covered locations however if it’s occurring in our main areas that should have -67 or better at 5ghz in every corner that’s a concern.

Are you trying to minimize the amount of (limited) 2.4 GHz bandwidth taken by beacons? Or do you just want to assure that the devices you care about don't inadvertently grab a slow 2.4 connection? We are way smaller than you guys, but just with Aruba doing its standard ARM stuff, typically less than 10 percent of our connected devices are on 2.4 GHz. The majority of these are are "registered" student devices that can't do 802.1x or 5GHz, mostly game machines. Of the rest, many seem to things that have hopped on our "guest" network but then not actually signed in at the portal. My assumption has been that these are phones in the pockets of the many non-Emerson people who walk by our buildings. So, 2.4 GHz is seeming less and less like a thing to worry about, as most devices are already using 5GHz.

It wasn’t targeted for devices where we have more control but as workaround to devices connecting at 2.4 when there’s a perfectly good 5ghz there. UofA UofA 5ghz eduroam However I don’t like the extra SSID. So the pencilled plan at this point is to disable 2.4Ghz on UofA, and remove the UofA 5ghz network. Anyone needing 2.4 can use eduroam. That would be end of year, so we’ll see if it actually happens. We don’t advertise on our website anything about the 5ghz only network, so there’s no huge take-up which is ok as it wasn’t meant to be permanent. However it’s certainly done its job with users on it no longer having the issue of jumping back to 2.4 (including me). -- Jason Cook Technology Services The University of Adelaide, AUSTRALIA 5005 Ph : +61 8 8313 4800<tel:+61%208%208313%204800> From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[email protected]<mailto:[email protected]>] On Behalf Of Lee H Badman Sent: Friday, 24 March 2017 11:21 AM To: [email protected]<mailto:[email protected]> Subject: Re: [WIRELESS-LAN] 5 GHz Only Admin WLAN Existing SSID, turn off 2.4.
