Lets look at a non university example.<br>
<br>
IGF Baku.<br>
<br>
Attendance was above that expected - around 1500 to 2000 people.<br>
On the pre-opening day, there were however only 500 people- and the WIFI<br>
worked fine.<br>
<br>
I think the organisers banked on about 1000 people - and they had a /22<br>
available.<br>
<br>
This they eventually changed to a /21.<br>
<br>
There were still problems.<br>
<br>
I had both a Laptop, Cell phone and iPad with me. My cell phone has<br>
WhatsApp on it. I do roam but International Data roaming is very<br>
expensive, so I just allow my phone to use the local Wifi. (Even at<br>
home, I keep the Wifi on, software updates can really eat into a 3G data<br>
bundle).<br>
Whilst in meetings, I usually use my Laptop, but the Apple iPad is on<br>
(despite the screen being blank - etc). So most of the time I am using<br>
three IP addresses. I don't consider myself to be particularly unusual.<br>
For example, so many people have more than one cell phone.<br>

I'd consider allowing a University to state what ratio they'd like to<br>
use. (1:1, 3:1, 5:1) - but for now nothing higher than 5:1 unless they<br>
can provide additional justification. I'd be surprised if universities<br>
did not go for a higher ratio, they may pay more though - and I do<br>
believe that the future is multiple devices.<br>
<br>
I wouldn't worry about a non-utilisation problem - unless we suddenly<br>
here of that University trying to sell unused IP's.<br>
