By 2015, annual mobile data traffic will reach 23 Exabytes – equivalent to 6,3-billion people each downloading a digital book every day.

This is according to Nokia Siemens Networks chief executive Rajeev Suri, speaking yesterday at the Mobile World Congress in Barcelona.
Suri outlined the changes required by mobile operators to cope with the huge rise in mobile traffic caused by smart devices, cautioning that if the blunt “just add capacity” approach used by many vendors goes on, most networks will be brough to a painful, grinding halt.  
He explains that the unique properties of mobility – such as intermittent connectivity and shifting location, coupled with the increasing range of smart devices – require mobile broadband networks to be far more intelligent in their handling of traffic growth.
As an example, he says that Nokia Siemens Networks predicted the current surge in smarter mobile devices and has built into its networks an industry standard – already common in smart phones – that allows it to reduce unprofitable, congestion-causing signaling by three times while increasing smart device battery life.
