I would add that with the forthcoming 802.11ax, improvements are also being extended to 2.4, meaning the life-span of 2.4 is being reset in some form. As such, we’ll likely see devices continue in 2.4 for many years, especially those that benefit from staying anchored to the same AP (less roaming).

So many people try a 5GHz only and a 2.4Ghz only and it backfires on them.

So we are stuck with making them work but in doing so we see 5ghz capable devices sitting on 2.4 which isn’t so good. The extra SSID was fired up as a test and worked, so got stuck there but we still don’t classify it under our production since it’s poorly named. For end of year I’m proposing the removal of “UofA 5ghz” and making “UofA” a 5ghz only SSID with eduroam covering both 5 and 2.4. Our users get the same service on eduroam anyway as they would on our branded SSID(ip connectivity wise). A few years back I posted a discussion about this where we were considering something similar but having a 2.4ghz only network as UofA-legacy or the 5ghz network as UofA-Premium etc. since the current “UofA 5ghz” is technical and users don’t know what it means. We never got to a point where we were fully happy with the plan but in general we preferred the idea that if your 2.4ghz only you go on something called legacy to help drive the idea that they would ideally not use such a device. -- Jason Cook Technology Services The University of Adelaide, AUSTRALIA 5005 Ph : +61 8 8313 4800 From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of Casey Feskens Sent: Tuesday, 7 March 2017 4:58 AM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU<mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU> Subject: Re: [WIRELESS-LAN] 2.4 vs 5 We are currently using a 5GHz only SSID (as well as 2.4) and have been trying to encourage students to use it. We recently conducted a survey of wireless performance and asked questions about why people were using 2.4 networks vs. 5GHz. A surprising number of students replied that their devices could not see the 5GHz SSID.

Sessler <j...@scrippscollege.edu<mailto:j...@scrippscollege.edu>> wrote: I don’t think there is a way to get away from 2.4 yet in EDU. For example, while most would install high-density 5GHz in every residential room, it’s likely cost-prohibitive to accomplish the same in hallways and other areas that devices transit but don’t linger. As such, 2.4 is still important for “in flight” devices.
