Ruckus AP capacity planning/formula

[samuel_eng]

Ok,

CLIENTS: Single stream, 802.11ac

Connected to 5Ghz (only) and 20 channel width with theoretical and optimal RF conditions

AP: Single R500

How many concurrent clients can I serve with for example a Netflix 5mbps stream?

What is the formula / model?
Thanks

When is airtime fairness scheduled to be fixed in 5GHz?

It's said to be 10.0. I have no idea when that will be released.

I didn't realize that airtime fairness was missing from the R500. (at the current firmware release) This makes it much less suitable for streaming (downloading) video. (on 5Ghz)

Note: AFAIK: Airtime fairness applies to *downloaded* traffic.
All it takes is for one user to *upload* a large file to potentially monopolize "all" the airtime on a given channel.
I have not noticed Rucks (or any vendor) rate limiting client transmissions.

Most traffic is downstream so this usually isn't an issue but every once in a while this can kill WiFi performance.

@ David - I am unsure and we have not yet been given and firm dates towards commital on ATF from Ruckus for the r series AP's.

@ John - I think that might creeeeeeeep a little 🙂

@ Bill - I thought they normalised across DL and UL in regards to ATF, I cant remember 100% for sure, but I'll find out and let you know.

I thought so too for ATF. I don't know if QoS / heuristics does as well on uploads though or for controlling upload vs download balance.
