Hi everybody,
I've been working for some time in testing batman-adv protocol with several network topologies, and different network communications. Right now, I'm trying to build a batman mesh network over 5GHz wireless modules. However, I'm getting errors when trying to configure the module to use one of the 5 GHz channels.

I'm using a module with Ralink RT5572N chipset. Searching in internet, I've read a few comments suggesting that it's not possible to configure a 5ghz module in ad-hoc mode due to some kind of regulatory reasons.

Any of you have managed to get batman-adv working over a 5 ghz wireless network?

Thanks!

yes, batman-adv on 5 GHz works for us.

There are regulatory limitations for the higher 5GHz channels, but channel 36-48 should have no restrictions for ad-hoc use - if your chip/driver supports it.

I would suggest to first look into getting Ad-Hoc mode working without batman- adv before continuing any further. You might need other sticks, but there are definitely USB chips out there supporting Ad-Hoc (you may want to check out ath9k_htc based ones).

Cheers,
Simon

can you suggest ath9k_htc usb-sticks with 802.11a/5GHz?

I can't help with your specific issue, but I have personally configured an ad-hoc batman-adv mesh on 5GHz in Australia using TP-WDR3600 routers.

it's all about 'ath9k_htc' which is for atheros _USB_ sticks.

This depends on the regulatory domain you are in or using. In general batman on 5GHz works.

For example in Germany the lower 5GHz frequencies are free to use indoors. And Ad-hoc works there perfectly fine (of course batman as well). The upper channels require radar detection. This also means that the channel of the ad hoc network has to be changed as soon as any radar was detected. This is more difficult. I am not sure if any implementation for this exists in Linux.

Best Regards,

Markus
