Could you give me some hints where I have to look for hardware and what kind of hardware I have to look for? I have the impression that there is something that I don't see in the whole story. I hope ad-hoc WiFi is still a technology that is up to date. Or is there a technology that replaces it?

Yes, IBSS is becoming a problem at the moment. You can try QCA ath10k hardware with Ben Greears firmware [1] or Mediathek with the mt76 driver [2] when you want up-to-date HW. There is still some ath9k based stuff around when 802.11n is enough.

Otherwise you might try to replace IBSS with meshpoint interfaces. Just setup it like 802.11s but with forwarding disabled [3]. This works at least with ath10k based HW and the official QCA ath10k firmware.

But HW which uses ath10k and other things which uses special firmware which prevents you from using your "own" rate control algorith are a no-go when you want to use throughput based metrics (as in B.A.T.M.A.N. V or olsrd2). Then you should stick either with ath9k or mt76 compatible HW.

Btw. my tests of mt76 showed performance and stability problems in the past. This may have changed by recent fixes in the driver but I don't know the current state.

Kind regards, Sven
