No. As mentioned in previously, the UNII bands are bundles of channels which share the same rules, so since channels 6 is not in the same UNII band as channel 36 it is not allowed to instantiate a GO on channel 36 based on the GO concurrent relaxation. > Is the definition of concurrency GO thing supposed to *restrict* the number > of interfaces a device can create (STA, GO), or simply define permissive rules > which would have otherwise been blocked? > The definitions to not limit/restrict the number of concurrent interface but allow permissive rules to allow certain operations which in other circumstances would be blocked.
