WAN latency between AP and WLC in local mode

[paulgallant]

Hi,

WAN latency requirement is well defined in documentation when using H-REAP (300ms (version 6.0) and 2 seconds (version 7.0.116.0 and later)).

I cannot find recent update on the WAN latency requirements when using local mode. The only reference I found is:

http://www.cisco.com/application/pdf/paws/99947/lwapp-traffic-study.pdf

Can you explain what technical guidelines are when using local mode over the WAN?

Thanks,

Most of the documentation is going to assume that you have a WLC at the same site as the Local mode AP, so yeah very little reference information there.

So for running local mode across the WAN, I would still keep it to ~300ms roud trip, less if you are trying to do voice across the wireless, as it requires ~150ms round trip, IIRC.

For just data, you might be able to be a bit higher than 300ms, but that should be a pretty good baseline, and completely doable with today's infrastructures.

just my $0.378(increased for inflation)
