VoLTE

Rumors have been swirling for a long time about what HTC might have planned for us this year, and while the Taiwanese company isn’t telling us just yet, they’re at least giving us some kind of idea of when exactly they’ll be making some big announcements. To no one’s surprise, HTC is today sending out invites for a press event being held at the Mobile World Congress in Barcelona this upcoming March.

Verizon Wireless has announced its plans to launch support for Voice over LTE service (or VoLTE) on its cellular network later this year, according to FierceWireless. However, the company says it has moved back its plan to release a VoLTE-only phone until 2016, and will continue releasing CDMA-capable phones until that time. Such a device was originally anticipated for the end of 2014.

The carrier originally announced earlier this year that it would support the new voice service, which provides higher-quality phone calls by utilizing high-speed data connections, but declined at the time to say exactly when it would happen. Other U.S. carriers, including T-Mobile and AT&T, have already started rolling the technology out in select markets.

Following announcements earlier this month from both AT&T and Verizon, T-Mobile announced today it’s introducing Voice over LTE support starting with Seattle. The first three devices to support the new tech include the LG G Flex, Samsung Galaxy Note 3 and Galaxy Light.

So I’m thrilled to congratulate my team on the launch of Voice over LTE (VoLTE) in the Seattle area for our existing LG G Flex and Samsung Galaxy Note 3 and Galaxy Light customers. Our friends at MetroPCS were the first to launch VoLTE in the U.S. back in 2012, and we’ve been working hard on a LTE Advanced version of VoLTE, which we plan to roll out to more T-Mobile customers throughout the coming year.

T-Mobile’s CTO Neville Ray noted that the new technology, which brings voice calls onto the same LTE radio layer previously reserved for data, will allow “faster call setup times (almost twice as fast as a non-VoLTE call setup) and the ability to enjoy lightening fast LTE data speeds while on a call.” It will also support the HD Voice or wide-band audio feature supported lots of newer hardware. Ray explained how the technology works:

Earlier today, Verizon revealed that it will launch its nationwide VoLTE service across its massive network later this year. If you’re unfamiliar with the terms “voice over LTE” or “VoLTE,” it’s voice calls between two compatible devices being placed over a wireless carrier’s LTE network. To do this, Verizon will be using the Adaptive Multi-Rate Wideband (AMR-WB) speech coding standard to provide its customers with high-quality voice calling. In addition to voice calls, Verizon’s VoLTE will feature video support. This will let users place and receive video calls directly from their contact lists.
