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, Franz
