Comment on Benchmarking latency across common wireless links for microcontrollersparent

Comments

Analogue would be nice in that regard but wouldn't it be pretty bad with interference, signal quality over distances etc?

It worked that like for many, many years (radio mics) before digital came along. Think of FM radio - if you have a good signal, it's pretty resilient to interference and in a controlled short range environment it is extremely reliable.
