Voice over LTE could slash smartphone battery life in half

Wireless providers in the United States see voice over LTE, more commonly known as VoLTE, as the future of mobile phone calls. The transition to the new technology may not be well received by consumers, however. According to a new report from Spirent Communications, VoLTE can reduce a smartphone’s talk-time battery life in half, Fierce Wireless reported. The research firm came to its conclusion after using a smartphone capable of supporting both CDMA and VoLTE voice calling on an unnamed U.S. carrier’s network. When making calls over VoLTE, the smartphone’s battery was reduced to 50% or about 252 minutes of talk time. More →

Qualcomm performs the first successful voice-over-LTE call with handover to WCDMA

Verizon, AT&T and any other LTE providers currently rely on 3G networks to carry voice phone calls. In the future, carriers hope to use voice-over-LTE (VoLTE) technology, and Qualcomm recently reached an important milestone on the road to making VoLTE a reality. Qualcomm announced on Thursday that the company had successfully completed the “first voice call handover from an LTE mobile network to a WCDMA network using Single Radio Voice Call Continuity (SRVCC).” The company, while working with Ericsson, used its own MSM8960 Snapdragon S4 chipset to power the test hardware, and the technology will be demonstrated live at this month’s Mobile World Congress in Barcelona.

Verizon confirms VoLTE plans for next generation voice network, video calling

Verizon has confirmed to CNN that it will utilize Voice Over LTE (VoLTE) for its next generation voice network. The company is expected to make a public announcement, and host demonstrations, at next week’s Mobile World Congress. In the future, Verizon hopes to route all voice and video calls, text messages, and data packets over its LTE network.

“Calls between VoLTE-equipped smart phones will sound better,” notes Verizon. “The ‘high-definition’ audio fidelity will be a major selling point.”

The report also notes that VoLTE will allow simultaneous voice and data usage — a capability currently unavailable to most CDMA handsets. Verizon declined to comment on how it plans to price and roll-out VoLTE, but we’re sure it will be a slow transition. Hit the read link to check out the full report. More →
