Hi,
http://www.wlanprosconference.com/ (it's sold out but they have a waiting list
for replacing no-show attendees)
I'm attending and for me it would be great to meet other edu WLAN admins!
Best regards, Kees

Yes I'll be there.
Actually I will arrive almost 3 days head of the Conference if someone is up
for some sightseeing. Need to adjust from GMT. ;)

As this technology begins to be deployed is anyone out there planning ahead for
wave two of this? I know it's not going to happen for a while but I'm curious
if there are folks in the process of new construction where you have the option
to add the infrastructure now to support the 10Gbps. If
HI Joe,
We are moving ahead with and future WAP installs using 2 x CAT6A per the
upcoming/pending TIA TSB-162-A recommendations approval:

Call me naïve, but I think 10 gig uplinks for ac WAPs is serious overkill. We
have almost 4,500 switches across campus, most with 1 gig user uplinks, and the
vast majority are perfectly fine with 1G (heck, we could swap a good number of
those for 100 Meg, and they'd barely notice). These are
BTW... Before anyone jumps on me, I understand the purpose of the question.
It's great to know the best practices for the 'what if' situation.

We've decided for now to run two Cat6A to every AP for new construction. This
is because right now it is not clear if vendors are going to utilize two Gig or
one 10 Gig connection for each AP to support the theoretical oversubscription
of one Gig by Wave2 and beyond. One of the challenges is
The WLAN industry is doing an absolutely horrible, almost shameful job of
managing the message on cabling for 11ac, says I.

I swear, just a couple months ago I saw a post on this listserve that you
should run TWO Cat6 runs for every 802.11ac AP. Now, CAT6A?!

6A isn't particularly more expensive in a new build / whole area refurbishment,
and I figure the 'fit the best you can afford' route works for the best chance
of it still being adequate in 20 years time.
My predecessor who shared this view did us a huge favour by insisting on Cat 5
when Cat 3
Thanks everyone for the ideas/posts concerning this. It seems crazy to me as
well, but it doesn’t hurt to be prepared when preparing for future construction
projects. Heck we haven’t even deployed any first wave 802.11AC yet but will
be shortly.
Thanks,

And the WLAN industry also does strange math ;-)
A lot of services are going to the Cloud, mostly using your pipe to the
Internet.
It seems that, progressively or even rapidly, the limiting factor is not Wi-Fi
anymore but rather the pipe to the internet.
1 Gbps to each Wireless AP is a lot of
They certainly are using some strange math, my experience (and that of other
institutions nearby) is that the vast majority of my N access points don't
suffer from being connected to 100M poe switches, and in the places we have 1G
to them, they generally don't use more than 100M.
Thanks

Is much marketing foo-foo, in my opinion. The wired-side truth of the Wi-Fi
story deflates a lot of the numbers that are meant to dazzle…

I would say take a close look at the 100M ports connected to your N or AC
APs and check for output drops. We've seen this in some locations where we
we're careful about refreshing with N AP's. It likely comes at peak times
so if you're just graphing the in/out you will miss it.

What is it you think is happening during output drops?

The packets being dropped on the way back to the AP because they're
overrunning the 100M interface during peak wireless usage. You'll also
notice if you do a speedtest that the download is much worse than the
upload. We seen this disappear when we swap in a gig switch.

There is also the option, if you're a vendor that owns both ends (AP and
Switch) to do something creative with only a single Cat5/6.

Years ago I “got creative” and made some patch cables that allowed me to put
two 10M hosts on a single jack instead of pulling new cables. The boss said
unkind things and shoved a notebook of the TIA-568 spec in my face. Ah, the
bad old days…;-)

That was a standard across the AMP jacks... you could get one Cat5
100Mbps, or two 10Mb split cable jacks. It was a matter of which
insert you plugged into the socket.
It wasn't my decision, and I cringe everytime I see one, but they're
still around in our older campus buildings.

We had thousands of those, wired for usoc on the wallplate side, a splitter
to send 2 pairs to two station cables with usoc on one and 568b on the
station end. We had this for our entire cat-3 plant, and some of the
early cat-5 (non-e) terminated on 110 blocks. I don't miss that any more
