Advanced Technologies for LTE Advanced
With the explosive growth in mobile data traffic fueled by smartphones and mobile applications, transition from the 3rd Generation (3G) toward 4th generation (4G) cellular networks is progressing at an unprecedented pace. Since the first release (release 8) of the 3rd generation partnership project (3GPP) Long Term Evolution (LTE) standard in December 2008, LTE has become the de facto standard on the way toward 4G cellular networks. Accordingly, LTE networks have seen rapid growth since 2009 when only two networks were initially launched. The number quickly expanded over the next few years, currently reaching 89 networks across 45 countries.
