It is a long weekend with workshops, lectures, games and socialising for german hackers in an old amunition factory, now used as an art college. Since the event is free of charge, there are not alot of funds available for infrastructure.
Last year I had 2x Omnitiks and 6x RB751 in use to provide wireless. While everything worked, 5GHz coverage could have been better. Also I had some stability issues with the RB751s until I simplified the configuration to include only the bare neccessities.
I stumbled across the RB912 myself already (http://shop.meconet.de/Hardware-compone ... 16011.html
). It would defenitly be a great choise, if it would have been release already. So I guess I have to use either Omnitiks and RB751s or build a 2,4GHz & 5GHz integrated solution myself using (quite expansive) RB433 boards.
By the way, how many clients can be connected to a single RB751? - I am just wondering, if I can spread the devices out a little to cover a greater area ...
