Re: [WIRELESS-LAN] 5 GHz Only Admin WLAN

[Steve Bohrer]

Just yesterday I was looking at the ticket scanners in one of our theaters,
 (Zebra MC67NA, basically an Android v4.1 phone with a barcode scanner)
because they were connecting at 2.4 rather than 5, and I found that their
Settings > Wifi > Advanced had channel-by-channel enable checkboxes, with
the default setting of only non-DFS channels selected. I checked the boxes
for all the DFS channels, and the scanners joined 5 GHz.

Not sure if this UI setting is in any consumer phones, but it was
interesting to find that level of control on a client device.

It may be obvious, but I should point out that this is regulatory domain 
dependent. For example, my Nexus5 didn't support DFS channels in the US, but it 
did in the EU. I don't now how many other devices are like that, but it's a 
thing.

DFS channels are really well supported on computers and phones released in the 
last two years or so, including the 2e band, and it's a pretty safe assumption 
that in another year or two DFS support for these devices will be a non-issue. 
Those that do have a problem are mostly 2e, though UNII2 isn’t too far behind. 
Many older phones lack any UNII2(e) support, and the three year old Nexus5 
(released about 3.5 years ago) that I just retired a few weeks ago didn’t 
support any DFS channels. 



For other devices, all bets are off. They’re just as likely not to support DFS 
as they are to support it and I don’t know if that will change any time soon.

In response to, “ 2.4 GHz is seeming less and less like a thing to worry about, 
as most devices are already using 5GHz.” I’d caution that 5GHz is a big band, 
and few devices support every channel in it. If you want to get the most out of 
5GHz by enabling DFS channels, you have to give clients that don’t support a 
particular channel something to connect to. I can think of two ways to do that. 
1) You can provide overlapping 5GHz coverage, but that’s only reliable if your 
radio management is smart enough to ensure there’s a non-DFS channels available 
everywhere. I’m not sure any do that yet. 2) Dual-band clients in an area 
covered by a 5GHz channel they don’t support can use 2.4GHz if the SSID 
supports it. 



My recommendation is to leave 2.4GHz enabled if you use DFS channels.

From our side 2.4 being available still ends up with 5Ghz capable client son 
2.4 sometimes and therefore performance issues. So it would be ensuring this 
does not occur.  Our numbers of 5ghz capable connecting at 2.4 sites in the 
20-30% though we have a bit of work to do to understand where this occurs as it 
would be expected in some sparsely covered locations however if it’s  occurring 
in our main areas that should have -67 or better at 5ghz in every corner that’s 
a concern.

Wondering how many of you are running 5 GHz single-band WLAN for admin 
networks, where I’m assuming there is more control over device HW configs. I’m 
specifically contemplating it for an SSID where we use domain-joined laptops.

Been there? Done that? Can you tell me about your t-shirt?

RE: [WIRELESS-LAN] 5 GHz Only Admin WLAN

[Jason Cook]

We run 3 SSID"s essentially doing the same thing but with one 5ghz only. It 
wasn't targeted for  devices where we have more control but as workaround to 
devices connecting at 2.4 when there's a perfectly good 5ghz there.

UofA
UofA 5ghz
eduroam

However I don't like the extra SSID. So the pencilled plan at this point is to 
disable 2.4Ghz on UofA, and remove the UofA 5ghz network. Anyone needing 2.4 
can use eduroam. That would be end of year, so we'll see if it actually happens.

We don't advertise on our website anything about the 5ghz only network, so 
there's no huge take-up which is ok as it wasn't meant to be permanent. However 
it's certainly done its job with users on it no longer having the issue of 
jumping back to 2.4 (including me).

Existing SSID, turn off 2.4.

Wondering how many of you are running 5 GHz single-band WLAN for admin 
networks, where I'm assuming there is more control over device HW configs. I'm 
specifically contemplating it for an SSID where we use domain-joined laptops.

Been there? Done that? Can you tell me about your t-shirt?

Thanks-
