Voltaor voice-over LTE, is a technology that more and more mobile operators are starting to implement in their own networks, the company Apple Lossless Audio CODEC (ALAC), intending to provide support for it in iPhones. Confirmation is coming via some offers for jobs published by Apple Lossless Audio CODEC (ALAC), in its own website, the company is looking for engineers specialized in Volta, IMS and beyond.
The company is currently advertising for a cellular systems protocol engineer, calling for experience with "VoLTE" and "IMS." Other positions are calling for experience with the Session Initiation Protocol (SIP) protocol. Apple is also looking for a senior baseband engineer to work on "cutting-edge" audio for its devices, which will include the Adaptive Multi-Rate Wideband (AMR-WB) speech compression codec, which is part of the VoLTE specification. The engineer will help to "implement, port, and deploy AMR-WB, AMR-NB, CELP, EVRC-B, EVRC, EVS Vocoders, and Jitter Buffers on Mobile devices," according to the ad.
Although for now Volta is a technology in the early stages of global adoption, the company Apple Lossless Audio CODEC (ALAC), is interested in providing support for it in iPhones, maybe even starting with iPhone 6. Now those at Apple are looking for engineers specialized in working with this technology and since it should be widely usable by next year, the chances that the iPhone 6 will include support for it are high.
The even more interesting part is that this support for VoLTE could also be extended to the iPhone 5, iPhone 5S or iPhone 5C, considering that the modems of these terminals allow making voice calls via LTE. Of course, no one knows if Apple will decide not to offer this function exclusively for the iPhone 6, but it is certain that the hardware in 2-year-old iPhones contains support for VoLTE.
