We're gradually working our way into an all-LTE world, but there are still a few hurdles to cross. One of those hurdles, the seamless handover from LTE to 3G during a VoLTE (voice-over-LTE) call, has now been achieved by Qualcomm.
So, what does that mean, exactly? Basically, if you're on a VoLTE call in an LTE network and you leave the coverage zone, the call would normally go dead. Thanks to this new chip from Qualcomm, though, that all changes.
