It's official. T-Mobile is deploying Enhanced Voice Services (EVS), a successor of the current mobile HD voice codec AMR-WB. EVS uses complex speech compression algorithms and was designed to provide higher-quality audio than is currently available over cellular networks.
While T-Mobile US executives are busy this week challenging what rivals AT&T and Verizon are doing in 5G, they're also touting their own network progress and saying that they will be there in 5G as well, all in good time.
LOS ANGELES-- A top T-Mobile US executive told FierceWirelessTech that roughly 33 percent of all of the carrier's voice calls are now transmitted using Voice over LTE (VoLTE) technology. That's a notable milestone considering T-Mobile first launched VoLTE in May 2014 in Seattle on a trio of phones.
BARCELONA, Spain--T-Mobile US CTO Neville Ray said that 5G networks will mainly involve new uses of spectrum to address continued expected growth in mobile data usage and different uses cases, including from the Internet of Things.
