All,
It seems an alarmingly high number of wireless devices have returned
to our campus this week. After at least of year of steadily increasing
numbers, we are now seeing a roughly 40% increase since last December. At
first I didn't believe what I was seeing and opened a case with the
If you saw Apple's earning's they sold a ton over the holidays. It wouldn't be
surprising to see a significant increase in wifi devices on higher ed campuses.

Same here, I've had to expand subnets for 15 buildings since the semester
started (we give each building a subnet), and looking at the logs I've got
another 5 or so that will need it in the near future. More buildings that used
to be good on a /24 are requiring a /23, and buildings that had
We had room for 6k concurrent users before xmas. That's was bumped up to 10k
over the holidays and we're seeing 11k trying to associate at timesso we
still don't have enough...

We are experiencing the same issues at here at Valencia College. On our larger
campuses or average went from 1000-1500 to 6000-8000. We changed our
authentication from BlueSocket to SafeConnect and we had the same concerns and
had the vendor validate the counts. Our only thing we can think of
We're seeing some of it, as well. Here at Rice University, we've seen an
increase of approximately 800 network devices on wireless from 4 Dec 2011 to
today. Our total on wireless 4 Dec was 6917, and on the 22 Jan 2012 it was
7794.
Our wireless is primarily split between authenticated and
For us, the swell in mobile devices started after Black Friday this season. I
have tracking that covers four years. There was a slight adoption of mobile
devices following Christmas 2 years ago, last years significant growth began
just before the holiday but peaked afterward. Mobile has roughly
We are seeing a high number as well but it is in the anticipated
increase. We have everything from clocks using ip to IPtv and all things
wireless. We generally try and stay ahead of it or at least not fall
behind on our wireless. We anticipate a reduction on wired devices by
90% next year and
Hi Don,
Can you give actual numbers? I only ask because 40% can sound huge, but depends
on where you started from and you have me curious.

We've seen an increase in number of devices associating as well.
Nothing nearly as impressive as everyone else's numbers in terms of
total quantity, but the jump for us from peaks of 300 associated to over
400 associated clients is definitely noticeable.

Don,
Yes same for us...Lots of mobile device...Everybody got a smart phone or a
tablet for Christmas. It makes up to at least half of our average 7K users per
day.

a.) our peak is in the late lunch until dinner
b.) a trick that I use to measure pool utilization is to watch the 'lts'
numbers in local3.log as my peered DHCP servers balance the pools. (I also
monitor leases and calculate pool fluxuations - but that takes longer to
explain).
Randall Grimshaw
please let me clarify... I think of these as the 'lts' messages... but the free
and backup numbers are what you would actualy reference. My apologies.

Our peak usage tends to be between 1pm and 7pm Monday-Thursday. We have about
8k concurrent users during those times.

Here's my Airwave graph for comparison and now represents 11,000+ users.
The really surprising increase in the middle group (green) which is my
captive portal. This has been a steady ~1800 average over the last year,
now pushing 4000.

We have not seen a huge increase in our wireless usage since the winter break
(right around 10K devices max). Maybe all of our users already loaded up on
their devices over the summer?

I would be interested in any research into mobile device IP address consumption
folks could point us towards. We see curious address consumption behavior by
mobile devices, but have not done the testing to determine if it is the
device's OS consuming all the addresses (iOS is our campus'
