Data usage on smartphones delivered mostly by Wi-fi


By 2015, Juniper analysis predicts that 63% of data will be delivered to smartphones by wi-fi and femtocells versus over the mobile networks (here's Silicon.com's Cheat Sheet on femtocells).

The quantity of data required will be 14,000 Petabytes (1 Petabyte = 1 million Gigabytes). This is an eye boggling amount of data - equivalent to 18 billion film downloads or 3 trillion music tracks. This is 'chunky' - Apple recently purchased 12 Petabytes of data from Isilon Systems, rumoured for video storage for iTunes.

There are two opposing effects here in mobile data:
  • users using wi-fi for browsing / increased wi-fi penetration
  • fixed to mobile substitution - ie people pitching their fixed line data connection for all mobile data connection

So the net effect is pretty big data chomping, but not as bad as mobile world feared some time ago.
