A modern smartphone is a convergence of two devices: a PDA and a cell phone (this is more obvious with older devices like the Palm Treo 650). Once the telephone bit is no longer relevant (probably replaced by a data-only cellular modem), it will go back to being just a PDA.

- emeril 4y agopretty sure that call audio gets much better prioritization for low latency (though at relatively low bandwidth) than higher bandwidth non-voice data?
- simfree 4y agoThe QCI (QoS Class Identifier) for carrier provided voice and video (Android only) calls is generally much higher than normal data, and carriers monitor call handoff reliability between towers, Mean Opinion Scores (MOS, a rating of the audio experience of each call), and device specific performance.
