Worldwide mobile data bandwidth usage increased by more than 70% during the second half of 2009, drven largely by over-the-top applications like YouTube and Slype.

This is according to the Allot MobileTrends: Global Mobile Broadband Traffic Report, from Allot Communications and based on Dynamic Actionable Recognition Technology (DART).
Asia-Pacific APAC leads the growth with 86%; EMEA posted 70% growth and the Americas 59%.
The Allot MobileTrends Report validates video as a mainstream medium and demonstrates that it is the single most influential factor driving the need for increased mobile network capacity.
However, with peer-to-peer (P2P) remaining the biggest cause of cell congestion in the top 5% of cells, mobile broadband networks are still facing the same challenges as fixed networks – growing bandwidth demands, congestion, as well as finding ways to enhance the user experience and to lessen the negative impact of a few subscribers on the network.
According to the Allot MobileTrends Report:
* HTTP streaming continues to be the fastest growing application with a 99% increase; its global mobile broadband share grew by 50% between Q2 and Q4, 2009;
* YouTube accounted for 10% of global bandwidth during the third and fourth quarters of 2009;
* FaceBook experienced tremendous growth of 180% during the second half of 2009;
* Skype is the undisputed VoIP traffic market leader, accounting for 77% of the global VoIP bandwidth; VoIP and instant messaging applications have increased significantly by almost 47%.
* HTTP downloads grew by 73%, and have become a feasible alternative for massive file sharing; and
* P2P is the single largest factor leading to cell congestion which accounts for 34% of bandwidth utilisation in the top 5% of cells.
"Our MobileTrends Report is a valuable tool for mobile network operators who need insight into subscriber behavior across applications and regions," says Rami Hadar, president and CEO of Allot Communications.
"It highlights how mobile data services are evolving and the extent of their influence over the subscriber, which in turn, helps the operator understand the significance of adapting their networks for the continued demand for optimised bandwidth."
