10,000% Mobile Bandwidth Increase by 2015 is Just One Problem, Nokia Siemens Says

 Mobile data from smart devices will increase 10,000 percent by 2015, says Rajeev Suri, Nokia Siemens Networks CEO. And that's only part of the problem. The other issue is signaling overhead, apart from bearer traffic, that can tie up radio ports even when not much actual bandwidth is being consumed.

That's one reason "adding capacity" does not solve all congestion issues in a mobile network. Congestion also can occur when signaling load is heavy. But bandwidth growth is an issue.

Nokia Siemens Networks predicts that by 2015, annual mobile data traffic will reach 23 exabytes , equivalent to 6.3 billion people each downloading a digital book every day.

Pure capacity is just one issue, however, intermittent connectivity and shifting locations plus signaling overhead are problems as well.

As an example, having predicted the current surge in smarter mobile devices, Nokia Siemens Networks is the only vendor to have 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, says Suri.
