Marcel is this correct? Inaky -- how about uwb, or >WiMax? UWB swipes over all the bands (from 3.1 to 10.6G), but keeping emission below FCCp15 limits (-41dBm, if memory serves) so it looks as interference to others. All the channel assignments are fixed and known, so in theory, it'd be possible to coordinate. On WiMAX the bands are allocated per country and per operator, so if the device can tell us what it supports or what the operator is telling it to use, it should be possible for it to report it to some band controller for coordination, but I don't know if it'll make any sense to ask the device to use only bands so and so, because the knowledge of what's allowed is in the network side. I might be missing the crux of the question though :)
