We do run with wmediumd, although I hadn't looking into this much. The README claims to support frame delay: "wmediumd allows simulating frame loss and delay." But I can't actually find a way to configure that. It only seems to have configuration values for frame loss between stations and SNR, no explicit delay. If a delay is possible it would be easier to integrate this into our current test setup.... > > Or adding some kind of fake air latency into hwsim. ... if wmediumd doesn't support a frame delay then this may be the route we have to go.
