Hi, There's some work done on the ath(4) hardware for 11a parts done by Sam Leffler. I fixed it for 11n parts. It's in FreeBSD-HEAD. I figured out how to get it mostly working on the AR93xx/AR94xx parts too but it turns out there are some significant hardware changes in how the MAC schedules packets that a whole lot of work needs to be done to get effective TDMA on those parts. If you're interested in it I can brain dump where I was at with it! -adrian On Fri, 12 Apr 2019 at 01:51, Stephen Patrick <stephen@cablefree.net> wrote: > Thanks Adrian, > > We are interested in "long range outdoor" (10-20km) with high gain > antennas. > Do you know "Mikrotik Nstreme/NV2" and "Ubiquity Airmax" ? > Those have framing/polling done in software - wrapped around the wireless > driver. > Is there equivalent developed in FreeBSD? > > Best regards > > Stephen > > > On Thu, 11 Apr 2019 at 20:52, Adrian Chadd <adrian.chadd@gmail.com> wrote: > >> hi! >> >> I know that a lot of the 11ac chips do TDMA but the vendors keep the >> implementation and knobs close to their chest.
