With an increasing number of subscribers logging on to the Internet to access and download data on mobile devices, mobile data traffic growth is doubling every year. In fact, Nokia Siemens Networks expects that at current rates, by 2011, mobile data will overtake voice traffic*, growing exponentially until 2013. Keeping pace with this rapid growth is Nokia Siemens Networks- the company has reached the 500 million mobile data user milestone, accounting for roughly 40% of global mobile data traffic today.
Driving Nokia Siemens Networks’ leading position in data is the company’s range of packet core solutions that allows operators to handle a huge number of mobile consumers, even if they are using data services heavily, with a very small amount of network equipment. This combined with technical innovation, such as Direct Tunnel, which provides operators with a simpler “flat” connectivity architecture, makes scaling with growing traffic much easier and more importantly, commercially viable.
“We realized early on that to help operators prosper, we would have to be innovative,” said Jrgen Walter, head of Converged Core, Nokia Siemens Networks. “While we can see that data traffic is rocketing, operator revenues are not. This means focusing on lowering the cost of data delivery. We have pioneered Direct Tunnel technology to provide an intelligent connectivity short cut for massive volumes of data that will deliver significant value to our customers.”
Direct Tunnel leads the way to a fully “flat” architecture, which is the target architecture for Evolved Packet Core and Long Term Evolution as well.
Close to 300 customers use Nokia Siemens Networks’ packet core solutions including operators such as America Movil, AT&T, NTT DoCoMo, Oi, Telecom Italia, Telefonica, and Vodafone.
