Features that control/improve the throughput like beamforming or
rate-control aren't influenced by batman-adv. Those are features inside
the wireless driver. Just between batman-adv and the PHY-Layer in the
network stack.

I might not have enough experience with 802.11ac devices but if you have
a large scale outdoor network with big distances between your nodes
(hundreds of meters to kilometers) there might be not a big difference
between 802.11ac and 802.11n.

But if it's a smaller scale indoor network with lower distances and
lower noise floor there should be a higher throughput with 802.11ac.

Kind regards,
