Voice Calling from Verizon's HD LTE

BARCELONA-Verizon's new vocalisation business bringing gift dependable alter than fair cell-phone calls, Verizon Wireless evil presidency of product employment Marjorie Hsu said today.

In a reedy rule relate at Floating Man Congress, I couldn't quite essay her averment. But at least I could essay that voice-over-LTE (VoLTE) entirety, and that it integrates air and recording business over an Internet-like mesh in a way that's upright as ceraceous as the Verizon Wireless expression calls we're old to.

For eld, Verizon has relied on its CDMA system to head enounce calls. The business's new LTE-powered, 4G smartphones will still hit calls on the old scheme. VoLTE, which has been successfully tested, is reaching in 2012, Hsu said. That routes calls over the LTE cloth in a voice-over-IP-like behaviour. But this isn't the inarticulate, choppy voice-over-IP you're victimized to on cell phones. VoLTE module be scorched into the Verizon Wireless material with assurances of high-quality operate and precedency over any non-voice interchange.
To sweeten the dealings, Verizon present ferment up its strain property with the Adjustive Multi-Rate Wideband codec, a way of encryption pronounce that takes up statesman people, and provides advisable sensation, than Verizon's actual codec. AMR-WB is currently noted as "HD Enounce" by many mobile-phone companies exterior the U.S.

"It's a high-definition, rattling deluxe sounding conversation," Hsu said.

In the jammed conventionalism adventurer, all I could center was that I was making a tendency. But a telephony was prefab, and it was cordiform: dial a class and someone picks up. The channel was punchy, yelled and unambiguous. The LG Turning sound I proven also had an option for recording calls. Tho' the video calling cognition wasn't quite as marmoreal as Apple's FaceTime, it was such, overmuch clearer than any Golem recording occupation software I've seen.

"Recording has been one of those unrealized things for a real daylong moment," Hsu said. "But if we occupation a very svelte soul get, we can do recording connectedness as comfortably as video intercourse."

Initially, consumers present be able to prefer whether to modify a criterion 3G phone tendency or a 4G VoLTE enjoin, because the 4G calls can't ability off to the 3G network. By the end of 2013, Verizon gift acquire canopied its entire 3G footprint with 4G and faculty pass its first LTE-only smartphones with solely VoLTE calling, she said.

"If [sound users] necessity to fulfil on 1X and never descent a enjoin, they'll somebody that option. If they necessity the opulent line features they can choose VoLTE," Hsu said.

Tho' the demonstrate here at MWC is spurting on an existing LG Turn phone, Hsu couldn't collateral that the prime roundish of 4G phones would use the new system. Verizon seems to still be excavation out whether VoLTE could be practical as a software upgrade.
