(Which is a _device_ class) If they run on two different PANs: Create two wpan interfaces on top of one wpan phy. ---- But so far I remember it is some crazy "I can transmit on different pans with internal channel hopping by doing hardware offload" (It's still _one_ radio, in sense one transmit/receive medium) then do: nothing of that above - this need to be handled by some internal subsystem handling, if a use case exists. - Alex
