Here is a snapshot of a peak hour (1:00 -2:00PM) wireless client distribution in my campus network over past 2 years. It almost ~150% growth of number of  devices connected to the network over wireless.

I would like to see another color (802.11ac) into this graph from Q1-2014 onwards.

LTU-Wireless-GrowthHere is the number of devices distributed per user on a random day. Average 1.4 devices per user.

LTU-Wireless-Growth2Here is the client distribution per protocol on this day. More than 85% users are having devices supporting 802.11n.

LTU-Wireless-Growth3Are you ready with your wireless network to meet these sort of demand ?
