A new set of job listings noticed by LightReading continue to show Apple’s focus on implementing VoLTE, or voice-over-LTE, support for including high quality call quality on new iPhones.
Specifically, the job listings seek both a Cellular Systems Protocol Engineer with hands-on experience in wireless technologies including VoLTE and an iOS Wireless Communication Software Engineer with “SIP, RTP, and VoIP related protocols”, showing the company is continuing to beef up its expertise around the technology.
While data has been handled over the latest generation LTE networks since the release of the iPhone 5, voice calls have still relied on using older 3G networks for handling calls. Support for VoLTE would have the effect of increasing call quality by taking advantage of the newer networks.
Carriers in the United States have already began sharing details about their plans to roll out support for voice-over-LTE. Verizon announced earlier this month that it plans to launch its VoLTE service the the last quarter of this year. T-Mobile shared last month that its VoLTE service now covers 100 million people while AT&T has also announced VoLTE support.
