We were considered a similar approach last year but never completed the plan, mainly due to other priorities and having already kind of implemented one. Rather than go a 2.4 and a 5 the plan was to leave our normal network “UofA” as dual and create new network “UofA Premium” or some ‘join me I’m better’ name. We already have a “UofA 5ghz” network so the premium would have simply replaced that and we would have advertised it (website, email etc not broadcast). It was more of a time thing that we didn’t go ahead but now we don’t see it as such an issue. The name change really was about users seeing “UofA Premium” and believing that it would be a better service would attempt to use it over UofA. Where’s UofA 5ghz is technical and means nothing.
As mentioned already 5ghz isn’t always better, so advertising a “premium” service against it may have caused us more issues with higher expectations which might be met in most cases but could be worse if 2.4ghz was a better choice for a location for example. Also devices are now much better at selecting 5 over 2.4 We already offer a 5 only, and users struggling with experience are recommended to try this if they support it. It was first created to deal with some high interference areas where other wireless networks are unavoidable but made it to main campus and some users have found it better…. Or just another one to hop to during issues maybe that could have also been fixed with disconnect/reconnect. ….. So the plan now is continue as we are, we first and foremost recommend UofA with UofA and eduroam configured by our onboarding tool. But we do provide a 5ghz only option to provide for the exception cases. Ideally we’ll remove it one day. -- Jason Cook 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 Mathieu Sturm Sent: Wednesday, 12 August 2015 6:36 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] Exclusive 2.4 Ghz and 5 Ghz SSIDs I agree with Frans, the users in general don’t have the knowledge to decide. They will see 5Ghz, google it and see: oh it’s faster. They don’t realize other factors could make 2.4Ghz the better choice. We have one SSID and let the devices make the right choice.

Mainly because I think Wi-Fi knowledge for the end-user should be minimised. Users should just see the SSID and connect; options to choose from should be minimized. The most important thing users must learn is checking the correctness of the Radius server to whom they give their credentials. For the rest, the device and the Wi-Fi infrastructure should do their very best in serving Wi-Fi users optimaly. Devices in general do a rather good job in selecting the best band. Besides, users have insufficient knowledge in making the right choice between the 2,4Ghz and 5Ghz bands. Note that choosing 5Ghz is simply not always the best choice. If you're too far away from the AP (or because of whether channels or interference on the 5Gh band), the 2,4Ghz band may be the better choice. Good devices switch between the frequencies, to serve users best. You disable that function by introducing separate SSIDs for both bands. -Frans Paul Sedy schreef op 11/08/15 om 22:22: Hello everyone, We are a Cisco shop and have, up until now, employed a single SSID for students, supporting both 2.4 Ghz and 5Ghz connections. During this summer, we have been working to develop sufficient AP density to ensure good 5Ghz cells throughout our dorms. In the past, we have seen numerous instances of poorer performance on the 2.4 Ghz spectrum, but up to this point, have relied on the client to make the decision between these two options. We are thinking of deploying two separate SSIDs, a 5Ghz network and a 2.4 Ghz network, that are exclusive in order to promote a better experience for the students with devices capable of 5Ghz connectivity. We would probably use the original SSID name with an appended (5 Ghz) or (2.4 Ghz). Are any of you currently employing this type of configuration and how well has it worked for you? We would appreciate any insights that anyone might have.
