I'd like to do some low bandwidth realtime* streaming to a Raspberry Pi Zero W. Since the required bandwidth is much lower than even the lowest WiFi speeds, but dropped packets and jitter will cause problems, I'd like to configure the WiFi link to use a fixed, low bitrate.
Is this possible, and if so, how?
* For those not familiar, "realtime" means a late packet is a useless packet. Think of something like a phone call: a re-transmitted packet that arrives late is worthless because the audio has already played past that point. For this reason, reacting to failures isn't a very good option: more important is to avoid the failures in the first place, even if that means sacrificing maximum attainable throughput.
