Re: [WIRELESS-LAN] Roku clients & 5 GHz DFS channels.

[Norton, Thomas (Network Operations)]

Hey Raf,

I have verified this in my personal testing and reached out to Roku to confirm. 
Our dorms are so dense it hasn’t been an issue for us, but we did complete a 
considerable amount of testing and validation before going forward with DFS 
channels in our residential/academic environments. Especially being LU has an 
app we use all over campus with Roku devices.

 In our testing the impact was very minimal, though I do attribute it to proper 
coverage (primary/secondary)planing/tuning. As well the benefit of airtime is 
to great. It is something to always be mindful of though.

I think we have had one ticket in the last two years around DFS issues with a 
Roku insignia tv and it ended up being a configuration adjustment on our end.

Also - that client compatibility list is amazing, it has come in handy quite a 
bit over the years.

GHz, as well as having taken a look at the list on 
clients.mikealbano.com.  Has anyone come across 
the same realization?  Has anyone been in contact with Roku to verify this?

For those of you in charge of Wi-Fi deployments in residence halls, do you do 
anything to address these?  Do you limit your channel plan to UNII-1, UNII-3 
bands?  Or do you simply not bother going out of the way to plan for these 
devices?

TIA,

This is far from authoritative, but according to some random person on the roku 
forum:

Good to know and really surprising.
