Apple hiring may be prep for VoLTE phone calls

Apple recruits with VoLTE-friendly IMS in mind

Multiple job listings at Apple this week have hinted that Apple is getting ready to support Voice over LTE, or VoLTE. Telephony software engineer positions ask for experience with IP Multimedia Subsystem (IMS), the foundation for VoLTE's purely Internet-based calling. They're also asked to know related technology, such as the common VoIP protocol SIP as well as real-time transport (RTP).

While speculation has been raised that Apple would use the switch to pure IP-based networks as an opportunity to implement its own format for voice calling, the recruiting is likely just in preparation for carriers implementing VoLTE themselves. Apple often prefers to develop its own technology when it can, but it will also need to support the same voice standards as other devices and offer at least some cooperation with carriers.

We have tested VoLTE ourselves, and it provides a noticeable improvement over traditional CDMA, GSM, or UMTS (3G) voice calls. The quality is closer to that of a good Skype call than conventional cellular.

VoLTE is still being finalized, but the first devices could be as ready as soon as late 2012. Most American carriers working on VoLTE have been aiming for 2013, which could give Apple enough time to implement the standard in future iPhones. [via LightReading]

    First step toward "real 4G"

    Re: "The quality is closer to that of a good Skype call than conventional cellular."

    Glad to hear it. Some time in this decade, hopefully, we'll see real 4G rolled out. 100Mbps highly mobile, 1Gbps walking around and stationary. Voice and data will be combined into a single IP packet stream. No more separate, parallel network technologies for voice and data as with 3G and LTE (aka 3GPP Long Term Evolution.)

    VoLTE is one of the first baby steps toward that future.
