Yeah, but the data usage is all asynchronous stuff, not especially delay-sensitive. It can be shipped in large packets. Voice isn&#x27;t YouTube; it can&#x27;t be buffered (much), so it&#x27;s a hailstorm of a very large number of very small packets[1] that all have to get there in a sufficiently quick, reliable and ordered fashion as to approximate the circuit-switched experience. That changes the physical layer oversubscription economics significantly.<p>[1] A typical &quot;packetisation duration&quot; in wireline VoIP is 20 ms. That&#x27;s the duration of audio buffered into a single RTP frame.<p>Edit: I&#x27;m not saying definitively that it&#x27;s not physically possible to deliver high-bandwidth voice conversations for everyone as table stakes. I&#x27;m ultimately a fixed-line guy and not in a sufficient position of knowledge in wireless&#x2F;RF to know that for sure. I only meant to say that there are known questions about its realism.
