[B.A.T.M.A.N.] 5Ghz ad-hoc network for batman-adv

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!
