Mobile data will overtake voice traffic by 2011, predicts
Nokia Siemens Networks, which has just notched up its 500
millionth mobile data user.
Jürgen Walter, head of the company's converged core networks
business, said the
growing popularity of mobile broadband services and
machine-to-machine applications would create an exponential rise in
the number of bytes of data traffic carried by mobile packet core
networks worldwide.
"This will result in a yearly doubling of data traffic from
almost 400 petabytes (400 million gigabytes) a year in 2009 to
almost 2,000 petabytes (2 billion gigabytes) a year by 2011. This
would overtake the estimated 1,200 petabytes volume of voice
traffic.
Walter said its customer base of close to 300 network operators
served half a billion users, which meant Nokia Siemens Networks
carried about 40% of the mobile data traffic.
