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. And it’s been like that for a while. I still see new
laptops that only come with 2.4GHz adapters.
While it can be useful to track what percentage of connections use 5GHz
radios, we've found that a better question to ask is "What percentage
of 5GHz-capable clients are actually connecting at 5GHz".
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.
