Hello Sven:
Thanks you for your advisement , and i will start via two Rt2070 at first , but i will purchase suitable wifi network card or wifi module recently ,
Whether Atheros (AR54xx、AR91xx、AR92xx、AR93xx及AR95xx) will be suitable for batman-adv ?
their driver is ath9k .
Have a good day with you
Best Regards
Tiger

Hello Dear Sir :
Whether Batman-adv need suitable wifi network card (support interface modes ( mesh point ) ) .
"mesh point" is for 802.11s. You can use 802.11s (mesh point) interfaces for batman-adv when you set mesh_fwding to 0. But most people use IBSS (adhoc) at the moment for batman-adv. It doesn't really care that much about the underlying interface. It just has to be ethernet compatible and support some basic features like broadcast.
So you could even run infrastructure mode (AP+Sta) with batman-adv. But it doesn't make a lot of sense in most situations :)
The B.A.T.M.A.N. V algorithm implementation has some extra requirements. It must be able to get the expected throughput towards a different device from cfg80211. You can check if the driver supports this by checking `iw dev wlan0 station dump` and searching for "expected throughput:". The Mpbs value should represent the reality (and not be complete bogus).
The biggest problems here are driver/hw bugs. Even the ath9k hardware (which works quite well) has its fair share of problems.
there are two wifi network card , and i thought Rt2070 will support Batman-adv .
Because Rt2070 will support interface modes ( mesh point ) , and RTL8188CUS can't support interface modes based mesh point .
Both advertise support for IBSS. So you can (in theory) use adhoc on both devices and run batman-adv on top of these adhoc interfaces. But you may end up with driver problems (at least I already had problems with Realtek and Ralink hardware). Maybe someone else here already tested these two chips and tell us more about them.
Kind regards, Sven
