In According to Ciscos Visual Networking Index there will be a 26-fold increase in global mobile data traffic between 2010 and 2015 a staggering compound annual growth rate (CAGR) of 92 percent. Operators realize that their 3G networks are not equipped to sustain this high level of traffic growth. They are looking to all-Internet protocol (IP) networks such as IP multimedia subsystem (IMS) and long term evolution (LTE) to deliver the bandwidth required to support data-hungry devices and applications.
