75% of clients in our residence halls connect at 5GHz. When we enabled DFS channels, we saw our 5GHz percentage drop from 65% to 55%, so 75% connected at 5GHz now suggests that 80% to 85% would connect if we limited the 5GHz channels we use. I also know our client match settings are not as effective as band steering at getting clients onto 5GHz (but it’s better for sticky clients and load balancing), so I estimate 85% to 90% of clients on our network are 5GHz capable.
FWIW, 75% connecting at 5GHz now is a 10% to 15% increase from when I last checked in October. I think this is a result of an RF optimization we performed over winter break at least as much as the proliferation of new devices.

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: <mailto:[email protected]> [email protected] <mailto:[email protected]> [email protected] ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at <http://www.educause.edu/groups/> 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/.
