There’s a section (“Our motivation for building a new codec”) in the article that directly addresses this. Assuming you have >32 kbps bandwidth available is a bad assumption.
- nicce 2y agoThe best assumption would be that you either have connection available or not available. Then, if it is available, what is the minimal data rate for connections which are available in general? If we do statistical analysis for that, is it lower that 32 kbps? How significantly? For some reason, I would assume that if you have connection, it is faster than 2G these days.
- zamadatix 2y agoThe question isn't really the minimal bandwidth of the PHY rate it's about the goodput for a given reliability. Regardless of your radio there will always be some point where someone is at the edge of a connection and goodput is less than minimal PHY bandwidth. The call then turns choppy/into a time stretched robot you get every other syllable from. The less data you need to transmit + the more FEC you can fit in the goodput then the better that situation becomes. Not to mention "just because I have some minimal baseline of $x kbps doesn't mean I want $y to use all of it the entire time I'm on a call if it doesn't have to".

- nicce 2y agoNow that you mention it, Wikipedia seems to have interesting list about that. Seems like that by 2030, the most starts to switch off. https://en.wikipedia.org/wiki/2G https://en.wikipedia.org/wiki/2G
