Cisco's "Visual Networking Index" predictions of fixed and mobile data traffic are some of the most widely-cited charts and qualitative predictions in the industry.
I'll go through it with a fine-toothed comb when I get a chance, but one thing sticks out immediately:
2014 = 63.9 Exabytes / month total IP traffic
... of which 3.5 Exabytes / month is mobile data (ie 5.5%)
What is not clear to me at first sight is what happens to femtocell and WiFi offloaded traffic - ie is it double-counted? Especially femto traffic, which is likely to traverse two sets of routers first in the fixed ISP's network, and then again in the mobile operator's own core.
(I'm assuming that the figures exclude double-counting "private IP" traffic, such as transport between cell sites and RNCs and the operator core, where provided via a 3rd-party wholesale network operator)
