We have some management with Visio TVs that requires 802.11b rates in order to associate. That presents a challenge too.

I'm unfortunately seeing that we may actually start to experience an INCREASE in 2.4GHz-only devices ..... when we asked about this on campus recently, I received this reply ... and this is from a central IT person: " I wanted to point out that many brand new phones don't speak 5GHz such as the Motorola Moto G (3rd generation) which just began shipping late last summer. In fact, none of the generations of Moto G have a 5GHz radio. Motorola has reserved 5GHz wifi for the Moto X which is their premium spec phone. The Moto G is a pretty common phone - I know of several folks (in our department) that have such including myself and a coworker who just bought a brand new one Friday. Republic Wireless sells a ton of these. The Moto E, which is the base model, also doesn't speak 5GHz. Several folks in our building also have that phone." Don't know whether to blame Motorola or folks that go for the cheapest stuff possible. -- Jim Gogan / Univ of North Carolina at Chapel Hill -----Original Message----- From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of Earl Barfield Sent: Monday, April 11, 2016 4:07 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] Turning off 2.4 on a select SSID? > On 04/07/2016 09:24 AM, Hector J Rios wrote: >> >> I guess this brings up another good question, and that is, what is >> the percentage of 5GHz vs 2.4GHz you all see in your institutions? >> For us is still 50-50.

In our environment, it varies wildly by building: some as high as 95% of sessions and others, such as our outdoor spaces, down close to zero. We focus our resources on improving the 5GHz coverage in the buildings with the lower percentages. All this data is in the Airwave Management Platform database. It just takes a little gentle coaxing to get it out. In our high density spaces, we have many many APs on 5GHz with directional antennas, along with turning of lower data rates and raising RxSOP to limit the cell size. We turn off 2.4GHz radios on all but a few APs in the room, From the user side, this should look about like APs with multiple 5GHz radios. We're using Cisco AP3702Es right now but we're anxious to take a look at the upcoming AP3802Es that should allow us to use fewer APs to but the same number of 5GHz antennas serving a room. -- Earl Barfield -- Academic & Research Tech / Information Technology Georgia Institute of Technology, Atlanta Georgia, 30332 Internet: earl.barfi...@oit.gatech.edu e...@gatech.edu ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
